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 > > > > > > > > > > > > > > > > > > > > -----Original Message----- > > > > > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Kristian Walsham > > > > > Sent: Tuesday, 30 July 2002 9:58 AM > > > > > To: [EMAIL PROTECTED] > > > > > Subject: inlet manifold > > > > > > > > > > > > > > > > > > > > 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. > > > > > > > > > > --membersozdat------------------------------------------------------- > > > > > OZDAT Mailing List Please Note:- > > > > > Send (un)subscribe requests to [EMAIL PROTECTED] > > > > > Send submissions to [EMAIL PROTECTED] > > > > > No unauthorised redistribution of this email > > > > > http://www.ozdat.com/ozdatonline/index.htm > > > > > http://www.ozdat.com/ozdatonline/listindex.html > > > > > http://www.mail-archive.com/[email protected]/ > > > > > --------------------------------------------------------------------- > > > > > > > > > > > > > > > --membersozdat------------------------------------------------------- > > > > > OZDAT Mailing List Please Note:- > > > > > Send (un)subscribe requests to [EMAIL PROTECTED] > > > > > Send submissions to [EMAIL PROTECTED] > > > > > No unauthorised redistribution of this email > > > > > http://www.ozdat.com/ozdatonline/index.htm > > > > > http://www.ozdat.com/ozdatonline/listindex.html > > > > > http://www.mail-archive.com/[email protected]/ > > > > > ---------------------------------------------------------------------> > > > > > > > > > > > > > > > --membersozdat------------------------------------------------------- > > > > > OZDAT Mailing List Please Note:- > > > > > Send (un)subscribe requests to [EMAIL PROTECTED] > > > > > Send submissions to [EMAIL PROTECTED] > > > > > No unauthorised redistribution of this email > > > > > http://www.ozdat.com/ozdatonline/index.htm> > > > > > http://www.ozdat.com/ozdatonline/listindex.html > > > > > http://www.mail-archive.com/[email protected]/ > > > > > --------------------------------------------------------------------- > > > > > > > > > > > > > > > > > > > This message was sent through MyMail http://www.mymail.com.au > > > > > > << File: reply >> > > > > > > This message was sent through MyMail http://www.mymail.com.au > > > --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[email protected]/ ---------------------------------------------------------------------
