-what does it rev out to? (never took it over 3500)
-when does vtec engage?
-is this the ULEV setup? (has a simple VTEC valve cover on it)
-what compression ratio is this motor rated at?
-are there any pro's and con's?
-do these come with metal head gaskets like the B and D series vtec motors?


thanks alot guys!

Google is your friend.

Car Revs to 6500
VTEC Engages between 2500 to 4000 depending on load.

The ULEV Motor is the F23A4. Little bit less power, Wideband O2 Sensor, Different ECU for Emmissions, etc.

[edit] F20Z
This engine series is similar to the F20A above, used in the Honda Accord in Asia and Europe.

Specifications

Bore × Stroke: 85.0 × 88.0 mm
Displacement: 1997 cc
Valve Configuration: SOHC, 16 valves
[edit] F22A
This engine series was used in the Honda Accord and Honda Prelude S. Aside from differences in tuning, these engines are substantially similar.

Specifications

Bore × Stroke: 85.0 × 95.0 mm
Displacement: 2156 cc
Valve Configuration: SOHC, 16 valves, non-VTEC
Compression ratio: 8.8:1
Max power:
F22A1: 125 hp (93.21 4 kW) @ 5200 rpm. NOTE* The 1992-1996 Prelude S had a F22A1 but because of a different more aggressively tuned ECU (P12), the power output was 135 hp (101 kW).
F22A4: 130 hp (96.94 kW) @ 5200 rpm. The F22A4 is the same motor as the F22A1 but it has slightly more power due to a tubular designed header and slightly bigger exhaust piping.
F22A6: 140 hp (104.40 kW) @ 5600 rpm. The F22A6 is the same as the F22A1 except for a slightly more aggressive camshaft, a better flowing cast exhaust manifold, a different more aggressively tuned ECU (PT6), and a different intake manifold that utilizes IAB's and also has a bigger plenum. The F22A6 also has a windage tray in the oil pan, and stiffer valve springs to accommodate the more aggressive camshaft.
F22A7: 140 hp (104.40 kW) @ 5900 rpm (147 hp/108 kW with manual transmission)
Max torque:
F22A1: 137 ft·lbf (186 N m) @ 4000 rpm

[edit] F20B
This engine series was used in the CF4, CF5, CF9, CL3 Honda Accord and Honda Torneo from Japan. It uses a DOHC VTEC cylinder head similar to the H22A found in the Prelude but was designed to comply with many countries' sub-2.0 liter tax. The automatic transmission versions received the lower hp version (180 hp), as it was tuned for more mid-range torque than its manual transmission counterpart.

the ulev motor is a f23a4, its v-tec but a little different than the f23a1 which from your description i believe is what you have. you get a 2 hp bonus. the ulev runs a lot leaner thus, lower emmisions. you have the better motor imo.
