I know at least one guy in the US is using a 2.79 with his 1.8 liter M42 16 valve and getting some pretty phenomenal FE in the process. Its just a matter of how much acceleration you're willing to sacrifice.

To reduce parasitic drag you can ditch the PS pump and clutch fan. It was a nice improvement on my M42, swap in Bosch Design 3 injectors (EV6) for better fuel atomization. Right now you have the injector on the left, EV6 on the right. EV6 produces a much finer mist without increasing the total flow.

These injectors can be found all over the junkyards for dirt cheap.
I wish they sold the wagon in the US. I had to settle for a 4 door 16 valve.
good luck

Justin, thanks for the suggestion. I'm thinking of a 3.64 diff for the rear end.

As for injectors-I was mpanning to swap in a set of 4 jet injectors from an m50 or m44 lump.

I'm contemlpating an electric fan conversion, but wondering how if its worth it as the fan is driven off the waterpump. Waterpump and Alternator are on the same belt too..

Euromodder,

No mudflaps, although i'd be tempted to use some as tyre air deflectors

A grill block is definately up there!

Anyone got any ideas regarding sheel covers/moon discs etc?

I'm assuming a full length belly pan would be advantagous too?
