  • Shouldn't you have some sort of restriction or cover plate over the internal oil pump galley? Seems as though you would loose a ton of oil pressure through this.

  • and i hope you will follow the just natural street racing concept abel has made for his rx8 with a ice tank wich are included both for intake manifold cooler and intercooler,the idea behind is that it lowers the starting temperature wich is actually just brilliant when you want to make a lot of horseswith love Amir,@Rob dahm

  • I gotta give him props - just for being able to mentally endure working on / dragging on a project car for this fuckin long... seriously though a is there a car (or any vehicle with 4 wheels) that’s taken as long as the 4rotor build? There’s gotta be a Guinness world record in there for “longest time spent On a car build on TRvision “

  • great progress :D re sump, if it was me, id be taking the sump off again, not sure why you didnt, id be cnc groove in the sump 3-4mm wide 2-3mm deep groove around the sump where the sealing surfaces are etc, so it seals better, or even get an oring big enough to put in groove, flat surfaces sometimes dont seal properly and leak etc re rear oil pressure regulator, id check with the engine builder first, ask what is needed etc, no point damaging an engine over a cheap simple thing etc also if needed, racing beat sell an adjustable regulator :) zoom zoom zoom

  • Now to avoid failure Pull the sump pan off and remove all the RTV that oozed out into the sump and will clog the oil passages, Never use RTV like that . If you need to use RTV instead of a real gasket lay the bead so that any excess squeezes out to where it will do no harm.

  • The worst part of building an engine is when you need one more item, which you have not laying around and have to order and wait for it!! Looks like you have that in place, and that is so satisfying :) Good luck on the build!

  • You better change your oil filter pretty quickly. All of that heavy gasket maker is going to make it into your engine. Just as you see it outside the block and oil pan,It's tenfold inside the motor. Trust me. You should have purchased some gasket material,then cut out a real gasket. That black RTV is going to cause problems. Probably starting in your oil valve.

  • When he steals parts off other cars you know its the 3 rotor and he really wants to get the 4 finished. ahahaha but all jokes aside i wish you all the best!!!

    Ben CallahanBen Callahan5 aylar önce
  • Just a crazy observation, but since the engine has a completely custom externally supplied oiling system, with if I remember correctly, a direct external oil feed from the dry sump pump to the rotor bearings, wouldn't this mean that the standard oil pressure valve is not used, hence it was not fitted, and the dry sump pump would be regulated to supply correct pressure? Seems to me the opnly standard oiling on that block is the standard drillings to front and rear E shaft bearings? Did the supplier of the engine not give any schematics or instructions for how to setup the lubrication system?
