Hi all,

I'm thinking of installing an hks 25/35 and I was wondering if anyone knew any max stats/specs with it running on a rb25. I'm also planning on the following mods on top of this turbo.

- Greddy Plenum

- Q45 throttle body

- 740cc injectors

- Nismo fuel pump

- Oil cooler

- A bigger intercooler

- running the engine using a djetro management unit.

- A couple of other mods (cams etc)

I know this is an open ended question but any help on this particular turbo would be a huge help.

Cheers.

this is not a good way to start on these forums, try searching, any turbo that can go on these cars usually someone has already done it or researched it and there is a post on here somewhere about it

I was running a hks 2535 and as its only rated to 340hp (I did to get up to 370hp on dyno but tuned it back to 340hp) I think the other mods your are conisidering are an overkill for that turbo. I have 555 injectors, Walbro Fuel pump, Custom dump with 3" cat and exhaust, Adjustable exhaust cam gear, Pod filter, Front mount intercooler, and PowerFC + Boostcontroller running 1.2. Aftermarket Plenum only starts to help once you hit big HP 400+. It will not help at all with this turbo. I have tried one and it made no power diffrence. Other peoples opinions on this would be a good idea but this was my experience. Once you go over 400hp you need to start doing internal work to the motor so a hks2535 @ 340hp is a safe number for a daily driver.

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
