i think this is a good idea, but in order to protect the sanctity of the info there needs to be a rule that only people who have performed a specific swap first hand (not " i had a buddy......." or "a guy online posted.....") can provide the info
if there is one thing that i have found is that bad info on forums gets passed around because it sounds believable, and is usually mixed in with good true info. but only a person who has actually done the swap could sort it all out.
a good example is everybody on the forum go through your last 10 posts, on how many of those 10 posts did you post something that you yourself had not experienced first-hand in real-life?
HERE IS A PRIME EXAMPLE OF WHY:
i was swapping an engine on a 1998 isuzo rodeo this past weekend, i was putting an engine from an auto trans rodeo into a man trans rodeo ( the holland listed several years interchanging). the holland interchange, and the isuzu forums both said that they are a direct interchange.
but i found that the auto trans crankshaft doesn't have a hole big enough for the pilot bearing, and the hole it does have was too small for a bushing, (it was 3mm larger than the input shaft) so i had to have a bushing that fit the inside of the input shaft (ended up coming from a much older model) lathed down to 1.5mm wall diameter to make it work because the computers only listed the 50mm or so wide bearing for that model/year. then after installing the engine the bellhousing woud not fully seat (about 4mm spacing) it turns out that the auto and manual trans have the dowel pins in different places, so i had to pull it al out, pull the pins, (lots of heat and a slide hammer) and put it back in. then the dummy water pump that the fan and pulley bolts to is 1" further to the driver's side. so the fan now hit the shroud, so i needed the dummy-pump from the other motor, that the guy i was helping already took back to the wrecking yard to get his core charge back.
i know that was really long-winded but there will be no point in having all of this collaberated info if some of it is bad and no one will be able to know it until they go through hell figuring it out, "but the interchange chart on trs said it was a direct swap......" if i had only known i would have told him to find an engine from the same year, with man trans, as opposed to letting the j/y (using holland) say "yep....this'll git'r done"
