My only concern is glow plug someone said the p3 is a direct replacement or can be used please quote me if am wrong,
I know some people that use the P3 in nova engines and say they have no issues.
The P3 is a hotter plug then the recommended CT06 nova plug and I have heard the P4 is actually better to use in Nova engines because its a little cooler then the P3.
I've also heard that if you use the P3 it is recommended to add a .1mm head shim for timing/firing purpose.
