Chimera - Range Rover P38 engine swap
Discussion
Hi,
I have a very straight and tidy but unexciting Range Rover P38 4.0SE.
I have an option on a TVR Chimera which has been crashed.
I have time!
These are both Rover V8's, the gear boxes will match, checked this. The electricals are an issue due to the immobiliser and integrated ECU but the result would be awesome, a bit of sleeper and usefully quicker than the 4.6HSE.
I reckon the TVR's 300bhp will not cause any massive transmission issues as the Range Rover runs 200bhp and I am only going to use it on the road, it was designed for much more rigorous use.
Has anyone heard of this being done, if so any snags or pitfalls?
Cheers.

Lots of TIV engines have gone into Classics and P38s so it is perfectly doable. There are probably some obvious hurdles which Google will find for you.- Disclaimer

Re the engine, something to bare in mind is that you might not actually get much better performance as the engines for the two cars are built differently to do a different job.
With the P38 (auto?) the engines are designed for torque in exchange for bhp and for this to be delivered in a low, wide band, whereas the RV8s built for sports cars are designed to rev higher, have higher bhp and less torque where a big heavy auto needs it.
I would spend some time researching that aspect as you could end up with something that just doesn't work any better than the stock P38 engine once mated to the ZF24.

I think some research may be required... :-)
I would go after market ECU and a Turbo Kit , Wilder cam, job done. 
I have a 4.0 se as well it is a little gutless but it is 2.8 ton of car so it will go never like a chim. It's just a cruiser i guess but if need must to fettle, needs must

Starting to think about this myself as now have a spare 5.0 engine. I was thinking of running this with Lucas gear out the Chim seeing as I am going aftermarket ECU for the Chimaera.
My P38 is running later LR electronics so just need to find out what else the ECU gets involved with (tachometer, auto box? ) and figure out if emissions will be an issue.
300 bhp and gobs of torque would make it an awesome motor.
