Look at these lil superchargers ;)

I'm thinking that the C15-60 would be great on the Mazda2, it should work good because of the size of this unit. But making it work and fit....maybe Corksport can make a kit out of these hint hint hint lol

Hey why not use a Mazdaspeed3 top mount intercooler for a cool effect and modding the hood to match the oem Speed3 look lol Nah, too much work, FMIC is the only way to go

I still think that a Supercharger is best for auto-x, the engine feels bigger and has predictable power. Turbo is great, but less predictable than SC... but that my taste.

or go with the C30-74

Rotrex blowers are good, but you need to know how they are. Just like other centrifugal blowers they make more boost the faster it spins. So down low you still aren't going to really have much more torque which is where you really need it on the 2. They do add restrictors on the inlet yo keep the boost level more consistent on the top end which is great, but it doesn't help with the low end.

As an example I helped to put one onto a base 2.4L solstice. It made 350WHP at redline, which was 7000. Max Torque was at around 6500. It just keeps building boost the entire time, very strange feeling to drive as well.

Oh and they are expensive. They work really well on truck engines where they have a ton of torque, but no top end.

I would be lying if I said I wasn't thinking on putting a M45 on my 2 down the road. It will be at least a year before I do. For the placement for both I saw a picture of a supercharger kit for 2 that had it mounted next to the engine, on the front. There is a pretty open spot there for it.

I know Knightsports went with the Rotrex blowers for their SC kits and they work pretty well. I think a huge amount of torque in the 2 gearbox is a bad idea (diff goes boom)

I was think of the same thing about the front spot for the SC. It will be a short run to the intercooler and into the throttle body. Yeah low end torque is important for the 2 but too much isn't good. And Derrick just raised an othe good point the tranny/diff won't like it. I lil bit more is all the 2 needs to perform well and it's not a drag racer's car. Keeping the revs up and going nuts on the road course is what I got in mind.

 

[zps2004]

I agree that things will eventually break, but do we know when things will start to go? I mean a Miata doesn't have much torque from factory, but the tranny and diff handle much more. I would rather know where things break before worrying about it. Also, what breaks and under what circumstances it breaks is important.

With the Chevy Sonic stuff I help out with they have 150ftlbs from factory and we have seen over 240Wtq out of a modified version with no issue.

For me the car will be a DD and autocrosser so I would rather have the power from 2000 and up. I would like to have at least 150Wtq and 150Whp out of it. Mainly because in a FWD car I get annoyed with how patient you have to be with the throttle to avoid wheel spin. I can do it just fine, but I just think about how early I can get on the throttle in my Miata in comparison, let alone when I drive a Evo or STi and it gets annoying having to wait to be able to apply throttle. Damn weight transfer. lol

There's a turbo kit being made for the 2, for what you want it would need a small turbo for fast spooling action.
As for the diff breaking down, we need to find an lsd diff for the 2....

 

[zps2004]

Making the M45 work isn't the hard part ,the only thing I need is the tune which is why I am hoping that Joe gets the remote tune going.

Small turbo would work, but for it to really hit boost well at 2K it would be choking up top some. I am either going to do an NA build, or supercharger and the M45 will be the way I go. The main thing I don't like about the 2 is when you are driving up to a light which just went green and the traffic just started to go. If you stay in 3rd and try to accelerate at like 2K just about everything pulls on you. That is the only time I really would like more power and the M45 would be great for that. Also with how well the cams/heads flow the top end would still be good as well.

The rotex would be a ton of fun but for what I need/want it just isn't right.

Do you know who is making the Turbo kit? I know I almost got Racing Mazda to do it but I haven't heard anything back from them in a while.

I was hoping for a kit from them too lol ok, slow 2 for ever hi hi hi

 

[zps2004]

Yea I am ok with the 2 being slow since I have the Miata as the fast car. It is funny though how I have had a number of fast cars want/try to race me. For example I had a Neon SRT-4 wanna go one time. In the mountains sure, but in a straight line? Really? Guess they like shooting fish in a barrel.

I looked last light in the engine bay and it looks like the Rotrex would fit pretty easily in one spot and the M45 would be a little harder because of the size. I wonder how Knightsports runs the pulley for their kit, or if they have a separate crank pulley.

 

[scoobs]

I'm ok with the 2 being slow to and no turbo/supercharger kit available help me save money for a second and faster project car

Diff?

The previous F Gearboxes had problem with the gears not the diff.

 

[CorkSport]

We broke more differentials than anything else in the F gearboxes. We had customers installing BP turbo engines in the 90-94 BG 323s and kept the stock F transmissions. The G transmissions were a little better but would blow the gears out of the diffs as well.

Hmmm,
That's new to me. 3 friends of mine with F gearboxes were always broke the gears(2 to 5th). None of them had a problem with the diff.

As you said, indeed from what I've heard the G was a bit stronger but also broke gears at around 280-300whp.

 

[Zenmazda]

Anyone know what kind of management knight sports is using on their sc setup. I'm starting the research for a c16-60 build. Looks realativly straight forward other than fuel management.

 

[AN7]

It is a Greddy Emanage, but i am not sure of it's Blue or Ultimate. I think they are using the blue one.

 

[CorkSport]

I asked about it a few years back and the reply i received was

"Regarding the EFI system, we use our CPU, 4BEAT, and E-manage Ultimate of Trust."

-Derrick

 

[AN7]

Ultimate it is then

What is the transmission in the Mazda3 with the 2.3l MZR? Maybe an engine swap with a 2.3l or even a 2.0l with a stronger transmission would be a better fix. NA high compression MRZ would be stronger...

I'm starting to think what if I'm staying with the 1.5l MZR I'll limit the mods to what I got + CBE...
