TD04 is a very good setup, tried and tested! quick spool but offering more power and torque then the stock ct9 blower... ontop of that you can run them on 1bar on the stock engine safely, then if and when you forge the engine you can ramp the boost up to 1.6bar and get 250-270bhp... ontop of all that, cheap units to buy and alot of the time stock rad friendly! Race-Tech's kit is awesome... it comes with everything you need to fit one up! http://www.race-tech.net/index.php?main_pa...amp;cPath=2_4_5 Wepr & Zisco also offer similar kits!
