im going to buy a spare vtec head to build up and swap it on to my motor. i can get an uncomplete b16 head for dirt cheap. im going to do a p/p job, skunk2 valvetrain components and skunk2 manifold. i plan to but ITR pistons to bring up the compression.

is it ok to use a b16 head, or should i find a gsr head?

TIA

 

the b16 head has a bigger combustion chamber, so that will drop your CR a little bit. I think the the GSR head might have better flow also...but I am not sure about that...anybody ?

I since you are speaking of dirt cheap b16 heads...often those are the old ones. Some of the older B16 heads dont have dual valve springs...or so ive heard.

just hearsay....some things to think about Im sure if you do some good work on the B16 head, it will be great though

 

i run a b16 head on a b18c block and i have had nothing but good stuff come from it. The b16 head is actually built for higher compression pistons. The gsr combustion chanber is actually more flat than a b16 head. I run 12:1 Arias pistons and i havent had any problems....pushin like 250-60psi on all four....

 

sweet

 

Use the B16A head, it is pretty much the same as an Integra Type R head but with out the hand porting.

 

If were going to do a build up....Full b16...or you like the GSR/with b16head?

 

i was planning on just slapping the built head on to my gsr block

 

It will drop your compression about .2-.3

You'll have a poorboy ITR engine.

 

i can live with that i guess. whould a thicker head gasket help out? or would that be too much?

 

just mill the b16a head about 15-20 thousandths of an inch... plus easy intake manifold upgrade to Type R with the b16a, GSR you would need skunk2 (more $ than the stock ITR).

cool. thanks for the info. anyone know the price of a p/p job?

crap! portflow is 9 bills!!! is that ampount worth the hp i'll get by doing this?!!

 

i say work on the bottom end first

 

i did dpr stage six work on my last ls/vtec rex... the price on that was 1500 dollars and all i can say is that with cams you get wicked horsepower. the motor before the dpr head was a screamer it would pull all the way to my redline which was set at 8500 rpm. after the dpr head it would RIP and i mean RIIIIIP right through the gears. before the head power was at 190 wheel hp and 135 lbs of torque... after the head with v-afc i made 210 wheel hp and 150 lbs of torque. not only that but the power of the motor was increased from about 4500 all the way to redline.
oh and if the power wasn't good enough of a reason to do the work... the sound... jeezus. before it was a click, the motor got louder and then it pulled. after you hear "click" and then the motor just screams, it was tons louder along with the power.

 

is that ampount worth the hp i'll get by doing this?!!

turbo, yes its worth the money, na hell no. think about it, $1500 (half the price of a turbo) for 15-20 hp? not to mention the toruqe loss. And most of his gain was probubly through the vafc.

Ill be running 12.5:1 JE pistons on my JDM GSR engine. 93 Octane pump gas. Im sticking with the stock HG though... dont want it any higher than 12.5:1

 

WHHHAAAAA???!!!!!!!!! IS THIS TRUE?!! Normal USDM b16 pistons?!!


man i cant wait to finish this project!!

But i can get 93 and 94 octane gas regularly... Ive heard that this is safe... Should I get a little lower CR pistons? Mebbe 12:1?

 

B16a flows much better than the GSR,stock-so any porting you do(if done correctly)will be a bonus-plus you can use a better intake manifold like everyone else said.

 

Toulene is alot cheaper than Octane booster. Does the same thing too......

Just make sure you mix it right

Need more info? Just ask....I dont feel like explaining it if noone cares.

if I get the USDM b16 pistons, is it better to have them on b18c rods or have b16 rods as well? What's the market on the b16a pistons and which year is best?

 

THE PR3 RIGHT? OR IS IT THE P30 PISTONS. hOW DOES CM MATCH BETWEEN THE TWO? IF YOU SLAP THEM ON ITR RODS, WHAT'S THE ADVANTAGE OF THAT BEING ON GS-R?

 

hey foolio =P talk to me later about having the head ported I got a new black and decker dremel and about 3 stones, I think we can do it ourselves! and we can flow test it with my shop vac when were done, and forget stiffer valve springs we can just heat and stretch out the factory ones to make them longer. And I have a pretty straight file to mill yer block with and get the compression up bada bing badda boom... For reals though Ken, I know a guy that does heads that's local. Maybe we can get you some good stuff or a nice port and polish for that head for a reasonable price.

 

always the comedian.....


cool. I'll talk to ya about it later
