Noz Posted October 12, 2012 Share Posted October 12, 2012 Hi all. Have often seen a staggered set up with cams, 256/264 etc, was wondering if a stock cam with a high lift cam would give any benifit. 272 to be exact. And if any benifit, would this just run on the stock gear? Thanks Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted October 12, 2012 Share Posted October 12, 2012 The numbers denote the cam duration not the lift, turbo engines respond quite well to a longer exhaust cam duration, but lift is not really much of an advantage due to the forced induction.

Noz Posted October 12, 2012 Author Share Posted October 12, 2012 I supposed with lift you still have the bottle neck of the port to contend with? I knew the duration was denoted by the number the lift is usually 8-11mm somewhere I think. Im tempted to try and exhaust cam, as my stock intake has a dizzy gear im limited to having both. would I be able to run this on the stock gear?

Your wording here is quite confusing. You say your stock intake has a dizzy gear which isn't correct as the dizzy gear is part of the exhaust cam so I can't seem to understand what your trying to accomplish here.

Noz Posted October 13, 2012 Author Share Posted October 13, 2012 Is it?? I haven't look at cam's for ages mate I completely forgot! It's meant to be worded - Im tempted to try an exhaust cam, not AND exhaust cam. Your right though, the dizzy is on the exhaust side therefore would run off the exhaust cam. So, making a GTE exhaust cam pretty pointless. Thanks mate, put an end to that idea anyway lol. Bloody dizzy Link to comment Share on other sites More sharing options...

Not on an N/A, in any case all aftermarket cams for the will be exact copies, what i don't understand is why the N/A will have longer duration and probably higher lift anyway, as turbo engines don't need the overlap, have you checked what the std cam duration is?

Kirk Posted October 13, 2012 Share Posted October 13, 2012 (edited) I'm also a little mixed up here. What's not on an NA? In any case here is a set of NA cams. 10 points for guessing which is the exhaust side Edited October 13, 2012 by Kirk (see edit history) Link to comment Share on other sites More sharing options...
johnny g Posted October 13, 2012 Share Posted October 13, 2012 The cans are the same aren't they? The bc272 I had we originally for the 2jzge Link to comment Share on other sites More sharing options...
Noz Posted October 13, 2012 Author Share Posted October 13, 2012 GTE cams dont have a gear to run the dizzy off buddy. I thought it was on the intake cam, haven't looked at it for a while and forgot exhaust cam is on the dizzy side. I'd need CoP or hard weld the OEM cams. A right PITA!!!!!! Alot of websites for some reason do list GE cams, I might send an email and enquire as I wouldn't understand why the BC website would list cams if they need a complete different ignition setup.

Kirk Posted October 13, 2012 Share Posted October 13, 2012 Don't forget the GE doesn't have cam or crank sensors so the dizzy is used as the pickup so the gear on the cam is crucial unless you modify the for cam/crank sensors or switch to a halls setup.

Noz Posted October 13, 2012 Author Share Posted October 13, 2012 Halls would be a right pain, I looked into it. Pretty sure you can run ignition off a standalone with crank sensor? I thought.... :O Link to comment Share on other sites More sharing options...
