3 octane shouldnt make that much difference should it? ive ran 91 in a pinch and i still make good boost(rated for 98 in japan), ill admit ive never had a problem with 94 though. If not boosting that sounds like a fault in the system. a loose clamp, faulty wastegate.... perhaps spring pressure is only 5 psi? by the looks of the system you are completly catless so there is no restriction. Narrows down the problem a bit.. is it stock turbo, ecu, piping, intercooler, wastegate, BOV?
Its the direct reason why mine went into limp mode. Used 91, limp. Back to 94, no limp.
Never knew that it could make that much difference. That is very good to know.The new FA20DIT Forester XT's can be ran with 87 or 91 with no negative side effects except loss of power. Im not going to say they are designed for it but they are mapped to allow it. Kinda cool
Octane ratings in Japan are different than in North America. They use RON we use AKI.Basically AKI is equal to about 0.95 of the RON number.So your 98 RON car should be running approximately 93 AKI. So you are right where you ahould be running 94 AKI from Husky.Pretty confusing that an octane rating is not equal.
Wow Colin, that's going to be a pretty nice winter beater! Great work cleaning it up. While you have it apart, clean up the grounds, and check that the ecm is grounded properly. Maybe look into that switch and circuit for the valet mode or whatever that is on the Revtronix, that could be what's limiting boost. I'd even check that the chip hasn't come loose. Revtronix isn't around anymore, but there may still be some info on legacycentral.
I did some chatting around today... Do you have a 2.2L in this?Sent from my iPhone using Tapatalk
I'll have to check that, seems unlikely that the chip would come loose. but the grounds are definitely a possibility. And yes, it's the EJ22T!
The EJ22T never had an intercooler. It was originally designed for the Rally world but didnt make it to Colin McRae because of the 2.0 engine size restriction.The cool thing is this in the EJ22T and EJ20 of that era(89-93) is that they are the only engines produced to have piston oil squirters. There is a tech at subaru who has done some minor work and is making 360 HP out of his
Nice work any idea twin turbo engine from 1997 or 98 with with fit in 1993 or 1994 4 doors sedan legacy
