2.5i turbo build plans

Not sure if you're too far in the build to go with the following option, but may help others.

 

Rather than use an up pipe to mount the turbo in the classic location, should buy a stock 5th gen header and turbo (low mount).

 

Anyway this means you'd have no up-pipe and rather than a down pipe you would have a J-pipe. So much more simple.

That way you have the efficiency of a low mount location (great spool) and also not have to worry about cutting the cross member .

 

This would likely involve using the Gen V legaxy GT sump because it is smaller so it clears the headers.

 

Other benifit would be that the intercooler piping would be quite short if pairing this with a FMIC.

 

Finally I should mention that I will be testing a 2015+ WRX header and turbo (mgt2259s) on my ej25 gen v . If it bolts up, this would be another option for those wanting to turbocharge an NA ej25 for cheap (my header and WRX low mount turbo cost $400 aud delivered with only 8000km on it). I picked up a complete 2015 + J-pipe and complete stock exhaust for $100.

I’m interested to see your test results.. that would be an easy option!

I have all of my parts already, so it’s not something that I’ll be trying..but I will definitely spread the word if it is a viable option.

Thanks!

Part 2 is up! In this episode, we tackle installing the air-to-water intercooler.

The turbo UP dumps directly at the N/A X-member, have you notched it yet?

Nice clean install btw

Thanks! We do have a LGT crossmember to swap in this coming weekend!

I believe they will purchase the x-member from a GT to swap in.

Bingo!!

Stock Subaru BPV modified and mounted to the AWIC!

PART 3!!

I apologize for the delay.. I got lazy/unmotivated/busy/etc..

This one isn't too exciting, just making some changes to allow the turbo inlet fitment, and turbo oil feed plumbing.
