With an undersized IWG turbo though :p: and it was 2” OD T321 tube, not pipe. So not much bigger than 1.5” pipe on the outside, but more open on the inside.
also 4-port, so no APV assembly etc., I was going to check fitment on my 6-port car soon, maybe this weekend. I did find a source for Sch 5 T321 pipe elbows though and might have gone with 1.5” (1.9” OD) instead. . |

Enjoying this thread ...thanks all.
I am trying to get back into the rx8, but the lack of power ( for me) mandates a plan to accomplish that before I jump. 325 rwhp with a great torque curve and ability to survive a road course is my goal. This thread helps in understanding how to acceive this. Appreciate it. |

You can forget about even wishing about getting a 7670 EFR down in there :lol: holy crap, I gained some respect for that other guy that put a 7063 in there on the 6-port. Wish he hadn’t deleted all his vids. Definitely need a whole different motor mount arrangement, but I was already counting on doing that. It was a lot tighter than I was expecting between the length, compressor cover accessories, and wastegate mounting bracket. A reverse turbine setup would be easier, but no such thing for now. After seeing Elliott post that they were hitting 30 psig by 3000 on an REW and E85 with the 7670 that sounds like a much better option now :rofl: . |
I see ... kinda like bringing a new woman home ...getting her 'in the mood' then ..................."yeah nah , I just wanted to check if your hair matched my new sofa".

I suppose you got me, even if it doesn’t make much sense :scratchhe
Not sure if I’m going to finish rebuilding the one build I have let alone a second one, but that’s life. . |
Was not supposed to be a blow ....just having you on ! As you do me ;) . Didn't know about the reason ...sorry to hear that man !

You got it brother :)

Hey Brettus, I just noticed that you're using a T3 spacer between turbine housing inlet and the turbo manifold. If you're retaining the spacer with the new manifold I recommend you port the mani/spacer/turbine with a die grinder to get a smooth flow between manifold and turbine inlet. I ported a similar spacer on my old Greddy setup and it made a big difference.
What's the time frame for the new manifold? |
I just had that spacer made locally ... didn't have to port it out but I had to port the hell out of the turbine housing !
What new manifold ? |

Don't you just use the whole liter per tankful on that Methanol beast?

I like it. I deleted my omp. Rebuild has never had an omp functional on it. Premix since day one. I'm trying to set up pre measured bottles so it's dump and go at the pump. No more awkward measuring in the trunk before pumping.

Is it worth dumping a bottle of Race gas or is it mostly gimmick.

Don't know much about it ..........but you certainly wont get anything from an octane boost in an N/A car if that is what you were asking?
|
Race gas actually burns slower than regular
That's what octane is all about. Thats why the petrochemical industry makes money... selling higher octane fuel to people because they think its "better" It's only better if you need it... otherwise it is just throwing money down the drain And don't get me started on octane boost products.... 🙄 |

. Came up with these : 1/Everything works 2/Engine is very well behaved ....like a stock N/A engine but with double the power. 3/Fuel consumption and therefore range is stock (out of boost). 4/Renesis is limited to 400whp but ........... that actually is enough (for me anyway) . More and you need to think about replacing the rest of the driveline anyway. 5/EVERYTHING WORKS...PROPERLY! |

Was thinking about this comment and whether there are actually any good reasons to retain a turbo Renesis engine vs a turbo REW in a street driven RX8 chassis.

I was actually referring to the turbo choice, but listed the rest of it to be factual.
But responding back, for a lower hp street car that needs to pass emissions I’d concede that, otherwise even if you aren’t turning the wick up all the way imo an REW with Adaptronic Select is still the way to go otherwise. Somethings function under your scenario, but not all things perfectly as you suggest. You have a lot of kluges and workarounds using a factory non-turbo street system where in the case of the Adaptronic it’s made to incorporate all the turbo stuff seamlessly. Not to say what you have doesn’t work, but look at what all you’ve been through to get there. The Renesis still has a lot of shortcomings as a turbo engine. It’s the better NA choice hands down, but in the same respect the REW is the better hands-down choice for turbo use. Don’t give me that “I don’t need 25 psig boost reliably on street gas” baloney. Just go play with the other girls and their dolls already :rolleyes: :lol: |

Re the turbo ..... I'm actually seriously considering doing another setup (in another car) with an EFR7670 1.05 top mount. |
