Like the topic says, jdm itr pistons(11.5cr) or wiesco(12.5cr). My problem is that on 12/31/06 i dropped a valve and busted 3 holes in the #4 piston, bent the rod and scratched the cylinder wall.


Now here are the options:

1. Rebuild the motor using jdm itr oversize pistons, or

2. Purchase a jdm itr block w/12.5 weisco pistons machined by comptech. Block was used 3 times in the us touring races. Then keep the other block as a spare.


Keep in mind that the cost will be a $200. difference. This motor will be going in my itr which i dont have to drive daily, probably every other weekend so i don't mind spendind the extra cash on 93 octane.

As far as other mods, port and polish head, 3 angle valve job, twm itbs, sk2 stage 3 cams, springs, retainers, aem cam gears and toda timing belt.

My goal is just to have a descent, well tuned R. Thank you in advance for any help, advice and/or suggestions. I am open to all comments, positive and negative.

 

actually that block is an obd1 gsr block, i was interested in it till i found that out...i dont want to mess with it to try and get it legal for nys inspection...

 

I thought it was a type r, not interested now.
