Some cars need them done, others have done it easily without.

straughsberry Donating Members 1,846 Member For: 17y 9m 7d Gender: Male Location: Broady, Melbourne Posted 15/05/08 04:57 AM Share Posted 15/05/08 04:57 AM So I'll need to do the valve springs pretty early?Stock zorst has a fair bit of back pressure that puts pressure on the valves and hence valve springs, so yes. 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.

Locky28 Member 59 Member For: 17y 6m Gender: Male Location: Rockhampton Posted 15/05/08 07:39 AM Author Share Posted 15/05/08 07:39 AM Thanks for all the advice guys, I think I'll leave out the springs and cat but keep the funds aside as ms said, and dirty excuse my ignorance and slackness to search the forums but what is a UBP and what does it do?Wow if I have to replace so much just to get to 270 I spose I might as well go 300 or so.And sorry if the thread seems like a repeat of that one you linked hanra, but I heard there were some differences between BA-BF regarding springs, cat and so on so I wanted to make sure .

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 https://www.fordxr6turbo.com/forum/topic/45541-looking-at-270-280rwkw/page/2/#findComment-676553 Share on other sites More sharing options...
EZ2CME Formerly XR6NA Member 3,512 Member For: 19y 5m 25d 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.
