Stupid question from someone moving from electric touring cars to 1/8 Nitro pan cars ,,
With this motor straight out of the box can I use 25% Nitro ?
Also what glow plugs will I need in the tool box ?
What is the deal with head shims ? Should I just leave that shit alone ?
Thank you in advance

When using this engine in a 1/8 Pancar you do not need to change the headshims because you will never be able to use all the power available.
I personally think this engine is overkill for a pancar and you can do with a less expensive engine, unless you just like to do this

Hey guys ive been running 16% from new, done about 4L. Want to go 25%, should i change anything or just re tune to suit? The engine is stock..

It would be a good idea to add a 0.1mm head shim when going up to 25%. The engine might not need it but best to play it safe and add the shim initially and see how it goes.

23731000 has a black protection and normally used for the on-road engines.
23731000 has a blue protection and normally used for off-road engines. The blue protection is a little tighter on the inner-ring so seals a little better.
