Default Difference between uk and import engine spec?

Hi folks
Can someone tell me what the difference is between the engine spec of a 95 wrx import and a uk car of the same year?
Are the turbo's the same spec etc??
Cheers Jules...

Classic WRX's have same engine as UK. The STI has the different internals.

Thanks for that the other fella had me worried!

What about the turbo and injectors are they the same?

I'm guessing the import wrx has a diifferent map to the uk car?

Cheers Jules...

Youe ecu is a z4 which is a different map as it is rated at 260ps (256bhp) whereas the early UK were only 208bhp.

iirc the turbo and injectors are the same as a UK car for the 95 (td05 turbo and 380cc injectors)

I thought the TD04 would have been fitted to the 95 uk car? Might be wrong though.

Just out of curiousity, why do you want to know what the differences are?

Are you buying a car or modding an existing car?

Hi
I have one of each and although the UK car is a better more original car the import is more lively. I'm trying to decide whether to tune the uk model or tidy-up the import hence the questions above.
The other major gripe with the UK car is the nasty tweed trim which will have to be swopped with recaro style should i keep it.
Cheers Jules...

Whilst i have your attention fella's
The import has a boost gauge fitted and peaks at around 0.8 bar. Is this a standard level of boost for that car?
Cheers Jules...

I think that 0.8 - 0.9 is about right for the boost level.

Thanks for the info.
So am i right in saying that the only reason for the power difference between the 2 models are the map/boost level then?
I have no idea what boost level the uk car is as there is no gauge fitted but it will be standard as is the rest of the car.
Cheers Jules..

AFAIK the difference between (non STi) classic imports and UK cars is in the ancillaries, not the engine build itself. To put it another way, any UK Turbo is just as capable of making good power with the right supporting mods, as an import WRX.

So basically, get the fuelling, the turbo and the mapping all correct and you will get the same results whichever is your base car.
