How come I can run 18-20 degrees of advance without pinging (much)? I have an L20 with S2 dissy and recently have added 32/36DGAV And I only use regular unleaded.

Hey guys
Would one of these webers give better power/economy than a pair of SUs? Running on a L20B?

Just a quick one Terry, is the standard�jetting on the 32/36DGAV on the rich side for the L18SSS considering it came from a two litre Cortina?

Kris,

S1 Bluebird has about the largest runners and base holes of any of the L4 downdraft manis and a S2 Bluey could be the same but I don't know anything much about the technical specs of them. There isn't much to be gained simply by fitting a larger runner manifold unless the head ports are�at least the same size, some A87 heads have 38mm ports.�There are a few holes to weld up if you use a L20B mani as they have EGR etc - not hard to do though.

Usually a 32/36 will run well with 12-14 degrees of initial advance on the Bluey S2�dizzy with vac advance connected�and 96-98 octane so if it's not detonating then it's pretty close to where�the engine likes. Usually going up hill at around 4000 rpm at WOT in 3rd on a 40 degree day will sort it out.

regards
Terry

Hi all,
�������I have a 32/36DGAV on a L16�manifold on my L18SSS engine�and seems too restrictive. I believe there is manifold from an L20B engine that is better suited. The head is an A87 but i don`t know if�it is the larger or smaller port head. ��Can someone tell me which car this manifold�would be from please.
��� Also, i have the elec. dizzy and was wondering if i set the timing at 14 deg BTDC will this provide too much total advance with the vac advance hooked up? The car doesn`t ping though.� I have two timing marks on the front pulley, one lines up with 0TDC and the other lines up with 15Deg BTDC is this the�correct way to set up the timing? I have never seen this before on a factory engine.
��������� I use Caltex Vortex Premium 96 octane.
�Sorry for rambling on.
Much appriecated,��
������������������ Kris.
