Post by: ChrisW on March 03, 2004, 21:10:02: I've just sold my S3 which had that set-up, it was already in when I bought it so not sure what you would need to do, but yes you can definitely do it.

I'm sure somebody will be along shortly with a few pointers! :wink:

The gearbox is less straightforward as it would then have permanent 4wd which means you should change the front axle for one with CV joints (stage 1 V8 is the only leaf axle with CVs). Relative length of the gearbox may also cause problems with propshaft length.

Then again anything is possible with an oxy-acetylene torch and a big enough hammer :twisted: :twisted:

Post by: ChrisW on March 03, 2004, 21:54:24: ISTR that the 2.5, in simple terms, is just a 2.25 bored out to 2.5 with a bit of modernisation isnt it?

Would it be easier/better to bolt the 2.5 to the exising S3 gearbox or is the box stuffed?

Stage 1 V8 bits like front axles are like the proverbial rocking horse doo-doo arent they? :?

I thought the difference was in the stroke.

Certainly easier. The 2.5 petrol went in my S2 without any problem.

The stage 1 specific parts are AFAIK

If you're interested, I'm breaking my 90 in a few weeks so I've got a 2.5 NAD up for grabs along with all the gubbins, gearbox, transfer box, axle etc etc

Post by: diesel_boy on August 06, 2004, 01:47:47: the 2.5 will go stright in but you might as well put a s2 or s3 box on it lesst messin around and if your up toit put some rang rover 3.5 diffs in there that will sort you out only if you put a 2.5 turbo intercooled jobby in ther ull have to do minor engine mount mods as ive have done both mods to a s3
