Default H23a Vtech Swap in a 00 civic SE??

Hey guys can anyone help. Here is what I know so far.

Engine mounts needed
OBD2B to OBD1 harness conversion
Also the shifter and cables
Now what about axels? (looking for any combination to work)
I have heard about accord axel (for the axel swap) I have these in hand any insight would be great.
Is a slim Fan a must?
What about pwr steering? Can I keep it if so any modes needed there?
Thanks

Civics didn't come with H motors. You want the Hybrid forum.

Mounts, 89 integra axles with accord half shaft(Many axle combinations but this worked best for me), drilling and cutting into the chassis for the H transmission, exhaust welding, smaller performance radiator, and pcm. Best bet is to get an obd2 motor with an obd2 pcm to pass emissions.

ebay ones pretty much looking on what to do with axels I am hearingg H inners with B cores and outters.
What about the engine harness the distributor has 2 plugs and 10 wires where as the civic one has one with 8 wires.
Any insight or anyone can direct me to the right place would be great thanks

I'd just like to interject by saying:

If you haven't heard of h2b swaps, you should do a lot of reading in the h2b FAQ and h2b discussion threads at the top of this forum before continuing with your future plans.

Correct. There's really not any point to doing a regular h22 swap anymore. The h2b is better on so many levels it's not even funny.

i loved my H2B 93 Si H22A and 01 ITR tranny thing was amazing

you should read up on h2B the kit itself is pricey but its so worth it in the end and you dont have to deal with cables you have a solid shift linkage

That h2b **** is over rated the t2t4 or t2w4 lsd euro r trans has similar gearing but the b16 trans has the shortest gears imo. If your staying straight h swap than use a 93 accord half shaft and 92 integra axles. that works perfectly no need to swap parts or anything straight up put in. The shifter cables are easy to put in just look at the hole where the civic shifter is cut a square around the circle and put the h shifter in. Cut another hole about 8 inches in front of the square hole and route your cables through. Also mark the spots where the h shifter bolts on to (the 4 holes to hold the shifter in place).

There is a all motor prelude that's doing 11.85 1/4 using the lsd h22 trans so there's my point.

You're also ignoring how silly hard to find and expensive T2T4 transmissions are.

And gear ratios are similar? Oh, really?

T2T4:
3.285 1
1.956 2
1.344 3
1.034 4
0.787 5
4.266 final

96-97 ITR/b16
3.230 1
2.105 2
1.458 3
1.107 4
0.848 5
4.4 Final

GSR
3.230 1
1.900 2
1.360 3
1.034 4
0.787 5
4.400 Final (4.785 for 98+)

I would say the b-series have better gearing. The Final drive difference alone pushes them way ahead. Not to mention the axles will sit properly, whereas with a regular h22 swap with h22 mounts and the h22 trans the axles will NOT sit properly. Thereby requiring careful use or aftermarket axles.

The h2b is worth it, plain and simple. The swap bolts in with b-series mounts, b-series axles, and you get cheaper/easier to find transmissions with better gearing.

If he used a b-series trans with a QSD kit he'd probably shave a second off of his 1/4 mile time like all the other h22 guys that switched to H2Bs did.

Thanks for all your info guys on the h2b but for now this will be a h23a straight swap, I am helping firend out and he has all he needs just looking for some help installing it.

Anyone know how I should wire the distributor, the h23a has 2 plugs with a 8 and 2 wire plug where as my civic harness has 1 plug 8 wires? anyone? thanks

There's no "for now" really on an h22 swap. You have to get special mounts, cut a hole in the floor to run the shifter cables, and likely get expensive aftermarket axles to run regular h22 swap.

If you like you're friend you'll tell him all of this and tell him how tragic a mistake it is to do a regular h22 swap. My 2 cents.
