Is anyone using High CR dome piston's with around 18psi?

I'm looking for a 10:1 CR + 18psi + race gas + Phased water injection

anyone?

 

10:1 flatop is what i used with great sucess the dome pistons will be really tite clearances.

The 10:1 and good amount of boost and your car will fly ..... thats given..

 

Where can I find a flat top 10:1 with a 75mm bore?

Just wondering if you knew. How much are custom made Piston's(usually)?
Say... made by JE?

Thanks for any insight

 

I have some flat tops in 83mm

 

you can get some custom units made for around 580 or so.

 

http://www.raceeng.com sells some flat top JE's that are 9:1 in any D series engine with a ZC/D16A1 Integra head. If you had some chamber work done to your head to reduce the chamber volume (ie, material welded in to give you additional quench), you could get 10:1 compression using those pistons. You can also mill the head a bit to up your compression, but I don't think you'll be able to remove enough material to get 1 full point increase.

Really? looks like I'm going that route then!

Thanks a lot!

 

Give the guys at JE a call and ask them about their custom pistons. I believe they are around 600, but they may want you to order at least 2 sets. That's what Wiseco told me.
