Expert Posts: 2230 Location: Ripon, North Yorkshire | Swapped with gearbox with the old one today, difference is 5th gear taller and 3.9fd instead of 4.2. Will pull the new gearbox apart when I have more time. It seems more than likely having done some research to be a problem with getting the 5th syncro misaligned. It fell off when I went to put the gearbox back together  Edited by jasonr 29/4/2010 12:57 PM | ||

Expert Posts: 2230 Location: Ripon, North Yorkshire | f**king car, got everything connected back up, made up the brake lines front and back, got the throttle cable connected up at both ends. Went to fill the coolant system up with water and it started pissing out the front of the radiator - I've managed to put a hole in it > . Now luckily I have a new radiator that was going into the MGF, but I will now have to get that fitted to the race car. I also need to find out what size the union is on the clutch slave cylinder as it's bigger that 7/16ths | ||

Will pull the new gearbox apart when I have more time. It seems more than likely having done some research to be a problem with getting the 5th syncro misaligned. It fell off when I went to put the gearbox back together If you have the 5th syncro assembly misalligned the top case of the gearbox would not physically go back on, as the syncro hub/sleeve would be sitting proud - approx. 15-25mm. When you put the gearbox into the car was the gearbox always in neutral even though the gear stick would feel like it was engaging gears? Or was it always in gear and you couldn't disengage? If it was always in neutral and it felt like it was engaging when moving the gear stick, then the interlock arm will be incorrectly located onto the selector fork pegs. Have you refitted the gearbox that I built for you about 2 years ago? Still going strong? Regards Lee | ||

Expert Posts: 2230 Location: Ripon, North Yorkshire | Well, I've fixed the radiator with chemical metal, but for good measure I will put some rad weld in the coolant system as well. I've got the car sat on it's wheels now, so I can finish off the interior more easily. I've fitted 4 spot light steady brackets between the splitter and the bumper to stop the splitter deflecting and to allow adjustment of the angle of the splitter. The unions on the sandwich plate are leaking oil, so I've got some dowty seals coming in the post. I'm stuggling to find out what size the union is on the slave cylinder, it's not 7/16ths it's about 11 or 12mm in diameter.  | ||

Expert Posts: 2230 Location: Ripon, North Yorkshire | Not been making much headway with the car this last week. After a failed attempt to bleed the brake last week. Broke the inline bias valve, so ordered a line lock and some new unions for it. I have now ditched the hydraulic handbrake. Having fitted some pro-tech coilovers on the front so I can fit 2.25" springs. I have had to remove the bracket that the brake lines fit to and repositioned it, in a better location. I will have to redo the copper lines at the front though. I also noticed I had fitted the front calipers on the wrong sides. This meant the bleed valve was at he bottom of the piston not the top :  , swapped them over today.  Uploaded with ImageShack.us Edited by jasonr 16/5/2010 12:32 PM | ||

Expert Posts: 2230 Location: Ripon, North Yorkshire | Well, the car had it's first outing this weekend - in France. The St.Goueno-Masters hill climb http://www.st-goueno-masters.com/. This event has been planned since the end of last year. 2 mile hill climb and it was awesome, unbelievably fast and with only 6 runs over two days there was no way I was going to master it, but I put in a 2 minute run as my fastest time. Happy with it as i've still got to learn the cars limits and on that hill climb you can't afford to get it wrong. The weather was ridiculously hot as well 8-)     | ||

Expert Posts: 2230 Location: Ripon, North Yorkshire | Well got the rear subframe swapped today (the old one was flexing) and the rear setup with 1 deg neg camber. Need to get it on the ground to get the toe set to 0. Also fitted the new protech coilovers to the rear as well. After bending the front bolts that hold the front coilover units in france, as they are in single shear, I made some brackets up to but them into double shear and am now using 12.9 bolts as well.    The new rear beam has mini rear adjustable camber/toe brackets on it now.   Edited by jasonr 28/6/2010 1:13 PM | ||

Expert Posts: 2230 Location: Ripon, North Yorkshire | Once again Lydden became the first place I raced the 'new' car as I did in 2008. It's a good place to do it, as you and the car get no let up with such a short track. I had addressed the problems that presented themselves in France so now would be the time to see if I had really sorted them out. Well not entirely as both the poly bushes that support the centre section of the exhaust melted and came off : >, one trying to take one of the other drivers out. So I will be getting some small link chain to use as exhaust supports. The car behaved well in practice and I steadily increased my pace. It is now more stable and has more grip, all I have to do is teach my self to exploit it. I think I can start to brake later than I used to as a) the brakes are now better and b) the car is more stable. Unfortunately all did not go as planned, I had a poor start to the race but soon made the ground back up, but after about 5 - 7 minutes in I was coming down Hairy Hill I went to change gear and couldn't find any. I made the decision to get off the track as soon as possible, I didn't think I would make it round paddock bend and to safety so headed for the rally cross track. This unfortunately destroyed the front splitter and ripped off and destroyed one of the brake cooling ducts. For the rest of the race I was entertained by the marshals at paddock bend watching the rest of the race. Once I was recovered back to the pits, I found I could engage gears again ???, not wanting to risk it happening again I pulled out of the John Taylor handicap :'(. Hopefully it will be fixed for Mallory . http://www.youtube.com/watch?v=NLZkQne_ysY raf practice session | ||

Expert Posts: 2230 Location: Ripon, North Yorkshire | Here's my very short race in car footage - crap start, moving through the traffic and then no gears : http://www.youtube.com/user/jasonrl19#p/a/u/0/wf7wSsOmXxI | ||

 Expert Posts: 8490 Location: Midlands | Just looking at your front suspension set up... are you mounting into the standard GTi shock mounts with the coilovers? If you are I would watch out for the inner chassis legs cracking in between the spot welds... ive seen this happen with just over set dampers let alone coilovers. If you look at how the front chassis legs are constructed, they really arent designed to take suspension forces. If i was you i would look at a MGTF subframe change which will also give front arms and lower mounts that are designed to be used with coil overs. Just an observation | ||
