Default 2.5rs oil lines for a turbo.....

o.k. I might be scoring a very cheap wrx short block (crank rods, pistons, oil pan crank pulley and a stock wrx turbo...

Can i bolt the heads to the wrx shortblock with the wrx headgasket and how would I get oil to the turbo from the 2.5rs heads since they arn't meant for a turbo car...

also if i get a 5psi spring (for now) and maybe just a AFC and slightly larger injectors do you think that will be fine and no detnotation will be present...

Let me know if you can answer any of these questions for me.

another question is on the (older legacy) ej22t headswork with and would i have to do wiring work to get them to work with my stock 00 2.5rs ecu?

Yes the heads would bolt on. Would be best to use 2.5 headgaskets to match to the heads. STi Headgaskets would work. An AFC wouldn't work on your car. You would need to buy a Greddy E-Manage or something like that. As for the oil, you would have to remove your oil pan, and drill a hole in it. then weld on a fittling for the oil line.

And if you put the WRX shortblock on without the turbo, your car will be very very slow.
Hope I helped.

Someone correct me if Im wrong, but I think the WRX oil pan will hit the front swaybar or crossmember.

Well doesnt the turbo need to be fed oil with pressure... if i just drill and tap a fitting into the oil pan the oil wouldnt have pressure to go up into the turbo... I was thinking more along the lines of oil galleys in the heads and tap into those and have the turbo fed off those.

possibly the head having pre drilled oil spots for turbos and just something blocking it on the NA cars...

I am going to be using the wrx oil pan...


Yes i know the car will be veryyyyyyyyy slow without the turbo hooked up... but anything is better than not running at all

you get the oil feed from the galley plug in the block.

and return to the oil pan.

I have a WRX oil pan on my car - there are no fitment issues
