Turbo GTA Project...Update #3...IT'S DONE!!
We are finished save a few minor things to work out! My red GTA now has a TTA 3.8 V6 and it runs GREAT! We cranked it for the first time last night and it started right up very easily. Ran it for about 20min. till it warmed up. Hooked the OTC 4000 up to the ALDL and scaned it for codes...none. Everything seems to check out okay. The real test will be tomorrow when we test drive it for the first time. If all goes as planned this thing should be a very bad a$$ car!

What made you decide to put a 3.8 turbo in your car instead of say..... putting a turbo or a supercharger on a 350? Im not bashing you. I want to do something along the line of one of these 3 and just wanna know your reasoning. Congratulations

Gigolo: Get Blown? said it. It will make tons of power, and like Mike said it will go 12's if you touch it right! I was going to have to rebuild the 350TPI I had because it was way down on power; ran 16.20's and had a 140K miles. That would have cost some money and then adding a supercharger would have been even more cash. A turbo 350 was pretty much out of the question because it would have to be a custom fabricated setup. I swapped in the 3.8 for less money, it will make more power (disclaimer: 'In my opinion'...don't want to start another fight), and will go faster. This engine is stock except for forged pistons; stock cam, heads, turbo, intercooler, chip, etc... and I'm hoping for mid-13's which should be a realistic goal I think. That's pretty much why I did it. BTW it's so much easier to work on than the 350 was and it gets better gas mileage.

Would it be even faster than a 350tpi with aftermarket heads, cam, vortech supercharger and a 6speed? This was what i was leaning towards. Gas mileage is not an issue. I only live 7miles from work

Congrats, even though those 3.8 turbos move, i still like my V-8's. you will be able to go low 12s pretty easy. I wanna one day try to do that with 3.8-or 4.3 without a turbo.

Steve: I've got pictures of the whole thing from beginning to end. As soon as I get them developed I'll scan and post them.
Mike(TTA): The mid-13's estimate is high, but I don't want to be disappointed. And yes to start I'm using the stock chip. I'm running closer to 9.0:1 compression with the TRW forged pistons; lower boost levels and more conservative timing will hopefully keep me from knocking. This is just to test this combination out so I don't go right out and blow a head gasket first thing. Then maybe a mild street chip or custom chip is in order.
TomP: I got the engine from a friend who's owned a few TTA's and had a couple extra engines. I got really lucky basically.
Grandnat: You coming over tomorrow night?

Its going to run like sheeet with the stock chip. I understand your thinking but in my opinion your wrong. Its Possible to pickup 50-60hp from a chip in these cars. Yep, You read that correctly.
The Stock Chip is a POS to start with, its setup to make 16.5psi with the factory settings which is fine for the street but its setup for an 8:1 motor. Your motor is 9:1 not 8:1 your going to be running into problems and have more of a chance of detination.
IF I were you, I would call Joe Lubrant at PTE and tell him that you have 9:1 compression and you need him to cut you a chip. I have no idea how much boost your going to be able to run with 9:1, maybe 14-15psi on pumpgas I would think. Thats just my guess outa the air.
Be Careful.....

And you can use a GNX aftermarket chip in a TTA. It will control the Buick motor perfectly and yes even your 700-r4. Or at least I think that's correct...I haven't looked into Buick turbo motors in some time.

The GNX, GN and Turbo T/As all use the same ECM but have different programs in there stock chips. You can interchange them if you want to, but they all still suck.
You spent all this money doing the swap, call PTE and spend another 50 bucks on a chip so you can actually enjoy the ride that you just built.
Last wednesday night this guy showed up at the track with a Bone Stock 87 T-type. He was running low 14s at 99mph. The traction was horrible so the ET's for everyone sucked.
Anyways, He took out the Stock Chip and Put in a Modern Muscle RaceChip and I found a piece of wire in my truck that I gave to him to "Short" the Terminals in the ALDL to lock up the convertor as its going down the track. First Pass with the same boost levels the car went 13.87@105mph...
Forget about the ET, look at the MPH. 6mph from a chip and a piece of wire. 105 is good enough for 12s with traction...
These cars are BIG time computer dependant. The chips make or break you. Ok, I am done preaching its your car. Hope Your out having fun with it!!

Mike, you took the words right out of my mouth! Dan Nevin is the guy that really helped me with this swap. Dan, Grandnat, and I all agreed that I am going to call Joe Lubrant up ASAP and get a custom chip for this setup. The car definitely likes the stock TTA chip better than any aftermarket chip Dan has (he's got tons of them...from ATR to Conley to Thrasher). With the stock chip the car runs a max boost of 14psi (I don't know why, ideas?) and a pretty rich mixture. It does have a tendency to detonate still, possibly still too much timing? I'll give Joe a call on Monday and see what he recommends?
Okay, now how does it run??? Even in this current state, out of tune, it still pulls...HARD. I raced Dan's TTA (TA-49 turbo, chip, K&N, downpipe), it's run a best of 12.9 @ 110mph. We ran from a dead stop. He pulled 2-3 cars on me at the launch but once I got moving he stopped pulling and I actually started to creep up on him to about 80mph. On the highway we were pretty close, I was on his rear bumper and actually started to pull on him slightly from a 55 roll...we have neat tail lights BTW!
This car is going to be a fast car once we get it tuned correctly. Not bad for about $2000 ($3000 for the car!)!

Do you have an adjustable wastegate rod? Screw it in 2 turns (Shorten the Rod) and that should bring you up to 16psi. Just check it out on a scantool to see whats going on....

OK I see why you did the swap now...$2000 is a killer deal! Congrats.
What all did you have to do to make the wiring harness work with the turbo V6?
Or did you have to get a whole new harness?
Can't wait to run ya.
A bunch of us are going down to Ennis next weekend. If all goes well, come down with us.
See ya

Hey Brendan the stock chips are high in timing..and that causes Detonation.....especially on a 9 to 1 motor with 14 psi of boost. I did some checking and I found out that on a 9 to 1 compression motor it is very similar to increasing boost 3-4 psi....in other words on a 8:1 motor if you run 18 psi on 93 octane and are getting a little knock......with a 9:1 motor you could only get away with 13-14psi....so actually you are right where you want to be..and that explains the knock..BTW we talked about this last night but I didn't have all the facts..but it turned out that is the case after I did a little on line checking.
BTW the only reason the TTA was pulling you from the start is because he has a 2200 stall converter stock....your 1800 converter is not mad for a turbo car and thus does a really bad job of spooling the turbo.
get the small stuff taken care of and that thing will rock.
we still need to figure out the rich problem....I have a bad feeling it is the MAF...but get an adjustable FP regulator and turn it down 2-3 psi and see if it clears up.
talk to you later...BTW I am free wed if you want to hook up Tlink and do some more tweaking.

I may consider a tech article on this swap but then it wouldn't be a secret! Actually everything (at least the big things) you need to know is covered in the FAQ section on this site. But just to convince those of you thinking about an engine swap THIS THING IS BAD A$$!
I'd love to take this car to the track right away and see what it runs. However, there are a few tuning issues that have to be sorted out before that happens. In fact, with this car running right it will be faster than it is now and I'm sure I'll be happier with the results.
Grandnat: I'm off tomorrow but I have to work Wed. 4-10p. I have been taking it easy on the car today. I borrowed the OTC 4000 from work (same as Dan's) and are trying to keep tabs on a few things. It's running hot, at least compared to Dan's TTA, around 200*. Lowering that temp. might help to lessen detonation. Maybe I should start buying gas somewhere else? I'd be happier with 0* knock retard. Right know I'm seeing about 7-8* knock retard. 1st gear I get 0* knock. I noticed one thing last night, though, the boost isn't pulled down to lower levels in 2nd and 3rd gear like the aftermarket chips do. Besides the rich mixture problem do you think that a custom chip will solve a few problems? I can order a few MAF's in and we can see which is the best. Should the MAF be maxed out to 255 with stock boost levels? What was my O2 voltage last night at WOT? I'm going to call Steve Kaminski tomorrow and see what he says since he's familiar with this setup. In the meantime I'll take it easy.
BTW I'm planning on getting a stock Corvette torque converter; they stall around 2200-2400rpms and they are reasonable priced from what I hear.

Hey Brendan,
In the pic on your website are you parked out front of O'Reilys?
Im pretty sure that i just saw your car today when i went to get some stuff. Ive seen it there before, but have never seen the gold TURBO emblem on it.
Looks real nice. Ive seen you drive by the Sonic on Custer before. I work at the Express Lube right there.
What area of Plano are you in?

Car: 88 GTA
Engine: 350, 383
Transmission: T-56 & 700R4
Brendan,
You kept the 700R4?
I thought the Pontiac (BOP) block has a different bellhousing bolt pattern. Did you have mod the trans? or use an adaptor?

The 231 block does use a BOP bolt pattern. I bought a TCI trans adapter (pn# 230001) and it bolted right up pretty easily.
Works great with the 700. I still have the stock torque converter which seems to be stalling at 1600rpm and is not going to cut it. I can't build any boost pressure at the line without spinning my tires. The original TTA's came with a 2200-2400 stall I believe similar to the 'Vette.
Ratnose: What Express Lube is that? Is there one at Custer and 15th? I know of the one at Coit and Parker. You guys do inspection?

My topic is on fire! 
Yeah I'll stop by some time when I'm in the area. I've got a friend that works at the AutoZone across the street; he drives the light green '65 Mustang. Speaking of...why are you shopping at AutoZone?!?! Most of their parts are junk and those guys are sometimes lacking in the 'know-how' department. Do you guys have any 'corupt' inspectors? I need to get my car inspected. I'm only missing a closed air box; I've got a cat, etc....
