Marv and Steve,
The 20B injectors are pretty much the same as the 13B in all the later models. Check the www.SDSEFI.com site, as Ross the propriotor has either made or is representing a aluminum body piece that will hold the injector. Most of the injectors are 10mm IIRC. The body of the injector has an o-ring on it to seal in the bore, and there is a groove on mine that are held in by a fork that is held down by a 6 x 1.0 screw. The 20B has large ports like the rare 13B Cosmo engine and there is a primary injector in the larger of the 2 ports, on mine at least.

 I am making my own intake, and is there any thing it will need (like air hole

 I am using the stock  th/body ?
 will the inj. have the seals on them or do I need them  ? (drill to fit)?
