with this combo i understand ill be at 11.8:1 CR with a stock HG. however, will i run into any valve to piston contact with a high lift cam such as a S2S3 or S2 pro-1?

 

clay it

 

yea that too.

 

why are u going with such a big cam on that small of a motor?


are u going for drag or road race?

s2s3 are rather big for that compression though..

so ive been told. just foudn a good deal on JUN 3s. those are more liek a s2s2

 

depending on how much the head was milled, i'd pretty much clay any b16a with ctr pistons. its a pain in the *** but definitely worthwhile.

 

Was the head milled? Piston to deck clearence with the CTR pistons, pr3 head, and stock hg is almost 0.

Also do you have the valvetrain for the cams? Just checking.

yea i have a beefy valvetrain. skunk2 springs and retainers and i havent purchased the valves yet becuasei m waiting to see whether or not i want flat or dished.

what do you mean piston to deck clearance is almost 0? im assuming this means with any type of cam the valves will probably hit. if thats the case ill just get a set of ITR pistons and rings and then mill the head a little to get me to 11.5ish :1

lemme know

 

The valve clearance is fine, The quench area is the part thats tight.

 

can you elaborate on what you mean when you say the quench area is tight?

i read that i have to machine 1mm off each side of the little end of the rods to use these pistons as well. any truth to that?

 

Yes 1mm of each side of the piston side of the rod.

Where the s and the arrow is, that is the quench area.



Also watch the very tops of the pistons like in the pic below. The corners are very close to the head as well

 

i see. how much of an issue is it on a head that hasnt been milled? with these pistons i should have 11.8???:1 CR so theres no need to mill for 91 octane gas. should i be good? wht precuations should i take? what bearings do i use on the piston end of the rod if its been modified?

 

No bearings on the piston side of the rod.

CR should be around 11.5:1

Should be no issue at all with a stock unmilled head.

91 octane will be fine. I ran my B16 CTR with 92 - 93 and a 75 shot wet nitrous with no problems.

Just be carefull of the pistons rings when droping the pistons in the cylinders or it will look like the one in the pic. lol I had the top ring pop out of the ring compressor on me when I was putting the last piston in and didn't notice it.

 

ok. sounds like youve done it. hha. so if the ring came off....whered it go that you didnt see it? do you know a place where i cn get new pistons and rings for less than 320? thats what im seeing at inline four but they seem high piriced on everything else. you dont happen to hve pics of the small end of the rod so i can see exactly where they get grinded.

but now that ive looked t the piston up close i can totally see how itd have plenty of valve clearance but a tight quench area. thanks for the help.

what kind of power did that motor lay down?

 

http://www.hmotorsonline.com, 169 for ctr pistons, you can get oem rings from jhpusa for 100 i believe, or advance auto has beck arnley rings for 66. Inline4 is an overpriced joke.

 

I got my pistons and OEM rings together off ebay for 225.00 I think.

Sorry no pics of the old motor. You'll see very quickly where the rods have to be milled once you get the pistons in.

Not totaly positive on the hp my motor put down. My times with it are in my sig. Could have been an easy mid to low 12 with a lower 60.

 

yea i talked ot him on the phone there. wanted 140 for an ecu chip obd0. it was then that i decided that were a little flaky.

thanks for the pricing.

CTR pistons in a B16 with a stock PR3 head and gasket is only 11:1 comp. If you want a little more compression just use a 1 piece head gasket which will yield you about 11.5:1 I really think Stage 3's will be overkill for your setup since they are really designed for bigger 2.0l race motors with serious head work. Buddy club Spec IV's or Skunk Stage 2's would IMHO be your best choice for this particular setup. I used S2S2 cams in a similar setup to your and made 200whp out of a stock bore and stroke B16 !LL W!LL's B16 Dyno Results! Stock bore/stroke! OEM Honda! 200+whp!
