Thread: 04 Grand Prix GTP MODS any ideas?????

Yeah, #5 would be a new bottom end with those mods.

Think along the lines of a 3.6" pulley...and a tune...and making your own intake instead of wasting over $300 on that junker from K&N.

Link in my signature.

Click it and read it brutha.

My ideas are 1. k&n cold air intake
2. Headers
3.Exhaust
4. then upgrade to a 3.4 pulley.

just want some opinions or other ideas.

THANKS

3.4 pulley is too small , like blue said click on his link and read up. You will definitely need a tune and scan for KR.

READ/

THE THREAD/

I just linked.

Has all the info in there you need.

A tune is a tuned PCM.

There are links in that thread about KR as well.

You need rockers or a cam to go below a 3.6 pulley. Also with the 3.4 if you drop to it in the future will need bigger injectors

A ZZP PCM messed up my car.

Other's have had good luck with them.

Go buy a DHP PCM from 3800Performance if you want a canned tune.

not sure i agree with this thread.

with an intake, headers, and a proper tune i would be willing to say that 3.4 would be doable on some 'okay' timing numbers.

Ok here it goes - Make your own intake (open cone) http://www.grandprixforums.net/simpl...res-33351.html ,autolite 605 plugs , put some headers or plog here is a write up if you install Speed Daddy's http://www.grandprixforums.net/speed...eup-32920.html , stock exhaust anything out there sound like crap for this type of car (you could go with slp or borla) or just STOCK. MPS system (modular pulley system (3.6 will be the safest after doing the mentioned mods, scan for KR first ) You could scan for KR with an aeroforce scangauge (install one worth the investment) . Get a TUNE, find someone that knows about tunes and get er done.

14* isn't ideal here?

Yes

Research.

KR is bad.

You want "0" of it.

That's why I told you to read that thread I linked you. Because it has a thread about KR in it.

KR is knock retard.

You have it when you can't flow efficiently enough. Thus, the car knocks, the PCM pulls timing. In a nutshell, its bad. It's what destoys motors when you run too small of a pulley.

Black and white enough?
