Hey guys - So I had issues with my gearbox coming out of 4th gear off throttle. My mechanic looked at the joint from the shitter into the gearbox and we replaced it anyway but no change. Then my tuner actually took it apart as he noticed the boot at the bottom of the shifter was gone so that made these quiet again and also stopped some fluid spilling over the top. He also noticed that the shifter had some parts install wrong and fixed this (grrrr at my mechanic). This fixed the 4th gear pop out issue but then I was driving along and off throttle again and 5th gear popped out which it has NEVER done. Now im just confused as to why its changed from 4th to 5th with a correctly installed shifter. Any ideas?

OK so need some help please people just turbod my na r34 and am checking if what it's doing is OK before my tune on Thursday OK so I'll start with parts I'm running... And post problem last Rb25de neo R33 5speed gearbox conversion Was using rb25 one but think was near dead New rb25turbo hasn't arrived yet R33 turbo manifold Gtt injectors R32gtst4det fuel pump Power FC ecu stock gtt base tune atm Big front mount cooler Turbo smart bleed valve New 3"pipe decat and r32 custom dump R34na 02sensor R32gtst4det afm I wired in also tried 34 na one OK so my problem is it misses bad under boost only.. disconnect turbo runs sweet can this be my ign timing when boosting? Just want it all good and ready for my first tune as never had one what should I get done in the tune and what boost 5? And just get fuel/air and some timing pulled/retard etc...also haven't tried yet as my new turbo is on its way but the one I was using was blowing smoke and whining and no matter what it was stuck on 7-8 psi my hand controller wouldn't turn it down so waste gate? Over boost could've been the problem?
