Exclamation h22 94 5th gen.

im gonna drop an h22 turbo in my car cuz im sick of all these vw taunting me and knowing that my stock f22 isnt enough.. i just had a couple of questions about the motor.. aside from the motor mount and ecu needing to be swapped will every thing else pretty much bolt on and funtion(i.e. tranny/drive shaft ex). whats is the difference between the h22 and h23(i assume h23 in manual). same with h22a\h22b. is that vtech and non vtec... does my h22 need to be from a 94 lude or year dont matter? will radiator need to be replaced or fan if so with what or whats a good upgrade for that.. which is better for an accord.. a b16 or an h22.. i dont care what u think about me or my car i am just looking for sumone to help me out with answers or suggestions. thnx for taking time to read this.

Don't turbo the h22. It is a waste of time. Turbo the f22 in your car and you will get more out of the money invested into it.

h22 and h23 are the engine codes. The transmission depends on the model. Both motors can have manual or automatic transmissions. All transmissions from F and H motors are swappable. You can use most of the stock stuff in the car, but it is recommended to swap out to prelude trans and other parts.

There is no such thing as a H22B motor. All H22s are vtec. H23 motors can be vtec or non-vtec. You can use any H22 motor. Just remember, vtec motors require extra wiring.

First of all, why a b16 and not a b18. Secondly, to get a b16 in a cd5, then you would need to do more work than a h22 swap for a less powerful motor.

Parts List
a) OBDI ((91)92-95) H22 complete engine, including;
-Intake Manifold, w/IAB box & solenoid
-Throttle Body
-Fuel Injectors, Fuel Pressure Regulator
-Good Knock, TPS, IAT, VTEC Oil Pressure, MAP (?) Sensors, VTEC Solenoid, EGR, FIT, IAC Valves
-Engine wiring harness, uncut or cut with sensor plugs intact and alternator wiring
-Power Steering pump & bracket (If keeping PS)
-Exhaust manifold & downpipe, OBDI VTEC Prelude
-P13 ECU or a chiped P28 ECU
-1-5 wires, depending on make, model and technique, will need to be run from the ECU to the VTEC Solenoid, VTEC Oil Pressure Sensor, Knock Sensor and IAB solenoid (exc. EX w/A6) on the new motor
-Don't jam new sensor wires into ECU harness plugs made for pins, so you need an extra pin for each wire added above. Cut an ECU connector and a few inches of wire from any pre-96 OBD1Honda/Acura. This is a junkyard part worth basically nothing to them.
*Optional but preferred; H22 Crankshaft Pulley, Flywheel, Alternator,Starter,
Transmission (LSD if you can find one),(for these, F22,H23 & OBDII H22 parts are ok too)

b) Accord Keeper Parts;
-Front Waterneck & temp sensor, the thing on the head that the upper radiator hose goes to
-Fuel Rail, CB7 or 92-96 US Prelude (If your H22's rail is timing side inlet/JDM)
(Use H22 Fuel Pressure Regulator)
-A/C system, Pump & Bracket (If keeping A/C)
-Alternator & Bracket, or 92+ Prelude
-Engine Wiring Harness
(This will be modified to fit your new engine, note that almost everything reaches on H22 without cutting if you unwrap your harness and reroute/retape it)
-Axles & Intermediate Shaft
-Engine Mounts (Check condition before reinstall)
-Some of the F22 timing parts can be used for the Manual Tensioner Conversion.
-You can keep your Transmission if you want, though a Prelude one would generally be faster, there are many options

d) Keeping Power Steering:
-92-95 H22/H23 Prelude Pump, bracket and hardware, as listed above
-Complete 92-95 DOHC Prelude Power Steering Line, HP side
-discontinued by Honda, available at autoparts stores
-I found one at Advance Auto for $100.99 (I'd swear it was around $80 before)

*These parts are necessary to ensure reliability, at least in my opinion.
I would not want to do a swap without replacing this stuff.

a) NEW H22 Parts;
-Timing Belt
-Balance Belt
-Water Pump
-Thermostat & Gasket
-Fuel Injector seals, cushions and O-rings (if switching fuel rail), including FPR O-ring
-PS Line to Pump O-Ring
-Valve Cover Gasket Set w/ Grommets and Spark Plug Tube Seals (Needed after Valve Adjustment)
-Exhaust Gasket, Downpipe to Catalytic Converter
-Spark Plugs
-Oil Filter
-Distributor cap and rotor
-Spark plugs and tubes
-Front Balance Shaft Oil Seal Retainer Kit
(Keeps your balance shaft and seal from popping out)

b) All (H23) Manual Tensioner Conversion Parts.
-some F22 timing parts are reusable here

c) NEW Accord Fuel Filter

d) NEW 92-96 Prelude Radiator Hoses and hose from heater core to water pipe
-Your existing Rad hoses MAY reach and be reusable if good
-The above heater hose often won't come off without cutting during engine removal

There might be some stuff missing.

However, from the questions you are asking, it seems like doing a motor swap might be out of your skill range. But I could be wrong. This swap is a big undertaking for someone who has never done a motor swap before. But like I said before, if you want more power and your current motor is good, then turbo that thing. You can get a turbo manifold from a first generation mitsubishi eclipse. It bolts up to the F series motor. Get a good turbo and then you can surprise all of those vw guys. Good luck. Any more questions?

Wow. Very helpful. So you recommend boosting a sohc vtec f series motor? Because I don't. The OP should stick to non-vtec f series motors if the person wants to do a turbo.
