Speed Six Engine Variants

[Englishman]

I know some TVR models were marketed with Red Rose and S packages that supposedly included engine upgrades.

Does anyone have any details of these upgrades (just to the engine), e.g. bigger injectors.

Much appreciated.

All very interesting.

Looking at the TVR Parts website, they do indeed offer two types of OE injectors (higher flow just for Tuscan S and Sagaris), but only one crankshaft and one pair of OE camshafts.

I guess any other power/torque increase for Red Rose and S variants must therefore have been obtained by mapping, assuming they were not just marketing exercises.

Has anyone had a Red Rose rebuild and can detail the differences to the standard engine?

That will be very interesting. There seem to be many myths over what an S6 Red Rose engine build actually comprised of.

It certainly seems the S varient of the Tuscan simply has bigger injectors, different cam timing and map - the same as the Sagaris.
