Product Description
ETi RX-7 13B Turbo Manifold
Product Description
The ETi 13B Turbo Manifold — race-proven rotary turbo manifold built in-house for the 13B-REW. Optimized runner geometry, full TIG-weld construction, back-purged welds, and the flange and wastegate combinations that actually match the turbos serious rotary builders are running. Stainless Steel, Steam Pipe, or Titanium top spec.
Key Features
- Optimized runner geometry — built for high exhaust velocity, fast spool, and instant throttle response on the 13B.
- Full TIG weld construction, back-purged — crack resistance and smooth internal flow.
- Supports 700+whp — built for high-boost rotary applications.
- Five turbo flange options — T3, T4, Twin Scroll T3, Twin Scroll T4, V-Band.
- Four wastegate port sizes — 44mm, 45mm, 50mm, 60mm. Standard flange compatible with Turbosmart HyperGate and most major external wastegates.
- Three material options — 304 Stainless Steel (cost-effective, durable), Steam Pipe (heavy-duty heat tolerance), Titanium (ultra-lightweight, 1000°C+ heat resistance, motorsport finish).
The factory 13B exhaust manifold is a bottleneck for any boost target above factory spec. Generic eBay manifolds run sloppy weld quality, wrong flange spec, and aren't sized for the turbos serious rotary builders run. Our manifold is built in-house with verified flange and runner geometry, properly back-purged welds, and the material options that match the use case.
Fitment
- Mazda 13B-REW / 13B-T
- 1992-2002 Mazda RX-7 (FD3S) — direct fit
- 1986-1991 Mazda RX-7 (FC3S) — verify clearance
- Custom 13B swaps — fits standard bell housing spec
- Compatible with Turbosmart external wastegates (44mm, 45mm, 50mm, 60mm)
Production Lead Time
- Built to order — typical lead time 6–8 weeks
- Crated and freight-insured worldwide via DHL or FedEx
