Land Rover 110 V8 cast manifolds to Range Rover conversion

Sorry been lurking for a while but now a good way into my 110 V8 (1985) rebuild and improvement. I'd read about moving to Range Rover cast manifolds but never found a post with all the bits photographed. For mine I needed the two cast iron manifolds + two down pipes + Y piece but I also needed to change the gearbox crossmember.

This is the crossmember in showing the gaps each end for the down pipes ...

1988 Defender 90 V8 Petrol CSW Rimini Red

This is a good mod - I connected mine to a TD5 system, much bigger bore and a sensible increase in noise.

Once done it's worth swapping the needles in the carbs for BBW, that gives a huge improvement in drivability.

I'm going for these manifolds, Weber 500 downdraft, MegaJolt with the manifild pressure advance and a temperature sensor choke. I'm also sticking a lambda sensor bung somewhere so we can then do a rolling road final tune once we've run it a bit.

Have you thought about one of the Holley Sniper or FiTech injection systems? 90 V8 CSW - 1988

Looked at going the full fuel injection route but had quite a lot of other "stuff" to get done. I have a Thor manifold and injector rails ready and waiting. At least with the MegaJolt I'm half way there ....

I have a pair of good 3.9/4.2 manifolds with good studs if anyone needs some?

TD5 rear section fits physically but mounts are in the wrong place so I went for new chassis mounts so that I don't have problems with replacing down the line ...

You won't be surprised to hear that mine has some impact damage on those lower exhaust pipes....
