dosquattro Posted May 18, 2007 Share Posted May 18, 2007 Maybe find someone to make an adapter plate or custom bellhousing to use the RB26DETT tranny. Then you'd have to do some modifying to your oilpan as the front driveline goes right through it. Not to mention I think it's gonna make your engine sit further ahead. I just think it's a waste of time. Stick with what works. Quote Link to comment Share on other sites More sharing options...
Gareth Posted May 24, 2007 Share Posted May 24, 2007 Before you start the swap, remember one thing - Eclipse and Evo engines are mounted differently in the engine bay. What I mean by this is that while the Eclipse GST and GSX have the flywheel and gearbox on the left side of the car, Evos from IV on had gearboxes mounted on the right, or it may be the other way around. Anyway, this is why DSM guys can't just swap the 6-bolts or 7-bolts for much better Evo engines. As far as I know, original Mitsubishi gearboxes are not up to the task when paired with a DSM or Evo motor. I don't know about the details, but I read somewhere that they're just weak, that's all. There are adapters for Toyota W58 and R154 gearboxes, and they both easily handle that kind of power. Also, Mazda RX-7 Turbo II gearboxes bolt right up, as long as you use the right bellhousing from a Mazda pickup that had a Mitsubishi engine. Dunno if an FD3S gearbox will fit - there are 600HP FD's that run on daily basis, so they should be a good replacement for the TII ones. A 4G63 swap would surely be original, and with the motor's aftermarket support, stout cast iron block and tons of DSM experience it should not be that difficult to make a Z a really fast car. Reliability is another issue - I'm pretty sure that you'd have to spend quite a lot of money to get this going. Good luck! Quote Link to comment Share on other sites More sharing options...
Pete84 Posted May 24, 2007 Share Posted May 24, 2007 How tuneable is the 4G63 turbo's ECU? To do this swap in CA the ECU had better be fairly friendly to work with. Tons of blocks + options for a transmission = possability. Quote Link to comment Share on other sites More sharing options...

Tons of blocks + options for a transmission = possability. probably second only to the ls1.. http://dsmchips.com/ this guy can do anything you want... 1000cc injectors? no prob. and anything inbetween running race gas? he can give leaner mixtures and agressive timing maps for anything you want. i've seen a talon in the 9's with one of these chips and a SAFC with 1000cc injectors of coarse you could do what most fast dsm guys do and run the dsmlink and make your own changes http://www.dsmlink.com/ i currently have a hybridized 4g63 swapped car but mine is FWD. and let me tell you what, this little motor rocks.. 20psi daily on pumpgas and all kinds of traction problems... http://i74.photobucket.com/albums/i277/turbokid1/DSCF0203-2.jpg http://i74.photobucket.com/albums/i277/turbokid1/DSCF0208-1.jpg Quote Link to comment Share on other sites More sharing options...

Reliability is another issue - I'm pretty sure that you'd have to spend quite a lot of money to get this going. Good luck! FYI - this stuff has already been documented in this thread and another thread very recently (within a week or two) (http://forums.hybridz.org/showthread.php?t=121875) along with a couple other threads in the past 5 or 6 years. If you're interested in this swap, just go to http://www.projectzerog.com That's where it's all happening. Also, the W series motors are NOT as strong as the R154. The kind of power the 4G makes stock would be fine for the W series but if you start putting close to 350HP or 400HP it's time for the R154. Bill Hincher (Japanese Auto dude on Project Zero G's forums) is the designer of the custom bellhousings. He originally made them for the W55/58 transmissions and had adaptors for using the R154. He didn't like the freaky adaptor for the R154 so he decided to design an entirely new bellhousing specifically for the R154. He has NOW just started revising the original bellhousing design (W55/58) using things he has learned through his process - basically, these revisions make them stronger, simpler, and cleaner. Check it out: http://www.projectzerog.com and go to the forums. How tuneable is the 4G63 turbo's ECU? To do this swap in CA the ECU had better be fairly friendly to work with. Tons of blocks + options for a transmission = possability. Very tunable(sp?). But, in my opinion, one is better off with a standalone unit in this case. It wouldn't be much more expensive and you wouldn't have to worry about exploding capacitors in the factory computers. If we were talking about an LS1 or another engine with freaky sensors (late model EVO engines already making ~300HP with the factory tune), I would say try to stick with the stock ECU and use tuners. But then, would this just be another standalone engine management argument? Quote Link to comment Share on other sites More sharing options...
Pete84 Posted May 28, 2007 Share Posted May 28, 2007 Pretty much a shot in the dark, but would a 6G72 bolt up to a 4G63 transmission / adapter plate? Quote Link to comment Share on other sites More sharing options...
ShaggyZ Posted May 29, 2007 Share Posted May 29, 2007 Pretty much a shot in the dark, but would a 6G72 bolt up to a 4G63 transmission / adapter plate? Honestly, I have no idea. However, you can be pretty sure it will not. Seeing as there are plenty of RWD applications out there with the 6G72, I don't know why you would care.
