seeing as excel boxes have been mated to gti engines i would have thought it wouldnt be much more difficult to do the reverse. or am i way off?

maybe but a GTI box is still transverse and flywheel/clutch etc is all unknown.

But there's other issues here - engine mounts, accessory mounts, sump, manifold and coolant hose position all may or may not be issues.

There's generally little point in using a FWD motor (of only moderate output) just because it's cheap. Much better to use an engine that was/is available in a RWD format so you know there's at least some chance it's going to work. There is some case to go through the pain if it's an exceptional FWD motor ( Mivec mitsubishi, 4AGE20V/4AGZE etc) but then gearbox choice becomes even more critical.

I also see no point in attaching a more powerful motor to a sierra gearbox. Vitara is much better option (even a manual vitara box if you are bit queer) because they are newer, stronger (particularly clutch and flywheel the manual), and easier to get hold of.

Adapting a cheap motor to a sierra gearbox is putting good money after bad in my book.

The clutch and flywheel on a vitara box is way superior, and an adapter is eliminated. Granted the gearbox mount and jackshaft need work, but that's no more money than an adapter.

There's nothing inherently wrong with a sierra box, but considering the G16 is probably being split from a vitara manual in order to be bolted to a smaller flywheel, clutch and manual and it doesn't seem to make sense to me.

spin's up quicker, & a clutch will last long time if geared & treated right...

True, but a heavier flywheel is an advantage offroad.

Being different is all well and good and I'm the first to say go for it. However the expenses with being different skyrocket. Its alot easier and cheaper to go with the trialled and tested. Like many ppl have said how much power do u really need in a 4wd. When ur putting crawler gears to go slow u don't need a huge engine. If u want power build a race car

Yeah but it's nice to actually be able overtake a slow car occasionally or not have to work the car just to keep up with traffic on hills, or have to drop back gears everytime you come up to a hill.

If I ever do an engine conversion, I'm not aiming for traction breaking power, but enough so I can do all of the things mentioned above easily.

All our cars are very underpowered.

I like the quick spin, can't see the gain of a slower rev.... for what I drive....
