I want to be able to produce high rpms number along with power. Which head should I use a gsr pnp or get a type r head?

Thank you for your help

 

Depends on your budget. I would not convert a type r head into a ls vtec, but thats just me. A b16 flows better and a gsr has stronger internals. Dyno proven a gsr head will produce more power over the b16.

 

with a b18b/a block i would slap a pr3 head on there, ex. b18c5, b16a, b17a head. with a b20 block the b18c1 head works much better on that setup.

Whats a pr3 head?

Thanks for your help

I'm learning alot from u honda/acura professionals

I readed that a b16 head with a job done to it has the same air flow as the type r head. So the type r is no more on my list, now I'm really considering a gsr thanks to what you wrote. I will continue to do some more research.

Thank for your help

it is my understanding that the ITR head and the B16 head are the same cast. just diff valve components

1. why not use a type R head? factory p+p, and better internals.
2. a b16 does flow ever-so-slightly better, but nowhere near a level you could possibly notice in real life. this increased flow was also for only a portion of the powerband (either midrange or topend, i dont remember), and the rest of the time, the gsr will flow better.
3. the gsr internals are not really "stronger"

basically, yes.
plus the gsr will yield higher compression due to the welds in the combusion chamber, so the gsr head will actually yield more power.
however, the b16 is most likely going to be easier and cheaper to come by. so, its a toss up. it's all up to you.

 

gsr head if you're running ls pistons

go with a b16 head if your piston compression is any higher

Why is this? I plan on using aftermarket higher compression pistons, along with rods and bolts, with also cams gears,shafts, valves,springs etc.

What should I do then?

 

If your going to basically strip apart the entire head and replace all of the internals then it really doesn't matter which head you buy. Yes the gsr head will yeild higher compression and will probably make more hp, however, it will be very costly and wastefull to purchase a gsr head and replace everything inside of it. I guess you plan on spending a ton of money on your head. Also, why not just buy a type-r head?? You will have plenty of revs and greater flow over gsr, so, in my opinion, you should just buy a type-r head. The type-r internals are great and you wouldn't really have to upgrade them, so that would save you some cash too. Though you will pay more initially....Its up to you tho, if you really want to go all out just buy a gsr head get a good p&p job, some nice ITB's, and spend a ton of money on your internals......

 

use a B16 head.......they can be found complete for much less than the GSR or ITR head and will perform equally the same.

get the B16 head ported properly and it will outperform and stock ITR head. the so called "porting" found on the stock ITR head isnt much of a port job anyway...

good luck.

I read something similar in a magazine article, but I wasn't really sure still.

Basically I have decided on the b16 head(but what year or type?) get it ported properly like you said and get some strong internals for hard revving and hp.

anything yall could suggest would be gladly appreciated.

Yall guys are of great help thank you really i'm learning alot thanks to u professionals

 

any pr3 head is fine. they are all the same, except the pr3 type r head is factory ported, etc... therefore, get whatever one u can find, but make sure the dizzy is right for your car...

 

I have a complete 99 gsr head for sale. Let me know if you are interested? Sorry I know this is where I shouldn't post this.

Mike-

 

use a B16 head, they are cheaper and will get you the same performance as the GSR and ITR. Good luck on your build and keep us posted!

not only is the b16 head cheaper, it is better. it flows better but mose importantly has a smaller combustion chamber than a gsr which means more compression. this was proven by the writer of high performance honda builders handbook volume 1. ive also read that the b16 head and gsr head were both tested on a b18 and b20 blocks and the b16 on both motors made more horsepower. dont get me wrong because it also all depends on the components used and machining. im just saying straight from the factory....

good luck with future builds everyone

i think you got it mixed up the gsr head has a smaller combustion chamber which yields a little higher compression. and the b16 head does not flow better, they're about the same.

correct

 

whatever one is cheapest... money saved toward headwork

just what i read from the book but thanks for the info

 

B16 - cheap and the closest thing youll see to an ITR with out being ITR.

I just put the ITR cams in my ls/vtec, love it

 

I purchased a b18c1 head for my car (pr3?). From my understanding the GSR will yield a higher compression (10 or 9.5:1 i think). The b16 head will yield an even higher compression than that (like 10.5:1 or 11:1). I think is right... ill be looking for the magazine with the specs in it. From what i have heard the gsr head will keep more lower - mid range torgue while the b16 will loose some. the b16 will give you about the same or maybe more high end horsepower depending on the tuning. hmm think i found a link for u.I could also be totally wrong.. not sure

i would get the b16a head since its cheaper than the gsr and r head. if u going to port and polish, add new vavle train than the b16 is the way to go. If u plan on keeping it stock than the r head will do. Why waste money on a r head when u going to port and add after market valve components. the R head is a mild port and polish head thats all it is.

 

It also depends on your plans... if you planing all motor route where you will be running high compression they a b16 is prob better. but if you sometime plan on running F-I then the gsr will prob be more to your liking.
