3.9 efi conversion series 3 lightweight! exhuast manifold help!!!

hi all, need a small bit off help with my exhuast manifold!!
it is a series 3 light wheight it had a 3.5 v8 in, but i wanted efi so started to put a 3.9 in,
problom came when i came to fit the discovery header pipes they dont fit due to the starter is in the way!! series 3 gearbox and starter
i could use the 3.5 manifold but will have to drill holes for lamba's!! dont really want to do this
dose any one no iff a set off efi header from a diffrent car will fit, engine came out off a discovery!!

first off go introduce yourself, then come back in here and I'll give you the answer

Dr can you help?
I have a strange rash on my...
hold on, wrong forum altogether.

Do you mean starter motor? Why/how would you have a series starter motor on a v8? Do you mean something else?
My 3.9 didnt have lamda sensors in the headers, I had tubular jobs. So just fit the 3.5 manifolds dont worry about it.
Post a picture of what you are talking about as well and some pics of your landy.

will sort some pics out, yes it has the series starter on the 3.9 this involved a small amount off cutting!!! i just did what the person before me did to put the 3.5 in,

You have to cut the bulkhead to install the v8 properly, you will need a RRC starter motor not an SD1 type or any type that has the solonoid underneath as it gets wiped out by the propshaft. You should be wary of the front axle hitting the oil filter on full articulation. Lots of the above get overlooked and as soon as the landy hits the rough stuff things start to fall off and or fail. Get it right once it will be a good conversion.

Manifolds you will need early RRC pipes these are the 4 into 1 opposed to the 4 into 2 into 1 used on 3.9's but they do not hang down nowhere near as far as the EFI ones you can run the pipes next to the x member and to keep them protected as best as possible. You going to have to fabricate an exhaust system or buy a complete unit from steve parker or suchlike. You will need to drill them for lambda sensors and you can buy weld in threaded blanks easy enough.

P6 ones fit, they both have central exits 4-1

To move the lambdas just cut the pipe and re-weld that section in further up, if you remove them you then need to fit resistors somewhere IIRC


Odds are if it had a 3.5 in it the bulkheads already been cut anyway, its only a couple of inches from the footwells
