You Need This: Jackson Racing-supercharged NA Miata

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.
