Like the title says... What are the advantages of having a typer head on a gsr block? I can't really see the difference because my friend bought a hb with a gsr block/typer head and he's saying it is indeed faster then a full gsr motor.

Q: What are the advantages of having a typer head on a gsr block.

Q: Is that setup truly faster then a complete gsr motor?

I'm kinda stumped so if you guys can help me out I'd appreciate it.

 

advantage
1. its a type r head first of all
2. lil bit less compression so u can run turbo
3. status (if that matters)

power
1. compression is perfect good for higher rpm's
2. head is stonger built good for high boost if u run it
3. its a type r head

 

i dont agree..
type R head is just a honda factory polish head..

goin NA i would go with the GSR and get THAT polished.. with some good valve and springs an retainers...
more valve clearenc and high comp. LMA almost as good as type R

if it is faster.. i say no.. less comp = less power.. better flow yes it has..
so kinda tihnk is almost the same..

 

Type r head is a bit better.... its higher compression... so more compression means more power... and no u do not want more compression if ur gonna turbo ur car...the type r head comes with a factory port and polish... and bigger cams and a better valve train..pretty much a stronger head... but not better for turbo because of the compression

it will give lower compression in this application.
it's in no way "stronger"(it's a B16 head with a P&P and different cams-no big deal).it has slightly stiffer valve springs,so it does have a little higher potential rev-limit.the cams aren't really suited to forced induction.
i can't see the money it would cost being worth the benefit if you plan to turbo the car(or even if it will stay NA).if it were me i'd spend the money for a good intake manifold for you P72 head.
if you want to go inside it,there are plenty of people who can port and polish it,aftermarket valves that are made specifically for turbo use(and much stronger than any OEM Honda valves),aftermarket cams that will make much more power than the ITR or GSR stock cams.
you can see a pretty big gain with little money with just a better manifold.for the money you'd spend on an ITR head swap,you could build a much better performing GSR head.

i didnt exactly mean stronger or anything...i just meant it has better parts no doubt... i never said it was magical head... even if theyre only slithly better they are none the less better... but i learned somthing today... i didnt know it gave u lower compression... how does it lower ur compression?

the combustion chamber is bigger.
the money can be much better spent to make more power than this mod will make.

A type R or b16 head for that matter.. does NOT give as high comp on a GSR block that a GSR head will...

You don't need less compression to run a turbo set up. It will work perfectly fine, and very efficiently as long as fuel and tuning are up to par. As far as status and it being a "TypeR" head, I don't see how that factors in to performance.

Perfect compression for higher RPM activity would depend on many other factors, cams, exhaust efficiency, fuel, etc. The stronger valvesprings and retainers would assist, but if a person is running a lot of boost, they'd usually change them out anyway.

Not being able to run a boosted motor on stock GSR or ITR compression is a misconception. Again, fuel management and tuning are the biggest factors.

P72 heads have a quench area that goes all the way out to the surface, PR3's are recessed.

 

So much misinformation in this forum these days.

It seems like all the knowledgable people left.

If you don't know what the **** you're talking about, don't throw your two cents in.

to rodrez and chris for the right info. sheesh.

i'm proof of that.over five years of boost on a stock C1-first at 10psi,and the last three years at 12psi.no problems AT ALL.

Thanks for all the helpful info to Chris and Rodrez...

Stock block/head?

TOTALLY stock block and head.never been opened up.
