Some people will say no and some will say yes. You will see different performance from both with the difference in the cranks. It will usually make the engine a little more efficient on fuel and also give better performance over the power band. But will it be a night and day difference I think that depends on the persons ability to use the engine to it's ability as well and all the other issues. The pipe and clutch will also make either one run well.

anyone tried a shim under the sleeve (like the red dot tuned) in their idm evo3?

I'd recommend the 2617 pipe after you shimmed it.
if i add 0.2mm under sleeve, i got to remove 0.2mm from the button head right? to have the same head clearance...
Btw, I am using head shims of a .26 GO engine. These shims have an inner diameter of 17.2 mm. Our engine (Picco & Nova based) sleeves have an outer diameter of 17 mm. The won't fit on Sirio, there sleeve OD is 17.5mm.
I cut the outer rim of the shims with lexan scissors.
There is also a RB 323/523 engine which has head shims with 17 mm ID, but it's a bit of a tight fit.

no worries about the sleeve shim, i got 1 just for the picco.
higher consumption = 30s less runtime?

time for new P/S and button?
stefan: i'm using the sleeve shim from my old tuned nosram.12
did an engine cleanup and observed the following (see pic).
time to ditch the engine? or replace new P/S and button?
caused by over-lean? i suspect caused by foreign debris...
