Can anyone give me a price range for a version 7 (02-03) JDM STI transmission?

Depends on what it comes with, but anywhere from $2500 to $4000 for just the tranny.

I bought a complete tranny swap, with hubs for about 3500USD shipped.

Check out JDMSpecC4U on here.

thanks, I'm asking because I'm considering buying a front clip that comes with everything, and the only thing I need is the engine, ecu, turbo, IC,.. etc.. and I don't want to do it if I won't be able to sell the tranny, it also has brembo brakes

you should be able to sell pretty easily. i am going to do the same thing myself to put into my GC. i already have a USDM STI tranny and hubs/brembos and everything that goes with that, just need the go fast parts. :) too bad you arent the other way around and just needed the drivetrain as i still need to find someone to go in on this with me. i will be selling everything for 3500+ shipping (will be v8)
