Dyno 1
Baseline
212 HP 167 TQ
Pros
Did you really think the B-series shootout was a thing of the past? The techs at Skunk2 provided us with their 2-liter "mule" motor for this month's power page. Utilizing a built block, non-ported head and factory cams, this engine played a perfect candidate for our power adders.
Cons
The bottom end of the block is buttoned up with an 8.5mm overbore and 91mm stroke. Numerous readers sport similar setups, which makes this Powerpage so appealing to high-compression, naturally aspirated enthusiasts-but not forced-induction fans.
Notes
This engine has been built with:B18C1 block, Golden Eagle sleeved block, Stock B16 head with Skunk2 double valve springs, stainless valves lapped with head and titanium retainer, ACL rod and crank bearings, Wiseco flat-top pistons (compression 10.7:5), Pauter rods, Cometic 81.5mm head gasket, Golden Eagle fuel rail, RC Engineering 370cc injectors, Prototype Skunk2 4-2-1 header used for engine dyno, 67mm Skunk2 Pro throttle body, Golden Eagle head studs, BHJ Harmonic balancer, Skunk2 Pro ported intake manifold, Skunk2 air intake and filter (used for engine dyno) and Skunk2 Pro adjustable cam gears (intake +3 degrees, exhaust +3.5 degrees). We tested the engine on Unocal 76's 91-octane gasoline.

Dyno 2
Hondata S200
Pros
Using a Hondata S200 piggyback management system, we selected the proper basemap, which Hondata supplied. This was entered though the ROM editor and burned into the reflashable chip using the EPROM programmer. The S200 unit allows you to set VTEC crossover points anywhere within reason using either the ROM Editor or the interface box. For competitive enthusiasts, the unit has nitrous control, shift light control and an A/C cutoff. For another $50 you'll acquire the three-step rev limiter/launch control and full throttle shift options.
Cons
The Hondata fuel and ignition tables were fine-tuned to accommodate the factory head and camshafts. We forwent a dyno sheet for this section, because the dyno graphs were inconsistent due to the roughly tuned engine while tuning.
