Well i decided I would toss my build up on here seeing all the 3rd gen builds popping up. Maybe it will help others on theirs. I also didnt want to drag on a full build on here, wanted to wait til it was somewhat complete.

I bought a low mile stock LG4 305 auto car 2 summers ago after getting bored with my FRC vette. I wanted to build another 3rd gen (last being a 370 LS single T6 turbo) but wanted it more street friendly with a goal of around 550whp, so it made sense to do a 5.3L build this time around.

The first summer I had the car I worked on suspension, then built a 3.5" exhaust all the way back since I knew I was going turbo.

So far the car is out on 6psi and seems to be running great. Usually its steady 170* temps, 50psi hot idle oil pressure etc. I have surprised a few people for a stock motor on 6psi how good it moves.

It shocked a few people at the last local car show I went to. Lots of older guys pretty interested in the setup.

How can you go wrong with a white turbo LS 3rd gen!?!?! LOL Good work. Clean build!

Thanks! I actually searched for like 4 months to find a clean white hardtop. My wife hates that I didnt get a T-top again but its not her car (even though she disagree's LOL)

I love this! I want to do a turbo 5.3 on my 91 rs. How much power are getting out of it? How much did the build cost?

jay_rich

iTrader: (8)

havnt dyno'd it yet. only about 150km on the setup so far. I would say on 6psi its pretty comparable to my old 383lt1 na setup which made 411whp.
I havnt added it up but i would say around $7,000 for everything (trans, converter, motor, turbo stuff, fuel etc)

Jay

That's not bad. Where did you get the turbo from? Did you purchase it as a kit? Do you still have ac in the car?

That's a good management of funds at only 7k for all that. Not bad at all.

I bought the turbo from DNS on ebay. Most common on theturboforums. I built the entire setup myself. The wastegates, bov and injectors i waited for black friday and got a smoking deal on them.

Pretty well the entire build I waited for deals to pop up when i was driving the car with the gutlass 305. Being my 4th time buying LS parts I knew where to shop lol.

Are you still running your ac?

jay_rich

iTrader: (8)

No AC was deleted. I went with c5 accessories and didnt know the compressor wouldnt fit so canned the AC.

Cool project-what are you using to control the engine, was the dash more of a plug and play deal

I am using EFI live with a 99 LS1 PCM and I reflashed it for 2002 Operating system on a 3 bar map. I built the harness from scratch using a truck harness, then repinned the trans for the 4l80e. I flashed in a 2002 4l80e segment into my tune. So far so good. Shifts great. Very simple swap.


The Dash I built myself. The Maxigauge (center display) uses an external box much like dakota digital. So I ran an seperate sensor harness for that, then I was left with the Tach, fuel pressure, volts and fuel level. (fuel level, signals and highbeams I tapped into the stock cluster harness)

The Speedo is a GPS unit which makes life easier.

What would I need to do a similar build on my 91 rs and keep ac? Is it possible? I'm very new to this so I apologize for all the questions. I'm learning a lot here though and really appreciate the input.
