Looking at putting a more powerful engine in as standard , think the American v8's will be to heavy so looking at euro v8's . Audi or BMW ...
Has anyone done this conversion ?

Hi there, i asked the same question to lots of people and they all told me that the V is too wide to fit between the Chassis. Best check for yourself, it would
be the logical choice.

A few idle thoughts -
Jaguar V8 - nice - but not sure anyone has cracked the fuelling when attached to a manual transmission. Very compact power though. Aston V8 - see above - hand built version - best feature is name Aston Mantula ! AJPV8 - Upset everyone by installing one of Trevor's wonders in your car - I don't think the flat plane crank sounds as nice as the normal V8, and parts problems may loom. Lotus V8 - no idea where you get one, or if they exist without twin Turbos - too expensive BMW V8 - never thought of this - think Morgans use them - higher revving could mean you can/should change to lower diff ratio Rover V8 - Speak to John Eales of J.E. Dveleopments - this man is a legend with the Rover V8 and will make you exactly what you need - and it will cost a few bob Rover V8 - JEE - a John Eales spin-off as far as I can tell - exciting engines - but not bespoke. Chevvy Smallblock - tight fit by all accounts - requires sawing and welding and more. My Marcos has a JEE Clubmans engine in flat tune - 4.5 litre - 254 bhp and gentle soft power - will pull away in 2nd and lope along all day in top. If you tune the pants off the engine you can get well into the 300 bhps, but it will be nasty to drive - more of a race car. Which is fine if you are only racing. I do keep looking for other alternatives that will sound as loverly - but none so far - and I also found that the MOT seems to go on the age of the engine. So a new tech engine (like the BMW V8) in an old car might need cats, and real strict emission testing - watch for this. Speak to your local MOT man - as it would be mightly sad to discover this after doing all the work. I think it is amazing that you can go to JEE, and buy a 5.0 litre 280bhp engine to slot right in JEE - but will your gearbox take it ? Presumably with the BMW you are thinking of matching gearbox as well ? Steve
There's a lot of talk these days about green transport. Well, I am ahead of the game, I already have green transport ... British racing green.

I recently collected a ex T*R short block cross bolted 5.0 from V8 Developments, worth giving them a try, i will let you know if the gearbox can cope in due
course, (obviously going for the stage 3 heads and suitable cam to match etc) it's gonna fly..........

I have seen LM race cars for sale with BMW M5 engines and 6-spd gearboxes. Very appealing to have 500 reliable bhp and a gearbox that could cope. Not sure
whether a Mantula could cope with the power though, I struggle with my 350bhp odd...

What I have seen of the LM's is they aint a lot different to a Mantula/Mantara so horse power handling is either there or its not. I'll let you know one day when I get my un stressed 350 bhp Chevy on the road.
