Default answer.

parts for JDM? easy.

bottom end: crank/rods = EJ18 parts. most likely u will have for free bc thats what u are pulling outa it.

air filter? same as the EJ18
oil filter: ditto
turbo: im sure any bolt on WRX one will fit
header: i spoke to HKS personally in asia and they said that their header will fit
up-pipe: dont need on. its already no-cat and made outa incronel
downpipe: same deal. most likely usdm will fit. u probbly dont need it though, i dotn think 280PS will be slower than any exhaust modded GDA
some parts should be compatible with USDM legacy turbo. that is only a suspicion though
rallispec can get u gaskets (although USDM ej20 shoudl work fine)
clutch is identical to a USDM WRX GDA clutch. i have one in my attic. i have a exedy USDM GDA clutch on my 94 JDM STI trans

OR u can just buy stuff off UK shops or UK ebay. stuff is cheap there, bc ej20 impreza is so frekin common.

search FIRST, then PM!!!


I agree with the statement made. Impreza engines are basically like lego's in that they will all fit each other...to an extent
