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
| Part | Description | Quantitiy | Details |
|---|---|---|---|
| C-WEBER-48IDA | Carb | 1 | These are the ones WITH the extra “progression” holes |
| Intake Manifold – Choose yours | 16493 – 13B 6-PORT 86-92* 16492 – 84-85 13B 6-PORTS* 16494 – 86-92 Turbo* 16484 – Early 13B 4-PORT 16495 – 93-95 13B Engines* 16482 – 12A | 1 | Some have carb base gaskets, most do not. 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. |
| Fuel Inlet – You Choose | 99301.380 – WEBER INLET FITTING for 8mm (5/16″) push on hose 30606-M12D -AN -6 TO WEBER 12MM (For this fitting you also need: 357-12MM-STAT -Seal | 1 | |
| Whichever Intake Gasket you need | Intake Manifold Gaskets | 1 | |
| Air Filter and Canister | 56-1210 | 1 | Chrome Canister + K&N Filter |
| Throttle Cable | FA01-41-660 | 1 | Actually 81-85 12A – fits carb linkage and about any Rotary car |
| Shaft Lever w/pin stop | MAT460-L | 1 | Special piece we have make for us (thinner to allow more thread on shaft) |
| Shaft Lever for Throttle Cable | 444.614-04 | 1 | Fits the end of the 12A throttle cable and most pedals and firewall hole |
| Base Gasket | 99005.035 | 2 | Check manifold picture to see if it includes the gaskets |
| Stud for carb-to-manifold | AV11981 | 4 | Check manifold picture to see if it includes the studs |
| Intake Manifold to Engine Stud | 250-8-30 | 2 or 6 | Longer Stud needed for Manifold to Engine |
| Manifold Nut | 967-NUT | 4 | We really like these 8×1.25 nuts that use a 10MM wrench – easier to get to them |
| Float Needle and Seat (3.0) | 79504.300 | 1 | Rotary engines need a LOT of gas – this is the largest float needle currently available |
| Choke / Venturi | Pick Your Size | 2 | We list from 36mm to 46mm |
| Main / Fuel Jet | Pick Your Size | 2 | We list from .085 to .240 |

| Emulsion Tube | 61450 | 2 | We generally prefer the F8 — others prefer others |
| Heat Shield | 16219 | 1 | VERY good to have |
| Throttle Cable Stay | 444.00SS | 1 | Makes hooking the cable up MUCH easier |
| Carter Fuel Pump – low pressure – Buy from Jegs | 180-P4600HP |
| Aeromotive low pressure regulator – Buy from Jegs | 027-13205 |
