Well with my h23a1 swap on my 93 Accord done its time to work on my 94 Prelude i had a Thread Asking for help with a No start on this and found out the engine was bad i Pulled the Engine after word and had it sitting since then. The Vin say's the car had a 2.3 in it when i got it It had a f22b1 Vtec Now I'm Putting in a h22A lol btw the body only has 68K miles on it crazy. i found a good h22a That was in 5thgen Prelude for 600$ ill be doing the Engine Change over the next month So pics and Questions will Follow.

 

Engine Out

h22a

 

Alrighty First Question I need Fuel Injectors i think these are Peak And Hold id like to stay as stock as possible cuz i cant tune a Auto So is there a Good set on eBay or should i just buy em from auto zone? Or Is there any other Honda/Acura that have the same Injectors as the 2.2 DOHC Vtec Prelude That i can pull from I have the f22b1 and 96 h23a1 injectors sitting around will ether one work?
Second I need to wire up Vtec i read i can hook it up in the engine Bay cuz theres lines from the ecu already at the shock tower does someone know what ones and pics would help also?

 

If the engine has the original injectors, you would just need to delete/ loop the resistor box to have that work properly, otherwise only a set of US or JDM H22A/ A1 injectors will be what you need.

In the faqs there is a "how to wire vtec" thread, should have all the info you need. If still not working, let me know and I can try to find the pics I took for someone else a few years ago when I did my first swap.

And my fav color 4th gen!

 

well i have decided to also do a 5speed swap at the same time i looked on the FAQ for preludes i dont see any Links for auto to 5speed swaps for preludes i would like a Parts list i need to get i found this 96 5speed h23 prelude in the junkyard untouched so im thinking of taking everything from it When i was shifting the trans it seems to go into every gear but is there a way to see if the trans is good with out it moving?

 

well i pulled the shifter/w the linkage The clutch pedal(should i also get the brake pedal it looks like it will fit with out the 5speed one?) also the 5 speed center console. ill be going back to pull a few more things anything else i should take? Also ill be need a 5speed trans i think i want the f22a1 5speed trans due to me wanting to turbo the car in the future but it will see alot of highway driving i dont know much about final drives that ppl always talking about. How about would i wire the car up to allow the reverse light to work in reverse also i read sense my car is auto i need to do something so that the car will start cuz it think its in gear. thanks for the help

 

anyone?

 

my f22a1 5speed trans cleaned off somewhat

my new flywheel and clutch

my trans painted and my new clutch master , slave and clutch line

engine painted and cleaned up

engine and trans together
its in

found a fiberglass hood for 50$ at junkyard and a random cat chilling next to my prelude
more pics to folo soon im still waiting to get injectors a Ecu and a few other things

 

i got a question is the cat back exhaust the same on the h23a1 and h22a1 preludes?

 

yes

 

Starter in
top part of my headers on
mocking up AEM intake
had to put her outside cuz i had to work on customers cars

 

i need some help it wont start lol i think i got a problem with both spark and fuel first when i have someone cranking it i pull the plug and see that its sparking but i spray some starting fluid in there and its not firing and i checked all of my fuel injector connectors none of em have power with the key on i pulled the coil off and found that the coil has 4 pins that go to the harness but the harness connectors only have 3 wires coming out of it it has 12v power to one wire im going to check my fuel pressure today when i got to the shop cuz i cant hear my fuel pump prime i hear my main relay click after i turn the key also another think the check engine light should turn off after a few secs the key is on right? any and all help is welcomed

 

fixed it !! firing order was wrong and fuel pump was not working now i found out my brand new intake gasket is bad fml sprayed some water on it and it lowerd the revs

and that's where its at atm i still got to fix my cooling fan i need to wire them up the guy before me ran wires off the stock harness so that it turned on with the key but i don't want that and its been hacked up so if someone can show me a diagram of how to wire them up to use a stock fan controller like the one on the thermostat housing and to have a switch for me to run in the cabin. also the harness i used did not come with a IACV on the fuel connector harness so what pins at the ecu do i need to use for it?

bump still looking for help on wiring up IACV and Fans P13 ECU

 

looks like could be a fun build

 

Can't help with the IACV but the fan is pretty easy- the fan switch near the thermostat simply passes ground through it to the fan relay. From what I can tell by studying the wiring diagram, the ECU doesn't need to be involved. I have a feeling the only reason the ground signal continues on to the ECU is probably to tell it to throttle up a little for the electrical load. The factory radiator fan timer is what passes on a 12v+ signal to the relay. You don't need to have this, just jumper over the 12v+ wire that came/would have come from it going to the relay to another source, such as the main power wire flowing through the relay.

 

.:FFS TechNet : OBD1 ECU Pin out Schematics :.

iacv is A9

You can look on your old harness connector to see which side is switched battery voltage(yellow black) and which side is A9.

 

what is the easiest switched power i can use in the engine bay and i wired up my fans today woot to use the stock fan controller and have a switch in the cabin ill post up a diagram i made for it

 

i got the IACV and Fans wired up now a new problem i got code 10 and 21 10 is for Intake temp sensor and 21 is vtec (1 wire one) And its running super rich that its only running on 2 cylinders # 1 and 4 spark plugs are always wet when i pull em and not firing i pulled the wire with the engine running and it made no difference to engine rpm. 2 and 3 are blk

I have replaced Distributor, Spark plug wires, Spark plugs, 4 new fuel injectors yes there for h22a1 i replaced the ITP sensor and the code is still there if someone could tell me where the 2 wires go ill back probe em and check if there working

Also im thinking about getting a ecu with hondata em i able to use my JDM p13 for that or do i need a different ECU and where can i get One?

 

search obd1 pinout, it will tell you where all of the wires are on the ecu side.
