I would just chuck it in there TBH, I put a full
TBE and PW TMIC and drove it around for 3 months before i got time to drop it off for a tune and turbo....
For all the haters out there, just for the record, f@#k all happened and the engine is still living!
OMG no, it can't be true can it? but a Subaru engine is the most critical thing on earth la la la....
Edit: forgot to mention that i also put EL headers on and a cossi filter.....
