Impreza engine swaps

[SeeSubyRun]

I'm wondering if i were to get a older model AWD Impreza, could i buy a EJ25 or EJ20t or even something STI related engine and would it bolt right into the mounts? Or would it cost too much for customizing and be better off buying the wrx or 2.5rs? Also is there such a thing as an old wrx or sti engine with a six speed trans. These are the sugarplums I dream about. Hehe.

Scoobies have a high interchangability rate. Having said that I think the link below would answer your questions alot better than I.

=) Good luck

i just bought a 94 front wd impreza 1.8 and i was wondering the same thing. From what most people have said in this and other forums is that the ej engines will go into any mounts or trannys that other ej engines come with. from what ive heard though, you will have a problem with crossmembers but those are not even that big of a deal.

All you need to do for the cross member is one of two things cut and weld it to fit right (not really recommended , but can be done) or by the legacy cross member and that bolts right up.
we did the ej20 det swap in our 2000 impreza we are currently running 290 horse power.
let me know if you need any help or have further questions.

I want to do a similar swap just want to clear something up, the subaru engine you are talking about is ej20t I believe, the letters det were used by nissan ie: sr20det.

most nissan end in det unless there N/A.

The crossmember is just the small part of the swap.

The biggest hassel is the wiring harness I've done a few swapps so let me know if any one needs help.

Hey man, were the swaps worth it? I mean, I got the engine and now Im kinda backing off. I dont know how much more money its going to take. Although little by little me and my roomates are filling the garage with good tools, coming soon: welder, so we can do most of the stuff ourselves. I dont know how much more money will be spent. How much did you spend per swap. Thanks for the help!

Mechanically, a subaru is a pretty easy swap. wiring...is on the verge of nightmare. especially if you opt to do it the 'right' way and rewire all the underdash harnesses.

[stageonetune]

Hey Leo. If the wiring is done right, than it is worth the effort. It usually takes about 24 to 40 houres of work just in the wiring depending if u have a GC8 or a GDA and what year the motor and harness is.


I've worked for subaru in Japan for a few years and race my GC8 in Japan and in us so I've been around the block on subarus for awhile so let me know of any questions u may have.

thanks Gen. right now Im working on my civic, once thats done I will start working with the subaru engine, although to tell you the truth the original reason I bought it was to swap it into an 86 VW Vanagon. I have the vanagon too but for a while I thought I should do an older impreza instead. I dont know much if nothing about subaru's and thats why Im kinda thinking hard about it. But Im gonna put your name in my buddy list in case I do decide to do it I will get in contact with you for any help I need. Thanks again.

I inherited my father's Subaru and the motor is pretty beat and not to mention SLOW!!!!So I wanted to know about doing a swap in it. How hard it is to swap in an ej20t into a 93 Subaru impreza L, and how much would the total swap cost. I heard it is a wiring nightmare. Would I have to change out the drivetrain for this swap. Can anyone provide some insight on this particular subject. I would appreciate info from someone who has actually done it. But all info will be helpful.

[vtecpower220]

the motor in it now is a ej18 (1.8L AWD)
