i was looking threw some forums and i saw that someone said you cannot have CTR pistons and skunk 2 stage 2 cams in a b16....is that true becuase i am planning to order this soon

 

My son is running CTR pistons and BC 4 cams in his B16 with great results. It's
also a daily driver but was built by a good shop. Good luck!

 

^ stock head gasket?

 

i have it in my B17a but i ran a 60mm HG because i was afraid of the high compression for DD

i don't know for sure, but definitely check for piston to valve clearance...you might need an extra thick headgasket to make it work.

 

I ran sk2 stg 2 and CTR pistons in my B16 for 2 years never had a problem

 

i have jun3(=s2s2) with ctr slugs on my b16a.

no problems 180whp on the dynojet.

with oem 3 layer HG? and 93 octane?

 

how thick of a head gasket should i use if im using ctr pistons in my b16 wit itr cams

 

what kind of power and torque figures? also any other details of the setup? thanks

 

its a jdm b16 im just putting ctr pistons wit the stock head im just using that motor to get me around while i work on my k

 

Just keep in mind that B16 + CTR pistons = pistons coming up past the deck (out of the hole). There are lots of better choices for compression over CTR pistons. Seems everyone just assumes that huge dome = huge power. This isn't always the case. Look at the results a few posts up. 180whp with stage 2 cams and CTR pistons...

 

just check for p2v and v2v, also degree the cams and good tune you'll be fine

 

use p30 if u want to drive it daily,

 

Hybrid96EK what other type of pistons do you recommend besides CTR in a B16A?

PR3's or JDM ITR's.

 

CTR or P30 are BOTH great choices for a daily driver B16!

 

bump

For what reason?

 

Stock OEM head gaskets are proven to work on these setups. You'll be safe.

 

If you go with pr3, p30 or jdm itr pistons you mind as well leave it stock. You will be running a stock compression motor. If you are going to put ctr pistons in you better port and polish the head or you will feel disappointed. Look up in the all motor forum all motor dynos. YOu will find the dyno of guillotine and his b16 with ctr pistons. He did his research and put together 200hp b16 with ctr pistons.

I had this setup before and it was ok. THen I slapped on my ported head and then I was pretty happy. Just changing the bottem end doesn't make these motors powerful, you need to concentrate on the head. That's where most of the power comes from.

Just my .02

 

oh, and I ran the ctr pistons in my b16 with skunk2 stage 2 cams AND a mugen thin headgasket.

JDM ITR pistons or P30's would not be a stock compression engine. It would allow for a slight bump in compression while still maintaining a good reliable DD setup. CAN you run CTR's with xx headgasket and xx stage 2 cams? Sure. Is it a good idea? No. Piston to valve clearance was almost certainly not favorable with your setup. If the person you referenced "did his research" then he would have noted the difference in weight the CTR pistons have over stock, the way the rather large dome messes with flame travel, and the idea that yanking timing to compensate for the high compression would counteract the gains one would even get from the pistons in the first place. Sure, maybe you can get away without pulling timing for the winter, but out here in California its not uncommon to see 100+ degree temps in the summer. Combine that with an engine thats kicking out 11.9:1+ compression and you will either be detonating or riding on the edge. That doesn't make a good "reliable" setup in my opinion. The max I would run on pump gas for a DD out here is 11.5:1, even then its a touch on the high side. You don't need an assload of compression to make power people. Anyone ever note what pistons Omni used in his 200whp B16 build? You won't find CTR pistons there...

 

I live in so california where there is mad heat. I feel if you are going to spend the money to change out pistons for another set of oem pistons on a b16 its not worth it to bump compression to 10.8. Its just not worth the money. Mind as well just get 1.8 liter motor. But that is my opinion.

If you are looking for high compression with a flat dome in a b16 you are going to have to go aftermarket, which means you need to buy aftermarket rods as well which is alot more $$$.

This is somewhat of a budget build in my opinion. Best bang for the buck would be ctr pistons.

 

My bro did the same setup in his eg. B16 with jdm itr pistons, port polish head, skunk2 stage 2 cams and put out 170 on Rage' dyno. He regretted using those pistons. Not tryign to start no e-fight , just trying to prove my point. If you are going for performance get ctr pistons. If you just want to drive your car to work and back every day get p30s or jdm itrs.

Or spend the $$ and get aftermarket rods and pistons.
