The SR20VE we got has a small coin stuck to the side of the head, has KERZAN written on it. Any ideas what the meaning of this is! We bought the engine from autoparts chch and it was an imported engine from jap land.
I found them but dunno what they would have to do with it, all the original liquid gasket is there, engine hasn't been apart from what I can tell.

that's the extent of my input.the site seems to suggest they might do quite a range of stuff - maybe they previously had the engine!

aren't they the little indicators which show if the engine has been overheated or not! I know some engine builders put them on engines they rebuild so the warranty can be voided if they can prove the engine was cooked.

Good point, and they do indeed sell them.
Edit to say it's possibly been installed by the second hand dealer so they know if the motor's been fired up!

I just emailed Kerzan and will let you know if they come back with some useful information

It is an overheating indicator. If the engine is cooked, the glue melts and the coin drops off. No coin = no warranty.

a quick google of heat tabs and yes thats exactly what it looks like. What sort of temperatures will these get set off at! its on the exhaust side of the head so potentially the hottest section

250F on the k-line ones,then the centre falls out.

The Kerzan website had the temps - I was looking at them last night.There is a high temp and low temp version.
