hey man, this threat is fine b/c it goes through like everything to do with the b18a swap, so i suggest reading it through if u have some time, also now u have 2 experts me and crxfreak who just did swaps so we can be alot of help, anyway down to ur questions, yes ur lucky ur Hf is the best car to do it in, the harness will work b/c u have mpfi, but sadly ur hubs wont, go buy some DX or Si hubs at a local wrecker even before u start. when u use ur stock HF harness use the LS injectors. OOO i see heres your question about hubs, umm ya, integra hubs... u can go for it, no real reason tho, Si/DX ones will work find, just use those it will make ur life easier. for axels, use the stock integra axels and intermediate, theres a link on the original post a few back about how to take the spacer out of the axels so the tires spin, make sure u read that. next question about the resistor box, i have no idea man, i used a CRX Si, and it worked fine, but ur HF might be different hopefully someone else can help u out there. Lastly the ECU deal, i got my ECU from a wrecker for $50 bucks canadian, the auto wont be as good, dont worry about pins, just go buy an old 5 speed ecu, trying to rework an ECU is hard and sucks up alot of time, just do it right the 1st time so u dont have any problems. anymore problems man let me know.
