Sure the cost of the swap might be a few thousand, but you can pick up complete running driving functioning J30 6th gens all day long for less than a thousand bucks. At least around here.
I picked up Connie (J30A1 02 Coupe) for $600 with a blown head gasket, paid $400 for a low mileage JDM J30A from an Odyssey, dumped it in and off I went. Easy peasy. Around $1000 to get her on the road and she's given me over 300k reliable km in the past 4 years.
I picked up Midnight (J30A1 00 Coupe) for $800. Had to put in a gas tank, a power steering line, and 2 wheel bearings (that were harvested from a 2000 V6 coupe I bought for $200 for parts). And now she's on the road running almost perfectly for around a thousand bucks, too.
I even picked up a 98 J30A1 sedan (with a new transmission and strong engine) for $400 a few weeks back, as a parts car. If I wanted another car on the road, I could put a gas tank, brakes and a hood latch on that one and have it on the road for around $1000, too.
So just sell yours and use the money to buy one with the J30.
Don't make this harder than it needs to be!
