Default Time to upgrade the GXP

Well guys I am tired of having "stock c6" corvettes kicking my *** and was wondering what I can do to give them a run for their money. I have 5 grand to spend and was wondering what you guys think I can do to make my car keep up with these fast basturds lol.

Save up another grand or so and supercharge it!

Yeah honestly i think the best way to go would be to supercharge it.

I agree with them, hold out and save some more for a supercharger.

I would go full boltons with ported intake and a nasty cam with converter. Mild setup are running 11s@117mph which is on par with stock vettes ro better. This is with stock heads, a porting would be great too. Or slap a 150 wet kit on it. Or both.

GXP is as fast as a new SS, not as a vette.

You'll be limited to low boost with stock compression/internals. IMO, no fun/reason to go F/I if I cant go all out.

Put a FAST 102mm intake/TB on there, cam, full exhaust and stall (with trans cooler of course) and go take names.

no he wont, the stock g8 bottom end is stout. Should be able to make over 500whp+ reliably on 8-10lbs of boost, do some research! Hell parish is puttin down 600whp on the bonestock l76 with a house of boost turbo kit. I say fi is the way since you have plenty engine compartment space in the g8.

Bolt-ons and a shot of nitrous will put them in your rear view for sure. I'm a big fan of the blower idea myself though if you want to hold off until you have the extra money.

Oh wow! 500RWHP for $6,000+ for the blower kit! Where do I sign up!


GTFO outta here with that noise unless this is a competition to spend the most cash for the least amount of HP.

Cam, intake, full exhaust, nitrous, new set of sicky tires and enough left over to play with the suspension, trans, or whatever else compared to your $6k (if not more) blown in one shot for the blower kit

I know it makes power. It just doesnt make enough to justify the cost on stock internals. That GXP will see 480+ with the right boltons and cam and spray will bring it over 600 easy when it needs to be there. This board swings on F/I so hard sometimes people forget there are ACTUALLY lower cost options for speed out there.

i've been the bolt on big cam nitrous set up and if done again i will just go the blower route

6 grand for the blower is a lot for the horse power but not a lot for that much streetable reliable power

thats just my opinion from my past with cars

Great quote and spot on. Cam, ported intake, headers, and a nitrous with a Nano system. Very hard to beat when it's tuned right.

Let us not forget about the weak sauce LSD. Also the A6s dont seem to be having any wheel hop issues like the M6. So you might be fine with the stack axles in a A6 w/an upgrade diff

I have had a blower car, now I have a nitrous car, read my sig, nobody's swinging on anything. Im all about a cheaper ways for power, thats why i went nitrous this time lol. Your twisting stuff around. The point is: your first post said "the op will be limited to low boost because of his internals and compression". I disagree, power is power and the internals won't care what you use to get there. That being said, the l76 is capable of making over 600whp on the stock bottom end, it does not matter wich route you take to get there. I recommended going with a blower because of the extra engine bay space the g8 has and the boat load of tq the tvs 2300 offers, it's just an option, yes it's pricey.

Nitrous, or a home built STS rear mount turbo set up.
