I made a start on cleaning up the housings.
But while cleaning the exhaust housing I found 2 hairline cracks.
I phoned about 5-6 different turbo refurb companies to see if I could find a replacement. They either wanted to sell me a complete turbo or couldn’t find a replacement turbine housing. As no one makes them any more and our Chinese friends haven’t copied them either, it left me feeling a bit lost what to do next. However I did get a recommendation to speak to Vince at performance turbo as he is a bit of a cosworth turbo specialist. He reassured me that the cracks are nothing to be worried about as they pretty much all crack there and won’t effect it in any way as they are on the first radius after the flange. So with that knowledge I’ll finish cleaning it up and run it anyway.
Im still considering welding the standard wastegate up and using a tial 44mm external gate.
any way back to my issues with trying to get crank sensor sync.
Ive run some trigger logs and it looks like it’s occasionally missing the gap on the 36-1 trigger wheel on the back of the flywheel.
So I whipped out my eBay bore scope and poked it in the crank sensor hole to have a look at the trigger wheel.
now to me (I might be completely wrong and barking up the wrong tree) it seems like me442 is very sensitive and is picking part of the standard DMF behind the trigger wheel.
I tried spacing the sensor out with washers until it barely reads all of the triggers but that caused other issues with not being able to use filtering for em frequencies.
So for now I have another crank sensor on its way to test if it’s just that. I’ve also ordered a TTV flywheel but they are out of stock at the moment so it might be a couple of weeks before that arrives.
In the mean time a few other bits have turned up. I know I said I’d do it properly and put forged pistons and rods in but after doing A lot of research I think I can get away with doing it dirty haha.
What will be quite interesting to me is seeing how well this friction plate will work. It’s a hybrid from CG motorsport that has a organic disc one side and 5 puck the other. It’s supposed to have a large torque capacity but the usability and feel of a standard clutch...
so this weekend I think I’ll have a bloody good tidy up round the ramp and start pulling the engine out
