Hey, have an unopened r33 rb25det with 300rwkw, looking for a bit extra, maybe 320-350, debating whether to do rods & pistons or rb30, or just crank boost for 320ish and see how long it lasts :unsure: , it's a road car, whats your thoughts? anyone thats run around 320 on standard motor-how long did it last and what did it get used for? the engine i have is on about 81,000ks and seems mint

how much faster on the road is a 30 than a 25 with the same/similar kw?

cheers!

Need more details, turbo, fuel, boost level, dyno sheet would also help.

Quick answer is yes an rb30 with the same peak power as an rb25 (both done properly) will be a lot faster on the street as the area under the curve will be a lot more.

Crank the boost! You will surprised how long it lasts for with a decent tune, but eventually it will let go :whistling:

In terms of RB30 vs RB25... It really depends on too many factors, some RB25's will be faster, some RB30's will be faster

Add boost until it stops making more power, then a couple more psi so you don't lose power on a hot day, then add some more to account for lower pressure at high altitude in case you drive to the snow next winter.

someone posted a video of an RB30 with a simple bolt on blowing a CBR600 on the street recently

id say RB30 is awesome on the street...... but yeah,

need more info re the current setup as stated. could chuck a WMI setup in and screw heaps more boost into it

      Sounds like it is rotational in the driveline. CV? Tailshaft CB? Also.....didn't you just pay to have that bit painted and put on the car?

      R34 GTT idle problem

      By GTSBoy · Posted

      Yeah, when I dialled my idle down, given how much time I spent idling at the lights in traffic on my daily commute, the effect on overall fuel consumption was absolutely noticeable.

      Emissions, fuel consumption, heat, noise, etc. most likely.

      For me at least the reason why it bothers me is because it's indicative of a deeper problem. And that will nag at me forever. Especially because I have tailpipe emissions testing + evap leak testing every 2 years.

      WELP. I went to the track, and I suppose it went okay because any time you can drive home is okay. You may notice the car is not on the circuit in this picture. It was about 35C day out in Benalla which means the track was approximately the surface of the sun, probably. Good things, car did not overheat but it _was_ warmer than when I had done track days in similar heat before, I think, I'm not sure - I can't quite remember. Coolant got to ~105 via the ECU after 20-30 minutes of belting it in said heat. Oil got up to 145C in one instance which is pretty crazy due to oil cooler. Pressures were fine. I seem to remember this not getting quite so high before the vents. More HMMMM'ing to be done. On the subject of HMMM'ing, can anyone identify the sounds in the video below, you will know which ones I mean: https://www.youtube.com/watch?v=uj3BkI2cbTc I included some 'normal' sound as a reference for the first minute or so. The microphone in this instance was where the license plate is. It stopped working later in the day which is why my "best example of a lap video (not produced)" had internal audio - Isn't hearable from inside the car. I don't mean the chirping of the un-bedded/badly bedded track brakes which you can only hear while braking... Thoughts, brains trust?
