I have a 1990 4Runner that I have 3.4 Swapped with a motor from a 1999 4Runner, Straight axle swapped with a 1985 axle, and leaf spring swapped the rear with chevy 63"s. Low maintenance flexy setup.
I'm considering selling because there is coolant in the exhaust, and my living situation does not grant me a place to do the work, and the money isn't there to pay someone to find out I need a new motor. I may hang onto it until I find better times, unless I get a decent offer for it. The front axle (4.10) needs to be geared to match the rear (4.56), both axles are stock. So basically the major hangups are head gasket/new motor, and regear of the front axle for a solid rig. hit me up if you want pics or have any questions. May be interested in a trade
