Yep that's the bit I want to rebuild the GTi box. I'll pm you.
Anyway, have taken some pictures, linked as URL's because the pictures are huge and I cbf cropping them, also you can see the detail better.
This is the culprit.

It must have been ,driving on the teeth on the end for a while which is why they look like they do I suspect. Some idiots taken a cino hatch short shaft and stuck a GTi CV on the end.
https://i.imgur.com/2WlgfaR.jpgHave got it back together with a Cino box in, replaced the missing gearbox bolts and flywheel cover while I was at it. It lives and seems to run fine although with the 16s on it the cino box feels bloody slow compared to what the GTi box did, fuel economy in fifth though will be better, looks to be nearly 900 rpm difference at 100 which should be good on the way to work. Am thinking that I might use the rubber up on the 16s then just buy some nice looking 14s anyway. That way I can replace the inner guards that someone took off.
Calibrated the TPS while I was at it. Followed the instructions in the tech section and while it made my run on throttle better it's still pretty bad, up to a full second of lag after taking the foot off although it seems worse at low revs which is weird. It's slightly ruining my enjoyment so I do want to work out what the hell the problem is and fix it. TPS could even be stuffed for all I know.
Tidied up some very dodgy wiring and put a genuine thermo fan in where it had been replaced with an aftermarket one wired in to accessories. Need to get the right size switch for it though as there's not one on the thermostat and for some reason the AC switch is in the thermo switch port and the AC switch port has a brass bung in it. It's making life hard as they appear to be different sizes, the switch out of my cino appears to be an m18 and the port on the GTi looks to be an m16, but the AC switch port looks smaller again m12? maybe? So I need to get a smaller AC switch and thermo switch.
There's a g16 sedan at the wreckers down the road that's supposed to have the right thermo switch in it but I doubt anyone locally will have the AC switch I need, may have to see if I have the right thermostat housing or maybe get an m12? -> m16 bush.
Going to try and get the thermo switch sorted out tomorrow, put some actual coolant in it (people that use water instead of coolant should be violently murdered) maybe put the AC compressor back on, pull the dash out of the cino (350000kms on it but the dash is immaculate, which is more than can be said for the GTi's dash) and then spend some time trying to sort out my throttle issues as well as sorting out central locking some better speakers and the passenger side window not working at all, and the drivers reg being lazy....
Sigh... this was supposed to be a car I could just drive to work in and have fun, one day I'll buy a car and not spend time on it. (No I won't)
