An NA Miata with a little extra oomph? How about this ’94 Miata fitted with a Jackson Racing supercharger?

Other modifications fitted include Eibach springs, KYB shocks, an ACT clutch and an unnamed aftermarket exhaust.

Also included in the sale is an owner’s manual and window sticker.

Find this 1994 Mazda Miata available from Cars & Bids.

Wow, a period piece, down to the Rota wheels.

It's already at $16000, wild.

That's very clean, but I have a '96 that makes more power I'd let go for less than that.

yeah 16K is crazy price for an M45 Miata even if it's clean. I wonder if he swapped an LSD in it as it wouldn't be in there stock.

I look at some of those period parts and think "we can do so much better now". Like those springs and shocks.

A 1994 A Package would have a torsen LSD from the factory.

There's one person has decided they want this very badly, the next highest bid is a far more expected $7500.

Nice NA! Although there was a time not too long ago where this was a $5000-$7000 car. $16,000 with 3 days left on the clock is nuts.

I put one of those Jackson supercharger kits on my NA for a while.  It did make some power, at least as much as the stock injectors could handle, but it was much better at making heat and noise. Tuning idle with a supercharger is a PITA, and the ECU piggyback with the kit was a joke.  I would imagine it could be made to run pretty well with a Megasquirt or something like it.

You always struggle with idle on a hot side SC like that due to the throttled volume and the drag from the SC. You can get around it with twin throttle bodies (one pre-SC, one in the normal place) but that introduces other problems. The biggest problem the M45 has is that it was sized for 6 psi on a 1.6, and when you try to push it harder it falls off an efficiency cliff.

Fun fact: when doing emissions testing for a CARB EO, you have to do extra idle tests for superchargers due to the drag.

I had one on a CRX Si. Fun times.

I had an M62 on an NB and it was a nice power bump. I just learned to drive around the idle drop issue.

Took another look at the picture- I remembered that the kit didn't even have an ECU piggyback, it had that weird extra fuel pressure regulator.  I vaguely recall plumbing it into a vacuum line in the manifold, and when the SC made boost it would drive the fuel pressure up?  Funny to see stuff like this from the early days of fuel injection.

I stupidly want to find a D16 Jackson Racing Supercharger for my Civic Coupe. Saw one on facebook marketplace for 1k, but it was for an EF D16 and saw there were differences in fittment vs the D16Y motors. It also sold within a week

In reply to aw614 :

The supercharger actually gave the CRX some torque. 

Trying to think when I last saw one IRL....

I was watching that auction and figured that was a fat finger bid, but the bidder doesn't seem to have done anything to correct it.  He did make the comment that he doesn't even know how to drive a manual trans....
