Hello all!
I recently purchased an 06 G6 GT coupe, as it was the only car that I could find that really was a blast to drive. (More fun than the Solstice even!) I've driven a 99 VW Passat 1.8t, and an Audi TT VR6 in the past. I've been a regular on Audiworld, Passatworld, and VWVORTEX for a few years. I've left all those boards - and I will hopefully become an active member on here, albeit - I have a lot to learn.

Anyways, about my new car. An 06, 30k miles, G6 GT, heated leather, remote start, monsoon, 17s, I think it has every feature available. It's more fun to drive than even the TT - though I do miss my turbo upgrade on the VW..
^ Which leads me to questions for you all!

1) What kinda coolant does the 3.5L V6 GM motor require? Dex-cool?
2) Besides CRAB Intakes, and ECU tuning(is that what it's called on non-Euro cars?), what mods are there to increase horsepower? If a turbo was purchased, and the engine was tuned correctly - would the transmission hold?...
3) As you can tell, I know nothing about GM or Pontiac, or ANY domestic cars. I can tear apart any VAG product though! Any advice on maintence/mods/ANYTHING is GREATLY appreciated!

Hopefully, I'll learn a lot & be an active and helpful member.

P.S - VWvortex is known for immature kids, that LOVE to start internet arguments about idiotic things. I'm not one of them, so please don't judge me :) I've only had the Pontiac for a week, but I prefer it over the Audi/VW brands! And I can't believe how this motor doesn't require 0w40 fully synthetic oil every 3k, or 93 octane gas, or 800-1200 dollar timing belt jobs.. It's amazing! Shoulda been buying domestic for years!

OH - and if anyone wants to buy a 99 Passat AEB 1.8t with stageone turbo upgrade(k04), Einbach coilovers, tint, two alpine type R 12s w/ alpine M1000(1000w mono rhythm), 20 inch BBS w/ pirellis.. Just let me know. It's all for sale as a package, or individually.

Cheers!

You got a problem wit dat :bandit:?



Welcome and interesting perspective you have!



As for G6 mods, turbos have been tried but all have ultimately failed so far. In addition to CRABs and WAMS tune, the GT-R exhaust is highly recommended :D

Oh yeah and for coolant they say to use Dex-Crap but I switched out to Zerex something-or-other (will have to check when I get home) on my Grand Prix after an issue at about 50,000 miles.

Oh, come on. You know VWVORTEX is filled with the internet versions of Charlie Sheen! Thanks for the advice, the intake is taken care of. I will be looking into the WAMS tune, as well as the GT-R exhaust system.

Is there any other suggested modifications?

Thanks for the warm welcome, by the way! Much appreciated.

Thanks!

& It turns out, modding the car will void my Warranty.. So, I'm not going to be doing anything to it for awhile. :\

the law is that it can only void a warranty if the aftermarket part lead to the failure of the part your trying to get warantied. if that makes any sense.
get the CAI and if the car need to go to the dealer just throw on your stock intake. and WAMS offers invisitune so the dealer wont know your tuned. and for a catback exhaust the only warranty it can void would be the stock exhaust, but that wont be there anymore.

Welcome to the group! One good thing about our cars, the only thing that 'might' become questionable is the intake - which as another member said just keep the old box and worse case pull it out and install the old one. Motor mount inserts, strut tower bar and maybe some lighter weight rims - thats about all we can do so far haha!

can't wait to see/hear about your future mods!

Thanks for the warm welcome.

I've figured out my plan for the G6 thus far.

1) Tint on Tuesday @ 1PM. Deciding on 20%, 35% or straight 5%. - All are illegal here, so it doesn't matter anyways. I know the penalties.
2) Meeting up with Hybrid Dynamics (www.hybridynamics.com) & they suggested via phone - cold air intake WITH a velocity tube, custom made exhaust (CAN ANYONE EXPLAIN THE DESIGN OF THE STOCK EXHAUST ON THE G6 GT? It has like 360% of 100% useless restriction) and following this up with a complete dyno-tune.
^ The dyno tune will cost 450, but it will be specifically to my mods & car itself. Is it worth the extra 150 to see my car dyno'd properly and tuned to my liking IN FRONT OF ME(vs WAMS typical reflash) The garage has NO problem with explaining what they're doing, and why to me. They've taught me a lot.

I only ask because - I had my VW originally re-flashed by APR racing(where you send in the ECU, and they send it back) and I gained about 23hp or so, but I had the car dyno tuned a year later, and gained an additional 10hp, so 33hp total.

Thanks for the welcomes, and future advice.

You ever get the CAI with the velocity stack? I was thinking of making one but have not decided on the material and were to place it. If your coming from VWvortex than im sure your familiar with the modshack CAI, I was thinking of a similar design running some aircraft grade ducting at a 60* angle coming from just left of the driver side fog light with a velocity stack attached just after the filter, of course that would require the battery to be move to the rear of the car.
