Its Been A Long Time Since I Was Here. Have Another 32 Questions On Upgrades Please Help


Recommended Posts

Hello

It has been a while since I posted on here, over a year. I have read the posts but still need some help. Please help. I live in Japan, American, so not Australia, but dont mind buying parts from Australian stores.

I have a new 1992 R32 GTS-T. This time its a manual. My first car died. I am taking parts off of it. I am going to take the RB25 turbo with the HKS aculator and put it onto the new car.

SO far the car has a 3 inch cat back exhaust, split front pipe, stock cat, Apexi air intake and that is all. I am going to add the RB25 turbo as I mentioned. Should I keep the HKS aculator on it or put the RB20 one on?

I am getting a inter cooler also. Will used ones be fine such as ones from Blitz or Arc or used GTR ones? I can find cheap used inter-coolers here for about 100 dollars.

My goal is 300 hp but now I am aiming for 250 hp to start. Should I replace the fuel pump too since I am adding the turbo and inter cooler? If so than I will buy a after market one rated higher so when I start the big mods I will have it.

What else should I add now?

Are the Emanges' still a good option for tuning later?

Help please

What is the HKS actuator set to? If you still have a stock ECU, it will probably go into Rich & Retard mode (R&R) if it's set to 12psi or higher.

Change pump for peace of mind, it's what 18 years old now, no guarantee it will take kindly to the extra power.

Since you are aiming for 250hp, the stock intercooler will do, but at 300hp, you will need a better one, used intercoolers should be fine as long as the fins aren't damaged and you give it a good cleanout. At 300hp even the R34 stock sidemount is a decent upgrade to support that power, but no more.

The ECU is stock. I am not sure what it is set to. The adjusting screw is at the opposite end 80% from the starting point.

So should I switch to the RB 20 aculator?

How do you clean out a inter cooler?

    • 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?
