Sub zero washer fluid tank modified to hold OMP injection oil.

Got the last RA OMP adapter and I modified the factory sub zero fuild tank.

Staring point

Major rust issues



Cut one way check valve up to make a mold to cast my oil inspection window

After casting

Side view

OMP aviation Adapter.

Looks good imo

Yea some one will have problems with my choice of oil but that’s ok.

I had a chance to put 10 miles on the new rx8 engine. Man that thing is awesome, I’m only running the two center ports on the engine due to the nature of the build. But I have to say to anyone wanting to do this swap, that I drive around on two ports and it’s just as fast as the GSL-se engine.

Congrats on getting some miles on your new engine!!

Makes sense that the Renesis would make about the same power as your GSL-SE (1308cc + 2 injectors). You may find that your Reni makes a wee bit more power with higher compression rotors and a larger exhaust port area (combined).

The power on the center ports starts to top out at 5500 or so RPM it still pulls tell 6500 but much slower. I’m actually glad the 3rd and 4th ports are not working quite yet. There is so much work to do and if I was to give it 4ports and the dynamic tuning then I most likely will break a drive shaft joint or something else old from 1985. Also my tires are dry rotted and if I had full power I would be all over the road with burning out.

I’m most excited about the lack of valve overlap and higher thermal efficiency!

Best part is port timing and lack of overlap:-)
