Yes Odyssey is Accord chassis. Could use the triptronic then. Which is the same think I believe in the H23AV Blue Top came with. Now if you want to be a custom champ get the H23AV Blue Top AWD trans and rear end and put it in the Odyssey haha

hey guys got a few questions!!! the blue top is going in my 93 hatch! im having issues finding any fuel line fitting that will work useing the h23a vtec fuel rail? i was going to run 6-an fittings off the fuel rail but i cant find a fitting that will work. i have also been looking at keeping the stock fuel lines if i was to go that route, i can run a 90-93 f series fuel rail right? i just cant find much info on f series fuel rails on h23v anywhere. also the motor has a h22 upper half and h23v lower intake manifold. any input would be appriciated. as im in the process of doing the swap now.

90-93 Accord F series Fuel Rail with the OBD1 injectors. Or H23 92-95 Prelude or Any 92-01 Prelude. They will have the inlet all on passenger side.
It still may need a custom line if you cannot find a oem solution due to the bend coming off the intake manifold. I have had custom lines made tideous going to junkyard searching different models to get the right bend of the OEM fitting cut the hose out and get it re crimped by a hydrallic hose shop. Aftermarket fuel rail and AN fitting kit from fuel filter to fuel rail much easier but will cost more...
Will need OBD1 H22 dizzy, JDM are internal coil, USDM are external. Pick your poison.
Will want P28 ecu with neptune or crome with a H23A Vtec base map. Pherable.net or Xenocron. Then upon fire up will want a knowledgable tuner, tune it on the dyno.

@ esp.net-so ill start out by giving you alittle history on the motor! this motor came out of a close friends car here in town ht screen name H22AFERIO its now a turbo h22a harvard blue 4door making 479whp on low boost levels
running a 6765. you may be familair with it? this h23v was a parts donor when he went turbo like sensors dizzy and other small things like nuts and bolts.ive seen you post in our oly/lacy/tumwater thread if that reminds you! im running chiped p28 and its tuned on crome making 227whp 172tq. i ended up using the 90-93 accord fuel rail with the h23v injectors with obd2 injector plugs spliced into the harness so i would not need to run a risistor box keeping the h23v lower half!for the oem fuel line issue i ran into i just fliped the oem fuel line upsidown moved the oem fuel filter over and worked fine w/ the 90-93 accord fuel rail. im also running a obd1 internal coil dizzy due to the eaze of plugging strait into my existing harness! fired it up last night runs great! i do got one question for you though what degree is stock ignition timing for this motor im assuming to use the obd1 h22a 15 degrees for reference?

I am no tuner and couldn't answer that ask James @ speedfactory he tunes all my cars... and I am sure he can burn the chip to purchase if you'd want to have the whole tune. I do remember him stating it took more timing then norm H22 stuff.

After doing research on the H23A, I gave up. One thing was no matter what, if I wanted parts it would have to be in Japan.

help need
I put the h23a vtec into my 00 accord changed it to obd1 b/c f23 ecu ran like crap and I could not get PCB ecu to run my fans.
now that I changed it to obd1 I have a cel code 9 which is cylinder position sensor, I changed the dizzy which I could not find the one the engine came with anywhere. so I went obd1 prelude did not start swapped cyp sensor into the dizzy that came with engine started but still got code.
The sensor ohms are around 400. I traced wires down to conversion harness still 400 after conversion harness dead just got the conversion harness.
so what should I do to fix this?

Need to use OBD1 H22 Dizzy with OBD1 ECU. OBD2 vehicles have crank angle sensor those wires from the harness on timing belt plastic area need to be re-routed into dizzy. Ask Rywire.com exactly what to do. They may be able to even make a custom plug and play deal.

Re: JDM H23A Vtec Blue Top Mystery Motor, True Facts, Questions?
mine doesnt have the crank sensor either. Using my stock h23a1 harness with H23a1 dizzy, H23a1 upper intake plenum, and wiring in v-tec. Also added a v-tec oil pressure switch since it doesn't come with one. Also converted my chipped p75 to p72. Don't know why people are having problems with this motor. Not rocket science.... but i have to admit this thread didn't help much. Wasn't till i got the motor on a stand that i noticed the stuff that needed to be changed but still nothing hard.

Re: JDM H23A Vtec Blue Top Mystery Motor, True Facts, Questions?
Its simple best way to get power is to make it OBD1: For tuning reasons. If you have emissions not sure if you can go OBD2-OBD1
Normal H22A OBD1 or 2 Intake Manifold, sensors, fuel rail (injector angle difference and diameter)
OBD 1 H22 Injectors
OBD1 H22 Distributor
P28 Ecu Neptune or Crome H23A Vtec Base Map Xenocron and Pherable sells ecus ready to go...
OBD2 vehicles: Emissions
Swap top plenum for OBD1 and IACV
Should be able to use BT injectors, fuel rail etc
Crank Angle Sensor OBD2 H22A4 Oil Pump
or re wire into distributor with OBD1 distributor
Might be able to use stock ecu.

There is no crank angle sensor on H23AV BT, F20B, Euro R and Type S. None used the crank angle sensor from what I am aware of. (sensor located on timing belt plastic)
