TVR Tuscan engine questions
Discussion
Hi everyone,
im keen to hear what exactly fails on the speed 6 engines. Lots of them have had rebuilds, but what is it that fails? is it the timing chain affecting valve gear or oil starvation issues?
Does anybody know?
TVR specialists seem vague with giving away info for some reason, but i want to know. Saying it needs a rebuild isnt good enough for me.
Thanks for any help!

OK, I am not the oracle on this subject, but I think I have sufficient knowledge to help you here.
Basically, in most of the earlier Sp 6 Tuscan engines, items like valves, finger followers, ½ time bearing, Valve guides, and associated components, some had the consistency of hard boiled chocolate!
After about 2004/5, these components were greatly improved.
That’s not to say some earlier cars were sound, it’s a better bet that later cars were.
Also, the Sp6 Engine, is pretty much a race spec engine, so needs warming up correctly, with a mechanically sympathetic approach. If this is done correctly, then maximum welly is fine, the rewards, plenty.
It is a great engine, and needs to be built correctly. With the above relevant parts upgraded to the correct specification, it is long lasting as well.
My advice would be, if you can buy one that has had a reputable firm rebuild, such as TVR power, or Str8six, Go for it, especially as the warranties with these companies are very good.
This is not to say, one without a rebuild will be fine, just that one with is more a dead cert!
When this Car is “on song” it is an awesome road car, especially if you get a 4.3, with 400Lbs of torque in 1100kgs!
IMO, the Tuscan will be a huge classic one day, if not already. That’s not to say most TVR’s aren’t already, but the Tuscan, IMO, has it all!
