Default I need help with a hybrid swap in a 98 leggy!!!

so i have a swap i want to get under way. i have a ej257 and ej205 heads. wrx intake and injectors top mount. turbo. header uppipe downpipe. bov. all i need to put it together is the 2.0 tensioner. but what all do i need to make it run. Emsmap says my factory 22 sensors will give me issues when i get the other motor swapped in. im in the process of buying a wrx wiring harness and ecu. what harness do i need? the whole harness? dash and engine bay harness? what other stuff do i need. i want to get it 95% together before i take it to iag. itl be swapped in with the automatic tranny. so tranny issues and swaps are not an issue. just wiring engine management and tuning. i plan on having iag splice the harness. instal the wrx ecu and dyno tune it. motor being allready built. any and all help would be GREATLY appreciated. thanks.

Pete

Peter: Sell this swap to me... LOL

Anyway... You will need ALOT of wiring work done. You have to merge you Legacy harness with a WRX engine harness for it to work. A big part of the harness will not be needed if you plan on keeping your factory dash and interior. Since your car is OBD2, it will be a little more work. IAG will prolly charge ALOT in labor. My best option for you is to get a dailydriver, bolt the engine up to your 4EAT and take it to IAG to make all of it work. About you keeping your 4EAT, LOL, you better not romp on it or its going to explode lol

4eat shall be fine. swapping a fozzy trans one day after the swap. have a dd already. 92 leggy l. might haul the whole car to iag minus factory harness so they can merge instal and tune that beast. im putting the heads on it soon. i need to contact subaru and get a 2.0 timing tensioner. ebay wiring hanress and ecu one day soon. maybe next week after payday. i was concerned with just putting the built motor in and running it n/a so i can drive it up there. but idk. i need a template on where to notch my subframe. was hoping to have way more input than this but its all good. 02 rex heads and intake with oem injectors. whatever size they are. need a 02 wrx harness and ecu. shouldnt be too difficult seeing as how people cat drive and total cars all day long.
