H22a into a 94 Integra LS - Just a few questions - Need clarification
I know that this is the same as the EG swap in the FAQ, but I am having a hard time weeding through the 100+ pages of comments, discussion and BS in that thread. I just have a few questions that I am hoping you all can help me out with.
1. I want to keep PS. What do I need exactly to do so? 97-01 pump and nothing else? Lines? Brackets?
2. I want to keep AC. What do I need to keep it? LS compressor? H22 Compressor? What lines? Brackets? Do I use the stock Radiator and fans?
3. I already have AVID mounts, are these any good? What should I expect from them?
4. I am using self made custom mounts with 90-93 Teg outer and 92-96 Prelude outers. Is that correct?
5. I am going to use the stock LS harness and modify it for the H22a?
6. I have to drop the car over the engine?
7. I have to trim the passenger tranny mount?
8. Rather than adding a resistor box for the Injectors could I run the H22a4 injectors instead? (they don't require a box) I would just have to change the LS injector plugs for the H22a4 injector plugs right?
9. I am running a chipped p28 so it will get tuned on crome
10. Is there anything I am forgetting here? Any advise recomendations would be great.
Thanks everyone for your help and please bump this if you read it.

for the integra since you have more room up front in the engine bay then a civic you can use the stock h22 92-95 pump or the 97+. To make the 92-95 pump work, you need do a little grinding to the pump itself (very easy) to make the integra ps line fit. If you what to use the 97+ h22 pump you need to have a 97+ prelude line (part the bolts onto the pump) braided/welded in place of the integra line. imo the 92-95 is the easyer route to go.
Here is a picture when i was using the 92-95 pump (im now using a 97+ since i needed more room when i raised my engine)

2. I want to keep AC. What do I need to keep it? LS compressor? H22 Compressor? What lines? Brackets? Do I use the stock Radiator and fans?
hcp makes a mount for the d-series compressor so you can keep you a/c in a civic. Unforantly there isnt a company that i know of that makes one yet for the integra. I bought a modded hcp mount from a user here on honda-tech that made it so the integra compressor would bolt up to the h22 engine. basicly all thats different is 2 out of the 4 mounting bolts have been moved to accept a integra compressor. I also heard the h22 compressor or d series compressor will work with some custom work.
3. I already have AVID mounts, are these any good? What should I expect from them?
avid mounts are not the best from what ive read (just from what ive read, not putting them down) I would invest in hcp or hasport
4. I am using self made custom mounts with 90-93 Teg outer and 92-96 Prelude outers. Is that correct?
yes, you could use 90-93 outers with 92-95 prelude inners for axles but i would suggest 89integra outers with 92-95 inners. seems to give good results and ive never had a problem
5. I am going to use the stock LS harness and modify it for the H22a?
yes.
6. I have to drop the car over the engine?
you can install it like that or drop it in from top (i put mine in from top)
7. I have to trim the passenger tranny mount?
yes, altho it depends which mounts you use. I think from what i remember with hasport you remove the passenger mount and bolt in there new one.
8. Rather than adding a resistor box for the Injectors could I run the H22a4 injectors instead? (they don't require a box) I would just have to change the LS injector plugs for the H22a4 injector plugs right?
not sure, but adding a resistor box is very easy.
9. I am running a chipped p28 so it will get tuned on crome
most people will run a p28, so they dont have to worrie about the knock sensor and egr, but i recommend a p72 or the stock p13 since you can keep you secondaries if its going to be a daily driver
10. Is there anything I am forgetting here? Any advise recomendations would be great.
Basicly, if you want it done right. Take it one step at a time and double check all your work. My swap took me quite awile since i only worked on it on the weekends and just took my time. I made sure to read up on everything and was prepared when i went to go touch

Should I use an Integra Radiator (planning to get an Aluminum if so) or is it possible to use a EG Civic half sized and still keep AC?
Thanks again

Im using a Fluidyne full size integra radiator with 2 slim fans infront of the rad. I also have a/c, p/s. With a halfsized rad you "should" be ok, but i cant really say for sure
