1994 miata for the win

 

Nice to see these back on the market. Now to decide this or K swap.

 

Thats a tough call if you are mechanically adept and do not require CARB compliance. K swap costs more but can make about the same power.

Viewed as a $/whp question, the Rotrex comes out slightly ahead. Ease of install is no contest, in favor of Rotrex. Torque, I think a K24 can make 230lbs on gas which is about what we made on E85.

Then there is the possibility of bolting a C30-94 onto a K24. We're already looking at that as a future project. Maybe 400whp and 300lbs tq.

 

Yeah well I bought the whole car for $650

 

Are there any plans to release a C30-94 kit? With wastegate control that would really have a broad torque curve. Wide open it would be a monster.

 

No CARB version but the C30-94 bolts right up otherwise. It will be a simple drop down menu option on the race kits.

 

Just don't tell them that you already have a 1.8 swapped car, and you're planning to swap back to 1.6.

I bet even Emilio will give you a hard time about that lol, just like I do every time we talk.

Heck, Scott will probably ban you if he finds out

(PS: don't do it.)

 

Really going to need a transmission solution at that point. Any plans beside the race only incremental upgrade of gears?

 

We don't, no. We won't be pursuing a solution for the handful of Miata owners looking for 300lb capacity while retaining street manners for under $4k. There are more owners willing to run dogs and the K swap crew will add to that.

Agreed that the community could use a 300lb syncro box, it just won't be us doing it.

 

YES that is something we will eventually be test fitting too. You can make 400whp out of a $400 junkyard Accord motor with a lame header.

 

I'd rather spend time, money, and energy going to the track than having to mess around with too many emissions things.

Besides at least I'm planning on boosting the 1.6 where as i'd likely leave the 1.8 NA if I keep it.

 

Weight also should be a factor. Superchargers aren't light, while the K swap removes something like 60lbs. Probably a 100lb difference over the front end between the two kits.

 

Bro, do you even Rotrex? Shipping weight on my entire C30-74 kit was 39lbs

 

With A/C and P/S removal and the K24 swap, our car dropped over 100 lbs. Its a 2000 and last weigh in was 2278 lbs. Full interior, roll bar, OEM hard top and soft top, race seats and harnesses, no spare tire, and half a tank. Can't complain about that.

That being said, if you are adding weight, I like the idea of adding it in the form of a Rotrex

 

Please stop making this so damned tempting.

Next you'll tell me the Rotrex kit not only comes with a CARB EO but will spontaneously generate kittens as well.

 

Not disagreeing that a rotrex isn't worthy weight to add, and I didn't know that rotrex's were so light. The Lysolm 1.2L twin screw on my car weighs ~38lbs by itself and that isn't even including the intercooler, piping, etc. All together my supercharger kit is probably close to or more than 60lbs. Still worth it though

 

No kittens. Just sparkly rainbow baby-unicorn-shaped bubbles out the tailpipe.

I like my Rotrex. It allows me to drive like a hooligan during autocross, and get more seat time on the edge of traction. Occasionally seat time watching the edge of traction part ways with me.
