Engine replacement advice please
« on: 09 July 2021, 21:35:40 »

I have a W reg estate that had the 2.5D engine. The engine has had catastrophic internal damage following oil loss or burn issue. I had always wondered about installing a V8. My understanding was that the engine bay could accommodate as the US version was originally planned around this. Car currently at professional garage belonging to a friend who is able to help with the work, but, would need a plan.
1. Has anyone in the UK attempted this?
2. If so was it accepted by the DVLA?
3. Was there a need to upgrade the diff?
4. Is this a really stupid/dreamer idea and best to replace like for like?

Sorry for the left field questions - thanks in advance for reading.

There are pictures on here somewhere of one members car who installed a V8[one of the LS engines I believe]and supercharger into an estate.I don't know what engineering challenges he faced to get it to fit-not a lot of room left under the bonnet once it was in there-but as I understand it he also used the front subframe of the Monaro.

It can be done.

DVLA and insurance both happy.

You need about 12k of bits to get it done. Including:

LS1, gearbox, diff, Monaro front subframe and suspension, Carlton rear subframe and Monaro rear suspension. Uprated fuel pump and about 100 hours of wiring and the same again of fabrication.

Given your donor, I would be inclined to fit the twin turbo straight six diesel from a later BMW 535d as this will be almost a drop in :y

Thank you both for the advice - the Monaro option I would have loved, but, the cost and labour time is preclusion. Will investigate the BMW option - probably more in keeping with reality and I suppose in keeping with the fact that the drive train was BMW in the first place.
Thanks once again
