Default V.4 or 5 into 04 WRX

I'm getting a complete JDM swap from a version 4 or 5 sti for my 2004 WRX. Everything I am aware of. ECU, Motor, Trans, Axles, Diff, Engine Harness uncut. Is there anything i should be aware of with the swap into my car?

Exactly... Why not? Its JDM so right off the bat it will make 60+more HP then his current motor, and be able to handle a ton more.
The only reason I can think against this would be if you ever had to pass emissions; if that was the case then I would swap only the shortblock.

Why will it be able to handle a ton more? A v4 block isn't unusually strong - and if he goes through with the swap, his mod potential will be seriously diminished. If anything, he should do a v7+ swap.

v4 is a step backwards... it makes no sense to rewire a GD for a gc motor.

The wiring for a V7 is simple into WRX. Not so for a V4 or V5. The downside of course is the significant increase in cost for the motor. You save money on the install and spend it on a new better motor by going with the V7.

bzzzt its in the EM so if he uses a usdm ecu (which won't work so it a mute point) it won't be any advantage

a ver 5 or later block will have the high density crank sensor (i believe)
when subaru changed crank sensors in jdm land isn't clear

the price on short blocks really isn that much ... look for a v7 or later or for that matter a usdm sti block for ~1500...

your going to need a retune either way
