just wondering where a good place in perth is to go to get a head ported a little. and how much would i want to get it ported if im goin to get at least a stage 3 (most likely higher) cam...?? and how much would you be looking at to haev this done. and is it ok to get it ported before u get the cam or is it best to get it done afterwards..??

go to All Tourque

Porting for a more agressive cam is a good idea, also dont forget hevier valvesprings.
The only problem with porting is the ecu, if you go too far with the flow rate the ecu will struggle to compensate. I do konw that JMM use porting to lean out their fuel mixtures.
I also found when upping the comression the ecu runs alot richer! I think it must set of the knock senser and it all goes down hill from there. So i think if your planning on going fairly wild with the head, look into some kinda chip/ecu to make the most of it.

I think you you should get the head played with, and then once you know the compression/flow, ring up a cam place and get yourself a custom grind. I made close to an extra 20rwhp form going from a stg 3 crow to a custom grind. You may not get gains like that without a aftermarket ecu, but the cam grinders know whats best when they know what the rest of the motor is like.

yeah im goin to get ems (spoke to u b4 bout wot u got).
ill speak to the guys at all torque when i get a chance.

cheers.
