mk1 Hybrid question

[nathanH]

hi all

To hybrid my valver i know i need an F7R bottom end or a complete williams or F7R magane engine. Can i use another renault 2ltr bottom end from a laguna 2.0 8v? or is this completely different, Im thinking it is but just checking the obvious. Would ask on williamsclio, but i cant seem to open an account.

Would i be better using a full Megane F4R 710 engine, than a williams, i know the heads are better for throttle bodys and headwork, but the fact that it has DIS rather than old skool points seems to make more sence.

I will be going along the path of forced induction, but im not at that stage yet, so bearing that i mind. williams and especialy full megane engines seem to either be uber ££££ or like rocking horse shite to find. At the moment the F7P is fine but after the car has been setup and finished i will be wanting some proper power.

thanks

I dont think the F7P bottom end will fit on matey...

The laguna 8v bottom end will not fit, think they can be put on an RSi head but definately not on a 16v head. Apparently the megane head is supposed to be a bit better as you say, but to run it you would need to have the head machined to run a dizzy cap in order to use a williams ECU. If you wanted to use the megane set up without the dizzy it's a pain in the arse and I've only ever seen one hybrid running that set up so would not suggest it at all.

could i not run the whole megane set up i.e engine and Ecu aswell?

It is possible, but there are a number of complications I believe. I don't know much about the electrical side of things though tbh so I'll leave explaining it to someone else. Try asking over on retro-renault.co.uk as chris_h on there will be able to explain. As I say though everytime I've seen anyone ask about it they have been told it's much, much easier to use the williams head/ecu or have the megane one machined.
