am building a new engine for my escort and was wanting to no what compression would work best. Am still running a 1.6 and i was wanting to run standard comp so id hav little turbo lag.
iv got wossner pistions and steel rods at standard comp, i would think it would be ok to get the pistons skimed down to low the comp what do uses think. am wanting 300+ bhp
thank

firstly low comp wont give u lag if u spec it right,so use the smallest turbo to achieve the figures
whats the rest of the spec?turbo etc? as u cant ask a question like that and get answers when no-one knows ur spec,and picking a comp ratio because someone told u on the net will never work,spec it right and it will be awesome,mix match of parts and itll be a disaster

i'd personally run around 7.7-1 and put a roller bearing turbo on something like the gt28rs or 2871 as they spool up really quick, not to sure what a gt25 would be like for making 300hp though or even the new roller bearing t3's that are about to come out that jamie is testing on nick's car are suppopsed to be excellent but all the above are pricey
