Hi everyone,

This is my first post as i have just got myself a scooby after a short time away from having one (2 years) and just stepped straight into a problem, i think i have a head gasket gone and was wondering if anyone knows if i would have any problems putting a '95 wrx engine into my '99 uk wagon as i have the engine out of my old scooby which i know is ok.
I was also wondering if the turbo from the wrx will fit and if there would be any difference in power output.

Thanks for your help!

 

A 95 engine is a phase 1, a 99 engine is a phase 2, its not a straight swap, and your better off just getting the head gasket repaired rather than buying a 2nd hand engine with no history.

Thanks for the reply the engine that i have is out of my old car so i know a lot of its history but there is always a risk i suppose, I take it if the engine is different not much else will transfer over?

 

It's the wiring loom and sensors, AFAIK.

 

if i stripped the engine down to bare engine will the sensors and wiring loom from my '99 not fit it then?

 

No. Even forgetting about internal mechanical incompatibilities (I think the cam profiles changed between 95 and 99 for example, and the compression ratio may be different too), the 99MY inlet manifold won't fit the 95MY engine. Because of that, you can't use the '99 injectors or loom either.

As Tony says, if you think you have a leaking HG on the new engine, by far the easiest option would be to get that addressed. Every other possible way forward in which you go out of your way to use the old lump causes more hassle and is less likely to leave you with a properly functioning car.

 

my mate fired a 2003 wrx engine and gearbox in my 2001 classic sport then we got it up to 300bhp not one problem thats the one in the picture dont have it anymore lol but never had any problems with it, but he transfered everything basically stripped the 2003 and swapped everything over, but im not a mechanic and dont pretend to know much cause i dont, just thought i would add that lol

 

Thanks to everyone who replied it was a great help much appreciated, looks like i will be buying a repair manual next lol
