Some cars need them done, others have done it easily without. Link to comment Share on other sites More sharing options...

But probably not if you have a free flowing zorst.Don't waste your money on a Monza cooler. As others suggest, bsave your money for something better. Nizpro, Process West or Rapid Systems are excellent choices. Link to comment Share on other sites More sharing options...

Its a fairly restrictive piece of pipe work leading from the outlet of your I/C to the throttle body. http://www.fordxr6turbo.com/forum/index.ph...;hl=restriction Link to comment Share on other sites More sharing options...
EZ2CME Formerly XR6NA Member 3,512 Member For: 19y 1d Gender: Male Location: Brisbane Posted 15/05/08 08:56 AM Share Posted 15/05/08 08:56 AM Im pretty sure that EZ2CME is running 310+ rwkw with a stock cat from memory Pat.But others have also had problems with the cat from 270 onwards so its touch and go...Locky - as mentioned, if your budget can stretch to include a cat it will just help the engine breath a little better so...302rwkw to be exact. That'll be changing when I can save up some dosh again though. Link to comment Share on other sites More sharing options...
