Hi people,

I have owned my 3dr for about 10 months and due to a freakish failure of an oil filter I have spun a bottom end bearing and am ripping the engine out this week for a rebuild.

As I have only had the car 10 months and most of my knowledge is of Nissans can people offer advice on the following:

What is the typical rule of thumb for the largest bore you can run on a 500hp setup before you have issues?

What is the general rule behind why everyone runs such low compression? In Australia I have access to 100RON pump fuel and/or E85 so looking at running around 9.0:1 compression but guess valve to piston clearance can arise as an issue.

As a general overview my engine is meant to be:

200 LONG STUDDED BLOCK
PERFORMANCE CAMS/VERNIER PULLEYS
PORTED HEAD


The engine is meant to be lots of things but guess I will know soon enough when i rip it down. It does run a Pectel T2 and T38 @ 28psi
