I've searched around but still couldn't get an exact answer. I wanted to know if I should be fine.

I have a 2000 ITR. Im about to put in the supertech valvetrain. dual springs/flat faced valves/titanium retainers/bronze guides. I was also thinking about throwing in a two-layer headgasket.

My question is should I be worried about Piston To Valve clearance?
What is my compression going to be?
The local shop said it'll sit right at 11.5:1 and that I'd need to use race gas.

Also, I just found out that my pistons might have been changed to Factory Overbore, Will this change anything?

Your help is greatly appreciated and thank you.

 

No you'lll be fine.

 

having to use race gas on 11.5-1, . Let me guess chonge told you this ? you will be fine with 91. What cams ? also be sure to get tuned......by someone other then revline caugh caugh modified by kc ......btw your compession will be at 11-1 with a 2 layer

 

hahaha, so how did u figure i was from around that area? actually it was scott who told me that and i wouldnt give my business to revline anyway chuong tried to f my brother over and ive known his whole family for about 10 years now

 

With a good tuner you can easily run your compression as high as 12 to 12.5-1 on pump. Why raise the compression just to lower it with a dual layer headgasket. Run a stock headgasket and get a good tune. The key will be in the tune.

 

I like the location WheaMyRyceGo, but I know where you are located.

/cry

2 layer HG = RAISES compression. Stock is 3 layer.

No [freak]ing way is anyone running 12.5:1 on 91 safely. And even if you could... why? You would make more power at 11:1 advancing your timing.

Why tell someone with oversized valves, 2 layer hg, mystery cams and who knows what pistons that he will be fine with p2v contact? You have no idea, he needs to ask his engine builder.
