Re: Dave, while we're on the subject, do you have any Posted by 900 Aero [Email] ![]() ![]() In Reply to: Dave, while we're on the subject, do you have any, Lawrence, Sat, 15 Mar 2003 08:45:58 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Lawrence, the 2.3 '91-'early '93 9000S and T are the same head as the '91-'93 2.1 900 n/a as well as the cams however you may need to mill the drive notch in the back of the exhaust cam for your SPG. Take a look, I built a jig to do this in our BridgePort mill so it's pretty easy! According to Gary Moore's friend Jorgen in Sweden these 2.1 / n/a 2.3 cams are a good way to go. We used them in Gary's trick engine so you can confirm it with him. Jorgen sent Gary a set of 2.3 n/a cams to use but they were '93 1/2 up and the cam to crank timing turned out to be 10 degrees off so I used some 2.1 cams that I had instead. You can also take advantage of the tiny bit of play in the drive notch to the sprockets to widen up the lobe separation some, I have all that documented (which direction on each cam to go) if and when you need that info! Dave
