Anyone recommend a good place for head porting

I am looking to port my 01 ITR head.

I am looking for an honest place thats not going to strip my ITR head and put back GSR parts (heard of this happening once)

Thanks for the suggestions ahead of time

Prefer some place local but will consider shipping

 

alaniz technologies, http://www.portflow.com , http://www.pyr-racing.com

both do great work, one does it in his broom closet I think

 

my best advice is to leave the head stock.

on a turbo car, you dont need to port. ill get tons of **** for this and people disagreeing left and right, but the HP number a friend of mine put down recently is VERY close to the 4 digit mark and used a stock head. Ill just leave it at that.

 

I agree with you 100%!! If you are gonna touch the head get some vavle springs and retainers. Ive seen it done on a stock head put down 650whp with only valve springs and retainers.

well, say you ahd an extra head just laying around, and it wont cost you anything to part match it, wouldnt you realistically see some type of gains? That is what i had planned on doing, just getting an extra head and working on it, port match, polish yada yada...

Can you fully explain this art? Let's say a car putting out 350whp at 15psi on stock head, how much whp will it gain with a ported head? I'm in the process of sending my head out and would like to know if it will be worth it or not. Thanks Paul

 

a properly designed intake manifold should not need any kind of port matching

a d16 probably doesnt count as that head does not flow all that well. Porting helps on LS heads and sohc heads, but most hardcore racers dont run them.

If you want to go really really fast, stock head and well designed manifolds with big cams on the exh side and big turbos. thats all there is to it.

 

Head porting is can help greatly. Sure if you useing a turbo, you can just turn up the boost. The fact is though when the job is done right, the boost becomes more efficient and you can boost less for desired hp. At G&S Performance, our in house flow bench and computor software can tell us exactly what needs to be done and where. We can find out all the slow and fast areas of the head, enter it inter the comp and have a perfect head porting every time. The best way we port a head though is with our ouw grinds of cams as well. Obviously the way a head is going to flow has to do with how much the valves get opened and at what rpm. We can sit there and dictate the when where how and why of any type of head....Mike

 

Very True. I would go with Portflow

 

I agree PYR P & P = GORGEOUS, and Peter is a nice guy too

art make that 730hp now just cleaning the ports with little mild scrub since it was dirty thats all stock head with ferrea valve train.

 

if you want to see a head flow check out a 1.8t audi vw head. those suckkers are crzy

those guys are good. they do a lot, and can do about anything you want.

ever seen a CRX with an NSX engine in the back, well, they built one, so check it out.

 

who here has actually had portflow, pyr or alaniz do their head work? what was the down time like?
