Hi. I was just wondering what the differences were on the engines to make the power difference. Is it just a different ECU or do the import engines have some internal work done to them? Cheers Michael

 

what year?

 

thats a bloody good question

 

from memory..

93~96 are all the same turbo (td05 16g) except the WRX import wagon (td04)..

97~98 the uk has td04 and the import a vf turbo.. depending on model and what they had laying around vf23, 22, 24 etc
99~00 uk is a td04, wrx is also a td04 although seen some WRX saloon with VF on but whether original who knows, sti vf28, p1 vf28 etc..

01 onwards - WRX uk abd import td04, sti have a vf34 or 35 in uk with imports having the twin scroll vf42.. sti forester has the non-twinscroll vf41 if I recall correct.

but in answer to the question the ecu maps are more agreesive also on the import

 

dont uk turbos 98-00 have metal head gaskets too

 

Oh yeah sorry. It'd be 1993-96. So the heads would be the same then?

 

the wrx and uk are the same.. sti have solid lifters, better cams and valves etc

 

is there any more diffenraces between the two for say 2001 cars

 

JGM knows lots of turbos.
