found out that with the shortshifter i couldn't find reverse, 1st and 5th gear, so had to modify it slightly and now all gears are solid and with only minor movement from the hand
installed the extra gauges and wired them up
i wanted to redesign the gauge box on the dash, and the rest of the dash so i thought the best way to keep me motivated to start on that soon was to bolt the rusty thing directly on there, so it will annoy me every time i drive it
after that i had to wait for an turbo oilfeed connector wich arrived friday and an hour later i fired it up. started right up with no leaks whatsoever, all great. i allowed it to warm up at idle and did prechecks and stuff. first testdrive on partial throttle went smooth, feeling way more powerfull than the old setup, even at very low revs. i allowed the car to cool down completely and after that the second testdrive, oil up to running temp and i tried out the turbo but... no boost and a loud whining noise! a bit confused and fussed what it could be i tried a lot out. externally pressurised the IC system to check for leaks; none. removed wastegatehose and did a testdrive, no more than 0,1 bar so hosed the wastegate back up.. drove home to do a checkup when i noticed the noise was suddenly gone; i gave it a bit more throttle and got 0,5 bar boost. car accelerated as a rocket
dumpvalve enjoyed it as i was changing gear; halfway in 4th gear the boost dropped and the noise was back. knowing something wasn't right i decided to give up as with every minute "testing" the damage would become greater, wasn't happy about the whining sound..
today i took the turbo off in the rain;
and on the last nut i made a mistake, used the wrong wrench.. so i f*cked the nut up and manifold + turbo had to be removed to get it loose.. was a bit tricky as i had to move the intake manifold 1,5cm off the head; raise the engine 2,5cm and then i could pull it out...
after i finally got the nut loose i took a close look at the turbo
it looks like an unbalanced shaft / too much play on bearings / bended shaft causing both compressor and turbine wheels to scrape the housings.. i've contacted a few sources and decided rather than just a new centre, order a brandnew turbo, same model; GT2560R ballbearing but boxed and brandnew with warranty. quickest and most reliable solution at the moment as it HAS to run next weekend at the Elandrun circuit. this will eventually get a checkup to see if a new centre will be enough, if so. it will be the base for a next quick & dirty side project
