Sounds like a very interesting project for sure!! Are these the fishnet recaros like you find in some EP82 GT's, if so they are very cool!! If not, recaros are still cool One concern is the turbo. You often see this turbo used on 1800/2000cc engines, do you think the 1333cc will provide enough flow to get the best efficiency from the turbo? Have you plotted any data on a compressor map for the GT28R? And don't worry about your english, it's fine (better than the text speak that some people use on forums) Adrian
