STi 1's and 2's are very hard to find, and not all that great either. V3's-V4 are much more common, and better boxes than the predecesors. Thing is, there are varying manufacturing dates and models they came in. To av it work with the rest of your drivetrain (i.e. rear), you need one with a 4.11 internal ratio...this will match your RS' existing rear ratio. V5's and V6's are still both speeds, and get very pricey. Plus, they only have 4.44's rear in the STi versions, so you will need a new rear, and possbly axles too (not sure about this, but I think so). I imagine the 6 speed would bolt up to the RS motor....after all, the WRX is still using the EJ20. But the extra gear may mean the tranny doesn't fit into the tunnel of the "old" RS bodyshell...only time will tell (Someone is bound to try it). Anyway, prices are (roughly) as follows:
Again, all these are for used STi tranny's, not for WRX units. WRX ones are more common, and generally cheaper but not necessarily as strong (though even the STi units are not bulletproof)
V1, V2 - $900
V3, V4 - $2,000 - $4,000
V5 - $4,000 - $5,000
V6 (have yet to see a used one - I think they are around $6500 crated from Subaru, but agan, not sure. Make sure you ge tthe clutch and flywhee too..your existing one won't work (won't even fit!). If you go with certain V4's (non-RA's), V5, o V6, you will need the rear and axles too.

I have been down this path when sourcing the tranny I run in my car...best thing, save your money, and get in touch with Rallispec..have them source you one of Brett's boxes from MRT...a much better, long term option IMHO.

Post Used sti transmission?

How much would a used sti/ver.3,4,5,6 transmission cost 5spd and will it synch up to the rs with out modifications. yes i know it depends on mileage but how about a rough figure so i could start saving. Thanks

PS Would a new6spd be priced competively against a used one.

I think used STi parts are generally hard to find, but I recall that the SPD website lists new STi tranys for sale. Try there.

Adam99rs,

What tranny are you running in your car?

I'm still wondering when my clutch is going to completly die out (been slipping for 2.5 months). Wondering if I should plunk down around 1k for a light flywheel and clutch or.. maybe just replace the whole thing.. ala Rallispec.

I am using a 1996 STi Type RA tranny in my car, withthe original non-LSD rear, and stock axles all around. I mated this with a 14 lb STi flywheel, and the clutch from an STi V5.

In terms of what you should do, it all depends o how you use the car, and what your budget is. If you can deal without monter launches (whici is what kills the clutch/tranny on any car), then just go clutch (ACT, etc.). That is also a good option if you are done with your ods, and don't plan for big power (say, over 275-280). If you want more than that, and longevity, the ACT will ultimatly fail too (I went through mine once the car hit 12's). From there, your options are either a WRX unit, or the BPM or MRT ones. The ice thing about using these is that you have endess clutch options, and both are much stronger than the RS unit. But, they are pricey, and there is a wait time involved.
