Re: engine mod or exec

The N42 head is from a 1970-71 240Z. That will decrease the space inside your cylinders and give you higher compression. For an easier fix, just put on a K&N cone air filter, a 2.5 inch exhaust off of your existing manifold and a 4.11 geared rear. That will get the best results with the least amount of money or time spent on a non-turbo.
