Dont do it!! i went from fp green or pf whichever and a frontmount with 1.6 bar and 330hp atw to top mount, vf34 and its tonnes better, but I like cornering and not needing 50kms in 2nd to get boost... ya loose a lil top end but car is much nicer and alot more fun to drive... if your going to change it all ide suggest twin scroll...
