There's a reason you hardly ever see a supercharged inline 4 cylinder.

Not to mention, to my knowledge, there are no SC's for the 420a.

If you're talking about the exhaust sound its bc superchargers are belt driven and nothing in the exhaust system changes (except the flow).

In a turbo system, the exhaust gas passes through the turbo and the flow rate is increased.

It might be a little late for this, but, I am planning to do this sort of thing to my own 420a.
One thing I had a problem finding was the high-impedance fuel injectors
I found some here: http://www.turbosystem.com/auto/engine/injectors.htm
They want about $80 per injector.

Besides the fact that they are 1000cc injectors and are ment for boost presures up to 30 psi... no. (they actually might be the wrong impendance. not sure).

Im saying they're way too big. Way... to big...

I must have missed where you mentioned 1000cc injectors.
That is WAY overkill.
420a engines require high-impedance injectors, low is for the 4G63.
There ia a way to get around that, and use low-impedance, but you have to remove an electrical component, and still need a SAFC to properly tune, and then there is possibilty of burning up your ECU as well, and you would need an SAFC to properly tune the engine no matter what.
Buy the right thing the first time, and you won't regret it (don't try to save $33 on a fuel fitting, pwee and EMC3kGT know what I am refering to).

Not necessarily an SAFC but some kind of fuel management and tuning device. SAFC seems to be the most popular inexpensive one.

SAFC dosnt have brands.. it, in a way, IS a brand lol. Apexi SAFC is the full name. there are 3 models. SAFCI SAFCII and AFC Neo. It stands for Super Air/Fuel Controller. It is a piggy back system and, to my knowledge, is really the only one like it. There are other piggy backs out there but none with the capabilities of the SAFC. Another option which is an even better option but WAAAY more expensive (Close to $1000) is the AEM EMS (AEM Engine Management System) It is a stand-alone rather than a piggy back, so its tuning abilities are limitless.

Thanks for clarifaction. I feel like an idiot now. lol
I had a good idea what it was, I just didn't know that Apex was the only one that made it. And screw buying the AEM one. I but it is an awesome unit, but for a grand? Uhhhh..... I ain't THAT rich.

Just keep in mind that the AFC can only tune for +/-50% of the factory injector flow rate. meaning. If the factory injectors were 450cc, the biggest injectors they could compensate for are 675cc.
