Jackson Racing H22 Supercharger Kit

[Tina Larzelere]

Thisreview is of a long-term...vintage....Sebring Supercharger that was originally sold new in 1994. This is a very early unit which came with nobranding cast into the blower outlet. It was one of a few that were sold at very deep discount just to get some visibility. I purchased it in 1999 with 35K miles from the original owner, who lived in Ohio. I posted a review shortly thereafter and 2 updates....so this is my fourth posting about the same blower and the same car! The unit was sent to the Eaton distributor in California for "S" porting and upgrading the front bearing. This unit now has about 200,000 miles on it plus the original 34K and thanks to the "S" porting delivers a consistent 7.5 lbs of boost. The blower has been installed on my 1990 "A" package Miata (build number 3014) for 10 years, with only minor maintenance. At the time I installed it I also installed the upgraded air delivery system which has never, ever leaked since. The original MSD boost timer is still being used. The car also has a 10 year old JR header and Flyin; Miata suspension with Tokico 5-way gas shocks and mild lowering springs. This th!ing just keeps on keepin' on.

My experience has been excellent. This remains the single best performance enhancement I have ever installed on any car. It came with a pretty clunky Bell AFPR which was replaced with great relief with a JR unit, which has worked perfectly for over 5 years. A few years ago I replaced the crude and not all that good belt tensioner with a much more effective JR tensioner. This car has been raced in Solo II for almost 10 years. The original viscous LSD was replaced with a Torsen in 2003. The 1.6L flywheel was replaced with a 1.8L flywheel that was lightened to weigh about 9 lbs and I use an OEM 1.8L clutch. About a year ago the blower started to make a rattling sound which was due to some wear in the snout which was easily repaired with parts from the Eaton distributor. At that time it was disassembled and there was no visible wear inside the blower....not a scratch. I have also made some of my own modifications to make cleaning the air filter much easier. The blower transf!ormed this car. With the lightened flywheel it became a tire smoking little beast and I have to replace the tires every 18 months or so.

My little car just celebrated it's 20th birthday and it's 370 thousandth mile. It remains my daily driver and the best car I have ever owned. It received a new top (it's 3rd) and leather upholstery (second reupholstering) 2 years ago. On July 19th, it's 20th birthday, I picked it up from Prime Collision in Marietta GA where it had been completely taken down to bare metal and received 4 coats of Classic Red paint and 3 coats of clear and polished to perfection. Next week the leather on the steering wheel gets replaced and then we're off for another 300,000 miles or so. On a few rare occasions I have thought about retiring the car from daily use, but it's so much damned fun to drive I don't think I could do without it.

Jackson Racing M45 Supercharger kit, 6psi, for '94-'97s with AC and power steering. Complete kit comes with supercharger, belt, all necessary piping, air filter, JR PowerCard, all necessary hardware right down to wireties.

Excellent! I had my doubts as this kit is the least expensive SC kit that can be bought brand new. Still, it took me a while to pull the trigger as the kit costs almost as much as my car did. I should have done this sooner(well, I know JR has added/improved bits of the kit recently, and I'm glad I bought the latest and greatest from them)! Kit takes 8hrs for a mechanically inclined person, according to JR. Took me about 9 hours, and I'm not an ASE certified Mazda tech or anything, and I had to fix a few parts of my car in the process. Not only were the instructions straight forward, I learned a lot installing the kit myself. The Good:Straight forward to install.Product quality seems to be high.Excellent driveability, both when running WOT trying to get somewhere fast or just cruising around. Every single piece needed to install the kit is included.The Bad:Hot side supercharger gets VERY hot. Intake track doesn't seem to fit properly - the couplers/piping are too short and I had to cut off the screw hole on the air filter assembly to move it a few inches towards the firewall allowing the couplers to fit properly.Throttle Cable mount is improper - I had to flip it around compared to what is shown in the instructions to allow for the proper cable tension, no big deal. The Verdict:This kit is for the DIY Miata-er looking for naturally aspirated reliability/driveability with the increased power of forced induction, all in a realitively easy to install kit.

An intercooler would really help reduce intake air temps, which I plan on installing soon. A few people on the Miata.net forums have experimented with leaving the throttle body on the intake manifold, instead of moving it to the supercharger as JR instructs, with overall good results, but it takes a bit of work. I'd like to see JR create a kit to do this as it has advantages over the current setup. Thanks for reading!

Bought the kit used from a fellow miata.net member, had to go find the JR powercard, Bipes ACU and other items separately. Had local shop install the unit (knowing some pipes, bolts, hoses MAY be missing) Took about 2-3 days to install, no rush had to source extra parts etc. Ordered additional items from Track Dog RAcing: manifold heatshield, insulated intake gasket, idle check valve, colder plugs, wires. Very good power indeed. Had a friend drive my 2000 Accord V6 to drop me off to pick up the '97 miata SC. Haven't had a chance to dyno the setup yet, but my friend and I mashed it every light, stop sign, on long stretches of freeways, uphill. And the miata just pulls away every single gear. The Accord 3.0 v6 is 4-spd AT modified and dynotuned at about 185whp weighing about 3350 lbs.

When my Miata hit 280,000 miles I decided to rebuild the engine and add a Jackson Racing Supercharger. I'm sorry but 98rwhp is not ok in 2006, especially when minivans can out drag me. Reading all other owner installion reviews, I decided to try out the J.R.S.C. I have a 92 Miata with a brand new 1.6 motor. Installation was a full day, do to I also added a JR Header and took my time. Instructions are poor, no good pics and what I though were alot of skipped information, like vaccum lines, Fuel Reg. Lines pics etc. What really made this install a breeze is all the pics and write ups I printed from Miata.net, - Club members. studying thier experiences,Pictures & write ups really help me. I got mind from Moss motors along with a JR Header & MSD Box. Bought it monday morning got it wed. afternoon. Nothing missing all parts complete. Thanks Moss Motors....As for power, it like what other Reviews had said, " Its How the Miata should have came from Mazda." a nice smooth wide band power from 2800rpm - 6000rpms. I love how I can go up thoughs long freeway on ramps and passing other cars, where before minivans were passing me. Using 91 octane, and a MSD timing retard Box I have not had any pinging, just the sound of that SC spinning. To give you a sample of the JRSC acts like, I've challanged my friends Acura RSX with stock 200hp, We ran up a short on ramp at 40MPH then down a straight away all the way to 130MPH (which is my max) and I stayed in front. Noway with a stock Miata. The most important thing to do when you install this JRSC, have it tunned by a high end shop. That will make your JRSC run its best. If you want to go agaist nissan 350z or S2000, Go for! a FM Turbo setup. My friend has a 90 miata with that setup, and he pulls away from me. all in all the JRSC is perfect for my every day driving to work.

A Must is a JR Header with free flow exhaust system, Upgrade your clutch, cause the stock one will not hold, 91 Octane, MSD Box or JR Box (Timing) and make sure your Fuel Pressure is where it should be. Have it tunned while on a Dyno, to get it running perfect. I got 154rwhp with my setup. I plan to upgrade it with an intercooler & a 8psi boost upgrade . With the cost of $2700.00 including the header, a MSD box Colder Spark plugs etc. Its worth it, you won't be sorry, it will make your Miata come alive

This supercharger was purchased from Moss Motors on sale and for the price I feel a good upgrade for the car. This system is exactly what I was looking for. The product was packaged well and complete with the parts separated into individuals packages for easy identification. I found the instructions easy to follow and installation was straight forward but should be installed by someone with mechanical experience. Not all applications are the same and even though the instructions are complete a little ingenuity is required to make things fit perfect. The Power Card fuel management system is very easy to install, so it really boiled down to just hanging hardware.

This FI system is perfect for the street if your looking for more horsepower but not so much were things become difficult to manage. I'd say it's almost bomb proof only because I haven't experienced any problems what-so-ever other than a little continuous observation of the belt and a few adjustments so everything's running correctly. Horsepower is linear, smooth and very managable. The car behaves like stock until you really step into the throttle, then the fun begins. The power range begins in the lower rpm's where you can really use it for the street and pulls nicely all the way up. The stock clutch handles everything just fine, but for me an ACT is scheduled for the future because I track drive the car. After a day of hotlapping on the track the car performed well with absolutely NO problems. A few suggestions: in addition, buy the suggested colder spark plugs, upgrade to a synthetic motoroil, (I'm sold on Mobil-1) and read the instructions two or three times to familiarize yourself with the installation process before you start. This is really a great product for the price and a nice upgrade for someone looking for more streetable horsepower. If your a power hungry enthusiast I would suggest spending more money on one of the other systems that will give you what your looking for.
