“Rocket Funny” RX7 Thailand
Now that’s a massively reworked engine,
with its three-rotor configuration, bridge
ports, Apex Seal racing engine seals, and a
GTX 42 turbo with boost of 0.9 bar.
To cope with all that power, an ORC clutch, and Cusco limited slip
differential is added to the stock five-speed manual transmission.
One final aspect of this build worth mentioning was that as the engine
was rebuilt, CMZ Rotary Competition replaced the old engine seals with
new Racing Apex ones, and bridge ported the rotary engine. While this
adds power, it is something rarely done for turbocharged rotary engines
due to cost and complexity, so for CMZ Rotary Competition to take on
this job, and pull it off is worth congratulating. H
