Re: 1st day on here lol

Welcome to the site.

1) Buy headers. Speed Daddy's from EBay...you NEED headers with high compression and a GenV

2) Stock pump is fine...so are stock supercharged injectors as long as you stay stock pulley size...which is 3.8"

3) Bryant...'06 GT's ARE supercharged.

4) ZZPerformance sells the TB adapter...and I don't know where Joilet is, but I'd find a local that can tune...mail order top swap tunes aren't that great...and that has been proven on here...they are ok to get the car started...but that is about all they are good for.
 


Re: 1st day on here lol

Heads don't determine the compression...the pistons do. N/A cars have 9.4:1 compression and supercharged cars have 8.5:1.

I don't mean to be a douche...but read about these cars...a top swap isn't the easiest thing to do.

Read the Top Swap sticky and the Safely Modding Your 3800 Sticky. They are in the General Tech Section and the N/A Section.
 
Re: 1st day on here lol

headers are more difficult than doing the head gaskets.

And thats only because most cheap headers are a PITA to get together the first time.
 
Re: 1st day on here lol

i knew the compression diffrence thats y ya switch the heads the bottom ends the same on gt and gtp i hear idk just what i heard not doin the swap till summer tho so yeah im doin my research i just knew the gen v setup was better

Bottom ends ARE NOT the same.

Pistons and rods are both different. GT block has higher compression...GTP block has lower compression...I don't think your understanding that switching the heads does nothing for compression ratio. Switching the heads allows for the injector embosses to be in the heads and not in the lower intake manifold like on your N/A car...
 
Re: 1st day on here lol

I see well thanks 4 the heads up : ) . You said my stock fuel pump should run this in its stock from ?

Stock form?

Your not stock if your modding...but your fuel pump is fine. If your wary about it...buy a re-wire kit. All you need is GTP injectors.
