chrsito as others have said dont stress about the head gasket. I have the same turbo just externally gated on a high comp motor (193,xxx) with standard everything internally and im on 18psi... gets some hair on the goulies and get the power up:)

I've got a Garret GT3071 (smaller than the 3076)on my R34, and I get 260rwKW at only 16PSI, and the response is just as good as the factory turbo. Next I'll be putting the boost up to 18PSI with the hope of getting about 280rwKW.

just as good as factory? all in under 3k?

Edited by Mattw_83

Asking if it is all in by 3k I am assuming you mean is it on full song by then. Meaning full boost, peak potential for flow, etc etc etc etc.

Consider for yourself, how can something that is going to be maxed out by 3000 RPM going to be good over the range? Well, its not really.. That's why we all bin the bloody thing. I binned the whole anchor of a motor to be honest, and that chewing gum gearbox.

Now if you consider a turbo with a higher flow potential could get you better power up top, all you need to do is have it flowing good power in other areas where you need it. That means while its not on FULL SONG or FULL BOOST by XYZ RPM its still making plenty of flow to actually make GOOD usable power.

Welcome to the wonderful world of turbo selection, and the f***ing terrible one of working with a 2.5L (to which I still have, DOH) >_<

    • 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... HTH
    • 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?
