So, in my quest for ever more mid-range torque, I’ve come to a couple of conclusions regarding my early ej22.
1- I can cobble together a turbo kit for this with stuff I have sitting around. It’ll sound cool, probably be pretty torquey, but reliability will become an issue. Not ideal.
2- I can frankenmotor this thing. Not a perfect solution either, as it’s still a shade tree hacky sort of solution, and it seems like the power is higher up in the revs for these too. I need torque in the middle!
3- I can swap in a later, more powerful dual port engine and harness, reusing all of the hardware currently on this thing.
3 seems like the best solution, but for the fact that I bought this with the swap, and all of the guides for wiring are for adapting a stock harness to a subaru, not for updating the Subaru setup.
Has anyone done this? Can you provide me some guidance, and prevent me from turbocharging my current setup? _________________ 1986 Syncro westfauxlia EJ22

the only thing you may have to change other then the harness is the exhaust (single port vs dual)
i'd go 2.5 with a set of cams. would be the most bang for the buck
i built my 70 deluxe with a frankenmotor and cams. pulls like a ox on meth. but, it was a pain to build. heads CC'd to drop compression, custom head gaskets etc and it's running the 2.2 management which is fine, except for the million dollar coolant fed IAC valve.
i think you'd be money ahead with the 2.5 and some cams. _________________

Thanks for the correction. I used to be a nice guy, then I ruined it by exposing myself to the public. |
