Range Rover / defender v8


Recommended Posts

First of all hi guys I'm new to the forum I have been involved in off roading for several years now using a Suzuki king quad 700 while out riding one afternoon I came across a chap in heavily modded defender v8 after watching him roar up the trails in it I was hooked I set out to find one and came across the lr I have now it's a 1995 Range Rover 3.9 v8 its heavily modified also it has been chopped down and has a defender truck cab on the chassis massive Insa special tracks its been lifted has twin battery's marine fuel tanks and its bright orange it's awesome lol I'm totally hooked on it as I said earlier i bought it as unfinished project only small jobs to do at some point the efi setup has been removed and su carbs fitted it idles fine etc just lacking in power what is best option for me stick with carb ie get new carb if so what's best or refit efi hopefully someone here can point me in the right direction thanks Gary

The V8 had carbs as standard on the 3.5 so if they have used all those parts, which would be the easiest way, then it probably just needs the jets altering for the bigger cc or tuning. Check the carbs are clean and free moving and have oil in them. Check the timing and of the engine and ignition and try something like a colour tune to see what the mixture is.

What size carb are they? Burlens sell all the jets and parts for su carbs.

Have no idea on size the truck is in a friends garage who is a Land Rover specialist I will have him check he recommended I put a Webber four barrel carb on and it will go a lot better pretty dear option tho imo thanks for info on parts for Su would be much cheaper to put bigger jets needles etc than forking out for new carb kit can anyone point me in direction also for mega squirt have been doing some research and think it's way to go for making the v8 more reliable when in water who is the guy to see for purchasing Ms

Yeh it's road registerd just needs mot and tax I really won't have it otr much if at all tbh it's just a toy wee update truck has had a thorough going over and nut and bolt check few small oil leaks fixed I discussed the carb and efi with my mate and I had to go away for work returned today to a Webber carb somewhere the lines got blurred between me and my mate lol so am in two minds to send it back but if it's terrible off road it obv has to go back My local pay and play site has a lot of steep hills and inclines and rivers etc to tackle he's saying to put carb on because of the simplicity

Could you not fit both carbs at the same time to cover it ? ;-)

Then it'd conk out at all angles. Considering my Weber 500 was brand-new jetted correctly for the engine etc. etc. the fact that a £50 3rd hand flapper EFI system out-performed it in every way (on the wrong engine, flapper was from 3.5) says something.

if you want a V8 off-road and aren't a total technophobe I'd strongly vote megasquirt-v8, it's more effort to fit but just so much better.
