This list is what we call “typical” parts needed to install a 48IDA Weber on a Rotary engine. Pick your manifold, choke size, emulsion tubes, jets, etc. — each part is as an “active” link you can click on – goes direct to the part (except the JEGS links at the bottom)- that you can then add to your cart. The linkage pieces are ONLY for the manifold orientation with the “closer” pair of base bolts/studs TOWARD the engine.

We also like to keep it simple by using a distributor from an 81-85 RX7 (we usually have used ones available — call us), MSD6AL’s from Jegs (need 2) and MSD coils (2) also from Jegs.

When timing a Rotary you NEED a timing light that has a “Rotary” or 2-Stroke switch!! We prefer one we buy from EBAY. Do a search on our website for ES-125.

We have MANY other Weber parts all listed at Mazdatrix Weber Parts

NONE come with intake manifold gasket.
* These do not have a hole for the brake servo vacuum outlet – you need to drill and tap for a fitting.
