best engine

[KEVLA]

hi everyone , newbe online, i was wondering which engine choice gives the best performance, i have been looking at using rv8 with the lt77 box just because of the wonderful v8 sound but how does that compare with other engine choices for speed..... kev

Thats a question that could be answered with a hundred right answers. Depends what floats your boat and what you want the car for. Get ready for the avalanche.

V8 a good engine with good torque but a bit old, the duratec is lighter and can give more bhp
However it realy is what floats your boat
Big V8 to little bike engine they all work well but in a different way.
Me I like a high reving straight 4 car engine

I love my 6's but I gave up trying to make one work in the space (mainly height ) constraints.

I am currently building with a 1.8 CVH, with the intention of converting to Zetec after IVA.

Torque is not a big requirement in a light car like the Roadster, hence bike engines are very popular with their High power output.

The rover is quite a large unit, there are more compact 8's out there if you want to go that route.

If you want the ultimate v8 for a seven it has to be the tvr melling ajp engine.It is 10 kg lighter than a zetec anything between 375/450 hp depending on the state of tune, comes complete with throttle bodies, it is the smallest lightest v8 I have ever come across. Can be picked up for as little as 2k with a t5 gearbox. Fits in the engine bay with ease < no bumps in the bodywork needed, I recently missed one on ebay complete with gearbox and ecu for £1750. You could spend more than that tuning a rover lump.
