I'm trying to fit a jdm h22a type s into my 1992 prelude si. Will it work and how much more will it cost than a standard h22 conversion?

Don't waste your money on a type s.. for the same cash you can get a regular H22A to whip a type s's ass.. as for the other questions:
Any engine swap write-ups?
Some/all 4th gens factory wired for VTEC?

have fun!

oh yeah, and ignore what the first thread says about the engine mounts being different on the different motors.. I assure you they are all the same.

When did the h22's go to 200hp? Should I get that engine or should I get a 95 jdm h22 so I have obd1? And once again, do jdm engines have obd?????????

no, jdm engines don't have obd.

Are you sure? Where can I find info on this subject?

why do people say jdm don't have obd? For some reason... i have a few b16a here... cable and hydro... half the hydros are obd-i and the other half obd-ii from the new model civics... the ecu have different wiring?

So do JDM engines have OBD or not? I know someone can give me a second opinion. Cant they????

ExodusFX · 06-05-2002, 12:32 AM

i was just always told that jdm h22a's don't have obd.

knightluder · 06-05-2002, 12:35 AM

Do you have any sites where I can confirm this?

Uh, they have OBD.
Hense the reason for having OBD1 to OBD2 quick wiring harnesses.

This is something I need to know, I'm having problems with my car right now...
JDM H22 from a 96 - I've been told 96 has OBDII, thats why it's chirpin at me
I'm getting a code 41 - heated o2 sensor
From what I understand, OBD2 requires 2 o2 sensors (primary & secondary), and OBDI requires 1
Please correct me if I'm wrong, cause I need to get rid of this CEL. If my car isn't rigged for 2 o2 sensors, how do I go about fooling the ECU into believing I am running 2?

JDM do have OBD and JDM H22A has 200ps (~197hp).
