Looking for any info re how this translates into performance - reliability - etc

Looking at a car which has this conversion - does not seem to be a problem as far as insurance goes but has anyone lived with it ??

A Roger King engine is a big plus point as the standard Supersprint engines has one or four weak spots (pistons)

The RK 155 conversion is nigh on bulletproof, will have stronger/lighter forged pistons, a genuine 155bhp and is built by one of the most highly thought of engine builders for the Crossflow.

I had this conversion on my last car. (P840 WKH) It started life as a 1.6l 100bhp, and went to 1.8l 155 bhp by Roger King (4 gears). It was more torquey, easier to drive, and on road running had better petrol consumption. Performance was excellent. I now have an R300, and in a straight line notice very little difference in acceleration up to 70 or so.
