if u google castlemain rod supercharge rb30 u can find info, i seriously contemplate this with a 4agze super charger from toyota ( its self sufficient) for oil and just fabbing up a airbox with inlet for turbo and supercharger, than having it wired to a rpm activated switch (its a clutch based supercharger) and place it right where the ac compressor went, hardest part would be aligning the bolts and mating it to ac bracket

http://cgi.ebay.com/ebaymotors/JDM-91-97-P...sQ5fAccessories

thats the unit, minor wiring fabbing, and belt work ( lets say 1000 if u can do it your self)

.....of course nothing is that ez

That will give heaps of torque and much quicker response...interesting...now i am really considering that as a mod for my car... :devil:

700awhp @4000rpm :P

So it probably goes alright then.

ya i bet...but it peaking at 700hp seems to be a bit less for a quad induced car though....imo

Well power has nothing to do with the number of turbos or superchargers you have, you can make 1000rwhp from just a single turbo. The point of the quad charge is self explanatory... Peak power is at 4000rpm, and I bet those turbos wouldn't be working as hard as a single to make that power.

Don't forget that when you supercharge, you have to sacrifice power to make power.

    • 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?
