Genuine question for the 160bhp gurus

Seriously? Are you guys the ones doing 90mph on the dual carriageway in the mornings to get to work quicker? (don't answer that by the way).

A 115 diesel is quite capable of not needing to change down for hills - it's got plenty of torque still. Neither are there any more gear changes required than in a 160 (same number of gears): you may even argue less changes as you won't get into top gear so often. You'll still be in top gear by cruising speed though. The effort - that is all the car's, all you have to do is sit back and relax, just put your foot down further.

Dangerous ? No.
Boring? yes. (for me anyway)

Now just be honest and say a 115 is boring to drive within it's limits, ok?

And just to put some figures on the table - from Parker's.

Here's some 0-60 times: remember these are achieved drag race style - something you won't do yourself in your own car more than once in a blue moon. (all manuals - auto's don't count in performance ) (and all saloonsj - tourers......)

2.0 CDT (114) 11.0 sec top speed 120mph

1.8 (118) 10.9 sec (0.9% faster) top speed +1mph
2.0 CDT (131) 10.6 sec (3.6% faster) top speed +0mph
2.0v6 (147) 9.6 sec (12.7% faster) +7mph
1.8T(147) 9.1 sec (17.27% faster) +10mph
2.5v6(174) 8.2 sec (25.45% faster) +17mph

Having driven a 131, 147 v6 and 1.8T and a '160' diesel. I felt that the 1.8T was closest in performance to the '160' (albeit the delivery is quite different). All the above will cruise on the motorway at normal motorway speeds in top gear without needing to change down. (equal effort, equal gear changes). It wouldn't save me a second on my daily 26 mile dual carriageway commute (7 roundabouts) to be in the 2.5v6(174) over the 2.0CDT(114). As far as I know all have the same brakes - and there's less weight difference between the models than you might think.

A modern passat 1.6TDi (118) is 10.5 seconds btw. Most smaller cars (non sportcars) are faster 0-30 but slower 0-60 (than 11.0 seconds).

Well mine is 114. I don't find any problem keeping up with 'normal' traffic even on the continent, four up and full boot. The only drawback is when you come to a hill that is a 'proper' hill. That is the only place that I think it would make a difference to me. Always cruise around 70/90 when abroad and still get 52 mpg or more.

Many thanks.

Will any switch do, where could I get one from.

My ZTT has the remap and the extra power is noticeable.

It pulls like a train going up hills and on the flat if you press hard.

90% of the time I cruise around at 40mph and only occasionally get to do 60mph depending on speed limits.

As for the automatic gearbox they have been developed to handle more power/torque because they have to.
You can't have a gearbox that can only handle up to 160hp that just doesn't make sense as it would break in an instant.

Plus these automatic gearboxes are used by VW and Ford plus I expect a couple of other manufacturers.

Can the the 2.0TD be upgraded?
Of course it can it just depends on 'how much money you have'.

The engines will take more, it's our turbo is the big issue.

The same unit is used on the clio 1.5 dci

That should tell you everything.

Im selling a car to begin a full "big turbo" diesel car with the plan to see just how much the engines can take, and then if it blows replace it with the spare and dial it back a bit lol

I know you can fit a larger turbo but without making other changes it's useless on it's own.

What I would do is contact Turbo Technics for example and ask them what can be done.

Also look at improving the airflow that all engines require if you are after more performance.

I'm think I'm correct about this that the diesel engines put out 300Nm of torque, so increasing torque is the most important thing as BHP on it's own isn't enough.

116 PS = 270Nm
131 PS = 300Nm
160 BHP (162 PS) = 359Nm

The biggest killer is airflow, you can inject more fuel, but it simply leads to black smoke

Also the clamping load of the clutch can be overcome with excessive torque

Finally the M47R has a cast crankshaft, not the forged item in the M47 variant, and you don't want to snap it in the centre main bearing journal, this I have come across on more than one occasion with cars in standard tune

What's the difference between the M47 and the R Brian? Is it the M47 was fitted to BMW and the R to the 75/zt?

Yes that's right Richard, and the M47 has a forged crankshaft not a cast one.

Externally they look very similar, but you can't exchange one for another without a lot of work
