Okay, first things first....anyone who puts a supercharger on a 1.6L SOHC engine is stupid! Superchargers are based on the speed of your belts...most superchargers are used with bigger engines...V6 and V8....If your looking for big numbers go TURBO!!! Gettting your D16Z6 major power is mostly in your tuning...everyone can argue about what to do---but most will agree that tuning is the most important part of getting big hp numbers from your car...and the best way to prolong your engines life. Now, I know you arent looking to spend a lot of money...so my opinion would be Cold Air intake, 2.0" to 2.25" piping for an exhaust, and turbo manifold...the moanifolds are mostly "log" manifolds, but will give a little more power.. You also asked what it would take to turbo you car....I have a 1995 Honda Del Sol with a 1.6L SOHC VTEC D16Z6....and I have my car turboed...I wasnt going for 400+hp...just for good 'get up and go'...my car dynoed at 266hp...so its not a monster....but if your looking to turbo your D16 for cheap I can help you out....I turboed my car for under $2000.00. which...over all isnt bad....Here is a list of everything I have dont eo my D16Z6...
p.s. youre going to want to build bottom end not so much top.
CP pistons and bearings
Eagle Rods
metal head gasket
Front Mount Intercooler with piping
HKS blow off valve
walbro fuel pump
450CC injectors
ARP head bolts
XTD Stage 3 racing clutch and a lightened 9lbs. fly wheel
A T-25 Turbo (with internal Actuator (wastegate) )
oil feed line kit
and finally a Hondata S200 system with boost option enabled.
Thats everything I have for my turbo set up and I am running around 266 hp....I did all of that for under $2000.00......If your looking to turbo you car for around that money....let me know, I can hook you up with places to get good deals...and VERY RELIABLE MERCHANDISE!
Goodluck
