Nah dont have forgies.... Running mobil one synthetic 5w-50... maybe a little on the thin side?
Could be just some piston slap - if it gets better when warm - probably don't need to worry
I use a 10w-30 for mine - copes very well on the track
You can get a Mobil one 10w-40 I think - bit more exy than the 5w-50 but meant to be better fot turbo cars ...
which oil to use ... now that's a good thread to start up

Hello
Over the last day or two I have noticed a very load rattle that sounds like it's coming from the front end of my engine.
The noise only occurs when I apply throttle or when I start the engine cold and its idling around 1000rpm. its a very load 'tick, tick, tick' sound. As I apply more throttle the noise gets louder.
Have you run the engine really hard lately - or overboosted it?
Are you blowing smoke?
Have you lost compression in a cylinder?
Hope its not serious

My 33 has a rattle when cold at about 1700rpm, the noise dies away as the engine revs past this point. The noise also goes away when the engine is warm. Similar problem or just rattly valve train when cold?
Snake - do you have forgies?
if so - then it is just the rattle of them until they warm up and expand to the cylinder bore!

Sly, a "super" high flow is basically a straight thru pipe in a cat housing with no internals - sounds like that's where you started b4 u put on the high flow cat .
If the engine needs to breathe, u will usually see about 10kw difference between a straight thru and a high flow
Don't know much about RB25's, but u could be right that 2530 is too small - hence exhaust flow problems
lets face it, 2x 2530's on RB26 is magic for 300 - 350 kw applications
good luck with the continuing developments - sounds like u need those bigger injectors :-)
