What's involved with getting a series 5 turbo engine in a series 4. Is there any restriction in regards to the engine bay and the mount points between the 2 models?

 

Gidday,
well that's what I've got Mine was an auto so a new crossmember was needed to mount the manual gearbox, but apart from that it should go straight in. You may need to use a series 4 turbo front cover so you use the mechanical oil metering pump instead of the series 5's electric one. Mine was even using the N/A computer for a while (which I don't recommend, but it did run well at low boost), I've since ditched it though.
Mat.

 

IF you are swapping an S5 in your car then you need all the S5 parts: engine everything that comes with the engine wiring harness ecu and the guage cluster wouldnt hurt thats the plain dumb simple look at it
