Do you mean the EVO SEVEN (VII) or is there an EVO TWELVE (XII) planned?

If you mean the EVO 7, then no, totally different than the 90-99 GSX 4g63.

Google evo 7 engine and then Google gsx engine and look at em.

sorry i ment the new evo 8, at least i think thats it, the one that just came out, they said they brought back the old 4g63, if it is any better... would that be an alright i dea to drop it in a gsx?

you might be able to drop it in, but there will be distinct differences that you will have to deal with. most involve motor mounts, perhaps driveline issues. the evo 4g63 is reversed from the dsm 4g63, tranny on the drivers rather than the passenger side.

The EVO 8 (VIII) Is not new they came out in 2003, the newest that is out is the EVO IX or 9. None of the the EVO engines after the EVO III are the same kind of 4g63 as in a 90-99 Eclipse. So no none of the new EVO engines will fit. The EVO X will not have a 4g63 either.

Go find yourself a 6-bolt longblock and save yourself a lot of money and a big headache.

The only real advantage (excluding the bolt ons) that EVO 4g's have over the GSX 4g's is Mivec. Like he said above me. A swap wouldn't be worth it.

no i dont think id ever do it lol, i just wanted to see if it was possible... Thanks for the update... and wat you mean 6 bolt long block? thanks!!!

6 bolt is the 90 to early 92 dsm 4g63. Late 92 to 99 is the 7 bolt. 7 bolts are known to crankwalk. Read more at www.vfaq.com

It's always POSSIBLE to do swaps. The question is how mnuch expertise, time, and money will it take.

Agreed. I mean they even have Mirage's with 4G63 motors in them running around, although I've head that's a b*tch to put in. Now for a different swap. 3000GT VR-4 motor into a Eclipse LOL. Now that would be hella different, but I don't think you could do it, but it's always nice to dream haha
:D

Crankwalk on the 7 bolt motors is not something that happens to everyone. My cousin had a low 10 sec 98 GSX that was a built 7 bolt, owned it for 4 years, never had a problem with crank walk. There's plenty of guys out there running 7 bolts without a problem too. But, I'd say it's cheap insurance to just find and use a 6 bolt.

First, 4g63's drop right into '89 turbo Mirage's (with the 1.6l). All that is really needed is the motor, ECU, intercooler, fuel, and a new exhaust. Even the tranny is about the same as a 1g turbo tranny and can hold the abuse. The 4g63 also drops into Mirages with the 1.5l N/A (4G15) relatively easy. The mounts are needed but it will still bolt right in. Just some wiring work to do. Anyways, point is, all three of those engines are relatively similar (the 1.6 and 2.0 are practically identical). Now, putting a considerably heavier 6 cylinder into a T/E/L would be foolish imo. It is a 3.0 block, so while you are gaining 2 more cylinders (I would rather have less...cheaper, better on gas, etc) you are only gaining a liter of displacement. Now, there are tons of strokers out there (2.3) as well as 2.4l that work very very well in a T/E/L. I see no reason why anyone would ever want to go through the trouble of trying to bolt in a 6g72 (which like I said is considerable heavier and doesn't even take to mods as well as the 4g63 does), but that's just me. Does a turbo 6 cylinder sound appealing...of course! (Think Skyline, Supra, etc) but I just don't think it would be worth it even if it could be done. Just as almost everyone feels about swapping in a 4g into a 2gnt...just not worth it.
