I just got the block yesterday. I have a good setup in mind, but I want to know everybodys point of view on how they would make it fast and street reliable. Which rod and piston to use, what valve train to use with what cams?(staying with the gsr crank)

 

IMO, keep the compression around 11.5-11.8. Also, run a cam where you dont have to rev superhigh to make good power. 190 to the wheels isnt bad at all.

Good luck on your setup. I cannot wait to see what others say. Will be some good "food for thought"

 

It depends on how extreme you want to go with it... I would do something for the street personally and just throw in some jdm ITR pistons with some head work and JUN IIIs. It would have some nice compression and mean *** cams.

sounds good, 12:1 couldnt hurt, toda cams, 9k rev limit. Ported head and hondata. would be a fun car on the street

Theres so many ways. You just gotta find whats right for you in both what you would be happier with and how big your wallet is

 

acutally the highest he would be able to go with oem pistons is 11.3:1 thats with ctr pistons. this is because the b16 head has a smaller combustion chamber, and the b18c1 block has a larger piston to deck clearance. but you could always get a thinner headgasket, just make sure you have the head checked to make sure it is not warped at all. as far as making it go fast that depends on your budget. just do all of the NA basics. get some pistons, aggressive cams, header (SMSP ) make sure your car can breath in and out. skunk IM, larger TB and so on

 

um, with b16 (pr3) slugs he could get around 12:1 compression, so i dont know where youre getting your CTR compression numbers...
ill have a compression of around 11.1:1 with USDM ITR's in my b18a block, so i know CTR's are way more than that.

 

Also, the combustion chamber has MORE vloume than a gsr head, not less.

 

You can keep it mild and still make good power. I'd say for a street car, go to about 11.3-11.5:1 range (PR3, JDM ITR, P30 pistons fall in this range). Stock rods work just fine. Valvetrain will depend on the cams and how agressive you really want to go.

 

thanks for all the suggestions! My B16 head already has the following: skunk2 stage 2 cams with sk2 retainers and springs and skunk2 IM.

I'll be using forge rods and jdm ITR pistons. Will I be okay with using a thinner headgasket(mugen) or oem?

again, thanks for all the help guys.

 

When you choose pistons, order them as if you have a Type-R engine, the B16a head has the same cc as the Type-R head. If you order pistons for a GSR engine, then your compression ratio will be higher than the advertised spec for the piston. For the Skunk2 stage 2 cams I would rec a minimum of 11.0to1. If you want to run pump gas and drive the car daily, I wouldn't rec more than 11.5to1. I have a 94 Integra GSR w/ a 2000 ITR head. I have JE SRP 11.3to1 pistons(as per type-r engine) and Skunk2 stage1 cams, plus every bolt on available. With the Skunk2 P28 drag program ECU I'm using, I get very slight pinging on pump gas from 1500-2500rpm. A bottle of octane booster per tank plus adding fuel at that rpm w/ the Apexi Vtec controller eliminates the ping. NOTE: If you go with low expansion forged pistons(SRP), make sure your machinist hones the cylinders to the minimum clearance specs, otherwise cold piston slap and slight oil usage will occur.

 

i think a thinner headgasket would be alright in your case because those cams love compression, but if you are going to go thinner, get a quality peice like mugen.

 

well the block has a little over 100k miles on it. Should I change the stock rods out, or should I go ahead and use it? And if so, what do you guys recommend? Peace.

 

I was thinking about getting a b18c bottom end also to mate with my b16 head. I plan on getting Toda spec B's with the springs and retainers. What compression would be safe for me to still run on pump gas and a driven daily?
