Okay guys, I'll be updating this thread in the coming days/weeks, but basically we're building a '92 Pontiac F-Body in which originally came equipped with a 3.1 automatic (manual pending, if unable to get the stall that we need). We just now received the GT66 turbo charger through UPS, and was initially waiting for this very thing before we began embellishing on this journey. Why, "journey", you ask (smile), well, let's just say that twelves has already been done, and elevens, well, is kinda boring.....
I'll be posting pictures of the process so far later on tonight. Noah, I didn't forget about you buddy, the pictures will also include Dave's STB as well. Just recently finished installing both a vacuum/psi gauge, along with an AFR gauge (carbon fiber units), and Grant GT steering wheel. Ram Air 1 hood was also just added, with the notchback being installed either later on today, or tomorrow. ECM control is still up in the air, but that's later on. All engine work will be greatly detailed as well, absolutely no secrets.....
was wondering when u were gonna finally post up the project.
but anyways this car will be the fastest turbo 3.1 f-body to date.This car will have many advantages over what mine did and will be sure to turn heads everywere.
Just to give you an idea of what we are originally working with, here is a pic of the car in it's bone stock form. Nothing has been added or removed since it's release in late '91 (save for the mileage). Bone stock 3.1 automatic, T-Tops and A/C.....
Here are a few more pics with some recent additions such as; a Ram Air One Hood, 16" Formula Rims w/255's out back, and 225's up front, Kenwood CD system, Grant "GT" steering wheel and dual gauge pod w/AutoMeter Boost/Vacuum & AFR gauges.....
Should look pretty cool when you are done with it. If my car wasn't a formula, I would get an aftermarket hood, and blackouts and get a custom paint. But, I want to leave my car the way it is as a sleeper. If I do repaint it, I will get it painted the same with the same decals and everything.

The pictures above are captions from Streetfire.net. I had no other way to pull pics from one of my DVD's, so I had Streetfire host the very small video's for me, then pulled a caption to link for you guys here. The video's are only seconds long, but if you would like to check them out before I start posting larger pics, I'll provide ya's with some links.
What is the ETA? Are you going to be able to get some runs in this season?
... all that's left is some tube routing, and the ECM. Believe it or not I'm still undecided w/the MegaSquirt (although I'm now leaning toward it even more). Just waiting on a few more pieces to get here, and the car should be finished very soon. Don't worry, I didn't start this thread to have the project lasting all the way through next summer lol. Will be making some preliminary runs first w/out the turbo, then shortly after that, w/the turbo. About a week or two, give or take.
Give you props, but you have an unfair advantage over me. YOU HAVE DAVE HELPING!!!
Just wanted to point something out in case people didn't know. My cousin Gaspar uses my User ID pretty frequently to post on ThirdGen.org, among others. This is why you'll see from time to time my name changing from "Rob" (me), to Gaspar (him)....
I personally need to give props to my cousin Gaspar the tech guru, who's been modifying GM cars for years. Dave is pretty much building the custom turbo system for me, as well as the head work, UIM and LIM. Both guys are helping me out tremendously w/making Project BTA happen....
LOL, we took it off when we installed the RA1 hood, didn't want it to damage it (the hood) just in case it initially didn't clear. I'm actually away from home at the moment, but I'll see if my cousin can get a quick picture of it online for ya. If I can't get ahold of him, both Dave and I are going racing later on this afternoon, and I'll have one up for ya shortly once I get back....
3.1/hybrid/3400 all the same this thing will be badass
Absolutely.
Also, what people don't realize just yet is the tremendous amount of weight being eliminated from the vehicle. In terms of power-to-weight, cubic inch displacment soon becomes irrelevant when running a turbo. Yes, you'll make more power on the dynojet with more cubic inch displacement, but 9 or 10 seconds in the quarter mile is still 9 or 10 seconds in the quarter, either way you slice it.....
Did you ever actually get a hybrid in your car, dave?
in no particular order
#1 expected weight of robs car is to be approx 1,200 pounds lighter then mine
#2 i made alot of compromises with my car on everything from tunning to suspension due to the fact i had to drive this car everyday.from what ive gone over with rob there wont be any compromises on anything
#3 this thing will be tuned the right way by way of ecm tuning
#4 robs turbo is suited more to all out hp/drag were mine was a street/strip setup,his is also capable of approx 725 hp =/-
#5 i learned form my mistakes on my setup which will be greatly improved apon with robs mainly the foward facing headers
Here's a better shot of the wheels that I decided to go with. Coming from a stock '91 Formula, these 16" rims will do extremely well. Again, 255 out back, and 225 up front. However, in the coming weeks, 275's will definitely need to find their way on there very very soon. Also provided a close up of the carbon fiber Auto-Meter gauges that I went with.....
btw guys if u look at that pic u will see that u do not need an idler pulley to remove the ac,u can remove the bracket and compressor and just run a shorter belt.u can do the same with the idler/smog pump as well

manual pending, if unable to get the stall that we need....
Well it's been solidified, we're going 4000 stall. Here's a pic of the 5-speed that may just find it's way onto the project later on, but for this particular season, no damn lag allowed....
My guage pod looks exactly like that except my boost it on top.

I've been trying to tell people that all along, you would have to reverse the wrap on the waterpump/crank to get rid of the smog.
Man seeing that A/C gone makes lots of room for some turbo headers. If I didn't live in FL, I would ditch the A/C in a heartbeat (it's 1.5hrs to the track each way )
Last pic for the night, something that every 3.1 turbo builder needs to have. It's mandatory!!!! A "Precision Turbo" banner in their home garage. Yup, it's fun for the whole entire family. Yeah, and even the wife enjoys it, too.....
Before anyone asks, that's my spare 3.1 w/5-speed....
offhand i donno just yet, i need to check inventory at work to see if i have the materials/hiem joints in stock,if not ive got to get a price quote on said materials before i can give anyone a price
dam rob i figured u would have updated this by the time i got back home lmao
Looks like I'v got to get cracking again. One more bedroom to re-do the flooring in and...
Well anyway, I wish I had some "gearhead" friends that weren't miles away on the internet to work on stuff with me . Can't wait to see what you are doing with this project!
The crank I just got delivered is shot... Click Here
^ That Porsche was bad@ss! Had that of been their first run, that video would have shown us right by the burn out box. During that run though, we were in the stands. Hope that dude comes back soon, as we'll give him a little comp, that's for sure....
u have it backwards
