What parts?

Some are available here in the states, some are OEM on USDM models, some are JDM/Euro only.

All parts around the engine (valve covers, timing belt etc) are identical to 1996 USDM EJ25D (not 1997-1998, just 1996), except for the water pump which is identical to USDM WRX/STI.

The 95 sti I think is an EJ20K. Regarding what source parts from there is a parts thread stickied at the top.

JDM '95 is EJ20G...

You're confusing USDM Model Years w/ Japan. We always sell cars here as a year newer than they actually are.

USDM 02-07 wrx has a td04 13t.
EJ20g wagon motors have td04.

jolly, if you want to run 18psi you need to be running robs 550 tune or something similar.

Tuning my car is a big issue. Being it's a jdm motor nobody can tune it. Will it not run proper?

Tuning is a big issue period. The JDM ecu's are fairly aggressive tunes to begin with. Turning up the boost will increase the likelihood of knock which will increase the likelihood of FAIL. Other then increasing boost are you doing any other supporting modifications to back that up?

Most of the usdm tuners will suggest going with a FMIC or a bigger tmic and an AOS if you want to go aggressive at higher boost. I have an AOS and feel in some cases I think the AOS is a good idea; in other cases I think it is not required and a lame excuse to buy shiny crap for your engine bay.

In any event an aggressive JDM ecu + more boost with no supporting mods doesnt seem like a well thought out plan. Just because you can crank up the boost doesnt mean its a good idea.

Well I have an after market down pipe full exhaust k&n air filter (will be making my own cold air intake). So not much but a little to support. As of the intercooler. I will converting to a front mount. But I will need to look at one that has this already.

Although I am new to the forum and subarus. does not mean Im new to motors. I understand that in order to get more power I must do more than gain boost. But I believe my question was if it would be safe to run 18psi in this motor. I dont believe I asked anything about how much power i would gain.

Your specific question as to - if it is safe to run more boost with your engine is a loaded question without a simple yes or no. Safe means no knock.

Assuming that at 18psi of boost you have ZERO knock then sure you can absolutely run 18psi.

The amount of boost is not material. Safe is merely a matter of if at that level of boost there is or isnt knock which is why I asked what supporting modifications you have done to facilitate running 18psi.

The reason people run AOS, FMIC or bigger TMIC as supporting modifications for running more boost is to decrease air temperature in order to reduce the likelyhood of knock. Also the fuel you are running could be considered a supporting mod. 94 octane is probably a good idea.

A wideband sensor to tell you if your running lean at higher boost is probably a good idea as well.

The answer is no. for more than 16 psi you will need bigger injectors and the ecu tune to match.
