Default JDM gsr vs USDM gsr

What do you guys think I should go with..

B18C - 180Hp 126Trq 10.6 Compression (JDM GSR)

or

B18C1 - 170Hp 121Trq 10.1 Compression (USDM GSR)

I am asking because I am planning to go turbo, and I wanted to know if I should go with the GSR motor with lower compression?

What do you guys think?

its always easier to tune with the lower compression. but you will make more power at less boost. what management will you use? i would say go for it. and youll have a little more fun with it before you turbo. or you could go with the lower CR and boost a little more(if you want to). wow, i guess that doesnt help too much .

I was also wondering if lower compression pistons would be necessary on the b18c(JDM) for low boost(under 8 psi). The place I want to order from only has JDM's in stock.

So what do you guys think would be best..

It kind of sucks because the USDM motor costs about $300 bucks more..

Anybody else have any more imput?

I say get the JDM. With 10.1 or 10.6 comp, you're going to need top notch tuning. So save the $300 on the motor and just put it towards the tuning.

Will I have to end up, lowering the compression some how? Or would I just do as you guys are saying and just have it tuned really well?

with good tuning on the jdm motor

you should be able to do around 320whp on race gas - if not more

this is at around 9psi

320whp in a light hatch should give you high 11's


a guy around the chicago land area just put down 320+whp on a completey stock jdm gsr motor tuning was with smc+ and dsm 440cc this was one race gas to be safe...


to high whp stock motors
