I own a 1988 300zn/a I'm building my motor from bottom up, I plan to put a wet NOS system in it. Need help in what can I do to the motor to prep it for the NOS, any info would be helpful but I am mainley working on the lower half for now. Contacts would also be helpful.

 

Basically, a good motor should be able to handle up to a 50 shot of NOS without too much problem. After that, you'll need bigger injectors, stronger pistons, crank, etc. I'm not all that familiar with what else you can do to strengthen the motor. Nor would I even be inclined to tell you how much NOS you can run with any mods. Ask motor builders. The principles they use to build their motors can be applied to all shapes and size motors.

some people that run built turbo engines with high boost use the stronger z32 TT connecting rods and crank...if you want to get really fancy you might consider the above with forged pistons and metal head gaskets...also consider replacing all the hardware with racing hardware...ARP makes it...I bet with all that you could run 200 shot no problem
