I posted this on hondahookup and got no responses, so I want to see if I fair better here: I ordered a h22a with lsd from jdmsource.ca today. They seem to have a good rep online and were really nice to talk to. They say they'll be e-mailing me pics before they ship it (not sure what that accomplishes, but it's a nice gesture). I have a friend of a friend that's going to do the install for $300, not including the wiring, which I'd rather do myself (I'm good with electronics - figure it can't be that much worse than modding an 1.6 xbox). So here's my NEW set of questions: 1) the physical install should be no problem for this mechanic guy. Engine mounts are the same, no space issues right? It's going from a USDM 97 sh-type (h22a4 engine and m2u4 tranny w/ATTS) to a JDM h22a with m2b4 (w/lsd). 2) The wiring shouldn't be too bad (OBDII p5p to OBDI p13) using this link http://www.preludeonline.com/showthread.php?t=74554 as a guide. Any pitfalls I should avoid, specifically anything that has to be done BEFORE the engine goes in the car? 3) I think I'll need to rewire the distributor. I can't find the link right now, but I need to move the CKP and TDC wires from where they were at the crank of the h22a4 to the distributor of the h22a, I think (I'll be using the JDM distributor and injectors). Any other wires that need moving? 4) What about axles? I don't think the new motor is shipping with axles, and my old ones are kind of going anyhow. I am really lost on what axles to get. I know what kind to get if it was going into a 96 accord, but I don't think that'll help. I also know that the axles are different from a sh-type to non sh-type prelude, so I imagine that they're different from a JDM w/lsd. Thanks for the response, if anyone does. I am having trouble finding any info on this type of install. Must be that sh-type preludes stay sh-type preludes? Either that or maybe the install is so easy no one bothers writing about it, in which case I'm worrying about nothing.
