Rb25Det 300Rwkw Where To From Here?

[WMDC35]

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 , 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.

E85 will get you to at least 320

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

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.

This thread is not about traction is it?

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

Yep get a WMI setup, more boost, and retune
