b16motor

so i want to built a new motor and im thinking of a b18c1 with a b16 head.
since b16 head increases the comp would it matter if i put 12:1 comp pistons??
what do i need to do to the block before putting higher com pistons??

thanks for looking!

a b16 head would drop compression by about .2 points. what exactly is your reasoning for wanting that much compression? what cams will you be using? what octane gas do you have? how much power do you want to make?

you dont need all the compression in the world to make power.

i have stage2 skunk2 cams and i want to be able make a little over 200 whp and
I also have a b16 tranny with a stage3 clutch and an 8lbs flywheel.
should i just go with gsr head then??

200whp?

Have fun with that one, lol.

The reason somebody told you to put a B16 head has nothing to do with compression ratio, actually, the compression ratio goes down. What it has to do with is the B16 head has a better overall flow rate than the GSR making it a bit more powerful, it's known as "a poor man's type R." Though the difference will be very vague, the GSR and B16 heads have the same casting, only the Type R's have port work as spec (polished I think). --- That's unconfirmed - somebody told me that they have some port work as spec, though I'm not 100% on that.

If you wanted to make power out of that - If you were honestly shooting for 200whp, you'd throw those cams in a B16 head (so you have a bit better flow and compensate + some for the comp drop, bump the compression by 2.0:1 (you'll have to use higher octane such as 93 fuel) with a edelbrock victorX intake manifold and a JDM ITR header. Get that dyno tuned and you should be able to hit 200 assuming the motor is in good condition. Or you might fall a bit short and upgrading to stage 3 cams should fix that.

People say "D series don't respond well to bolt-ons" - which is true, but ALL naturally aspirated 4 bangers don't respond well to bolt-ons.

gl on your build but with that compression I think ur not going to be able to use pump gas. is this gonna be a street motor?

He should be able to use pump gas.

A cam with nice overlay (haha on a street car) will decrease the compression ratio a bit.

This is pathetic talk in terms of a street car, but yeah, you hear it all the time when talking about drag cars =]. You should be fine on pump gas - but you'll have to use high octane.

shouldnt he be using higher pump gas anyways? i was told use highest always for b series motors because of higher compression.

b16motor

well of course the head is going to have more than cams.lol im going to do a stage two port and polish, high comp skunk2 valves and valve springs and skunk2 intake manifold

you need to get your information correct. b16 heads have a bigger combustion chamber and brings the compression down a little. if you put a b16 head(stock onto a gsr block(stock you will lose .2 in compreesion cause of the bigger chambers than the gsr head. and a lot of ppl say b16 heads flow better but i,ve seen both flow the same.

i'd say buy a complete gsr and build it with some p30 pistons, cams, and valvetrain. a simple build like this will get you 185hp. i've seen and done theis many times
