I 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. The 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? I assume I would have to use 93 octane with the JDM motor 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://hmotorsonline.com/shop/sc2000search.cgi?what=page&item=30007 -Hasport EFB2 Mount kit with Hydro to Cable conversion: Hasport Performance Online Store -Hasport EF to B shift linkage: Hasport Performance Online Store -Hasport EF to B axles, (or teg axles from local junkyard, see question 1): Hasport Performance Online Store Am I missing anything? What are these for?: Hasport Performance Online Store Hasport Performance Online Store 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.
