drunkenmaster Posted September 24, 2002 Share Posted September 24, 2002 Hi guys, I cant get the search to work so i will have to ask first hand. Which L6 uses a single large throttle body inlet manifold? I want one for an L28 but I as far as i know they come with the twin throttle setup?

RB30-ZED Posted September 24, 2002 Share Posted September 24, 2002 Have a look in my home page link, in the old zed folder is a L28 manifold. I welded a Holden Commodore flange on and ran a 60mm V6 throttle body, very cheap and easy. Steven Quote Link to comment Share on other sites More sharing options...
Tony240ZT Posted September 25, 2002 Share Posted September 25, 2002 http://www.zhome.com/~aktar/zcar/engine/mtb.html Mercedes EFI V8 65mm throttle body, not too hard to bolt on. Little difficult to find though. Quote Link to comment Share on other sites More sharing options...
drunkenmaster Posted September 25, 2002 Author Share Posted September 25, 2002 Thanks guys so far. As far as i know most L28E's in australia have a strange twin throttle setup, one larger and one smaller to prevent reverse flow or something strange? Thats exactly what i want to do. Find a single throttle plenum and weld a plate on to accept a nice big single XF or commodore throttle. Simon from Zbuild.net told me he found his nice big single throttle manifold at a wreckers and it is of unknown origin. I havent seen the OEM twin throttle body in the flesh, as all the L28's have been running carby's that i have looked at. Quote Link to comment Share on other sites More sharing options...
RB30-ZED Posted September 26, 2002 Share Posted September 26, 2002 It looks like Simon is using the Ford 65mm throttle body and like the Holden Commodore which comes in 60 and 65mm clockwise and anti-clockwise, is a dime a dozen, thankfully. Its mainly up to the idle control and throttle position switch you wish to run. Holden use a idle stepper motor and Ford use a duty cycle system.
