Thread: Luke's Blue Turbo Prix

Picked up this Turbo Prix back on October 13th, 2018. Got it from a member on here, Corey, aka (itHurtz). The car is fun as fukk and fast as hell. It's hands down, the fastest car I've ever been in. I wasn't planning on buying a second Grand Prix. But the maroon GTP I spent 2 years rebuilding gave up the ghost at 253,000 miles. So, the Turbo Prix became mine. Passed on from one Grand Prix Junkie to another. With the weather turning nice I'm going to start working on this thing. I wanted to get a thread going to document everything. The car has a list of small things that need attention. It came with new rear struts that need installing, and red powder coated rear calipers that need to go in. Those 2 things will be first. Some pics of my baby blue are below. List of mods includes the following:

Modified clutch stacks (for QUICK shifts) and a trans-go kit for sure. I want to say it also got a bonded separator plate and torlon balls. Can't remember though. Can we get some video of this thing making highway pulls now?

i know i got them torlon balls in my tranny.

yeah get to a damn track and send that thing, being Coreys a pus sy someone has to show us what its got at the track.

homos, he still has to learn dhp and add fuel up top. Or drop the 255 walboro in my porch in, I dont want to be that optimistic on running out of fuel!

tuning 101 classes for all lol

(Raises hand) I want I in on those classes.

It defintely ended up int eh right hands. It will be taken care of for sure. No plans for adding a stall. It's running great and has been under the knife so many times already... I just wanna enjoy it.

I had to look up all that, what you wrote. That's awesome. When talking about the car I always talk about how it was hand built in AZ!!, and freighted back to Chicago. Built by this guy Brandon Hall....blah blah blah. Basically, it's special and custom.

Track time coming soon. Great Lakes Dragway has a free season opener coming up March 29 to April 11. Hoping to make it. Highways pulls coming up too.


and Tuning! Yes. Needs to happen. Gonna have to meet with Corey about that still.




First though, the coldside intercooler pipe, going to the turbo tore at the box. I was inspecting fog light wiring and noticed the crack. This needs to get welded before any pulls.

damn that sure did split.

LOL!

Jesus, cheatah! LOL. Got your mind in the gutter, huh?

Alright. The inter-cooler is off. One of the mounting tabs was broken, and I sheared off two more to get it off. Should be a an easy fix for the welding shop. Toughest part really was the couplers. Ended up just cutting them. You can see them in the top left corner of the first photo. Also had a clamp bolt round off on me. Used a disk to slice through the strap. Now I need a new clamp and 2 new couplers.

Oh ya, the couplings you should have put a screw driver inbetween to break the seal, and the clamp bolts were 10mm and 11mm mixed up (not my doing)

I hope the welder makes those tabs more stout, cartuning didnt think decades of use imo.

The IC is with the welder now. Had my wife drop it off so I created a card-board mock up of how I want the tabs to look. I numbered the spots so that when I called we would be on the same page when I explained how I wanted things done. The radiator support is a little rotted and shouldn't be holding up any of the IC's weight. The original side mounting tabs on this IC were up against some of that rusted metal, so the side tabs are useless now. The metal bumper is in pretty good shape and it will be holding the full weight of the IC. I added a bracket down the middle of the IC to have a third mounting tab. And then 2 tabs/arms on the bottom to connect to the rad support, but only for stability, and not bearing any weight. Then the pipe that split needs to be fixed. That split really started this entire project. They will cut into that chimney are redo that entire exit hole and weld in fresh pipe.


Cost will be approx. $200 for this work.


First wad of cash. For this car. Has been dropped! haha



I snapped this ugly photo of the cardboard mock-up in the morning before running to work.

support rusted what!!!

Wads of cash happen

Work gettin done over here! Over the last few days I got to work on installing the MOOG strut assemblies, and rear calipers. As it turns out, the powdered calipers were for a '05+ Jeep, not a Grand Prix. This messed things up and slowed me down. I was set on replacing them so I drove to Phoenix Caliper company, traded in the powder coated rears, and GP cores, plus some cash for new rear calipers, clips, and ceramic pads. Everything went smooth until I got to the drivers side, top splined bolt. WOULD NOT COME OUT. Pounded it. Torched it. Tried pushing it out with a C-clamp. C-clamp snapped. 24hrs. later the car gods took pity on me and let the bolt loose. ****. Insane amount of energy went into getting that 1 bolt out. Picked up the inter-cooler too. Mounts looks beefy. Test fitted new couplers. Also new clamps. Pics below.


REAR BRAKES
Sanded rear hats
Painted with POR-15
Remaned Calipers from Phoenix
Painted with POR-15


REAR STRUTS
Replaced with new MOOGs


INTER-COOLER
2" Exit Pipe welded in
Chimney that leads to pipe widened .75"
Chimney also sealed with new welds
Top right corner of IC also sealed with new welds
5 New Mounting Tabs
New couplers (4-ply ; 4inch)
New clamps

thats one BFH you got there. maybe to big for w body repairs lol

how the hell yo break the c clamp? them strut bolts, i just hammer the fuk out of them till they come out, baby 5 lb sledge works great.

welder looks to have done some nice work there.
