My RS has an 1800cvh bottom end but I have been told it needs different pistons which ones should i get and how much? Cheers

 

1800cvh is not a very good engine for power to start with. I can't recall why they are not but I just remember a big discussion about it and that the 1800 is not that good when it comes to power/producing it/holding together while producing it.

 

LOL, the guy asked what pistons, not what u thought about his 1800 sierra lump LOL

 

Sorry!! I don't have any thoughts on the engine!!

As far as I recall from the discussion, there are very little options for pistons if any at all.

 

Yeah, ive heard the options are limited, might be worth finding pistons from a diferent turbo car, MR2 or sumthing, i dunno, its amazing what pistons u can fit where if u now a good engineer
