Default Swap ER27 for EZ30?

I don't think anyone has tried this before. They always seem to go for the EG33 or some turbo from an sti.
Anyway, I bought an XT6 that has the stock ER27 engine it came with. There are several areas of concerns as it seems to have been tinkered with by a hillbilly's son.

Before I go through the expedition of taking apart the engine to replace a blown head gasket alone, without knowledge, and armed with a Chilton repair manual, I'd like to know if anyone thinks a swap with an EZ30 is possible without major modifications (such as sawing out the engine bay, mounting the engine in the back seat, that kind of major).

I like the reviews of the EZ30. It's newer, more fuel efficient, has more readily available parts, could take it to a real mechanic, oh yeah, and it's more powerful!

I also want to know if it's too much trouble with the drivetrains. My XT6 is a FWD 4-speed AT, and the donor car would probably be an AWD 4-speed AT. It seems ok, except for the difference between FWD and AWD.

Please bestow me with your experience and thoughts!

I suspect the EG33 is going to be a much more common swap than the EZ30. The engines are cheaper to source and there is much more known about the tuning of these engines. On the other hand, the EG33 is longer than the EZ30, further complicating the spatial conflicts at the front of the engine bay.

On my car, the radiator just barely fits in the stock location. What sort of chassis modifications are required to fit the EG33 in a GM/GC/GF chassis? Given the extra length of the EG33 (vs. the EZ30), did you have to relocate the radiator farther forward? Anyone?

for reference, the EZ30 is .7 inches longer than an EJ 25.

Why would he need to tune it? I'm pretty sure he just wants it to be stock.

OP, not many people do these swaps so you are not likely to get any advice from somebody who has done it. I think you will need a transmission adapter to fit that motor to your existing tranny. Not to mention a ton of custom wiring and fab work.

Of course they have. The EZ30s have been around for a dozen years now, someone was bound to have put one in an XT6 at some point.

Search youtube for XT6 EZ30 for videos of that car on the dyno and being driven. Looks like the owner doesn't post much but is still active on the forum (as of a couple weeks ago) so you can hit him up for advice.

Thanks guys! I don't have a donor yet, but when I do, this'll be very useful!
