I will be building my engine over this winter with CTR .25 over pistons and a Mugen headgasket,and CTR cams.Will a VAFC,Mugen chipped ecu,and 93 octane be enough fuel management for tuning?Anybody else running a setup close to this?

 

I am no expert but aren't you suppose to use a stock headgasket with the CTR pistons. Someone please correct me if I am wrong, that is just what I heard.

 

sup man, sounds exactly like my old setup, im pretty sure u knew kabe, used to own my type r. get some forged pistons. ross will work with stock rods. wisecos would be even better. stick with oem headgasket. i had the real mugen ecu and a vafc, but went to a stock ecu. kabe ran the **** outta the car, and i was only making 179whp/129tq with that setup on ctr cams

 

I'd rather use OEM pistons than aftermarket.I'm building my engine on a budget.I guess I will try maybe JDM ITR pistons and Mugen headgasket.That would put the compression at about 11.4:1 right?

 

do 99-00 si pistons and a stock headgasket

 

What will the compression be?

 

11:1, thought it would be higher. i guess either will work, but on the headgasket, most people suggest using stock headgasket as most others will leak eventually

 

Right now I'm running USDM type R block, milled Si head, Toda C cams, and mugen headgasket... no problems here. I think you'll be alright, as long as the head doesn't need to be planed or antyhing

 

I believe that the CTR pistons with the Mugen headgasket on an ITR comes to ~12.6:1, Chris had this in his car and on 100 octane with a JDM header made 200whp with 6 heat cycles and 2 miles on the engine.

or u can run p30 pistons with a spoon headgasket and be around 11:6:1-11:8:1 like me

If you know of a good tuner, they could do that setup on 91 with no problems let alone 93, good luck

 

I don't see the point in getting both a 'Mugen chipped ECU' and a VAFC. Why not save the cash and get a Hondata? Or just scratch the Mugen chipped ECU and get the AFC and spend the rest of your money on a talented VAFC tuner. And since you have an FBP ITR, then you must have a 00-01 ITR, which means getting CTR cams won't net you a single hp. Same exact specs are your current cams.

Keep in mind these are OEM spec pistons, and a headgasket, not Stage 3 cams, huge bore or anything crazy like that which would need insane tuning. These mods would only need a few tweaks with fuel delivery etc.

I thought the CTR intake cam had a slightly higher duration than ITR intake cam.I think I'm gonna go with JDM ITR pistons and Mugen headgasket.I'm a very un decisive person .I already have a Mugen chipped P28 ecu so that's why I'm gonna running that with the VAFC.
