Taimar chassis mods to take rover V8, any info?

[hallsie]

Hi all

I awoke at around 3 .20 this morning with a single thought that wouldnt leave, but thats another story!
I then thought, Ive got a V8 available and ready to go, and rather than rebuild the old Essex V6, Ill put that in the Taimar instead!

A couple of questions have now also entered the thought process in the cold, very cold, light of day.

1, what chassis mods will I need to do for engine mounts?

2, will the 4 speed gearbox fit or will I need a 5 speed box from a V8 for it?

3, has anyone got any pictures of the upgrades they have done to help take the V8 into the chassis?

$, Am I missing something, or does this seem a very simple process?

Ive ggot the chassis at the fabrictors at the moment, so making something wouldnt be the end of the world!

Thanks

Hi,

The biggest single problem is exhaust manifolds.

I did this conversion on a 2500M in the 90's, and got so frustrated by the manifold problem that at one stage I cut off the modified engine mounts, rewelded the originals & bought a TR6 engine to put back in!

But like you I thought the conversion was worth it, so I persevered, started again and did it. There was about 50mm between the exhaust port and the chassis, to get a flange and a pipe in! An engine steady bar was fitted to stop it rocking and hitting the chassis. I got a bike specialist to make the manifolds in stainless and coupled that to a 2'' exhaust system from JPE.

The only other real problem was the chassis rail across the front of the engine bay, which would foul the water pump. I cut that out after welding in bracing pieces, and made a modified bolt in one.

I used the 5 speed Rover gearbox, and a 4 barrel carb. It was a very worthwhile conversion, but I sold it after a couple of years to buy a 3000S.


The car NTB261K has been featured several times in Sprint and is still around, I last saw it at Classic Le Mans in '12.

I have a V8M but bought it ready converted.

Reply above covers the main issues.

Minimum chassis mods -
Cross member to clear water pump (I think the 3.9 pump may fit without mod),
New brackets to take std. RV8 mounts,
New brackets to take std RV8 gearbox cross member.
Shortened Rover propshaft.
Rover 5 speed box on std. Rover bell housing
'Std' Wedge type gearchange extension.
Maniflow have just made new manifolds for me - they may have the pattern.

Happy to provide some pics and more detail when home.

Thanks David

A few pics of the manifold and water pump area would be good please?
and if you can get one of the gearbox cross member then that would help too.
