so guys basically ive got an rb20det with hiflow r33 turbo, full 3" exhaust with stock cat. no boost controller atm as im looking for the right sort. it has a jun tuned ecu which i was told through jun is removed speed limiter, raised rev limiter and modified fuel ratio. it has aftermarket coil packs and pod filter also. ive got a front mount going on next monday and im trying to work out basically what is needed for the tired 20 to push 300kw. i know it will probably need a bigger turbo set up. im currently in the market for gtr injectors before i raise the boost.

so what shall i do? anyone have any 300kw rb20s? how do you do it without to much muching around. im also aiming to try get things compatible with rb25 for when that day comes.

Why did you post this here?

1. you'll "probably" have to change the turbo? haha. You'll need a big turbo to get close to 300kw from a 20.

2. If you do indeed want 300rwkw then I wouldn't even bother with GTR injectors 442cc is going to be too small.

3. It's going to make absolutely nothing before 4500RPM+ and not be very nice to drive, at all.

My tip? Start with an rb25 because you'll spend all the money you need to get buy a RB25 and get it to 300rwkw to get the RB20 there and you'll just be disappointed.

If you are happy with 220-240rwkw, then that's the max you should try for on an RB20.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
