Twin Supercharged Miata Build (56K Beware)
 

Mods move this if it goes somewhere else. It's my build thread, but there's plenty of fabrication going into it.

So I'm starting the build for my 99 miata. It's a 16 valve 1.8 liter cast iron block aluminum head 4 cylinder. I'm putting on a pair of 1.0 Liter twin screw IHI superchargers removed froma mazda Millenia S. Stock the motor made 110whp. I'm hoping to make 300whp and have headroom with the system. I know this is a turbo site and all, but trust me, this build will have the HMT spirit.

Goals are for the car to appear 100% stock when finished. It won't sound stock or perform stock, but it will look stock. The engine will be stock internally. Well, I did a lot of custom head work a while back but the parts are all OEM. Stock valves undercut and polished, reduced S.S radius, etc. Short block is 100% stock.

Here's the 20x12x3 core intercooler mounted between the condenser and radiator. Pipes will exit from the top inside the engine bay. No pipes hanging down below the car. Can't see the IC with the bumper installed either. All factory plastic under tray ---- fits with no modifications.

Adapter I made in a lathe. This will bolt into my SC pulley that goes on the crankshaft and will spin the trigger wheel for my ignition system. Using a 36-1 wheel and EDIS with Megasquirt 2 V3.0 standalone.

Made the flanges and outlet things for the SC's. They bolt on and have a 2.5" pipe coming out of the discharge.

Made a flange to bolt to the intake side of the head. Gotta open up the ports still.

Then welded some U shaped things on it.

I have many parts for the car. The coldside SC bracket took a while, but I knew it would. Gonna start on building the intake manifold tomorrow. It will be between the SC and the head.

Not bad the build looks good, post some pic's of the car.

Had the car 2 years and these are the only two pics I have. Gotta get some better ones soon.

Ain't she cute? Car will look just like this when it's finished.

man if you dont mind me asking what exactly the point in running dual superchargers. i thinkits cool and all i just dont see the point of it. i guess maybe have different sized pulleys on them so one will push alot of air in the low rpms and one will pump it out at higher rpms. if thats the case then you can disregard my question. but good luck

for baller status, duh

Re: Twin Supercharged Miata Build (56K Beware)
 

wheres the second sc going? i dont really see room for it....

Re: Twin Supercharged Miata Build (56K Beware)
 

have you done any calculations on the pulley ratios or the calculations for the final boost is going to be?

Re: Twin Supercharged Miata Build (56K Beware)
 

Where is the turbo going? >:D

Re: Twin Supercharged Miata Build (56K Beware)
 

That looks pretty sweet so far. Will those superchargers even be able to make 300 whp though?

Re: Twin Supercharged Miata Build (56K Beware)
 

This may sound stupid but it the second SC going to be on the exhaust side?? with the inlet being exhaust fumes and outlet of sc going to exhaust??
