Castrol Posted January 12, 2006 Share Posted January 12, 2006 I think the answer to this is a no-brainer but I just wanted to make sure before I go ahead and spend my hard earned at Autosport on Saturday. Zetec 2.0l, currently running standard cams, lightened flywheel and Raceline headers and silencer, Omex ECU. Its 45s for the TBs, right? Thanks, Matt.

Graham Perry Posted January 12, 2006 Share Posted January 12, 2006 Castrol, all the info you need can be found here there is a good piece in the 'advice and FAQ's' section that suggests various sizes depending on expected power per cylinder.

I.Mupferit Posted January 12, 2006 Share Posted January 12, 2006 On my 2L Zetec, Dave Andrews recommended the 45's without question, and it ran superbly so that's what I would go for. Brent 2.3 DURATEC SV Reassuringly Expensive R 417.39 😬 Link to comment Share on other sites More sharing options...
Castrol Posted January 12, 2006 Author Share Posted January 12, 2006 Graham and Brent, Thanks for the feedback. Now the Jenvey site has confused me! From their rough data it would seem that 42mm is the correct one to go for at up to 56bhp per cylinder. Would this also give better drivability over the 45mm due to the slightly increased air flow and better breathing over the 40mm due to the larger size. Sorry if the questions are a bit numpty but I don't want to make the wrong decision! Regards, Matt. Link to comment Share on other sites More sharing options...
I.Mupferit Posted January 13, 2006 Share Posted January 13, 2006 My Zetec was 209 bhp and I asked Dave Andrews exactly the same question as you have asked but he assured me that driveability would not be an issue. I have to say that certainly proved to be the case. Why not give Dave a call if you want further assurance, he is very approachable and free with his advice even if he isn't doing the work for you.

Graham Perry Posted January 13, 2006 Share Posted January 13, 2006 If you think you are going to get a touch of upgradeitis in the future then 45's would perhaps be the best option, but Dave would know Link to comment Share on other sites More sharing options...
