I always thought running flat tops means u can run more lift.

comp ratio going to be around 7.8 to 8.1

reason that low comp - less pinging high boost ,

makes more power then high comp - all types of fuel

I notice a lot of high comp boost rb have head/studs lifting issues

allways prefer low comp high boost/ high comp low boost

I here'd about weathering/seasoned blocks are better for hp than new block for cast iron - new block will move and flex up until 100,000km

Idea is the hot and cold temp stop the cast iron from expanding/ flexing - taxi blocks would be good idea

I left the rb30 block outs side for 6 months bare wit the girdle and just befor sent to engine shop I went to cryogenics

I believe this theory works , some might disagree

crank wouldn't think be any benefits

only cost $200 shop in melb -http://www.cryocycle.com.au/

    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
