WHY HAS TVR GONE FROM 4.0 TO 3.6 IS IT RELIABILITY

[demonseed]

ARE THE ALL NEW 3.6 TUSCANS DESIGNED TO BE MORE RELIABLE THAN THE OLD 4.0?
DO YOU RECKON BY DOING THIS WE WILL NEED LESS REBUILDS, AND ENJOY MORE MOTORING?

Having just purchased a Tuscan I asked the same question of the Dealer.
I was told that the new Tuscans were 3.6L for two reasons:
1. To help engine in production by reducing the number of variants.
2. To give a greater differential between the Tuscan and Tuscan S.
No mention of reliability was made.

Unfortunately not. My 3.6 was rebuilt at 4100 miles and I know of other 3.6's which have had rebuilds.

Ouch.! Sorry to hear this..

I've got a 18 month old 4.0 which is still going very strong without rebulid.. I'm convinced it's nothing to do with engine size, running in etc as there doesn't seem to be any consistancy.

[demonseed]

BLOODY HELL!!! WHATS A REBUILD COST AND HOW LONG IT TAKE???

[apache]

Stop shouting DS! I have heard that 3.6 is the optimum size for the S6 engine......I don't spose that helps though

[demonseed]

Sorry forgot i had the caps on! i thought the 3.6 tuscans came out this year in march????

The rebuild took 6 weeks
But was covered under the warranty.

The 3.6 has been out a while now. Mine’s an August 2002 car which I bought as an ex-demo last November with 2200 miles on the clock. The engine has been a lot smoother since the rebuild and goes really well – having driven both 4.0’s and 3.6’s when choosing a car, I think the 3.6 is definitely a smoother drive.

Except it’s now decided to start pinking at high RPM……

Hmmm pinking eh!! get yourself some Millers Octane +, i swear by it in my STI Scooby matched with Optimax im running 100.50 octane, Loverlyyyyy! Demontweeks stock it, used it for 3 years on every fill up!!! sweet as a nut, so tried and tested id say

I’ve thought about trying that. But the dealer’s mechanic doesn’t think it is a fuel issue. They think it’s possibly a legacy of the rebuild which may need a different ECU chip to cure. Currently waiting for a response from the factory about it.

Another reason is marketing...and broadening the range.

ie why buy a 4.0 l tuscan s, when a 4.0 l tuscan is available.

So the cheaper models might be distinguished by the base 3.6, 'performance' i.e S models, will have the 4.0L (or is it 3.9 now?), etc,etc

In Actuallity the engine capacity may be the same base engine, but different tuning and badgeing.

I can imagine there is already a bit of a clamour from the diehard petrol heads (a smaller, but not insignificant number of TVR owners buyers, for an S version of the T350C.....

Actually why is it the T350C when it has got a 3.6 engine.....

Car names really screw you up some times.!!!

BHP...?

what does pinking mean?

[roop]

Pre-detonantion. The fuel mixture in the cylinder ignites and combusts early due to a low octane rating or timing that is too advanced. Causes 'pink! pink!' noises to come from the car and generally knackers the engine quicker. Sounds a bit like piston slap sometimes.

Obvious really...

Is that a TVR BHP?
