Hi All,

If you've done a V8 conversion can you let me know what exhaust manifolds did you use....

Thanks

3.5 manifolds fit ok. I've got 3.9s and I had to raise the engine to get the nearside one to clear the chassis. Other people have just raise the nearside engine mount so twisting the engine over.

Alright mate,

been a while since I have been on here, still having trouble with manifolds? Im in the same boat really, I have left doing the manifolds for the time being tho. I have got the original cast ones to fit, I know they are pants but it will get it road worthy for the time being.
I have tried to get the ss range rover sport manifolds to fit, now depending on if you have modded you bulkhead yet you ( may ) be able to make these fit with a few changes. tho I havent yet seen it done. The reason I couldnt is because i had already mounted and painted my bulkhead after using TVR exhasts as a template.

OK so my conclusions to this is, I will need a custom set of manifolds.... :doh:.... yes i know £££££... but, one of the biggest performance improvements to this engine is in the design of the the manifols and exhaust system. so for the time being im saving the pennies and getting on with the rest of my build.

few pics.

cast manifolds in place, its tight....

TVR manifolds... will need adapting....

P.s. sorry for not pm'ing you back i do have a tendancy to forget,

I do remeber in the end tho

Lets us know how you get on.

Cheers

Ryan

Oh - tuning is mostly in inlet and heads till about 220 - if you match and port cast heads - do a search for G33 rover V8 tuning
