hi i'm thinking of selling the cossie and buying a mk1 focus rs. what sort of power increase will you get for how many £'s. at what point do you need to uprate the internals/change turbo?
first thing will be a front mount intercooler fitted as i've heard something about the pumps packing up in the chargecooler

thanks Billy

 

the norm is remapped,exhaust/decat.tubular manifold,gen 2,forge adjustable actuator and forge recirculating dump valve,should see circa 300 with this,turbo change will see 300 plus easy,though id recommend upgrading to ap six pots aswell
best jumping over to the frs section on the rsoc and youll get all the answers there

 

thanks for that what power would you get from exhaust, decat, filter, intercooler, bluefin/dreamscience

 

can be anything from 260-300 dependant where you get it rollered.id leave the intercooler and keep the chargecooler as its actually very good,my acts dont creep by 30 even on these hot days,intercooler is only needed if its tracked,get a tubular exhaust manifold instead.and id recommend "tuna" instead of bluefin/dreamscience.go on the rsoc on the foucs mk1 section and youll get all the info you need
