but 1.8 is cheaper and you can use 2.0 litre megane 8v pistons to keep the cost down.
i didnt know that, what would the compresion ratio be using them and would i need one of the expensive thicker head gaskets from BB tunning?Originally Posted by MAXIBOY
Didnt BB tuning always seem to get more bhp out of the f7p on there turbo conversions than the f7r?
Seem to remember observing that somewhere.
Id go for a f7p if i was turbo'ing personally.
compression would be 7.5 to 1. could run a standard gasket. pistons are 40 quid each new.Originally Posted by Rory
yes but as far as i,m aware that was due to different mapping...Originally Posted by arj256
though the 1.8 was tuned to 320bhp.... and might get even more very soon..
i thought that for the high boost conversion u needed the compression to be 8.5 to 1?Originally Posted by MAXIBOY
well how wouldnt want to put too much seeing as std h/g and std megane pistons (not forged) what would be the lowest and highest boost u could run with them?
well there is no lowest as you could run 1 psi it would just be shit but highest ? dunno 10 psi maybe 12? as a rule you cant run more than 7 psi on a stadard compression n/a bottom end
