H22a8 98' ODB2 engine into Prelude gen 4 pls help
Hi,
I know that there were several posts about such kind of swaps…. But I couldn’t find all the answers that I need about it.
First of all I describe the situation:
I have chance to get 98’ H22a8 Type R engine from 5th gen prelude (UK type with driver position on right side) I will be swapping it into Prelude 4th gen H23a2 (European type with driver position on left side)
I made list of parts which I will need from my donor prelude:
1. Engine (what about wirings?)
2. Tranny
3. Generator
4. Collector
5. Axel shafts
Other parts needed:
1. P13 from gen 4 Vtec or P28 ECU
2. OBD2 to OBD1 converting kit
So here are few questions for which I couldn’t find answers:
1. Will my new engine fit in 100% ? What about engine mounts can use mine?
2. Can I use mine H23a Axel shafts and generator
3. In post https://honda-tech.com/zerothread?id=1410996 I found that I need
345cc obd1 injectors from a 4th gen obd1 vtec prelude as well, but why I cant use obd2 injectors which will come with my new engine?
4.What other parts should I take from my donor car?
Thanks for help and sorry for bad English
Regards,
Grobas

Since your car is left hand drive and the donor is right hand drive you will need to use your stock engine wiring harness and put it on the new motor.
You might still want to get the rhd harness, because you will need to put some of the obd2 plugs on your harness.

1. as far as I know, h22 and h23 mounts are the same.
2. you can use your h23 axles and alternator(generator)
3. The '98 injectors are a different size. The car will run like crap if the ecu(which will be obd1) thinks its running 345cc injectors but its only running 290cc. You want the injector size to match the ecu, basically.
4.The things I am not familiar with is whether or not the h23 powersteering pump and a/c brackets are the same. These are things you'll need to research.
Maybe someone with experience can chime in.
Good luck.
