Drive around the water box if you are on street tires, pull up to the staging beems. The 2 lights on the top of the "Tree" will light up, then roll just a little bit more forward. Hold 1 foot on the brake and push the gas pedal and build up some boost. If ya want to get a good reaction time left off the brake on the 3rd yellow light and hit the gas. Ya just want to work on launching the car ya can sit there as long as ya want. It wont change the time.

Crappy vid but Ya should be able to get the point.

I'll buy the whole turbo setup if ya still got it.

Shoot I'd buy it just for the trans and all that to swap into my 96 if I had the money. Good find.

Well I ended up cutting the tube and making it half metal and added rubber hose and re routed it till I can find or have a replacement made.

Well I finally found it and got it off. It was a metal coolant line down by the exhaust and goes back up turns into rubber and then goes into the heater core. It had a good rust hole in it. Man is this car hard to work on. Everything is just jammed in and some weird stuff. I mean Ive worked on 3100's which its hard to get to the back but do able and 3800 well is a piece of cake next to both of these.

Anyway back to the problem. After I got it out I went and check the parts stores and of course they didn't have it. So I went to the dealer and spent 30 min trying to explain to the guy what I needed. We found it but GM no longer makes it and no dealer had it in stock. So he had to call a vintage GM parts store which had it but cost me 70$ for the 2 lines and hose. O well at least I found one. Should be getting it later next week. Then I can get this thing on the road a little before winter.

The paint looks good, better than mine on the bumpers. Take more pictures of the engine and the interior.

Lots of K&N filters will fit, there's a sticky in the Performance forum. (I have a RU-1390 but I don't recommend it because the engine torquing over is pretty much guaranteed to crush it.) Some people also run some exhaust pipe from the turbo down under the car and pop the filter on near the bottom to get fresh air in. For a tune, PM flybynite, I just got mine re-tuned by him literally a couple days ago, waiting for it to ship back.

The paint is pretty good and should shine up pretty decent. Only part I don't see coming out great is the trunk since it at pitted. I plan on restoring to 100% original and then get it repainted in a year or so.

I bought the one K&N 5" filter with the 20* bend. I am just put on for when I drive it. But When I take it to car shows and stuff I will put it back to stock.

Ill get some pictures for ya tomorrow.

Nice TGP bud as far as the coolant leak check the coolant lines that run on on the firewall and the one that comes off the back of the intake and runs under the down pipe and back up. That pipe on my TGP rubbed a hole about a year ago.

That sounds a lot like where my leak. I can see It leaking on to the down pipe.

I have a decent coolant leak on the rear side of the engine. I can hear the pressure of the leak after I turn the car off. It goes through pretty fast. I had to drive 150 miles home and had to stop every 15-25 miles to add water.

Any idea what it is. I've looked at all the hoses going to the heater core and none of them look like they are bad.

I was going to turbo my 96 GP but it ended up having very bad rust on the driver side trailing arm mount area. So the search started for a TGP on craigslist. I found about 4 for sale with in 4hr's driving distance. Ranging from 1400$-3500$. Only 1 had pictures and sounded to be a perfect car for me to restore and was only two and half hours away. It was listed for 1500$. And I got it for 1200$.

Its a 1990 with 121k miles. 1 owner and hasn't been on the road really since 2000. 100% original. Even has the factory gm floor mats. Interior is mint - the sagging headliner. Exterior is decent. No rust except a little spot on the conner of the roof where some paint came off. No rust under the car. Car runs good. Only issue is a big coolant leak somewhere on the back side of the motor.

My plan for the car are to restore it to original. Only things I am thinking of doing is maybe a K&N cone air filter which I will run when I drive it and put stock tube back on the air box when I go to car shows. I think I want to take the cat off since its a little too quite. And a chip for it if I can still get one.

Here's the pictures of how I bought it
