i plan on getting new heads for my car, what would be the best ones to get, and how much hp would they give?

also what would i have to do to get my car to run in the low 13s without putting a blower on it?

 

I say go with AFR's if ya can afford them.... 13's shouldnt be too difficult to achieve.... welcome to the forums...

 

whats up man? a good set of heads would be either trickflow heads or afr165s....they should give you atleast 40rwhp on a stock 5.0, and to run in the low 13's all you need is heads and a good upper/lower intake kit...unless youwanna run a carb...but if your gonna stay efi then they also suggest the trickflow street heat intake..you also could get a nice size cam but cam, but the stock one does have alot of potential...all this with a good set of sticky tires and a good launch could deffinetly get you into the low 13s and probably get you into the high 12s....i would suggest some suspension upgrades also to help get the power to the ground....like uppr and lower control arms and subframe connectors and a good set of shocks,springs, and struts...these would help you well into the 12s...im sure you would run atleast 12.7...good luck man

alright thanks for the info, my name is rich by the way n heres a little bit about my car, 03 gt 5 spd with 18x8.5 in the front, 18x9.5 rear on toyo tr1's mac long tubes, mac h pipe with high flow cats borla cat back, bbk cold air intake 70mm throttle body & plenum 3.55 rear end and custom computer chip, i was thinkin about a short throw shifter and after i get the heads i want to get a more high performance clutch then the full eibach sportline suspension kit with wheel spacers caster camber plates n ball joints one more thing but im not too sure about is the bumpsteer kit any input?...

 

sweet setup... any pics?

as far as heads i've heard great things about afr 165's and bumpsteer kit will aide in handling/control with a lowered ride, for $150 get it and know that its done right.

Hey, Randy, which AFR's do you have?

 

205's

 

Cool. 225's here. I am considering TF's CNC's for my other 408. Cannot decide.

 

How many 408's do you have... [:-]
