If I win the lotto

725 to 765 lbs of weight, that's quite a bit though.

That is one fat 4 banger!  I'd still do it, with the NV4500

good idea, that's another 250lbs

Does this beefy drivetrain make my Jeep look fat?
It would prolly be a good idea to add a D60 or 2 to make up for the TQ. and added weight.

Well, unless he's going to keep the 2.5L and the AX-5 he's be shedding 400lbs at least.  Then if he didn't get in it, it wouldn't be so bad.

I'd like to call them and get a few quotes and a few more facts. I'm still leaning towards the 1.9l swap for this summer.

[sharpxmen]

the TDI is probably 1/2 the weight, you can always flash the ecu for more torque - in your case with the 4BT you'd definitely have to regear (won't rev nearly as much as the tdi)

Yup, the 1.9 just seems like a better swap
