Hey everyone,

Part of my R33 mods involve removing the factory Speed and Rev limters (i.e. using ECU piggyback). If i allow the RB to rev up to 7500-8000rpm what should i be aware of? Obviously the engine will wear faster, but will i possibly bust something on the stock engine (like head gasket) or is it something not to worry about if it isn't thrashed often?

Thanks :wave:

Increase in engine speed, increases engine stress to the power of 3.

You have listed no mods, so assume stock cams, head etc, which will keep your power pegged at mid engine speeds anyway.

Rem to post pics when it fails hehe :P

rev it to 8000 at your peril.

:wave:

Lol thanks for totally raping my question hehe. That's why i asked, before i made any decisions i needed confirmation whether to leave the limiter!

Thanks guys, you might have saved a blown engine.

    • I used to have Walbro 255's when they were a pretty common update. (or were they 044? 040?) In any case I had a dirty tank. I thought the tank was good, but I would find the filter would clog in maybe ~50km of driving. If the issue persists, well, your fuel system or tank has crap in it that the pump is sucking up.
    • Hi. Ok thanks for the info. I/we do not know what tune is on that Nistune ECU so it is why there is stock ECU and that Nistune is for later when the car is done. I have guy who tunes Nistune and other ECU so i will then take it to him to see and properly tune for the car   And for the update. On 99,9% it is bad fuel pump. Which is wierd cuz it is like 2 years old(brand new walbro 255) and that filter (also brand new) was dirty.  I was alwaya pumped premium(100) on very good petrol station so i dont know how is that possible...

Don't mind to spend for a decent quality  Thx  
    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here
