Found a tempting deal for a JR S/C
A friend of mine sold his 1990 miata with a 1994 engine (1.8L), took his supercharger off (buyer wanted it stock) and bought a 240sx for drifting. It was pushing close to 200 hp (supposedly).
He wants to sell it to me for 700.
He had less than 1000 miles on the setup.
I'm only trying to get 150ish rwhp out of the setup.
It includes:
Jackson Racing twin screw M45 Supercharger with less than 100miles on it
Cross over pipe
Water to air cooler
All brackets needed
Boost timing control
Boost time adjustment ****
VAC solenoid
Misc emission electronic wiring box thingy (powercard?)
Air filter
Extra throttle that was used as a dummy throttle
Throttle to filter plastic pie piece
Extra CaS x2
Extra PS pump
That being said some questions I have
Anyone familiar with the Jackson SC?
What are some common problems with the install so I can keep and eye out for bad parts.
Anything extra to adapt it to an 1.8 2002 engine?
I'm searching right now for my own answers, but the deal will be gone on friday so I'm trying to find some help.
Update:
It was a 1994 motor in a 1990 shell.

My 172whp N/A Engine. Stock bottom end. No Porting. - MX-5 Miata Forum
Do that if you only want 150rwhp.

I'm not looking for build advice, I am looking for answers to questions in the original post.

I disagree a bit with the advice you're getting.
Yes, if all you want is a nice bump in power, and you have a cheap M45 kit available to you, then sure, go for it. Worst case scenario, you can resell it and probably not lose any money on it.
That said, if it's not a ready-to-go bolt-on solution, just move on. Don't spend time or money trying to get a seriously compromised setup to work for you -- it's wasted effort that could be put toward a better solution.
So, it depends on your goals and it depends on how bolt-on the system is. Do some research over at m.net, I'm sure someone has (or has attempted) to reuse a 90-93 M45 setup on a 1.8l car. You can get an idea of what you'd be in for.

M45 is not a twin screw supercharger. It is a Roots supercharger.

Only had it for 1000 miles.
That should be a BIIIIGGGGG clue!
The former owner of my red car blew two engines with this exact setup.
Another friend of mine, a very experienced racer, just blew his motor within 59 miles of having TDR (a respected shop) install this exact setup.
Seriously, let Friday come and go and don't give it a second thought.
If your goal is really 150RWHP, check out Emilio's 95R build thread. Nothing exotic there -- just a good, solid build that yields an uber-reliable track car.

You can try calling Moss and asking them what the differences are in mounting a M45 between the years. They may even still have some of what you would need available. Having said that, as someone who bought a Miata with an original JRSC installed I was happy at first but then I wanted more. If you were getting a setup that bolted right up I'd say go for it, but since it isn't it will probably end up costing you more than you think. I would wait for either a MP62 if you want a super, or get a turbo.

The mechanical stuff should all work in that case, but the power card will not work on the 99+ engines because they dont use the optical cam sensor.
You shouldnt use the powercard anyway, it will make the whole setup even worse.

Good call on the MS.
Other issue with a SC is the additional load put on the crank gear and Woodruff key. If good torque is maintained on the crankshaft bolt, everything should be OK. But those bolts tend to loosen (use loktite), and with HP going through that connection to drive a SC, the problem is even worse. We had one member here who literally ended up shearing the Woodruff key when his bolt loosened a bit.
When my friend had his installed by TDR, TDR drilled the face of the crankshaft and the crank gear. They then installed pins into these holes to supplement the Woodruff key. Good insurance. TDR installs a lot of these.
I'd still pass on the SC, but you seem determined to get it. The MS3 is a good thing to get no matter what option you want to pursue.

I understand you all have a lot of expertise in FI, from what I've researched a m45 will give me more heat, a little more power, and about the same fuel economy. I'm not looking to make crazy power out of it (read: 150 rwhp, 125tq).
There is always going to be a better way to get the power I want, and I'll find those down the road and maybe in a different car after I wrapped this one around a tree, or in a rebuild thread later on.
Regardless I appreciate the info!
