Not enough oil pressure from hydraulic lifter gallery(being low pressure, as opposed to getting feed direct from main oil gallery).

I think the internal vct mod is a bit of a hit and miss some say it works others say it doesn't.

All I can say is that it didn't work for me, and its a head off job to drill and tap for a vct feed line.

Take a risk and find out if it works for you :P

it's not worth the trouble If it may not work external is proven to work

So you ended up wanting to go the 35R? What made you change your mind? Just curious...

Ive currently sold my GTX and just purchased a 35R to throw on there.

currently she only revs to 6500 rpm as anything over that it just stops making power, though still enough to run a 12.1 on 18 inch ling longs.

With the 35R on there I can rev it just that little bit harder and gain that extra 1000 rpm. +fix the vct issue and I am back to where I started in terms of response.

Its win win, fix vct and get similar response to the gtx without vct + have that extra 1000rpm head room to get down the 1/4 quicker.

      R34 Skyline climate control unit transistor

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      I think Fitmit had some, have a look on there (theyre Australian as well)

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.

      Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
