i had bought a b16a and i thought of putting type R pistons and cam, would this setup gain some power on my motor if not would it be a good idea to go with a b20vtec?

try the NA forum better help

You will see gains because of the higher compression ratio and more aggressive camshafts, but a B20 VTEC done right could also yield some impressive numbers. What are your goals? Street car?

And BTW, you should have searched. There has been MANY threads covering this question.

ok...so if i have the type r stuff in the b16a will this setup be stronger than the b20vtec. becaues i ve seen some b20vtec with the compression 12.1.0 or something like that and if im not wrong a b16a with b16b pistons it will obtain 11.1.0 " i dont know the numbers, but im trying." but what would happend if it had the ctr cams, would the compression rate be a bit higher and would i have to tune my computer?

B20vtec FTMFW!!!!

EGR95

so b20vtec is better?

cadeMFjohnson

i like the b16a. go with type r pistons and crower stage 2 street cams they are around 450 bucks but they will pull mf'ing hard (provided you've also opened up your intake and exhaust sides well)

Deetz

LOL, type r pistons have LESS compression than the b16, you'll lose power on them. (ITR)
They also don't fit B20 blocks

Cams can gain power, but only if compression is increased

i have ctr pistons.

Deetz

that'll give you a compression of 10.8:1

you'd make about an extra 15hp with the cams and pistons

EGR95

so that is better than buying a b20vtec?

k20a2 haha.

anothersickhatch

the compression is going to be higher than that. it ends up being around 11.6-11.7:1 with ctr pistons in a b16.

Deetz

Ummm, NO!! here's the comprtession calculator, check the facts!!!

ok ... lets check, but if i put ctr pistons in my b16a is their any mods that i need to make them fit on the b16a?

okay bro... a B16 is a 1.6 liter engine a B20 is a 2.0 liter engine. the more displacement the more power you're gonna get. no matter what you do to your b16 on an all motor setup, you'll always make more power with a bigger block.

if you're building your B16 you need to match your c/r to your cams, your cams are what really determine your c/r.

rather then install new pistons, just bump up your c/r with a different head gasket, upgrade the valve-train/cams and a p&p. Get your self a decent intake and a decent header along with a high flo cat and a cat back exhaust.

it's hard to get 200whp out of a b16 but it can be done if you know what you're doing.

anytime you do work to your engine you should have it tuned to take advantage of your bolt-on and other upgrades.

you really need to use google and search more on the subject. throwing parts at your car won't make it faster. do research on the mods you want to do and do them right the first time!

true. i was checking compression in c-speedracing website and i did tons of comos and i did a b16a head with a b18b block with ctr pistons and the compression was 12.3.0. i think it was better than the b20vtec. or what do u ppl think

CivicSpoon

Screw online compression calculators; they all give different numbers. Look at this one:

If you really want to know how to figure it out, you pretty much have to do your own calculations. And threads like this, where someone asks what to do really aren't going to help you decide what the best option for YOU is. Because honesty, no one else really cares about what you do to your car. I don't mean that in a rude way, it's just realistic. Your best bet is to just check out what other people have done, figure out what kind of $ you're willing to spend, and how much power you want out of it. There are just too many ways of going about things with Hondas; engine swaps, head swaps forced induction, engine internal swaps, etc.

anothersickhatch

argue with omniman, who is the one who actually did the measurements and calculations. those online calculators are too general and don't take into account certain things. why don't you check the facts. that is hardly any kind of fact.

I think you should do a lot more research before you even touch the motor. Go to the allmotor forum and research the allmotor b16 dyno charts and set ups first. Then research the b20. There lots of threads supporting the 2 and lots of diffrent opinions and discussions about them also. GL and make a good educated choice.(there are threads about Lsv and Gsr or Gsr w/Ls crank rods also)all kinds of good info

EGR95

thanks. do u have any website that i can go to.
