geoffbeaumont Posted September 24, 2006 Share Posted September 24, 2006 Well, seeing the old V8 is definitely okay as a base for a little project, I've now got to decide what to do with it. I'm not going to rebuild it as a 3.9, even though that would be relatively cheap. Way too much hassle rebuilding it and swopping out the engine just to get back to what I had before. So, what I have in mind is upping the capacity, fitting a high torque cam and hopefully some better heads. I fancy supercharging it, if I can get my hands on a supercharger at a price I can afford Time isn't really an issue - I'm doing the head gaskets on the 3.5 at the moment, and then it should be fine for quite a while - the constraint on this project is going to be money (or lack thereof). It'll be built to run well on LPG, petrol can be just 'limp home' but for reasons of practicality will probably still need to be available. Other considerations are that I'm definitely not, in the short term, going to be able to stretch to upgrading the autobox (standard ZF 4HP22) or any other part of the range rovers transmission. I also want to keep the BW viscous coupling centre diff, because I like it. It would therefore probably be a waste of money to build something capable of destroying the drivetrain as I'm not going to be able to use it to it's full potential. I fancy building a 5.0 stroker, but I suspect going for something more standard like a 4.6 would probably get me a lot more performance per pound. Oh, and the main object of this project is to have some fun and see what we can build, not to create the ultimate no-expense-spared off road racer, so we'll be doing as much of the work ourselves as possible. That said, I've only got very basic workshop facilities (my garage) and I've no illusions I can give John Eales a run for his money... Any advice would be appreciated - for instance: which jobs should I not consider doing myself? what's a reasonable spec to aim for given the above constraints? is large capacity and supercharging pointless/just going to blow up the first time I welly it? could I build an engine that'll be pretty decent normally aspirated and then add a supercharger as and when (if) I can get my hands on one, or does the engine spec need to be too different? And yes, I know I haven't given a budget - because I don't really know what it is yet. Quote Link to comment Share on other sites More sharing options...
