Hey guys, I'm new to the forum, but not to Honda's (relatively speaking)! I have a 1995 Honda Civic EX coupe with the stock D16Z6 in it. The car really hasn't seen many mods outside of a Magnaflow 2.25" cat-back exhaust and an AEM short ram intake (if you call that a mod). The chassis/engine has 153,xxx miles on it as of now, and everything runs very well. I DO have A/C in the vehicle, after picking it off a scrap car for *free* this summer. I also live about 4,500 feet above sea level, and all gas stations carry 91 octane for "premium" fuel.

This car is my DD, and will continue to be for the next few years most likely. I am tired of driving on the freeway and coming to a small hill and having to downshift just to keep up with the speed limit. It's a thousand times worse once I add my bike rack and bike!!

So I have decided I want to build a new engine that gives me a large improvement in torque with a little more top end zip as well. When I first started researching I locked in my numbers at 200hp and 150ft lbs to the wheels.

This is my current design setup:
-B20 block
-B16A2 head (want to run OBD2 if I can??)

For Block:
-Forged Pistons (thinking Wiseco)
-Forged Rods (brand undecided)
-ARP Rod Bolts
-Cylinders will be honed (sticking with standard bore if possible)
-Rod Journals Honed
-Crank Main Bores Honed
-Rotating Assembly Balanced

For Head:
-Keeping it stock (for now)
-Machine shop will run vacuum test, crack check, and inspect for flatness

Miscellaneous Parts for Rebuild:
-ARP Head Studs
-Head Gasket (Cometic Probably)
-Main/Rod Bearings and Thrust Washers (ACL Maybe?)
-New Valve Seals for Head (OEM)
-22 Tooth P72 Water Pump (Gates)
-P72 Timing Belt (Gates)
-P72 Oil Pump (OEM)
-Premium Thermostat (OEM)
-Magnetic Drain Plugs
-NGK BKR7E Plugs
-All New Bottom End Gaskets
-Hondata Intake Gasket (So I've Heard?)
-Injectors (Size and Brand Unknown)
-Upgraded Fuel Pump (255lph probably)
-Vtec Conversion Kit
-ECU (Haven't Even Begun on This...... )

I did a lot of thinking, and with a B16A2 head I didn't see how I could make 200whp without extensive head work and high compression (12+) and keep it reliable, comfortable/streetable as a DD, and run 91 octane. So I have turned to running a forced induction setup. I know that the block is less than ideal for boost, but I figure with a thorough assembly of quality parts, a small to mid-size turbo with quality components, and extensive tuning I could easily reach my goal numbers and keep it reliable and streetable as a DD.

What I could really use some help with:
-Engine Management/ ECU
-Running OBD2 (Every build I've checked recently run OBD0 or 1 it seems..)
-Determining what Turbo to Run (I'm a noob with turbos..)
-What C/R to Run (I was thinking Wiseco 9.26 C/R pistons over the 8.28s?)
-Breather Box -- What do you really recommend on this?
-Which Turbo Manifold to Run
-Some Type of Wideband to Monitor A/F Ratio

Please let me know if there's anything that I may be overlooking, or problems that you may see with my current setup..... Any and all questions, suggestions, or critique is much appreciated!!
