Depends on boost. Id say between 100kw to 220kw.
I recommend a full aftermarket ECU, forged rods and pistons and a bigger turbo to take advantage of the big cams as an EVO7 turbo is too small and will restrict it at 7000rpm.

i think you need to ditch the apexi piggy back crap for a stock evo 5-8 ecu so you can reflash it or a standalone ecu to tune properly

power wise...alot of pioneering for 300whp or less

post pics when you get a chance :!:

Why sleeve it?
.5 mm oversize pistons would be cheaper and more reliable.

It's got to be better than a 4G63 apart from the extra stroke.
Power? until something lets go.

No need to sleeve with 82mm.

Got the same set up with 82.5mm cp pistons no sleeving required.

he is probably using the stock 81mm pistons from the 4G93T so re-sleeing the block was required

import duty is probably to blame for that

Ahh I have seen someone do that before.

Friend purchased a set of wiseco pistons in 81.5 for his 4g94. And they were a 1 thou undersize according to wiseco this is standard practice to them.

My mate has to resleeve his block to meet the correct piston to bore clearance. ;( what a pain.

Good luck anyway gona be hard shutting the bonnet with a 4g94 block without modding the bonnet hehehee..
