This Mazda RX-8 is being built by Race Works PL (formally Hepp Garage) in Limanowa, Poland. The car was previously powered by a twin-charged stroked 2.9 L BMW M50 inline-six featuring a BorgWarner S300SXE turbocharger and Eaton M62 supercharger. They recently swapped to a twin-turbo 5.0 L Mercedes M113 V8 featuring two JRspec GTX3076R turbochargers and a 1 mm decompression plate. The V8 is mated to a ZP six-speed (BMW M57) manual transmission using a Poweride adapter plate, flywheel, and twin-disc clutch.

Neat rig. I wonder how much the merc v8 weighs..
413 lbs with accessories from Pelican Parts forum
168 kg n/a one of the lightest V8 engines and very reliable , plenty of spares and tuning . Easy manual conversion for front engine rwd.
So even after all that work.. it’s STILL unreliable
do you own an rx8 that makes you say that?
Some call it Blasphemy, I call it goals
Naw, I just call it an abomination.
I would of said beautiful.looks stunning and I bet it shifts.

Power output? Dyno numbers? Power gained?
The builder just finished installing the engine. Once they post those numbers, I will update the article.
That would be great
Greetings. Did they ever post the power numbers for this build? Thanks in advance.
Hi Kip. I searched again and could not find any details on power output.
Well, thanks for the quick reply, anyway! Please post if they ever show up. Really curious about this. Thanks again!
How can it be a RX if it ain’t got a rotary engine, I think they haven’t understood what RX stands for.
Somebody wrote a prescription for 8 glorious cylinders to replace the two sad rotors it was born with.
How can a miata be a miata with a 2 rotor wankel in there.
