3kgtvr4 getrag in a 2g gsx

[my4ATEurV8]

i got the wild idea of swapping a 3000gt vr4 getrag manual tranny in my 2g awd. im aware that its not a direct swap kind of job but, im going to try and get it done. has anyone ever done this before? i already know how to get ahold of custome cv's and drive shaft if necesary. can anyone give some insight on the challanges with this?

 

[my4ATEurV8]

i know i can use a supra tranny if i want to go rwd, but i just cant let go pf the awd launch. if im able to complete this swap then i will have a very strong trans. im able to pick up the 5 speed if i tell the guy i want it. are there any major differences in the 5 vs the 6 speed?

besides the extra gear........hardy harr harrr

Beside the trans I assume you'd also need to fit the transfer case and rear end. I've never looked at one of those transmission so I don't know if it would even be close to fitting dimensionally. ...And then you'd have to match up so many other things, possibly a custom bell housing, different clutch fork, get the pilot bearing working, etc, etc, etc.

 

[housegsx]

The 6 speed is a Getrag I believe. A much beefier unit. If you don't go 6 speed, I don't even see a benefit.

You will need a 94-96 vr4 trans, transfer case and rearend. 25spline..wrong as nails. Also will need custom axles... IMO its not worth it, but i say do it up

 

[my4ATEurV8]

spoke to team rip today about this. he said that the getrag was a 5 and 6 speed that only came in the twin turbo models. im going to do a ton of research on this.

 

[my4ATEurV8]

im thinking the getrag should be around the same strength as a dogbox. ive read about vr4 getrags holding 1000+hp bone stock. if i am able to figure out how to make it work, then ill have tre do some gear detail work, shot peening and modifi the sincros. i think it will totally be worth it. im only going to be doing around 650 awhp and i intentionaly slip the shit out of my clutch, so this trans theareticaly could be my last.

 

[hubz91talontsi]

The 5 speed is only a 18 spline and notorious for breaking trust me.. Get the 6 speed.

thats good info. thanks
never even thought of that
but i did find out that they are netoriouse for bad sincros, further reading indecated that mitsu recomended the wrong oil. several sources, including pro trany builders(not just tre) said that if i use redline products, the sincros will stay happy

Auto's don't break, I think I am going to line up an auto swap. I'm entirely sick of thinking my trans is going to pop(oh.. I've been through a few).
As for a 6 speed swap, that is a good idea, I've been thinking you might be able to get away with a mockup and a spare 1g trans. IE NA fwd bellhousing hacked up to mate to the vr4 trans and welded/reinforced to get it workin' proper.
I've got a junk 1g trans to play with, want the bellhousing off it? haha

the 5speeds can be either a 18 or 25 spline depending on the year. the gears are much taller than ours. I am working on a friends 1992 3000gtvr4 now. there are upgrades for these too. you can get an aftermarket stainless steel tcase housing! oneof the only things that breaks on these trannys.

I also noticed that the slave is on the firewall side of the trans and I thinks is on the front (not sure tho its late and im tired)

i was thinking of this the other day if anyone made like a kit for it to work. Hondas have kits like an H2B kit. Where they use H-series engines and B-series trannies. I just don't see how it would work for a Mitsu application. For all the work and it just might be better to invest in a real Dogbox tranny. Although it would be cool if you get it done.

Yeah that's the issue, honda's are far more 'bolt together' friendly than the dsm family. Fairly obvious if you see a 3si vs dsm trans.

Wtf are we supposed to call a 3kgt/stealth anyway? aren't those considered dsm's too?

 

[my4ATEurV8]

no i dont believe they are considered dsm's.

 

[my4ATEurV8]

hell ya ill take that bell housing off your hands. save me from hacking an awd unit. let me know, ill pay shipping.

 

[steve]

They are called 3S cars, they are not DSM's. The NA 3S share more with the DSM than the TT cars do.

 

[Rob10_99]

Oh yeah that's right, their forum is 3si, duh...

But the dogbox needs to be rebuilt very often. also they are not street friendly at all. Then you have the taller gears and the possibility of an extra overdrive. these are great trannies just would be pain to make them fit.

then lets all pitch in and make it happen! im trying to get vendors interested! if im succesfull in making the getrag working corectly, i want to design a kit.

This makes no sense. Only the TT cars used the getrag transmissions and finding parts to keep those going is hard enough. Parts for the DSM W5M3 transmissions are still being made and it's not the transmissions breaking on high HP DSM's.

Knock yourself out but I think this is a windmill.

 

[my4ATEurV8]

im well aware that the getrag only came in the turbo 3S cars. im trying to make a viable option for a much stronger trans then the weak crap that came out of the factory for our precious dsm's without going to a not very street friendly dogbox or losing our ace in the hole=awd system.
somebodies got to do it. i dont think it will be ready anytime soon, but i want to have it ready for next summer. i decided to make it my winter project. so steve if its a windmill, do you know of any other awd transmissions that could be fabbed to work on a dsm that is a lot stronger than our oem units?

+1 They are not as strong as you think either. The housings are also known to break when you run power through them too. Not a good trans, definitely not worth the trouble of getting it to work which would require a lot more to do than you think. Trust me, I put a 3S engine and trans in a GVR4 and it was stupid.

[my4ATEurV8]

so then Mr. jack, do you know of an awd trans that would be a better option.

 

[my4ATEurV8]

its not like i have anything better to do

 

[GsXtacY325]

so then Mr. jack, do you know of an awd trans that would be a better option.

Yea, send your dsm trans to Jack, or shep, or TRE, or dogbox racing
