Hi guys,

I have been looking round for ideas on forced induction for my 1.6 miata for a while now and these forums have been a great help. I have noticed a few ppl on here are running a jackson racing kit which has then been upgraded with Emanage, intercooler, WI and so on.
I like the idea of a supercharger kit myself and seeings as the Jackson Racing base price is quite cheap was considering doing a similar thing. Is this a good kit to start with? I have heard it is not a very well designed kit in comparison to others but the roots charger appeals to me.
What I would like to know is how this kit responds to upgrading and how ppl have gone about increasing boost and so on while maintaining a reliable car, as I have read that roots chargers don't like to run very high boost. The power goal for me is no more than 200whp and anything over 150 would be just peachy.
Is this a stupid idea or not? Many kits are available for the 1.8 with better superchargers, are these kits easily modified to fit the 1.6? I have access to fabrication equipment myself if mods were needed, provided they arent too excessive.

Sorry this has turned into a bit of an essay lol, im just a noob.

Cheers,
Brendan

nope, the JRSC sucks. look into a begi turbo kit, or think about DIY. If you're stuck on a supercharger, Fast forward makes a good one apparently.

funny this should come up today. I randomly met a fellow miata owner today who had a jackson racing supercharger on his car today as i was walking up to my miata to head home. He stopped and we chatted and then he offered to take me for a quick spin. My impression was that it was quick, but not quite as much as I expected that it would be. The only place where the supercharger would be making more power is under 2500 rpm compared to my turbo setup (which is currently not installed). Maybe the reason it didnt feel quite as quick is that Ive driven my miata at 10 psi with the turbo and that was very quick compared. Personally I prefer the feel of a turbo and the quiet exhaust of a turbo car.

Ok thanks very much for the info guys, I will steer clear of the jackson racing kit. I would like a turbo from the noise perspective but I don't think I could afford a Begi kit once I get it to Aus where I am, and so will search elsewhere.

Thanks for the headsup on the fastforward place, they look like good kits. Does anyone know about the adaptability of 1.8 kits to 1.6 cars?

for your power goal, you might want to look into the greddy kit maybe, they are for sale on here every once in a while for fairly cheap. new they are $1200 or something. If you are feeling adventurous, you could put your own turbo kit together which really isnt that complex, but many things seem simple once understood. You even mentioned that you have access to fabrication equipment and could save a lot by fabricating a turbo manifold, downpipe, and intercooler piping

Unfortunately, for the 1.6, there is not a lot of choice at the moment for SCs. You are pretty much limited to the JR kit, unless the fastforward kit is finally out. However, last I remember is was still in design vase.

That said, I know of a few 1.6 cars, that did 1.8 transplants, and running MP62s.... That is always a possibility if you want to go SC.... If you were you can get a coldside FF kit, hotside from BRP, and they might have another hotside kit from FF these days....

Basically, if you want to keep the 1.6, it's probably easier to go with a snail.... but the choice is up to you.

I don't think we will ever see anything other than the M45 S/C for the 1.6, and very unlikely that we'll see a coldside anything. If it was going to happen it would have happened. Dave is correct, the easiest way to get more S/C options would be to do a 1.8 engine swap.

I wanted a S/C, the power delivery is better for autocross and as good as a turbo sounds there is nothing like the scream of a S/C. I couldn't go with the M45, it was too limited and really had little room to grow. Once I realized that no one was going to come to market with an M62 or the Whipple I started making plans for a turbo.

Honestly now that I have a turbo I love it. The power delivery isn't that bad for autocross (how often do you drive the car under 4Krpm?) and the kick in the *** as the rush of mid-range torque comes on is a hoot! Took owning a turbo to really understand that a turbo makes gobs of torque, I always thought the S/C was superior in that way.

When I bought my miata (93 1.6) it had the JRSC on it. It now has a greddy kit.

I wouldn't say the JRSC sucks...but I wouldn't praise it. With better engine management, WI, boost upgrade and what not, they are pretty quick. Only problem is all that in a turbo is much faster.

The sc did scream, and looked pretty neat under the hood. If you can find one for cheap it may be worth your while. But in the end, I love my turbo much more.

Brendo

Thanks everyone for your replies, i can see now the JRSC isnt worth the time of the day. I have been in contact with Tom at Fastforward and he is working on an mp62 hotside sc kit atm for the 1.6 and is set for release in the next month or two.
Sounds here like most ppl prefer the turbo kits however and there must be a reason for that, so i'll have another think about it and quiz you guys on anything else I come across.

Thanks very much again for your input, much appreciated,

Brendan

Just another question quickly,

If i were to go turbo and use the Emanage, would I be right in assuming that on these forums there are maps to suit just about any setup? becuase I have no idea how to go about mapping and all that stuff.

I wouldn't hold my breath on the supercharger for the 1.6. BRP was going to do it. Then FM. I think BEGI said at one point it was going to happen. Now FFS? Uh huh.

So far no one has delivered.

The M45 in the Jackson Racing kit doesn't suck, per se, as long as you don't expect to get more than about 175rwhp out of it...or you can double the amount of money you put into it to get to that point and get...drum rollllllllllll...200rwhp, maybe. If God himself was tuning it. And it ran on gasoline formulated by magic pixies. And this were an alternate universe in which tiny, positive-displacement superchargers were able to make more power than intended. And Jesus was riding shotgun on the dyno...while Mohammed looked on with approval.

If you buy a used kit, you could probably use it for a few miles and sell it for close to the same when your tired of it and want more power.

I think an SC would be fun set up, even at only the less of 175rwhp..

FFS is currently beta testing a MP62 Coldside on a 1.6 as we speak. The test monkey is Elphaba in Phoenix.

If it wasn't for the problems Elphaba has had with his stock components, I think it'd be well in the testing stages by now.

As for getting 200HP out of a M45, I hope you mean at the flywheel, cuz you'd be spending a ton of money trying to get it to that HP level.

bripab007

200rwhp has been done, but it required using BRP's old cold-side intake manifold/setup.

Yes, realistically, most people will see in the 135-155rwhp range.

bripab007

I mean, look at BMW and the previous Mini Cooper S. It started at 163hp at the crank, and I believe they were able to get ~200-205hp out of it by the end of that model's run. So, in an OEM app., they only felt comfortable eeking out ~175whp...which means they were asking even less of the little M45 than folks making 175rwhp on the Miata, as we have more drivetrain losses.

the greddy kit is the same price as a used JRSC. Spend $200 on an ebay intercooler and you're making more power.

I enjoy driving my '91 with a 6PSI JRSC more than I enjoy my '91 with 210 HP (1900 pounds). It just FEELS better. Must be kind of like those guys with IRTB's. They have less power than a turbo but they say the ride is better.

needynoob

Another noob here and Im having the same problem,(except I have a 1.8) I have been reading the forums now everday for a month and dont know what to do, I plan on doing some auto X and I figured a sc would be better for that also. I also thought it would be easier to install and w/out as many complications... Still I love the way a turbo sounds and it seems easier to upgrade parts for if I want to spend some more cash.
Guys if you wanted to put $3000 in your miata for power what would you buy? Say we went turbo what is the best bang for the $ and reliable for that price range? Help need more power asap...

blown cars are typically more fun because they feel faster. They make more boost as rpm climbs, so you feel more pull all the way up. Its not linear though like most well tuned turbo cars. It may feel faster, but its not.
