Hi guys, I've searched many places but was unable to find this info....So I ask here...

As for my next project, I want to build a brand new Type R motor. I am looking for RM valvetrain but as for the bottom end, I was thinking about resleeving the block to maybe 84 - 84.5 (maybe w/ golden eagle or darton sleeves) But my question is, what's the highest compression piston I can go with? This will not use turbo.

1. passing emission - highest compression?
2. donot passing eimission - highest compression?

Any help would be very much appreciated. Thanx guys

 

well does your car have to pass emissions? if not the highest i would go is 12.5:1-12.8:1

Well, just incase I need to pass emission..what do you think?
I plan to run somewhere around 230-250 whp.....I don't know how easy/hard
that is

 

its not hard it will just cost money

Oh trust me, money isn't an issue....I'll be getting a brand new type r engine w/ lsd tranny straight from dealer....I know this project will cost me alot...I'm guessing, near 30G after I'm done with the whole car...

 

hey can i have a fixed up car but with low compression so i dont have to play those high gas price? i kno i'll lose hp but how about torq?

well you wont see much of that with out the compression

 

hmm....a GSR has 10:1 and type r has 10.4:1 if I'm not mistaking.....

 

the USDM gsr can take regular but knocking can accure so u have to use plus and i think that sucks ahaha o well. so yeah im hearing that rita is going to make the gas price up to 5 bucks in cali

 

30gs for only 230-250whp, youll get more than that from 30grand, ive only spent about 4 grand and i have about 250, with 30grand you should be able to get atleast 350. No im not turboed either, ported heads and 11:1 compression and bolt ons.
