Well a friend gave me a brand new set of JDM Type R pistons today ,, still in the bags, i opened em to look at em , thats about it . He had no use for em and owed me so hehooked me up .
Well i was gonna keep em for back up and then realized they wouldnt work for mne becuase the compression is higher
So i wanted to knwo exactly what compression these are and what a good selling price is for them . I figured ill use the money to get my forged ones.
He said something about them being coated with some **** at the bottom of the piston to reduce heat buildup? or something .
anyway let me knwo a good price and ill post em up for sale or trade

 

Just because the compression is higher doesnt mean they wont work... whats the application?

TUrbo . I was getting thme as back up in case i melted a stock one, but found out they weer the JDM ones., so they will be sold . I like the comperssion I have, no higher. . . . and when i go with forged the lowest they will be is 10:1.
anyway any answer the orig questions?

 

The compression of USDM ITR pistons are 10.6. The compression of the JDM pistons are slightly higher with a compression of 11.1.

 

How about some stock GSR piston, even trade.

I have some set in stock. This will yeild you lower than your current compression.

Let me know,

no thanks im looking for forged pistons to trade if possible and no lower than 10.1:1
