Jackson Racing Supercharger
Jackson Racing Supercharger
I was looking a a friends supercharged Miata a couple days ago and noticed that it looks like its possible to use the Jackson Racing Supercharger on our 1.6L DOHC motors since its basically the same thing right? All I can see that would be really different is where you route the intake pipe but that could be easily made cheaply. Maybe I am wrong but I think that this would be a possible alternative to turbo.

Also notice that the JRSCs are mounted on the opposite side of the engine from the MX-3s to the Miatas, so it wont work. Already called Jackson like 3 years ago, and no-go.

Re: Jackson Racing Supercharger
ok i think you are wrong in some sense. Take the Miata engine and rotate it 90 degrees to the left and thats how the MX-3 DOHC engine sits. I know that the TB is on the opposite side but you could adapt it to go the other way around if you tried. I really think that it may work since they are kinda laid out the same.

Re: Jackson Racing Supercharger
its true, the intake manifold and exhaust manifold gaskets match up perfectly. I have access to a ton of miata and mx3 parts if anyone is interested in any more interchangeability concerns. this may however be a time consuming upgrade. all piping will have to be fabricated and it is not easy to get near-perfect results. not to mention the way the sc pulley is driven may be a concern. also there is less space in the front of an mx3 than on the side of the miata in terms of mounting the sc in the front over the exhaust manifold---i would look for hood clearance problems first.<p>[ December 13, 2001: Message edited by: boostedmx ]

Re: Jackson Racing Supercharger
Is it just me, or does the Miata version of the JRSC actually look like its almost universal? I mean if you had a cleaver way of mounting it to the engine then you could have a custom length belt made and the piping actually wouldnt be that hard at all. I dont know but correct me if I am wrong. But I still think that it could be adapted to the MX-3 with a little fabrication which wouldnt be all that hard.

Re: Jackson Racing Supercharger
If you look at the miata engine and our engine the manifolds are on the opposite sides. Even if you did bolt it on the pulley would hit the strut tower.. I called jackson also and it is a no go..

Re: Jackson Racing Supercharger
the jrsc is mounted directly above the exhaust manifold, which would be no where near strut towers? hood clearance is an issue because it sits at the same height as the motor but farther forward. the exhaust manifold is on the right side of the engine on the miata and on the front of the mx3. with the timing cover facing the pass side of the car im sure u get the picture. I have had both the miata and mx3 engines apart and the only conflicting differences r the cams and some differently shaped coolant passages in the cyl. head. other than that the manifolds are completely different but use the same gaskets to seal. in the end all i see are a few problems that r easily fixable and the only reason i feel jr is saying that it is a "no go" would be because it is not a bolt up system and there are some things that aren't perfect. other than that the sc does look almost universal in a way that it could be modified to fit almost anything with a little work.

Re: Jackson Racing Supercharger
Thank you for seeing my point. At least somebody sees what I am talking about. So you would maybe have to make a custom hood with a bulge or scoop or something to make up for the hood clearences but I do think it will work with some ingenuity.

Re: Jackson Racing Supercharger
Sure a lot less work to turbocharge the RS. Even if you didn't want to swap a B6T in, you could buy a new manifold from Larsen or CRD, bolt on a turbo of choice, fabricate the i/c pipes and your almost there. Much greater power options too.

Re: Jackson Racing Supercharger
That is true, I can see in your case the benefits of a blower for autocrossing. The only downfall that I can really see for the performance/drag guy is that it is quite limited on power output. <P>You could always take out a mortgage on the house and use a JR supercharger along with a custom turbo setup. Check out the twin charged '85 MR2 in SCC this month.

Re: Jackson Racing Supercharger
also, from the drag/performace side, efficiency is of utmost importance. and a turbo is more efficient than a s/c. the s/c creates a higher temp intake charge than the turbo...and heat is bad
