Just got my JL EVO3 Tuned and I intend to run it on a 16% fuel. Since this engine is shimmed with 0.3mm for 30% fuel, what would the correct shim for 16%?

It should be shimmed at a total of .20mm. (take off the .1mm shim)

I have a friend in Asia who wants one, but don't know where to buy it, where in Asia did you buy your JL Tuned engine?

Motor looks hot though. Anyone ran it?

For those not in the know. Shimming the liner effectively increases exhaust timing, and port timing. What you will gain is more rpm in the motor and a shift in the torque curve to higher rpms. It will also help smooth out the bottom end abit. I'm not sure on the evo3 tuned version if they changed the crank timing. It's pretty aggressive already. Shimming is alot cheaper than actually re machining the liner.....or carving up the piston. Those that do add shims to a liner MUST reshim the head. Raising the liner will reduce compression of the motor if all the standard shim are left in place.

It's actually a smart way to do it, as you can adjust your timing anytime you want to! we can call it a "variable/adjustable exhaust timing".

The JL "Tuned" are already shimmed for 30% out of the box.

That is no shim, they only did cut away a small edge so the rounding inside the crankcase will not be in the way for a correct fitting of the sleeve.

Raising the liner does increase timing...but it raises the boost and transfer timing much more then it lists the exhuast timing... lifting the liner may raise the boost timing lets say 10 degrees but its only going to add 2 degrees to exhaust, which is going to affect blowdown timing ..... I guess its a cheap and easy way to add a little punch to a motor, but its not the same as actually cutting the ports manually
