Default JDM Big Port Heads Vs UK 2002 STi Heads?

Hi guys,

Which heads would be better to use on an engine build? JDM Big port heads refreshed with better valves or standard heads with some porting and polishing etc aswell as better valves.

which will flow better? I try to read up on it online and just seem to get confused with people saying all sorts lol

hopefully someone can clarify.

Cheers

Eddy

The car needs to speak not the graph dude.

Either way, JDM or UK with some decent race cams will make a good setup

Banny, having been speaking to Eggy, I think once you have 'serviced' Eggy, you can have a look at my bottom end set up ...

Seriously though the options and parts sound interesting. I'll let Eggy be the Guinea pig and tag along later.

I'll find out the spec of my GT30 first to see what options i have available..... ******* cars been in the garage for two weeks being worked on, but yesterday someone came round to my house asking if its forsale .....
