Get yourself a good AR35 gearbox (the existing AR25 box will very soon die once you increase the torque), whack it on...and chip the engine...

I have 3 or 4 good AR35 boxes here if you want one for a decent price (£100)...job done!

Most of the chips, inc the one I have in mine, improve drivability and economy, and give a noticible boost in power.

If its an auto, it will shred the gearbox though - there is a reason Vx detuned it to 250Nm or torque...

As stated above, chipping the 2.5 diesel does shorten the life of the standard auto box, but if yours is a manual or you dont mind replacing the box with a 3.0 one when the existing one lets go, you will enjoy better performance and MPG  :y

True you could continue to use your existing box until it dies which will apparently be pretty quickly once its chipped...but I would have the 3.0 box bought and ready...as it wont be long before you need it :) lol

And the chip provider I use is based in North Oxfordshire, and has maps for all the different TD ECU types.

Be aware, some of the later ones (late 427 and 428) may need sockets soldering in.

Failing all other suggestions, you could always get yourself a 3.2 MV6.....power by the bucket load! ::) ;)

Couple on ebay from Germany...says the chip gives an increase of power from 130 to 160 bhp and 250 to 320 nm torque which if correct is not bad at all...

Most definitely an AR35 box needed at 320Nm as AR25 box is 250 max...I have 4 of them (soon to be 5) by the way if you need one too lol :)

I get mine from a guy in Oxfordshire, iirc £70 delivered.

If you want to contact him, rather than me post his contact details, PM me your mobile, and I'll get him to call you direct.
