BMW 330D VNT turbo with an aftermarket VNT controller. You'll be able to max the fuel system out at 180bhp. And you'll be acheiving 180bhp from around 2500rpm all the way to the red line! If fitting a larger turbo you need VNT or you'll have no boost low down and you'll put a massive shock through the entire drivetrain when you get boost.

It's not too hard to achieve

I'm sure I've seen a company somewhere up north that will fit a bigger turbo and remap it accordingly, but I can't remember the name. They're on one/some of the facebook groups.

No fun I agree

But modifying cars these days will make it un-insurable.

That's a lot of messing around for only 180 bhp. Think I'd just go the 160 (ish) remap route and save my cash.

I agree, if you really want MG/Rover buy a MG ZT190 to start with.

It's not just the peak power, I've attached 2 images, one is the dyno run of my old ZT with a VNT turbo, and one is of a car that has been mapped with the T4 Operators 160 map. Torque is what you really want. Both cars were run on the same dyno which is properly calibrated.

Does anyone know which 330D VNT turbo to use? I had a quick look at 330D options and there appear to be 3 or 4 different turbos for the 330D.
The option of more/earlier low down torque and then more mid range torque across the range, with a little bit more around the top end, is attractive to me as I often travel loaded or towing and that would help nicely on my manual 135 tourer.
As mentioned elsewhere, the low and mid torque is what would be nice for me, but big top end horsepower numbers would not be the aim for me.
Does anyone know what the torque limits are for the clutch and the gearbox? I do not want to push the gearbox too gar whjilst towing either.
