Just finished installing my TDR 30-94 kit.
Just finished a month-long install. TDR kit with Rotrex 30-94 unit and TDR PnP Fuel/Timing cards. RoadsterSport header and muffler. Flyin Miata stage 2 suspension with Koni shocks. Flyin Miata bronze Kogeki wheels, Toyo Proxes.

In for dyno results...
Everytime I think I've absolutely, definitely decided against a Rotrex someone posts a Rotrex thread... |

Which kit did you go with or did you piece it together?

I really wanted to go with TrackDog kit, but customs, freight and exchange rates meant it was $2000 dearer than sourcing from local Rotrex dealer here in Australia ..:sad2:
So I went with Bullet Cars DIY Rotrex kit. Essentially the rotrex C30-84 unit, mounting brackets, pulleys, belt, and oiling kit. Just had to provide my own Intercooler and piping. . |
It took about six weeks, 300 miles, and 3 trashed belts to discover there was an alignment issue. About a mm, but man did that mm cause trouble. Loosened and re-tightened the bracket and then checked measurements and it all looked good. Put a belt on it and finally... It drives like it was supposed to. Sorting it out has been a somewhat arduous process, but I’m cautiously optimistic its about there.

That's good to hear! I've been enjoying my recently installed TDR kit on my 1.6 car. We decided on MS3Pro and a full flex fuel set up and that resulted in 262whp and 225wtq (full E85) on Trackstar's dyno in the DFW area. It completely transformed the car. Hopefully you get all the little bugs worked out. 3 trashed belts in 300 miles terrifies me but so far I've driven almost 1,000 miles with only minor "belt dusting."
Good luck! |

Good luck! The car runs fine but throws a CEL for rich running, detected at the upstream O2 sensor, if you’ve been putting around in traffic with stop and go. I’m on the third O2 sensor, this time an NGK unit. Im getting to the point of just ignoring the light. The car seems to run just fine. Im a perfectionist, so “looking the other way” is difficult, but deleting the code and then holding my breath waiting for the light to come back is its own unique kind of hell. |

Was there any spacers reqd to fix or loosening/tightening alone sorted the issue?. |

So alignment of the belts was out, just by having the brackets not tightened correctly?

Correct. And no spacers were necessary in my case. The instructions had to be followed very carefully and weren’t the greatest from a composition standpoint, but re-doing that part of the assembly process sorted the belt-throwing issue.

Care to elaborate what you did that got it to work? The instructions were a bit lack luster in that regard.

I plan to move to E85 with my 1.6. Did you have to change anything in the fuel system? I was worried the old lines might not handle the E85

How's this car running?

Because of the larger injectors and fuel pump, coupled with the fuel/timing cards, a check engine light for upstream O2 sensor was omnipresent. Its been handled. Ill be replacing the belt in the Spring as this one is squeaky on startup. |
You have got to get this thing on a standalone. Fuel/timing cards are letting down the rest of your kit. I made 230WHP on a 1.6 with a c30-74 on pump gas and a street tune. I now have a 1.8 and I'm drooling over the prospect of a c30-94

fair. You should be able to find one for 700-800 but the tune is another story
