N42 3.0 trackday build


Recommended Posts

I want to build a 3.0l for trackday use. 

L28 crank 81mm

light strong rods

light pistons 

I want over 300hp

this is my first Datsun but i have many years of engine builds. 


So now I want some tips of what is the best bang for the buck to build a 300+ hp engine

I think its "cheap" as long as you can stay under 6500 rpm, afterthat you need forged pistons and balanced crank.


Something to keep in mind.

I never write anything about cheap build?
