Will a jap classic WRX engine fit my uk spec turbo 2000? Will I need a different ecu/loom? Or is it just plug n play? I ask this as the heads have warped on my existing engine and have been quoted like £850 to have the heads took off and skimmed etc so I don't think it's worth having the work done as it's already had a bottom end rebuild what you guys think?

 

What year is your car?

 

Sorry, my car is W Reg 2000 mate. Dunno what to do with it as it only ran well for a bloody month it's I got it at the start of October and it died on Halloween and it's been off the road since! I'm annoyed cos am already 3.5k in debt for it as it is...

 

yes it should be a straight swap but remember that the jap spec compression ratio is 8.5:1 whereas the uk spec is 8.0:1 so you may be running the risk of detonation if you dont get it mapped. just remember that if you run higher boost pressures the idea is that you also run a lower comp ratio to accomodate the extra cyclinder pressures.

 

So it'll work with my standard uk ecu?

 

So just to clarify, I have to get an engine out of a facelift impreza WRX?

 

I will be able to get hold of a complete car fo £800 the cars an M Reg will I be able to use the engine and other bits??

 

No, in a word. If you get a 99/00 you will be able to use the complete engine, with the caveats Rich has already mentioned. Anything earlier than an MY99 is a no-no if you want a straight-ish swap.

Given you appear to be on a budget you'd be better off avoiding engines out of an import too, as with one of those you effectively need to add around £600 to the bill for an immediate custom map.

If your engine's shagged and you're looking for a cheapish replacement, the simplest option is another out of an MY99/00 UK car, or, if push comes to shove, a long engine out of a bugeye or blobeye UK WRX.

 

Cheers splitpin, do you think it would be worth just gettin my heads skimmed etc?

 

If the bottom end has already been rebuilt and you are confident its a good job i would get the heads skimmed rather than risk buying another unkown engine.
