A 1.9 non turbo in a transit?
Even the 75ps was a 2.0 tddi.
Go to the transit forum, there is some pretty good ones over there. If yours is a 75ps, de cat it, blank the egr, fit a intercooler off a 85/100ps transit (make sure you clean it out first) stick a load of diesel cleaner through it and take it to van tuner off the transit forum. It will seem like a new van then!
As for looks, I fitted mk7 wheel trims and kept mine clean! Mk7 rear lights also fit and good sign writing helps loads too.
