ej20 swap info required

I have an import wrx with a melted piston im thinking of just replacing the full engine I am fairly competant at changing engines i have done many types before
although i have never attempted an impreza yet.
Anyway dont want to rabbit on forever so heres the question
Are the other Ej20 engines the Ej20k and Ej205 a simple swap over as in use the inlet and exhaust manifolds off the Ej20g everything wires up right and the ecu doesnt need to be changed ect. I have been looking on ebay and there seens to be alot of confusion some say 1993-2000 some 1993-1998 then theres 1998-2000 and they are all just listed as Ej20. Can someone please let me know what needs to be done if anything to put each type in my Ej20G WRX thanks....

Re: ej20 swap info required

best bet is to keep the new engine to the spec of the original,compression ratios are different throughout the range thus meaning the ECU won't be able to compensate,thus will end up needing an aftermarket ECU equating to map time etc and increased costing..


spec list for impreza's :- http://www.iwoc.co.uk/impspec2.html

i have found a company called ideal engines they have them in stock refurbished cost about 1300 delivered. also i got quoted around 800 to rebuild the engine thats in it. Maybe i will put the wheels,coilovers,exhaust and front bumper on my uk scoob and scrap the rest. i paid 2 grand for it last week im gutted.

Re: ej20 swap info required

as far as second hand engines go you make get stung, theres alot of dodgy dealers out there.

also 800 for a rebuild is about 2000 less than i'd expect so sounds like a bodge it and scarpa job to me.

Ideal engines are SMR/Mr engine so avoid like the clap.

The 800 quote i got was from AS Performance in birtly. I have only ever heard good things about them. And i am led to belive that they are also sponsors of this very forum.
