Okay as some may know, I had clutch problems. I bled it today and that solved my clutch issues per se. NOw I have another one. The damn thing slips now. But only in 4th and 5th gears.

Next problem is weird noises when I turn the steering wheel. I know the steering rack and downpipe rub. However mine stopped making grinind noises awhile ago. This noise isnt grinding, it is more liek squealing

Next problem is the turbo. It spools fine and boost fine but when it starts reaching full boost, teh spool ounds more like a yell for help.

My RPM's are still ****ty until I get to around 3.5K or so, then it is fine, but in the earlier RPMs or from a stand still, the car is liek ***. I had twop more peopel more knowledgable than me ride in it today and we had no clue what was wrong. If anyone has ANY insight...feel free to chime in

LOL1.) AFTER YOU BLED THE CLUTCH DID YOU DROP THE transmission AND SPRAY THE FLYWHEEL OFF WITH BRAKE CLEANER AND SCUFF IT? IF THERE WERE ANY LEAKS INTO THE transmission ON TO THE FLYWHEEL IT'LL SLIP.

2.) TIGHT BELT, BELT WORN, PS PUMP LOCKING UP, WET BELT?

3.) ITS HARD TO TELL WHAT IS WRONG, WHO KNOWS.

hmmmmm....

The guys riding with me said somethign about the bel5s too. My PS pump is attached but has no fluid in it. It kees leaking. I jus never bothered to uninstall it. damn I may as well remove it since I can get a non HICAS one from Nismo241. No I didnt remove he transmission after bleeding it, but you know what.......my transmission DID have some kind of fluid on it. I thought it was weird since there is no rain or water on the ground and nothign is leaking. I tried smelling it to no avail. damn I REALLY dont want drop that ****, but I think I will. My **** had mass air bubbles in it. Would that cause teh fluid to maybe go in the transmission???

NO THE CLUTCH LINE IS ISOLATED FROM THE transmission BUT I HEARD THAT YOU MAY HAVE LEAKING SEALS AND STUFF AND THAT WOULD FILM OVER THE FLYWHEEL MAKING IT SLIP. SO YOU HAVE AN EMPTY PS PUMP AND THE BELT STILL ATTACHED? WELL THAT IS CALLED INTERNAL RUBBING MAKING A METAL ON METAL SQUEAL. AS FOR THE AIR BUBBLES IN THE CLUTCH HOPEFULLY YOU BLED THE CLUTCH ENTIRELY, IF YOU DIDN'T IT'LL PUT GAPS IN THE CLUTCH PRESSURE.
