B16a2 N/A is a beast of a motor, but making power costs big money. I had a proper built 1999 Civic Si running a B16 that eventually grenaded. It ran at 11:1 CR the Rocket Motorsports cams/valvetrain, Omnipower valves, AEBS manifold, JDM DC header w/ 2.5 inch collector, obd2-obd1 conversion chipped to tune with uberdata, and that's about it. We did take it all the way down and use ARP rod bolts, full race main bearings, balanced and blue printed the bottom end, stock pistons w/ a .025 over bore, cp rings, and shaved the head a bit. That gave me a nice platform to start from and be able to handle the revs. That put down 178whp@9700rpms/103wtq. Not nearly as much power as the 4E can make being turbo'd, but going no lift through a corner at 90 mph is a feeling most turbo cars cant give you.
Now ive smartened up a bit and started with alittle better platform the LSVtec B18C1 bottom end and a B16a2 head. the new build assembled with ARP rod bolts, ACL race bearings, OEM honda rings, PR3 (b16a2) pistons for higher compression. New lower gasket set, new type R oil pump shimmed, NRG aluminum cam seal,
PR3 head milled .030.,bronze Ferrea valve guides, did a three angle valve job to clean up the valve seats, Ferrea valve stem seals, REV stainless valves, Rocket Motorsports M22X cams, Rocket Motorsports LSX valvesprings and titanium retainers, Skunk2 cam gears, AEBS intake manifold, Honda Prelude injectors, Hondata Heatshield intake gasket, K&N typhoon cold air intake, SPARKS racing header (copy of the SMSP tri-y), NRG catch can custom mounted, custom straight through header back exhaust from MSPi, skunk2 obd2-obd1 conversion harness chipped P28 ecu running crome engine management. Tuned for a VERY conservative setup running 13:1 A/F, stock ignition timing, and -1, -1 cam timing made 181whp 112lb/ft tq on MSPi Dynojet. The car has plenty of power left in it as evidenced from the fact it made 150 on low cam only and the motor doesn't make peak power until 8500 rpm. For a B18c1/b16a2 hybrid with a 4-2-1 header that is very high for peak power.
