So I'm taking the advice of a fellow NASIOC member, and starting this thread.
Since the other thread is strictly for the cool guys with Ver7+ ej207's, lol, I thought I'd give us OG ej207 guys a thread to shred!
I am currently in the process of a Ver5 STi Type-R swap. It was almost a Ver6 RA ltd, but the price was just right with the Type-R. Click HERE to Peep The Swap
Anyways, I am trying to dig up as much useful info as I possibly can on these pioneer ej207's.

-What kind of power can they handle stock?
Not much, 350-370 bhp tops.

Remap, bigger exhaust and a good panelfilter. Might need a walbro 255lph fuelpump also.

New shortblock internals, mainly new rods and bearings. But aftermarket pistons would be a wise investment. ARP headstuds also.

Right now i've got 325-330 bhp, but it's ready to cope with 450 bhp.

The rods don't like high revs accompanied with more horsepower, makes the nuts holding the big end rattle loose and you've got rodknock.
They've got open deck block so max safe hp is about 450.
