Supercharging a 327i E30 !!!

[sindako]

Hello THere Zoners .
I Need some Info On Boosting An M20B27 bottom end with M20B25 Top .

I Have The SETA Pistons with 2.7 Crankshaft .

I was Thinking about installing a supercharger .
.
It'll take alot of work cause i don't want to remove my AC .
So I'll Have to Use another Pulley On Top of the Powersteering Pump Pulley .

Or My Other Option is A 272 degree Cam From Schrick or IE engineering , with branch Headers .

What do you think is best for a Daily Driven .

I Know the super charger Needs alot of Gas Money .
Also How About Gains ???

272 cam with Headers ??

Or

Supercharger (Twinscrew) ?

Also If Super Charger , What Pulley Setup should I be Getting .

Ratio Of Pulleys .
Like 1:1 , 2:1 , 3:2 , 3:1 ???
I know it effects Everything with Changing The Pulley Diameter .

In Adding to What Injectors should i install .
I Was Planning on Using an Electrical Clutch on the Supercharger so i can Turn It On And Off Any Time .
with 2 M20b20 injectors turning on only while super is On , to Pump gas with Air within the Inlet Manifold .

Any Ideas .

And Please Advise me , Cam with headers Or Supercharger .

I've Seen the IE 272 Cam for almost 230 quid , and Headers also for something like that so it'll be around 500 , Or Should i Invest Those 500 on Forced Induction ???

Cheers .
