I've got an 85 si that the original engine with its early efi has 250,000 some odd miles on it and is getting tired. It's developed an oil leak in the main seal as well as the seal at the distributor and head/block. It's getting increasingly hard to find parts for this engine and have decided that rather than continuing to spending money on unobtanium that it is supposed to be relatively straght forward to put a new k-series engine in it. Not only is it not 40 years old but there are several models over more than a decade that have the k-series engine making it far easier to get parts as well as a huge aftermarket that supports this engine. Through general research I've learned there are several versions and setups of the k-series and have come to the conclusion that what I should go for and have my eyes on is a k24a rbb dohc iv-tech out of an 03-14 Acura tsx with a 6 speed manual transmission. I wouldn't go so far as to clam to be a mechanic but I'm no stranger to tools and have done most all the work on all of my cars as well as many of my friends cars. But I've never done a whole engine swap before and especially not by myself. I suppose my question would be does anyone have any advice or things to pay particular attention to for me to do this correctly? I'm I correct in the type engine to get and go ahead and pull the trigger and get it? What all am I going to have to get to pull this off? And is there anyone that may be willing to assist or guidance to help me avoid unnecessary mistakes or over spending here in CO I'm actually in Longmont/Boulder area?
