So why are GTP's fast?

[97rs4life]

the rwd holden cars have a different sc setup that is harder to adapt to our cars than what the USA m90 is...

all these ideas have been examined already fellas. trust me.

centrifical is the way to go if sc is your goal

[86iroc305]

dam worth a shot, i know the 3800s hold up well to boost, i have a buddy with a sc, intercooler, cam, headers and exhaust he was mid-low 12's now hes going turbo and should be low 11's, thats always a option to fab up a turbo setup

i think this would be a good start, i think the conversion is well worth it

again, it is NOT a direct swap and that kit would not be a bolt on kit for a fbody car. It is for a Grand Prix

The inlet would be right into the firewall. You need to cut and modify the housing to turn back to the front

So if I go through the trouble of buying an M90 and such, do the necessary choppin and welding to fit the top end off a GTP on an fbody than I can have a quick Fbody too?

if by fast you meen mid-high 14s that the GTPs run after wasting a ton of money hacking your car to get it to fit. Better results out of a powerdyne and much easier. Those you see running 12s or 13s are far from stock, upgraded pulleys sometimes nitrous.. etc.

[Derek]

to add, i dont get why people get the impression stock gtps are fast, a buddy of mine has one, i raced him from 30-70 in the ls1 and i had probably 6 car lengths on him and pulling? For what its worth go either turbo or v8, trust me ive been through it my SC v6 was pathetic at 6psi of boost, if i upped it then id risk internal SC failure. Turbos can give more power but by the time you upgrade stuff and buy a kit you will have spent more than getting a v8 motor or car.

key word i used is that it is a good (start). i think it is well worth it if you already have a v6 car, heck i want to buy a v6 just to do it and have it for a winter car.

there are also GTPs that run in the 8 sec quarter range your goal is not far fetched.

[97rs4life]

I know of only 2 grand prix's that have hit 8sec times, and they are shop cars from zzp and intense. Most people get to 10s on the gtp's. They are full fledged drag cars, not DD cars that are going 8s

[JoeliusZ28]

first of all, stock GTPs are slow until you do some bolt ons.

Second of all, I own both a 3.8 and an LT1, and while my v6 is no slouch for what it is: Ill be the first to tell you its gonna take a TON of mods to get a 3.8 to an LT1s starting point.

[cobalt camaro]

All the above reasons are why i swayed away from this, I talk to a bunch of people and this is the way i looked at it. Buy a turbo kit 4k, get about 300 maybe 350 horespower and pretty much be tapped out on the performance aspects for a 3.8 besides building a full out drag engine. Or spend 4-5k for an ls1 and 6 speed and all necessary equipment, and START out at 350 hp. Slap on a pair of headers and an exhaust and it will beat a turbo 3.8. It's completely up to you, but like others have said it's to much $$$$ just to get it to run freaking 13's. I hope to sell my engine and trans this coming summer and throw in an ls1 or ls2.

[81DaytonaPaceCar]

OK...I'll throw this out there.

If you are gawd-be-damned determined to turbo or SC a V6, just buy a Grand National motor and be done with it. GM has 15 years of development and millions of dollars invested in it. They're good to over 700 hp if you really want to go there.

Stop trying to reinvent the wheel.

That aside, just drop in a V8 and be done with it. Are you really telling me that you'd rather spend $3K+ for a turbo setup to have the same HP as what a LT1 would deliver for half the price?

It doesn't have to be this hard...

[86iroc305]

stock gtp/gs run from 15.0 to 14.7. high 13's can be with with VERY minimal mods to a s/c 3800 w-car, heres a common 13.8-14.0 setup 3.4 pulley, pcm flash, exhaust, cold air intake, i have a buddy went 13.8 on a stock pulley, but he has headers, throttle body, and different gear in his trans. i agree this stuff is "made" for grand prix ect. but if he wants to rock the v6 to keep his insurance down and still get 25-30 mpg more power to him.

sure he could just buy a v8 car but maybe he dont want to be like "ever other" camaro out there i think it would be cool see a force induction v6 car i know my regal gsx is a blast to drive, i was thinkin about forced induction on my camaro but thats still up in the air.

if he didnt want to go s/c he could always fab up a turbo, turn the exhaust manifolds around so the outlets are in the engine bay, fab up a y-pipe for the turbo, pipe in a down pipe, get a old grand national turbo or something theres plenty of ways to do it on the cheap, it would take time and effort or why wouldnt a sts style turbo work those go off exhaust in the rear, thats the same on both cars v8-v6 once it get in the engine bay it may be a little different but sometimes its cool to be different

his vin number would still say V6 to his insurance company unless he told them. Its not "cheating the system" any more either, because a high horsepower v6 isnt any less of a liability.

And for the record, insurance companies care a LOT more about t-tops than what engine is under the hood. the company nate was using when he had his 94 only cared about what kind of roof the car had.

my ttop v6 costs me more than i expected to with AAA

Yup, State Farm was going to charge me less for the same amount of coverage for a hard top z28 then my ttops v6.

They assume that all cars, with all motors are quick enough to cause problems.

Most people think of a 4 cly as slow.... TC and SC Cobalt and SRT4 owners know otherwise.

yea, i always used to say v6 insurance is cheaper blah blah, but i upgraded from a 1999 v6 to a 1999 ls1 car, i think my insurance went up around 50 bucks max over 6 months?
