    Rb24 Build

    in Forced Induction Performance

    Posted

    Hey guys, first of all I'm going to clear something up.

    I have a GTS-4 and I have a spare RB20DET AWD motor. I'm not interested in a 25 and I don't want to go 26 yet until I'm ready to get 400kws out of the car. + The starting purchase cost is about the budget I have to rebuild this 20.
    At this stage in time, I'm aiming for over 200 to keep me with a happy mix between street and track out of the standard 20.

    Now, I've searched a bit and have found a few topics, none of which have answered my questions.

    My understanding is I'll need a 26 crank and rods with 4AG-ZE pistons.
    Which bearings do I need to use with this combo?
    What diametre are the 4AG pistons? If they're larger, how much needs machining out of the bore?
    Do the oil galleries line up?
    What compression ratio does this leave me with? And is this okay for turbo (VG30)?
    What does the stroke become with the 26 crank and rods?
    Do the RB20 main caps fit the 26 crank?
    Do I need to change anything in the top end?
    Do I need an aftermarket ECU or is Nisstune okay for this?

    I'm sure I've forgotten something, but if anyone could shed some light on this topic it would be much appreciated. I wouldn't mind having the first AWD RB24 (That I know of. Feel free to correct me to save further embarrassment).

    Cheers, Cameron.

    Wtb: Gtr Brembo Front Calipers (32 V-Spec, 33 And 34 Gtr)

    in Wanted to Buy

    Posted

    Hey all,
    I'm after a set of GTR front brembos to suit 324mm rotors.

    Don't need/ want pads or rotors, but mounting bolts would be a plus although not necesary.

    Any condition is acceptable as they'll get a rebuild anyway unless receipts are shown.

    Feel free to message/ call me on 0422248143.
    Located in Gulfview Heights, SA. Will happily pay for postage.

    Cheers, Cameron.

    R32 Master Cylinder Upgrade

    in Suspension, braking and tyres

    Posted

    I haven't bought any calipers or master yet, as the main reason for this post was to find out what options I have for a master if I went with my initial choice of caliper.

    The brakes aren't "shit", but there is no way I'll get the times I want around the track on standard brakes. + If I'm going to use a bigger rotor, My caliper will need to be re-fit and it's easier to get a better radial mount that will withstand more punishment whilst doing so.
    I currently have ABS, but pull the fuse for track use and I'm now at the stage of removal of the unit itself.

    I'm currently up to about 3 pages of calculations in working out and I'm ready to pull my hair out haha. But so far, I think I'm heading in the right direction.
    Will post up my findings once completed to hopefully give a better insight of the method behind my madness.

    Part numbers are:

    Calipers
    120-8071-L

    120-8071-R

    Discs

    160-7742

    160-7743

    Will also be making custom hats to suit.

    Can be used for any caliper with the same mounting method, and any size disc as the design for the bracket allows the caliper to be mounted as close or as far away as you'd like via spacers. Intially this was to save weight but we then altered the design to serve another purpose.

    First of all, I'm at work and on break so I don't have time to read every post in this thread.

    Second of all, I'm currently in the middle of upgrading my brakes to 4 pot wilwoods with 4x1.75" pistons and running a 325mm rotor. My old man has just finished mounting these exact calipers to an rx4 and is adapting the mount to suit my GTS-4 (I believe the knuckles are the same as a GTR?)

    Can definitely make up more with some EOI beforehand.

    I tried to google what master cylinder I had, but there's not a great deal of info on GTS-4s anywhere.

    Will BMxx be stamped on the BMC somewhere I can check?

    Although I could google the bore sizes of the master, it still leaves my initial question un-answered. Just because it's an available option, doesn't mean it's better than something else out there. I was more so after opinions, advice and feedback on what masters people have used and how they rate them.

    Diy Yourself Wheel Stud Replacement

    in Tutorials / DIY / FAQ

    Posted

    I also just used ARP WRX studs on my GTS-4 hubs.
    Fit straight in, but I used a solid tube with a hole drilled in the middle for the hub to sit on/ stud to sit in, so they pressed in straight. (I was using a hydraulic press rather than the tightening nut procedure).

    I have pics somewhere, let me know if you want to see them.
