Hey guys, my type R has quite a few miles now and smokes a lot so I want to build the bottom end. What would be a good piston/rod combo for an all motor setup?

 

It really comes down to what you want out of your vehicle. Do you want it to be streetable, what gas do you want to be able to use in as depending on compression you may only be able to run a high octane gas etc... If you were wanting to keep it as a daily driver then just rebuild the stock bottom with OEM Honda parts and use a set of CTR pistons as they will highten compression, keep the ITR rods and maybe put in a Spoon 2 layer head gasket or simmilar if the compression isn't getting to high. You will probably have to clay the engine to make sure valve to piston clearance is ok.

 

I dont know what I want to do yet man but could you give me a good variation if I want to go daily driven all motor? I heard that CTR pistons are too high in compression for the gas we have here which is 90 octane. I was told that JDM ITR's would be better. I also want to go supercharged, whats a good comp ratio for that?

 

be careful with the CTR pistons as they have a high dome... just changing to CTR pistons will give you near 13:1 compression ratio...

 

superchargers suck. just throw in some .25mm overbore (81.25mm) JDM B16 P30 pistons (of course get the cylinders bored first). nice valvetrain and nice cams. make sure there are no restrictions in your intake or exhaust. get hondata S300 and have it professionally tuned. you'll be happy.
