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.

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:

      R34 manual conversion speed signal wire finding, need help

      By GTSBoy · Posted

      Yes. Autos typically work from the speed sensor on the pinion shaft of the diff. I also think that even if you have a proper speed sensor for the bog manual in the manual box, that the signal it outputs is not compatible with the auto dash anyway. You should consult that manual (the book, not the gearbox).

      And I just realised that that advice is slightly nonsensical for a GTR, because you need 2 of them. But it is otherwise true.

      Duncan's V37.......race car?

      By Duncan · Posted

      Having had a reasonable look at the car, I'll be able to remove the (one time) rams and retract the hinge (they are held in the down location by a tiny (m3?) sacrificial screw) which will get it physically back in shape. From there if you remove the rams you need a resistor to turn off the airbag light (as Mark said, there are plug in kits and I might go that way because its reversible). And...per all the threads on here, even if you have the resistors to turn off the airbag light, the bonnet light will stay on as it writes to the airbag computer history - that is either replace the airbag controller, reprogam the EPROM (if I can work out how), or remove the globe from the dash. Having seen how sensitive this system is, if I had my time over I'd pre-emptively remove the rams, even on a road car, because this is all a very unnecessary pain in the arse. Reminds me, time to go and have a look at the Fuga too....
