Sebring Supercharger

Found a nearly complete Sebring Supercharger kit for my 1990 Miata for $750C+S&H. The only thing it doesn't come with is engine management (Hello, MegaSquirt) and a belt. Now, I seem to recall that the Sebring kit eventually became the Jackson Racing kit. What I am wondering is, are service/replacement parts available out there, should I choose to buy it? And is there anything to watch out for on these old kits?

I would suspect the actual supercharger is a Eaton unit. Do you know what make/model?

That would be the easy route imho.

I'm fairly certain that is an Eaton M45. Found an old install manual online.

Yeah, it's an M45. Undersized for anything but the original application, which was 6psi on a 1.6. Intake temps skyrocket it you try to go much further, so resist the temptation to crank the boost.

IIRC, problem areas were idle droop, the idler pulley system and sometimes the blower brackets. Track Dog Racing is the only place that might have anything for it, as it was discontinued years ago. The blower can be rebuilt by Eaton, I think they had a 100k lifespan or so in that application.

Good for around 145 rwhp if memory serves. I had one years ago.

In reply to Keith Tanner:

I figured you would chime in. Yeah, I read people had problems with detonation as well, but I figured here in NY, with it's cooler climate, and 93 octane I should be fine. I've said before that I'm really not chasing maximum power numbers, more just improved area under the curve, which is where a positive-displacement blower is at it's strongest. And for the amount of money he's asking, it seems like a decent return.

I still run one on my 1.6 at 9psi with an old school link ECU.Track only for me and for sure its better than no SC but the sucker makes LOTS of heat.

I was running a W2A i/c and it would just heat soak,I now use a 3 core aluminum civic half rad with side by side RX7 A2A i/c.Miles better,30 hard min on track and you can now hold your hand on the intake tube from the i/c afterwards.

No finger prints left if you tried that with the old setup.

Just out of curiosity, does this exacerbate the crank snout problems already prominent on the 1.6s?

Not really. That remains primarily a loose bolt problem.
