Max Horsepower Of An Hks 25/35

[Clintox R33]

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.

Great turbo, great response, as mentioned above the 740's are overkill....good for someone looking ata turbo that doesn't have much lag associated with it, yet can still deliver some nice streetable power.
