4K Motor

Recommended Posts

I just pulled down a 4K and it has the combustion chamber is in the piston.

What modle Corolla had this type of 4K?

This is the first time my father and I have found a motor like this.

Any help would be great.

Hi Aaron,

                When an engine is that olde, all sorts of mods or refurbs could have been carried out in the intervening years, with dished pistons, & maybe a flat head being fitted.

However, if the engine is original, it could be a 4KU engine, which did have dished pistons as standard, & produced a bit more HP, than the more common 4KC engine. 

4K-C   43 kW,      4K-U   55 kW.

The 4KU is not commonly found now, so if you have got an original 4KU engine, hold onto it.

I've run one in my KE30 for years now, & it has been a great engine.

You can check out the difference of all the 4K engines at this link.
