low comp pistons on N/A engine

[13"rims]

right probably really stupid question, but can a naturally aspirated engine be run on low compression pistons? obviously there will be power loss, i'm just thinking about preparation for a turbo conversion? yes its a ridiculous question

 

[Gmk1]

dont see why not... may make the car slower though (unless its got turbo to boost)

wouldn't cause any long term damage would it? just fuelling etc would be different?

If you didnt re-map it, it would cause damage by running really rich.

ok, all sounds good then!

does running rich dammage the engine? i kow running lean is too hot and definately does damage. but i thought running rich just meant poor economy and unburnt fuel out the back, or is it the cat that is damaged?

Running rich is no good for the engine either. youll get bore wash etc! it can damage alot of things if its running very rich.

so you just need the fuelling reduced? guess timing and ignition would possibly need altering so its runs smooth (as smooth as a N/A low comp engine can!) could use 95RON fuel too?

why not just wait untill you fit the rest of the gear

fair enough, makes sense. so it would strip the oil from between the rings?

Just build the whole engine and drop it in don't even bother trying this one job at a time idea.
