WL: TT 5.0 Coupe

[Coupelx]

After selling my second 2.3t I have found i am addicted to boost. So its time to put a little pressure on my 86 5.0 coupe. Yea its not getting painted this year either :lol:

It currently had a gt40 topend, Trickflow stage 1 cam and misc bolt-ons.
Its an AOD with 4.10s. Ive been told i will want to change gears but time will tell. For mroe details see my Garage.

Im looking for around 400-425 rwhp with god drivability. Should be easily accomplished!


Hitting up ebay and some turbo forums i have purchased the following:

1 ihi (still need one more)
http://www.robietherobot.com/storm/images/RSnTurboCoupeUG.jpg
They are smallish IHI turbos found on the 87-88 turbo coupes. should spool by 2500.

One of these to keep tabs on the AFR:
http://www.autocarparts.com/images/AEM/aem_guages.jpg
Wideband of course

These are the headers. they require a bit of modding to work with the accessories but for the $160 i paid for them who cares?
http://i3.ebayimg.com/06/i/000/9f/b4/f9f7_1.JPG

Of course gotta have the ricer BOV...
http://members.shaw.ca/gehca/pic/GR-O%20Bov2.jpg

Also bought another set of turbo flanges to use as spacers if needed but no pics of those.


In the next couple months ill get the intercooler, 42lb injectors (possibly 46lb low impedance with resistor packs), and the MAF meter and the little things like feeds and drains, couplers and clamps. then eventually a couple more guages and some misc stuff to round off the installation.

I am going to use my christmas money from my dad to pick up a tuner and associated parts from www.moates.net

im shooting to have it drivable by easter for the local rod run and a trip to the dyno around that time.

I hope to start mocking up stuff on a spare motor this weekend if the headers get here. Also i got the wideband temp mounted in the car. its pretty damn neat. Real pics to come!

[Yngvar]

look to be a nice set up

[Johnny]

looks good, though it looks like those headers are set up for a t3/t4 turbo, and that is not the same flanges as whats on those turbos...

not to mention they are stupid unefficent. You can get WAY better and more boost sooner and have a bigger efficency range if you dont try to cheap out on the turbos like you are doing now.

but good luck, should be fun

[CustomSSI]

if your only wanting 400ish rwhp you may want to look into changing some of those parts around.. Or are you trying to do it on a good budget too?

[Coupelx]

its on a budget of around 800-1k. the pic i posted is not the actual turbos, i have one off a 87-88 tbird. i know they are a bit small but with porting the wastegate hole many have made in excess of 400 rwhp with them. they will probably get switched out with something else this summer. probably some .60/.48 t3's.

custom ssi- the 400 is just a starting number. what would you recommend changing?


I hope to have pics when more stuff comes today or tomorrow.

[srt-4_uk]

If you buy a real HKS or TiAL BOV and you wont have to worry about it leaking boost like any ebay ones. I also have a 16g turbo if that would work for your setup.

Yup Yup ^^^^

[Coupelx]

a few people on turboford.org have used this bov with no problems. i pulled it apart when i got it and its definately built good. guess we will see when it goes together.

the 16g has a different exhaust flange.

[Coupelx]

a small peek:

http://img.photobucket.com/albums/v114/Fraggster/121307_221400.jpg

[86Shelby]

I would strongly suggest going with a .63 exhaust A/R on each of the turbos. The .48 will spool very quickly but will choke it down on the top end. Considering your 5.0 heads flow much, much better than our 2.2 heads and we don't have any trouble spooling a T3 with a .63 turbine housing and stage 2 turbine wheel.

[Coupelx]

lol thats not even a .48 t3. after seeing the size of this IHI i am strongly considering switching to t3's.

[Coupelx]

I got a few things done tonight. deciding to stay with the IHI's for now...

I took the IHI apart and cleaned it up to get ready to properly 'clock it'
http://img.photobucket.com/albums/v114/Fraggster/121807_190800.jpg

Apparently the mounting holes for the compressor housing are not symmetrical and i had to slot them a bit...
http://img.photobucket.com/albums/v114/Fraggster/121807_190801.jpg

But after properly clocking the housings and getting the feed and drain vertical, i had another problem with the wastegate bracket hitting the outlet so a few minutes in the bench grinder and we have a bit a clearance but it may need a bit more so i can get a clamp on there as you can see in the third pic with the piece of test hose.

http://img.photobucket.com/albums/v114/Fraggster/121807_195000.jpg

I forgot to take pics of it but i was at an Ace hardware today and they had this flexible metal line very similar to the drain on 2.3t cars. its orginal application is hooking up gas stoves and such. its 2 foot long which is perfect for me and has a standard flare on each end. Also came with some various fittings including a steel flare to 1/2 MPT adapter, perfect for the pan drain! at $18 a kit i couldnt pass it up!

And a couple final pics showing alternator to turbo clearance. not much but theres a good inch or more in there.

small teaser

i have some more parts on the way. right now i have imbarked on a massive rewiring of the front end of the car. removing unused wires completely, some repinning and rewrapping of the dash harness and adding a 6 slot fuse block with its own power feed (on a circuit breaker) triggered by a 30a relay for the wideband, forthcoming guages, rev limiter, hidden shiftlight and fuel pump trigger (fused trigger wire that activates a relay in the trunk for the fuel pump whose feed off the battery (also in the trunk) is fused too. all soldered and shrink wrapped. think im paranoid enough?

also added some junction blocks for stuff like power feeds to the computer and coil and a dedicated ground for the afore mention items connected to the fuse block. I moved the coil to the firewall and mounted the TEMPORARY fmu as i wont have the cash to get the injectors and such till early march.

i hope to have some good pics soon.

[C.J.]

nice, cant wait to see how it turns out

[STOK5OH]

whatr u running for headgaskets? studs?

[STOK5OH]

ohhh...just reread and saw you decided to stay on with the IHI's....lol,should make boost at idle and fall on it's head at 4k. :lol:
My guess is gonna be 350'ish rwhp.

[Johnny]

yeah those turbos are small on 4cyc so you are def gona have some problems... but i guess if you are using a stock 5.0 with stock heads thats about when you run out of power anyways...:lol:
looks like its coming together tho

[Coupelx]

i know of 3 people on TTF.com and corral.net that have made over 400hp on a stock headed 302 with IHIs. should be easily achieved with my gt40 setup. besides its not like its a real big deal to sell these and put on a couple t3's. it could be done in a day. i see no problems with them especially seeing that i only have $150 into the pair of them.

[Johnny]

and I know people with full exhaust that dyno'd less or right at 200 whp when it should have been like 20-30hp more, but that doesnt mean its gona happen for everyone...

either way, At least youre not completly hobgoblining the **** together. Looks like you are doing enough research, I seariously hope to see it out this spring, perhaps I might be able to stay mildly close to your car in a race

[STOK5OH]

uhhh ya...me too.:rolleye2::lol:

[Coupelx]

thanks for the good word.

ive got most of the parts in, just need to get some pics and some work done.

[GTPpower]

Dammit, now I got nothing that's gonna run with you! I think you should remember me....I saw you cruising around a few times last summer, and we raced a few times. I think I raced your 4cyl. once.

When it warms up, I wanna see that thing. It looks amazing!

[Jasen]

I couldn't push my IHI on my SVO past 17 PSI on a 2.3 before it made nothing but heat.

Those would make a great turbo for a 1.5L engine.

I applaud your ingenuity though!

[Coupelx]

that would be me. nice to see you on here.

Well it runs now and far exceeded my expectations. it fired right off and idled like nothing had been changed.
at 1/2 throttle there is no traction even trying to ease into it as soon at its spools the tires are done for at over 50mph and its only at 8psi. drivability is as good as it was before. i cant wait to get some drag radials on this thing and really push it.

I did a little burnout for a friend last week and it had no problems with keeping them spinning in third gear on the AOD and the sound of the turbos was to die for!

IC is a 12x18x3 CX racing piece. Fits pretty good given the small space up front since i am running A/C.

http://img.photobucket.com/albums/v114/Fraggster/021108_230200.jpg

A small video i made
http://img.photobucket.com/albums/v114/Fraggster/th_TT50.jpg (http://smg.photobucket.com/albums/v114/Fraggster/?action=view&current=TT50.flv)

i still need to get exhuast made up for it as i just have the downpipes dumping by the transmission. its really not that loud and i probably will just run some bullet race mufflers. And yes the turbos now have air filters on them but i need to fab up a small curve of pipe to position them down a bit as they rub on the hood. The AC is not on in this pic as i had one of the line redone to go around the passenger side turbo but it all fits and will go back on the car this spring. The intercooler is a bit bigger than the pics show but i had to have one that cleared the a/c condensor and its fan and my bigass transmission cooler. I may put another layer of wrap on the IC pipe where it passes over that turbo but after some spirited driving it doesnt seem to get really warm so we will see. afr is in the low 12's once boost sets in and during light throttle driving it is in the 14's.

[91fox]

Nice job, I have been checking to see if you updated your work log. So hows it run? are you just tunning with and adjustable fuel pressure regulator and the timing?, by a wideband obviously


Im doing a single turbo build on my 91 gt right now,so far I have my battery relocated, I have my Walbro 255 installed in the tank,the oil pan tap/ fitting install is done, just has a plug in it for now, its up on jack stands right now, got all the exhast including the damn headers off just erlier, and I have my kit with all the rest of the parts I need, Im just trying to figure out exactly what im doing to do about tuning for sure when I get everything installed.

[Coupelx]

it runs as well as a cammed 5.0 can. i just have the fmu and adjustible FPR.

Post up some pics of your project.

[DarkSlide]

Those turbos seem tiny for that engine.

[91fox]

what size are your oil drain lines? Im useing size 8 stainles braided hose with all AN fittings

[STOK5OH]

You want your drains to be at least 50% larger than the feeds,IMO.

[91fox]

hey did you remove your front sway bar ?? How much does that effect the driving?

[STOK5OH]

ya you can ditch it,it doesnt affect it enough to worry...the cars already roll from side to side to bad anyway with it and the wieght transfer you'll gain is worth it,especially if you already have some drag suspension under the car.

[Coupelx]

its definately worth it as far as traction and weight transfer goes. if you have good struts its fine with it off, i have a rear swaybar though. i drive mine on the highway with no problems.

[86Shelby]

That's the same car I used to see at SuperSaver on 27th, isn't it?

Looks like fun!

[Johnny]

very nice, congrats on getting it running

[91fox]

yeah post up some more pics and vids of it driving, are you going to dyno it ?

[Coupelx]

That's the same car I used to see at SuperSaver on 27th, isn't it?

Looks like fun!

yea i had a temp job there until my mom had heart failure so it was back to columbus to be with her.

ill get some more vids and stuff when it warms up and i have some more time to tinker with it.

thanks for the compliments, now i just need to get it painted someday :joe:

[STOK5OH]

paint? meh.

[Coupelx]

paint? meh.

pretty much

[Coupelx]

small update. i got some 24lb injectors as even with 50psi pf base fuel pressure and over 130psi of pressure under boost i cant force enough fuel through the 19lb injectors. my TRE pump seems to die off after 110 psi and it leans out to 12.6 under boost. still havent taken it to WOT. i hope to make a video of a run down the street next week after the injectors.

[srt-4_uk]

If you havnt taken it to WOT and you see 12.6 AFR under boost, wouldnt you be rich then. When you are out of WOT, the O2 sensors wanna see 14.7 correct?

[Coupelx]

itbreaks the tires loose at 50mph so i have to go faster than that to go WOT and see what my AFR's are. right now i doing a combination of burnouts and short 3rd gear pulls to look at the afr, lol. i dont run o2 sensors. under cruise and idle the afr looks fine but under boost its not rich enough for my tastes. i have the car back apart for a few small changes right now. should be back together later next week.

[DarkSlide]

What's the AFR under boost?

[Coupelx]

when it starts to spool it drops to 11.3 then climbs to 12.4 under boost just before i let off

[91fox]

I would get bigger 42 lb injectors, then you will not run out of injector with the stock block

[91fox]

what kind of wideband set up are you running ?

[Johnny]

you dont need 42lb injectors, and you need to run O2 sensors, and 12.4 at WOT is not too lean at ALL

[DarkSlide]

you dont need 42lb injectors, and you need to run O2 sensors, and 12.4 at WOT is not too lean at ALL

It's a bit lean for a boosted car.

[STOK5OH]

I see alot of noobs trying to spout random tech. comments/tips here,stfu.

[DarkSlide]

I see alot of noobs trying to spout random tech. comments/tips here,stfu.

Enlighten us o wise one.

[STOK5OH]

you've got more overall experience,why don't you enlighten me?

[DarkSlide]

I have no experience. Just from what I've read, 12.4afr seems a bit lean for a boosted engine when he's not even at WOT. I don't think he needs bigger injectors tho. I think he needs to ditch that shitty fmu and get better engine management.

[STOK5OH]

If it continued to lean out sure,but it could easily get fatter at WOT too. Ya it doesn't need anything over 24's and ya I think a haltech or SCT would be alot more ideal,but I think he's trying to be uber cheap,which means you have to just run what you can...FMU.

[91fox]

I didnt say he would need 42lb ers, thats just what i got because i figure i will rebuild the engine later anyway and run more boost, 24's would do it, just from what ive researched so far wich probably isnt near enough i dont think the stock ones will cut it and doesnt an fmu basically try to make a smaller injector work like a bigger one ? Anyway I just figure with a boosted setup fuel is the last thing to cheap out on. I should probably be quiet because i honestly dont know very much about this stuff but I think what your doing is badass no matter

[STOK5OH]

ya,fuel delivery oversights are bad,mmmmmk.

[Coupelx]

you dont need 42lb injectors, and you need to run O2 sensors, and 12.4 at WOT is not too lean at ALL

my wideband has narrowband simulate, i just need to hook it up.

the fmu will go this summer when i have some extra money again to get injectors and the stuff from moates.net to tune with.

12.4 would be fine but im afraid it will continue to climb. I got the 24lb injectors in tonight and lowered the fuel pressure back down. a stab of the throttle and 3lbs of boost saw low 10's so its a start.

this is a budget build, within reason of course. i have a little under 1k in it. even less out of pocket as i sold off my headers, exhaust, etc.

[Coupelx]

I have no experience. Just from what I've read, 12.4afr seems a bit lean for a boosted engine when he's not even at WOT. I don't think he needs bigger injectors tho. I think he needs to ditch that shitty fmu and get better engine management.

during normal driving it can lean it out 14's with no problems. idling it can be in the 16's. as soon as i see boost i want that ***** in the 11's. or lower. cast pistons are pussy :rofl:

the A9P does amazingly well with no o2 sensors. the afr bounces around a bit but otherwise it stays about where it needs to. when i start tuning it im going to turn the o2 sensors off and just set it to the afr i want it to be.


Edit: i am running an AEM guage type UEGO

[91fox]

under 1 k ! damn i wish i could say the same for my build

post up some more video when you get a chance

[GTPpower]

Looks great man. I'm gonna stop you sometime so I can take a look at this thing.

The 12.4 would be pretty lean on my car. It would be do-able, but I would make lots more power if I richened it to 11.5 and bumped timing a few degrees. I'm sure your car is different though.


Do you know anyone in columbus with a light blue 5.0 that's turbo'd and IC? I saw it sitting in Menards parking lot last friday with the hood off, so I had to stop and take a peek.

[STOK5OH]

that's my cousin Jethro.

your right 12.4 is too lean as far as im concerned. expecially since i dont want to lower the base timing anymore than i have to, it makes it drive like **** out of boost. its at the stock 10* initial right now. i want high 10's to mid 11 afr's.

the blue mustang a buddy of mine. i helped him along with the car. he got bitten by the turbo bug after my 2 2.3t cars.
I should have my car out the weekend of easter. im finishing the exhaust and other stuff right now. look for me in the hyvee parking lot. its one of the few places we havent been chased out of.

[GTPpower]

If I'm around, I'll stop by. I drive an 04 F150 now.

[Coupelx]

still running around on the factory headgaskets!

[ali]

:lost:

[91fox]

cool man how many pounds of boost is the most you have pushed? Im wondering how safe my factory head gaskets are going to be lol, lets see some video man, we should race sometime to see how your tt setup compares to my single, my car is done it is just getting tunned right now

James

[akurtzer57]

sounds like a fun project. Wish my build stayed under the 1k mark. Got up to 2500. I also made all my piping and and didn't use factory turbos....my injectors are measured in cc's. stock were 180cc's (small as ****) now running 370s on first start up my AFR reading of my LM-1 was 6.9! Started to tune a little in drive way so I can take it out and not smoke out cars behind me. Got it to around 9.5 idle and 11.5 at 2k. Then my My quick wiring on piggy back came loose. Lost my rpm signal. But seriously before anything ditch the FMU so you can actually tune the car.

[Coupelx]

the fmu is going as soon as i find a bigger set of injectors that i can afford, i need 85lb's or better since i am running e85 and want some headroom so i dont have to buy bigger injectors right away if i change setups(you didnt hear that).


i am running 8-9 psi of boost. 12* of initial timing. im thinking of trying 14*.

for those interested i pulled 21mpg going to GI and back (130miles or so) on e85!

i would like to turn up the boost but i am running 24lb injectors at almost 50psi base pressure. plus what the fmu adds on top. this TRE 255 hp pump rocks.

i have several sets of low impendance 35lb injectors. i am thinking of getting some resistors and putting them in and turning the base pressure back down. to about 35psi and the boost up to about 12 :)

[91fox]

sounds good man and **** 21 mpg that is cool, you think about putting your car on the dyno or taking it to the track yet?

[STOK5OH]

stock HG's in a sbf,yikes.

[91fox]

mine is all tuned and good to go lets compare twins and single sometime man im running 8lbs of boost also

changed a few things when i placed my order, i switched to a v3.0 board which has the flyback for the injectors built in and doesnt need a separate card.

i am using the TFI module only for the rpm signal and using the MS to fire the coil, giving me control of the dwell and allowing me to use spark cut limiters.

[Johnny]

^some people enjoy the work

[Hibs]

to much work i'd of just got a SCT and been done with it.

seriously.that's just like telling him, "ohh your home built turbo kit was to much work. i woulda just taken it to dyno dan and had him come hire some guy to install a turbo kit on it, as the cost of $9,000"

:rolleye:

[82355]

I agree with Hibs on this one.

Mega Suirt is bad ass by the way.

Martin

[Coupelx]

just now saw this.

i could have used the stock harness but megasquirt is sensitive to old wiring. why deal with 20+ year old wiring.

sure its probably more work than alot of people want to do but im learning and having fun doing it. half the fun is doing it yourself and saying "ya i built it in my garage" rather than saying 'i had so and so do the work.'

what an SCT cost if i were to buy it myself? i have $400 into my MS setup with built in launch control, water injection, hell even traction control and boost control if i were so inclined.


besides i have alot more time than i do money. :lol:


edit:

i been collecting parts. some little things but i did pick up a downs box upper to clean things up and try and kill some low end so i can get it off the line, plus it just looks cool.

been eyeballing injectors. big ones. real big as i plan on going back to e85 for good this spring and dont want to have to buy injectors twice if i switch setups after i break the 302.

[Coupelx]

Back from the dead, eh?

I tore it apart again. I have a list of things i want to fix, change or do different.


pull heads and have a fubar'd valve fixed. i got a little rev happy racing a ls2 gto and now have a random pop out the passenger side.

New TFS valve springs to keep this from happening again.

gasket match everything.

sandblast and hi temp clear everything aluminum

ditch the a/c it sucks as bad as ford's power steering

i have a powerstroke intercooler that i cut down a bit thats going in which means the steel crash bumper is now gone.

sand blast engine bay and weld holes shut.

swap transmissions with one that i bought from 5.0pony on NESS

and finally paint the car. this is the reason we had such a shitty winter, im actually going to paint it something other than flat white.


pics to come tomorrow night

[KyleJ]

Depending on how close you are for space underhood, I'd look for the weld in panels instead of filling every hole. Just a suggestion though.

[Coupelx]

i am looking into that too but i still got alot of welding to do.

[82355]

Keep the A/C.
