This car is my first. My now wife and I bought it back in 2011, many cars and trucks have come and gone, but it’s been my pride and joy ever since. The old engine made it over 300k miles with only maintenance!
I picked up the t56 from a garage sale for $500... and in the nature of all car projects everything sat for about 3 years until funds were aquired...
but when they were,
And now finally, after years, it was time to assemble... but quickly because fort hoods HOAs are horrible, the following pics happened in the course of 3 days...
The culmination... ...Of years... ...Of hard work... ...And my very understanding bank (wife)....
Preparing the ls1 engine harness... (shoutout to pocket for all those awesome write ups..) This is the engine bay stripped down to basic powers and grounds harness.. Laying and routing every.. single.. wire..
the only issue I had with the harness, was that I mixed the two wires for the coolant temp sensor. It was reading like -90* lol... I’ll be honest it took me quite a while to figure that one out... but after I did...
It runs pretty decent as of now and I learned so much doing this swap .. I have tons of random pics and a few extras on my YouTube page... I would like this to be inspiration for anybody that wants to do this but doesn't think they can... It took me quite a few years, but I did it, my wife helped me along the way and we grew a little closer because of this car....
Awesome. Did you do anything to the engine or just rebuilt with stock parts? What headers are those?
its a stock bore aluminum LS1, forged coated pistons (STD bore) clevite bearings, ARP mains, caps, headbolts. Heads are hand ported 243s with a comp cams XR275HR-12 bumpstick. I wanted it to spin really, really fast Headers are the stainless 1 7/8 inch speed engineering headers. They have 3 in collectors and the fit and finish of these is out of the park for the $300 shipped I got them for. They blue quite a bit, but they are headers so I don’t mind. It’s supposed to be fast, not look pretty lol
She’s a lil rowdy...
Forgot to mention I picked up a set of these bad boys a few months back off facebook for $250, I’m going to have them restored and mount some 225/55r15s on them.
I may have missed it,what kind of exhaust do you have?
its a set of speed engineering 1 7/8 primary headers with 3 inch collectors, from there it’s a custom 3inch y pipe (a lot like the hawks one) and then 3 inch straight to the quad corvette tips you see in the back. No cats, no resonators.

Nice, I have the same headers waiting to go in my car.
Ill be honest, I’m so happy with them, I’m not even mad that I couldn’t find the 20% off coupon lol
I actually installed these headers with the engine and trans bolted in the car as well... then installed the starter after that!
Nice, that will be helpful information for me when I go putting things together.
ebay has been having quite a few 15% off days lately, haven't seen the 20% since that time but that's still a nice discount and I've used it on several other parts.

interesting... hopefully this promo is still going when I get back to the states... I need a posi diff and a few other misc parts. As of now I’m still running the v6 open rear and all 4 coil springs are sacked out... it’s all nickel and diming from here. I may do an LSA supercharger swap later on.

It's a pretty restricted time period, like less than a day. You have to use the discount code within that window. I'll shoot you a pm if I see it come up again. Usually happens once every other month or so.

unfortunately, I’ve still got about 4 months left in my rotation, so itll be about 5.5 months before I can get moving on her again, until then she sits in storage 😞
Doing a very similar swap outside Detroit. 91 V6 RS . Pulled T56/LS1 from 04 GTO. Ported 243 heads/cam from Thompson Motorsports, with 590" lift cam on single springs. Found a 9 bolt posi with 3.70 rear swapped in and cones appear intact !

Just pulled the 3.1L this weekend...
Thanks for serving, and stay safe.
Thanks for your support,
The GTO Powertrain is such a good find, I wanted one for the front drive but they are so expensive... I’m still trying to decide what I Want to do with the rear end, I could swap in a 4th gen rear but I’ll loose tire width. I think I’ll just go with a drop in posi. My stock 3:23s are such great highway gears... It does 80 mph at about 1600 rpm lol..
