just pulled my d16 out and chose the b18b for replacement and I have some questions:

1.) What axles are needed? Hasport sells axles for the b18 into an EF application, but can I just get a pair from my local junkyard from a teg? or do they need to be specialized like the one hasport sells. These Hasport axles are expensive as hell: http://hasport.com/shop/produc...d=105

2.) I was looking at the thread where people bought there motors from, but the poll seems a little out dated. I'm debating between HMO and Sohfast. I've heard good things about HMO, but Sohfast seems to be also popular.

HMO sells both the JDM and USDM b18b:
30007 - B18B 94-01 (LS) Complete Change Over
145Hp 127Trq 9.4 Compression (JDM)
142Hp 127Trq 9.2 Compression (USDM)

3.) besides compression ratio, what are the differences between JDM vs. USDM? JDM claims to produce 3 more WHP, does it have different internals? Which would have lower mileage/less wear and tear. JDM I would have to use 93 octane correct? As opposed to USDM where I can use 87. What do you guys recommend, JDM or USDM?

4.)Transmission: S80 vs Y80. Correct me if I'm wrong but S80 is USDM and Y80 is JDM? So if I get a JDM b18b, it comes with a Y80 tranny. And if I get a USDM b18b it will come with a S80 tranny? Any major differences? I know JDM trannies tend to have short gears, and this is mainly going to be a DD, will see the autoX/drag every now and then.

5.) My shopping list so far:
-HMO complete change over: http://www.hmotorsonline.com/s...30007

-Hasport EFB2 Mount kit with Hydro to Cable conversion: http://hasport.com/shop/produc...id=32

-Hasport EF to B shift linkage: http://hasport.com/shop/produc...id=42

-Hasport EF to B axles, (or teg axles from local junkyard, see question 1): http://hasport.com/shop/produc...d=105

Am I missing anything? What are these for?:
http://hasport.com/shop/produc...d=109
http://hasport.com/shop/produc...d=110

6.) Wiring:
I'm more than likely going to be using Rywire. Do I send my EF harness and the new LS harness to Rywire? Or just one or the other?


-I think that's everything. Any information is appreciated, can't have enough knowledge. Thanks in advance.

Well I swapped an b18a into a 91 hatch and I needed the axles from the 90-93 teg, I also had to change out my hubs,In order for the axles to work I had to take out the dust rings inside the 90-93 teg hubs, if you don't do that the axles will be to long. my hatch was a dx that came with the smaller hubs[different spline] I did use the hasport shift linkage. Is your car multi-point from the factory? If so then you should be able to just plug in right in to the canon plugs[aka shock tower plugs]. if not then you would also need it wired for multi-point, and you would more than likely need to use the ls engine harness. don't know if this helps but hopefully.
