Hi

Please dont flame me for starting these threads but i'm a bit stuck as to what mod i should get next. Obviusly i want the most gain in power.

I will be purchasing either a profec A ebc or a safc II next week but will only be able to purchase one at this current moment

Current ride is a r34 GTT with a full exhaust and a pod filter.

I'm looking at boosting it to 10psi and occasionally to 12psi for quick squirts (is there such thing as 11psi or is it even increments?). Is this ok for a gtt on stock IC and turbo? Will i experience any substantial gain in upping 2/3 psi boost?

SAFC II

well i guess this speaks for itself

i think the safc II will be the smart "safe" choice but wat are your thoughts on an ebc?

what other mods do you have?

I initially had full exhaust, FMIC, then I boosted it to 10 psi with the norgren 2 valve + check valve system which cost me $150 intotal to build.

The car went like crap b/c it was overfueling on 10psi boost.

When I got my SAFC2 and tuned it, my dyno chart showed 200rwkw at 9psi, and the car felt great. Not just power, but driveability and smoothness made it so much more enjoyable to drive.

Now I have an R32 wastegate actuator which I picked up for $50. Hold 10psi of boost better than any valve or EBC. If I want more boost, I can wire up the standard boost solenoid to a switch, and that doesn't cost a cent.

if you just want 10psi boost on the standard turbo, dont waste your money on an EBC, just get the RB20DET wastegate actuator, and get the SAFC2.

The SAFC2 is the best value for money mod on an RB25DET (or the jaycar kits - same thing)

cool thanks for the response

yeah, i'm goin to buy the safc today as the guy is selling for a good price =)

would a rb20det wastegate actuator work on a rb25det neo?

might have to look into this as well so i dont waste the tuning

      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?
