Just wanted to know before I got it all

Thanks...any input is appreciated

 

220WHP

 

Its gonna be slower that a stock gsr if you have a gsr block and use a b16/type r head, you'll lower your CR if you don't run dome pistons. Also if you use that IM you better get a tune.

B16 head on a gsr block is poormans type r.
Off topic, but allmtrteg: why do you have ls rods and crank in your gsr block?

 

I said a type r head not a b16. I have a brand new b18c5 head. And I will probably get high comp. valves to make up a little in the cumbustion chamber.

 

And the block itself is the same as a type r. exactly the same.

LS Crank and rods in a gsr is an OEM stroker kit, gsr stoke is 87.2mm and ls and b20 is 89mm. Thats usually why people do an LSvtec, to use the stoke from an LS and have the higher reving Vtec head.

 

allmtrteg is right it will lower your compression resulting in a motor slower than your current one.
Not only that but the b16 cams are less aggressive than your gsr ones.

why do you want to use the b16 head? why not just work with the one you have?

 

im gonna have to say between 150-155whp. The b16 head and type-r head are the same except for the internals and light port n polish, thus the compression will be lower. As for the type-r block and gsr block being the same, yes they are the same, but the internals are completely different. The type-r pistons are dome shaped creating more compression.

Type R and B16 heads are the same, as far as the CC loss is concerned, my mistake, i should have clarified.

Are you refering to the gsr block being the same as a type r, obviously you need to do your homework, Type R have domed pistons which increase CR. USDM GSR come with a - 0.60 CC dome. I aint trying to knock your build but it will have a lower CR than a stock Type R if that's what you're trying to accomplish

 

ok...how much comp. with I have with high comp valves and gsr block with the type r head?

 

Check out this link and add .2-.4 CR to account for your flat faced valves. With my calculations I estimate you'll only be at around 10:1 with flat faces valves on a type r head with a stock gsr block, but if you throw some type r pistons in there, you'll pretty much be at type r CR. The b16/type r head will drop you around 0.2 CR vs. a gsr head. The valves will make up for that, but your stock gsr pistons will still keep your CR down.

Youre going to lose compression with the type R head as already mentioned which isnt a good thing. Low compression with a type R head isnt going to make much power. Putting in type R cams in your gsr head will probably make more power than the whole type R head setup. Itd be much better with higher compression.

 

Why don't you just get some cams instead of the head, and put that manifold to better use.

 

Word, ditto, what you said

If you use that website posted, the diff in compression between the ITR head and GSR head is 0.2.

that would put him at .8 lower than a type r

 

yea lol... Well my head is bad and the valves are rubbing and im needing a new one so I already bought a brand new type r and im getting the type r cams too. So it should be good and ill maybe get high comp valves.

Correct, compared to stock gsr CR

What im getting at, is if his goal is a poor mans type r, good luck getting type r numbers if he's keeping the gsr block stock. With 9.8:1 CR and 10:1 CR with flat faced valves, he won't be be close to type r numbers. He will barely be at gsr numbers. Even with type r cams, he doesn't have the CR to take full advantage of them.

at 10:1 with the type head wont he be making more power than stock gsr? not much but a little
dont type r cams in gsrs with ihe gain power?

 

Yeah, type r cams in a gsr head will gain some power, not as much as they would though if the CR was higher, like 10.8:1 from USDM ITR or 11.3:1 for JDM ITR. I read in some engine building book that usually for every 1 point increase in CR, you can expect about 10 HP.

 

That would be nice if it was. The I would get some high comp pistons. Im thinking about actually getting high comp pistons and individual throttle body setup. It would be a crazy all motor setup!
