Hey 9k, any updates with the T618Z's? I'd love to see any results if you have them.

Cheers

Justin

very very nice mate. mine is off getting a rebuild at the moment. running t517'z aswell. justwondering what your best power figure was on wht boost with the 2.6 and t517z's. was it still capable of decent response? ive found mine to be abit sluggish but thats with no cams/headwork and factory bottom end untill i get it back

Not to hijack 9k's thread, but in answer to your question...

I made just shy of 400rwkw with a pair of 10cm T517Z's on a 150k bone stock 26. They wouldn't make any more boost than 24psi... even with the actuators wired shut. That was 5 years ago. The numbers were backed up with 136-138mph mid 10 sec 1/4's. That set up lasted nearly 2 years.

Bolt on's only... even the stock exh manifolds were un-ported.

Serously, keep the re-build simple if your staying with the T517z's. Stock- block, crank, rods- all prepped correctly, good oil pump, clean up the head and a 260deg drop in cams.

GL

Justin

    • Wow ELVIS. You have an....interesting approach to conversation. Did you not notice that I wasn't talking to you?
    • Hello Liam - HA - somewhere in flies - possibly I have an update, but I have been so busy, projects have taken a back seat to getting business back on track.  I will let you know the outcome, but I think I am going to go for the 8HP,  CHEERS.  ELVIS
    • Thanks Joshuaho96, yes - as someone else also suggested, the 8HP seems the 'smart choice' - HA - and ZERO to do with cost, but I am sure 8 speeds will be better than 6 speeds - HA - maybe.  I will purchase a new 8HP,  Thanks.  ELVIS.
    • Nobody said anything about getting a "...cheap Falcon box..."- it was JUST a question about a specific transmission.  And YOU may have a problem with not enough $ - HA - I do NOT - so please keep your comments like you are some financial guru to yourself.  BUT - much appreciated re the cost of a new 8HP and I twill probably be the way I go.  Thanks.  ELVIS.
    • Most people I know in the BMW world are swapping 6HPs for 8HPs. The 6HP has a big issue with one of the clutch drum bushings wearing out shockingly early which leads to them going into limp mode going into 5th/6th gear as the oil pressure loss from the worn bushing causes clutch slip. Even with the adaptations in shifting the TCU can't bump line pressure enough to keep the clutches from slipping and burning. I've personally looked at a 335d with 6HP28 with one owner and ~90k miles on it and the transmission adaptations were way out of spec and even though it nominally drove ok I'm confident it would have needed a full rebuild sooner than later. Other than that they're fine, but the 8HP doesn't really have weird issues like this to my knowledge and they're in everything these days so pulling them out of crashed cars isn't too hard.
