I thought I would post this stuff on here before I offered it up to the kiddies on Facebook and dropkicks on Gumtree!
After careful consideration I have decided to go Auto in my Mirage Cyborg build. I spent tons of time and money on this setup and even went as far as travelling all the way to Adelaide from Melbourne (twice) to get this gearbox and transfer case built by one of, if not the most experienced and passionate Mitsubishi 4WD transmission builders in Australia, Mike Dale (blackvr). I still have receipts for all work carried out.
Please read these specs carefulyl so that this box/ratio etc suits your application!

I also have a 2.848 rear diff centre from a manual C73A if anyone is interested. I have a 2.848 front diff to match it too.
I also have a brand new Fidanza flywheel to suit a 4G64 FWD

Please, serious enquiries only. Prices are firm and sorry i'm not open to swaps for WHY. Pics available on request
If you haven't assembled your gearbox yet then definitely swap them over internally. I got my gearbox built by blackvr (Mike Dale) over in South Australia. Unfortunately it wasn't until it was already assembled that I found out they were different. On 4g61t.org I read that you can cut and weld. For me, this isn't really ideal but is going to have to do for now.
FYI, I had the VCU in my '88 GSR's KM221 fuck out on me which gave me symptoms of clutch slipping. 2 clutches later, I realised what was going on and decided that unless I went Auto (where's the fun in that??) that I needed a W5M33 instead.
Eproms are pretty old school aye. Unless you know someone burning them or are doing it yourself, I would look at using an EVO 7+ ECU instead. So many more features, functions and tuning capability. Not to mention every Tom, Dick and Harry tunes them these days
Your setup sounds similar to mine- which made 221kw on 21psi. I wanted to run a few extra PSI but had boost control issues. I would look at upgrading your clutch (if you have one) suspension and tyres for anything over 200kw rather than trying to make it go faster. TD05's come alive over 20psi. IMO they are one of the best turbos you can have for a street car.
