8.8 compression doubles the horsepower! hehe

 

Why does one of the pictures have "Nissan OHC" on the valve cover ,whereas the rest it just says "Nissan" o.O

 

Because that's an OOOLLLDDD picture of the engine :P

and according to the OZ engine calculator, my car has 8.4:1 compression, since it has a Fel Pro Headgasket! lol

omg, will my ZX be the first to have twice pipes? that can't be... SOMEONE must have done it before, right?

 

Welcome! That's a very clean zx! I like the J-spec valve cover, I have one coming in the mail too.

 

twice pipes were made for the S30 not the S130. and i had them on my S30 i even have a youtube video.

 

exactly, I know

I'm having a custom set made
