I guess what I'm trying to say... imho the most important part is tunability
so if you want to bring it down to the core... for me ... it's the cam gear + the map ecu2 + the colder plugs ... around that if you want to save cash go with a 3sgte manifold, CT26 based upgraded turbo (but not a stock CT26 they are crap, at least get a CT20B), 3sgte dp ...etc you can skip the gauges , but definately get it put on a dyno for tuning... you can skip the MBC ... i don't think the 5sfte is a type of car you'd want to overboost, underboost...etc it just doesn't have the bottom end for you to want to switch between 10psi and 25psi ... so just set it at the right boost (the one you dyno tuned at) and forget it ... that kind of stuff... Tuning is key... The oversized valves are worth 1.7psi A ported throttle body is worth 1.0 psi Cams are worth 2.0psi roughly so having all those and being at 12psi is like a stock 5sfe running at 16.7psi ... see what i'm saying ... -------------------- 2005 MB C200 Kompressor- K&N, Apexi WS2 Catback, DIY Voltage stabilizer, Intrax Springs, H&R RR swaybar, VDO Boost Gauge @ 6psi, Greddy L7 plugs, +0 Rear tires
To Do: E-manage Ultimate tuned up to 12psi |
