In the process of an rb20 s13 silvia conversion. My main goal is to get best times with least mods. What im asking is that the people with rb20's post their mods, times and hp/kw at the wheels. I'd really appreciate it as it will aid me in not going down the wrong track when it comes to modding my car.

Thanks

Jase

I have a stock RB20

Fitted A TO4e to the stock manifold with a turbosmart gate

600x300x73 front mount

full 3'' exhaust

044 bosch fuel pump

z32 afm

tuned std computer with stock injectors

made 234rwkw

Ran a 13.4 @112.3 mph this was with slow 60ft time(2.3) as i took it easy off the line full ran with street tyres at 30psi. Fitted some sticky tyres and the gearbox didnt like it. So i expect a 12 second pass once i fit the 33 gtst gearbox.

im doin the same... bought a s13 with rb20det.. so far its got 1 bar boost (std turbo) reco lsd, big fuel pump and reg, 3inch zoorst, clutch and boost controller.. im hoping to get into the 12s.. im thinking get a vl t3 cause they bolt on and just get that high flowed using t04 internals maybe different compressor housing?? also fmic, cam gears and then maybe computer.. if i can get tractioni mite get lucky... the guy im buying it off thinks that with traction a 12 would be possible as is!!! not too sure about that.. guess ill find out when i get it! probably best geting r33 gtst gear box as well.

    • 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?
