I have a bone stock gsr in a eg hatch ima start a build soon and have a ? What modification do I have do to the head if any because of the dome on the ctr pistons to prevent valve slap or any other horrible thing

 

Sheez, this kind of question is just as common as the "what do I have to do to make an LS VTEC?" question.

If clearance is a concern the most plausible thing to do is to use a thicker HG, but out of curiosity why not another piston besides the CTR? Why the CTR?

 

Oem parts oem quality and the comprestion ratio is like 11:8 jus wit the pistons alone

 

Theirs nothing wrong with OEM but that C/R doesnt sound right on a bone stock GSR. How did you come by that figure?

 

you're looking at around 13:1 compression on a stock gsr motor, everyone here is gonna recommend a p30 or p73 piston. I personally had gsr motor with PCT pistons in it with no knock on 91 octane and it ran great, when my friend tried the same set up it pinged like crazy.

 

Yeah...and you make a post asking a question that's addressed in a thread that we posted about YESTERDAY!

And people wonder why we get pissed about this kind of lazy-*** attitude asking DUMB F*CKING questions!

The thread I'm linking answers your questions....AND HAS A LINK TO ANOTHER THREAD WHERE IT WAS ANSWERED NOT A MONTH AGO.....Next time why not do a little research before asking DUMB F*CKING QUESTIONS THAT HAVE BEEN COVERED OVER AND OVER AND OVER AND OVER.....

The motor is stock now but it won't be after its done I was considering itr oversize pistons also
