Going back on the dyno after my 210rwkw read out on 8psi 2 weeks ago...

Could only run 8psi because the wastegate actuator was only holding 8psi.. now i fitted a aftermarket 14psi one and raised the fuel pressure up a bit...

Specs

RB30DET 25/30 Hybrid with all Stock 25det injectors / setup

Stock Internals

AVO Stage 2 cooler

3"

PFC

Malpassi

rx7 / t4 hybrid turbo

Im thinking the turbo has lots of room for more power if it made that reading at only 8psi ???

If it ran 210rwkw before on 8psi wonder what it could make now :mad:

Anyone have a similar setup with power figures?? will post a before and after dyno read outs

yeah u should be able to get that

stock inj have been used up towards 300rwkw reliably

you cant be serious about this ?

Stock 370cc injectors to make 300rwkw ??? how is that possible???

Sure 300rwkw could be done but the injectors will fail at some time breaking your motor.

Why do you think there are so many rb25's that run stock injectors and break once over the 240-250rwkw mark.

Look at the reliable RB25's that have held together.

Freebaggins 280rwkw is an excellent example running bigger injectors.

Guilt-Toy,

Do you have a boost leak? or is your Bov Venting?

Have a listen and watch the boost graph while on the dyno.

No boost leak or anything... it must be a waste gate controll issue... running a bleed valve.

You are right. In the morning i am going to put the boost down to 8psi and save up some more pennies for injectors...

Would GTR injectors be good enuf ?

Bleed valves are known to bleed down at high rpm.

Generally they will only hold ~2-3psi more than the wastegate can handle.

Either redrill the holes in your actuator bracket and make it an adjustable actuator :D or get your self an EBC.

I went with the redrilling of the actuator bracket.. Works well, takes a little fiddling though.

    • Haha, i kow right? Could have bought so many cars for the same amount of money (or less) but driving Unicorn gives you at least +1mln to style 😅. Like wise man said "life's to short to drink cheap wine and drive boring cars" 😉
    • Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny  
    • Hey all  im wondering if you can help me please I have put a rb20 box in my r34 gtt as my auto packed up and a friend had a spare box I know it’s not ideal but it will get me up and running for now. we have done the conversation and everything is working great but my Speedo we got a s13 speed sensor but my Speedo reads double now and I bought a speed converter but still not having any luck.  so I thought I’ll reach out and pick your brains  any help would be appreciated please as I wanna drive my car again 
    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
