Thread: Moozery's Comp G

Hopefully next weekend I'll be the owner of this 04 Comp G (100,000km)
Which would be replacing my rusty old 04 GT (260,000km)

Comp G:








GT:

Pictures with all that white sh*t give me the chills!
Not the car...the white sh*t covering the car!

From 2004 -2008 your only choice was a Grand Prix with 2 extra doors because the GTO came only as a 2 door.

Well it's been 6 months, and the old snowball is still running decent. Still fighting the misfire and some other KR and LTFT issues, although getting it more narrowed down and improved as I tinker with it. Now that a lot of tuning-up has been done I've been working more towards actual upgrades.

Some photo's I've taken so far:

Did the LIM shortly after getting vehicle


Previous owner had a pet in the intake


Red calipers, cause red stops better ofcourse


Had a hitch hiker hiding under my wipers


First real upgrade - ZZP 3" Downpipe


Seafoam


Everything done so far:
- All fluid/filter changes, wires, seafoam, TB clean, MAF clean, etc
- LIM gaskets
- Denso O2 sensors
- New injectors
- TransGo Shift Kit
- AL104's gapped to .050
- Spectre open cone
- Dexron VI pan drop
- ZZP Catted 3" Downpipe
- Intense PCM
- Aeroforce Interceptor gauge
- Cardone driver side CV axle - already clunking again

To do:
- Wheel bearing
- 06 Impala brakes
- Front strut brace
- Flipped dog bones
- Replace vacuum lines
- Considering front Plog and/or 1.9 rockers

coming along nicely. surprised the LIM gasket change didn't fix the misfire as sometimes a leaky/bad LIM gasket would cause the misfire due to coolant getting burnt off.

Yeah I was really hoping it would've fixed it, but it didn't make a difference. Big improvements in other areas though.

I actually just very recently went to the 104's from NGK TR55IX's. I was aware it was too cold at the time but it was a recommendation from John at INTENSE performance when I got my tune and told him the amount of KR I was having. The misfire however, has been around since the day I picked the car up when it (seemingly) had factory spark plugs. Back then, it was bad enough to set off a check engine light anytime you idled for more than a minute or two.

I would switch back to my TR55IX plugs, but one broke during the swap, and I've found a bit of a performance improvement out of the copper 104's. Maybe I'll give 605's a try though, at a buck a piece it doesn't hurt to experiment.

I'm from Grey County, couple hours NW of Toronto yourself?

I'm about 45 mins SW of London on the 402,been around the grey county area quite a bit though as I had relatives that just moved from Owen Sound back down this way not to long ago. Nice clean looking GTP you got there, I don't see many white comp g cars.

Ordered a set last night on rockauto, needed some vacuum hose and wipers anyway.

Oh yeah not too far away then, im just 30 minutes from Owen Sound. Drove all the way from here to Ajax to get the car an hour or two after it was listed on Kijiji.

Thanks, yeah the body is in amazing shape except for small rust specs in typical spots, getting a quote from a body worker soon if i get around to it, as well as a good undercoat. Starting to realize how high maintenance having a white car is though haha, shows dirt real well.

Been doing a little exterior mods:



Not sure why I had the genius idea of dipping the Pontiac emblem rather than just painting it, definitely going to retry with paint at some point. Still better than the ugly pink that it faded to.

The red GTP lettering was done by pulling the "GT" letters, as well as the "P" out of the Grand Prix lettering off my old car.

Polished the old exhaust tips as well, pretty surprising how much of a difference it made. Old ones were almost black.

Just finished this, gonna give this one a shot tomorrow:

My current "winter" project:
