All back together smaller 1100 clutch and flywheel fitted to 1400 Mpi no problem works fine, only still has crap feel clutch low on the pedal so assume cable length or pedal ratio is wrong?
Now have new fault, drove to town to test everything out and drove it hard in 1st and 2nd to see how gearbox is and how acceleration is with these ratio's short lived experience as by the time I changed up to third throttle had stuck and I got in to third with engine doing 6500rpm! panic set in and by the time I'd thought to key the engine off and stopped, the car was full of clutch smoke! for a while I thought we'd caught fire! lol clutch survived and I found the nipple on the throttle body segment moves and jams the throttle open! weird it never did this before? still it happened again on my 6 mile round trip so clearly somethings not right with it!
Working on the car is not as easy as you may think! being mid-engined its easy to look at it and think simple remove rear body work (this is almost a 2 minute job, only hampered by having to disconnect ALL rear lights) then you can walk around the engine, well this is sort of true.
Problem with gearbox out is in this car the bulkhead is in front of the engine and to achieve a good compact design it is tight to the bulkhead so on the Metro/100 you can remove the member from the subframe to the right of the gearbox and move box in to that space before lifting out, on the GTM you find that the gap between bulkhead and rear of subframe isn't as big as the bell housing! in the end I had to remove clutch and flywheel which only just makes enough space with the engine at exactly the right height to get box down through! If I didn't have my Dads pit to work in I'd have been buggered! Engine and box out may have been easier as that may be achievable up through? but not entirely convinced.
Separating subframe from car may have been easier but I'm not sure, to separate you need to disconnect all wiring from ECU and earth's ect from Subframe, and drain / separate cooling! once the cooling circuit is opened on a mid engined car there will be air locks so its all more work than you'd expect from a Metro/100 once separated you still got to take apart suspension ect to get box out! my suspension is still linked so something else to separate at the mo!
Definitely want to individualise sus now! The link pipes in the engine bay of a GTM are a real pain in the arse when you want to do something! Current thinking is to get two more rear units from a scrap Tro with their valves and tee piece and cut and weld the tee. Once this done I can remove my entire Hydro system and replace with these and two individual Mini units I have. Always planing these tasks so the cars off the road as little as possible, if anyone reading this is building or renovating a GTM individualise the sus from day one, its got to be simpler and better all round.
