ah right right, do gtr injectors fit in the std rb25 fuel setup and would i need an ecu if i upgrade them? i know that with the rb30's its u haveto change the ecu if u have the injectors. But im not too sure on the rb25 ecu.

According to HPI stock r33 injectors are only 370cc/min and as such run out of flow at around 200rwkw.

really???

i have about 200rwkw with standard injectors and the are nowhere near their max duty cycle...

i think they are only at around 70%...i thought 250rwkw was achievable with standard injectors??

also dont believe everything you read in magazines, rather talk to people with experience...

aren't SR20 injectors side feed as well?

Yes, SR20 injectors are also side feed. You will need to buy larger Sard/Nismo/Bosch/Denso injectors if you want an upgrade as there is really no standard injectors that are an easy side feed upgrade.

I thought I read S15 injectors (side-feed) were a straight fit on R33 GTST? They aren't 550cc but they are higher than r33 std 370cc, maybe 470?

Also GTI-R SR20 injectors are top-feed and some side-feed SR20 injectors are only 370cc so same as R33, so if you go sr20 make sure you get the right ones.

Well how much power are you chasing?

If Jetdat is right then you can get 250rwkw with std injectors.

The most i can get in standard from, standard being ecu, bottem end, cams. Maybe around 200 - 250 rwkw. Ultimately in the long run around 300 350 rwkw using a 35/40 and maybe rb30 bottem end rebuilt with steel rods and forged pistons and a good set of cams.

    • So either way it is gearbox out and look what is wrong?  I know about the input shaft bearing. Even before swap/new clutch the it sounded exactly like this: So is that inout shaft bearing or the other was installed backwards?  And can some please tell me the part number for that input shaft bearing? The gearbox is small box from R34 N/A and number is FS5W71C. Thank you  
    • I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'  
    • D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.
    • KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.
    • Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.
