thinkng of a td05 turbo to replace my tdo4. i'v had one before on me old engie but it let go and so i bought another engine, hence the up grade,
how ever i'm till using my z4 ecu would it be ok for a straight swap or would i have to look in to it further?

 

Z4 is a jap wrx ecu isnt it. And the jap wrx's had tdo5's on anyway.

 

What car does the OP have? (year/model please, my crystal ***** are not working today )

Tony

 

ooppss soorry its a 1994/1995 wrx jap import but the engine is unknown at the mo as it luks the same other than the smaller turbo and the lightened cam pully wheels rather than the solid looking ones on me old engine.
hopes this helps with your crystal ball tony lol

 

Is your car a saloon or wagon? early wrx wagons came with the td04 and less bhp, early wrx saloons came with the td05, amazingly early uk wagons had the td05's, dont ask why

Tony

 

Don't think the Z4 was fitted to wagons. I believe the Z4 already expects a TD05 so fitting one shouldn't cause a problem.

 

its a saloon pal. right so in theory it shud all be fine and danndy but with a little more poke.
thanks guys

 

i have a 96 wrx with the td05 16g and z4 as standard it runs 260 standard

 

well i'm hoping i can get to that poss more with the light mod's i'v done.
my old engine was 261 and that as standared but it didn't like been driven at very high speed for very long hence why i had to get the one i got now. just a shame i craked me housing on me old turbo.
thanks for ur help guys just got to sweet talk the gf since she's my bank at the mo lmao
