Welcome to BoostedK20! Nice parts list, I would definitely take the "?" away from motor mounts and clutch as you'll definitely be needing both. Stock clutch holds for a bit depending on mileage, but I'd buy your clutch ahead of time just so you have it when your stock clutch goes. CC stage 4, FX300, and FX400 are the most popular clutches being run on 300whp-500whp setups. If you have any questions, don't hesitate to ask us! Can't wait for pics!
