installing a turbo charger on RFX - for knowledge

to add another thing
my engine has a compression ratio of 1:9.5
the ct engine has a ratio of 1:8
is the difference that big?

I still cant understand why people buy a car with the awful XU10J2TE lump let alone want to covert a normal XU10J2 lump to low pressure turbo spec

The only time the XU10 should have a turbo attached is when its an XU10J4TE & the lump is under a 405 bonnet & its a T16

The again I cant see a XU10J4TE running very well on LPG

I would expect that there is more in terms of differences than just the compression ratio. When other manufacturers have had turbo and non turbo engines and in fact turbo engines with different power outputs you get numerous detail changes to cope with the increased stresses and temperatures. Valves and valve seats may be of better quality materials on the CT engine, it could have stronger / more substantial pistons, connecting rods and crank, the cooling arrangements will be different, the oil pressure may be higher in the CT, the combustion chambers in the head could be different shaped, the valves could be different sizes, fuel pressure and injectors may be different etc.
