I am currently building a b16 block for turbo, and I picked up another b16 with p30 pistons. So my question, and yea I did search, but I found different answers to which compression ratio these pistons yield. (b16a block, p30 pistons, p72 head, oem head gasket)
It ranged from 10.8 to 11.6. Which is it? Also, I have a dry NOS nitrous kit already installed in my car, can I use the kit with this motor?
I am only using this motor for the summer, until I have enough for my turbo kit, then that;s going in along with the built b16 motor. Any help is appreciated.

 

So is it safe, or will it blow as soon as I spray on it? I don't want that to happen

 

lsvtec with p30 slugs was one effcient *** setup!!! 40-50 single shot of n2o yielded 12.1 @ 110 on pump gas.

The setup was beat on continuously and still lives on with its new owner. If I had teh opportunity to build another setup like this I would deffinetely use the p30 slugs!!!

What head were you using? And if I'm not mistaken, the b18b block yields a lower compression than the b16.

 

same head as i specified i was running ls-VTEC - Keep in mind I am from California where the highest pump gas rating we have is 91. In addition I ran a skunk2 program with the n2o and the timing was set at 14 Degrees.
