are 2007 manifolds soutable for older V8's?

Post by Ralphh85 »

im gonna have to do something to bring my exhausts along the exhaust ports then down amnd under the car due to room isues, would these fit older 3.5 engines?

they are very ugly but might do the trick?

they dont look like RV8 manifolds to me - flange holes are in the wrong orientation aren't they? More like the BMW ones?

Definitely not for the original Rover engine they are probably for the 4.2L Jaguar V8 engined version.

if you're stuck for space you could try some MGB V8 manifolds, they hug the block pretty tight and I think are better than the standard Rover ones.

I've probably got a pair of rear exiting manifolds somewhere. I think there were single and twin pipe rear exit manifolds offered at one time or another, which do you need?

These look ideal..
They are 101 exhausts. (so they are OK).

101 exhausts may well be the way forward.

will have to check engine/subframe an might have a bid on they!

cheers.

101 exhaust manifolds have a nasty habit of cracking, so i'd check first to make sure they haven't. Also the right hand (IIRC) manifolds are getting very rare these days and can go for big money.

101 exhausts

Post by Ralphh85 »

where do they crack?

i have 1 already which i picked up from a mates last night, its the left hand side one (drivers side).

im not sure if he has any more as he wasnt there an was only one i could find.


Ralph

edit, i will probly replace them with tubular stainless ones once ont he road anyway so as long as they are ok for a bit it will be fine, if they crack in a year it doesnt matter.

also they are a prettty bad performance design, will they reduce power at all? or are they no worse than rangy ones etc?

Mine had a verticle crack on the engine side ~half way along. I didn't see it until i had the engine stripped for a rebuild.
Apparantly they tend to crack because when Land Rover produced them they didn't let them weather for any length of time before they were machined flat. Also, they were attached without any gaskets which probably didn't help either.

101 definitely weren't built for performance! I think the Range rover P38 exhaust manifolds would be better (and usually cheaper). unfortunately for me, they foul on the 101 chassis.
