View Full Version : 85 Runner

I picked up a clean and almost 100% rust free 4Runner. Looking to build it up, and have it orientated towards a family type wheeler, so nothing too wild. But here's my problem. I have so many directions I could go, and I really can't make up my mind.

The engine is toast, and it has an automatic in it. The axles aren't original, and have 3.90's in them. But its clean, and it was free.

Been toying with the idea of rebuilding the stock engine with an LC Engineering stroker kit, and finding an auto from a turbo'd truck to put behind it, along with a doubler.

Or, toss the 4.3 and 700R4 in it, and rob the 203/205 doubler setup from the big yota since I am scrapping that part of it anyways, and stuff it in the runner. The 4.3 is on propane, and runs great, but its got a lot of miles on it.

I have a set of built toy diffs sitting here, that need some minor upgrades, stuffed with V6 3rds and 4.56 gears. Gonna go to spools front and rear, hy assist steering, x-over and hy steer, and looking at 37 to 38.5" boggers.

I have the truck mostly stripped, and plan on bobbing and boat-tailing the rear, and doving the front. Pulling everything out of it, including the intact harness, dash, and all that crap, and start from scratch.

No idea as to the suspension, but I would like to keep the front leaf sprung. It would be nice to move the front spring hanger ahead about 6", but I'm not sure how the added stress will affect the frame.

Possibly looking at a 4 link in the rear, a transverse one link, or may saty with leafs, though I don't like that idea.

Any input would be much appreciated.

A couple pics.

looks pretty clean lots of work ahead of you but myself would go 4 link especially when your that far into it keep us posted

stick in a chevy 4.3 and call 'er done[cheers]

would probably be a hell of a lot cheaper than rebuilding the 22R, and at the end of the day you still have a 22R to turn 37's

just my $.02

i would go with the four link. i have 6inch skyjackers in mine and i hate it. i want the 4link in my truck now. trail gear sells a 4 link kit . check out there site if you already havn't . saving up for it myself with big coil over shocks its pretty sweet

dont go with the 4.3 its a shitty motor,you'd be better off trying to find a buick 3.8 way better motor with more power,im in the middle of building my 89 runner up ,but yours looks pretty good so far keep up the good work[cheers]

I'm gonna stay leaf up front, I think. Not sure yet, but definitely linked in the rear. 4,3,1, who knows. I got a set of 4 King C/O's, but out here its mostly mud, and I really don't want to be rebuilding them all the time, so I put them on the auction block last week. No takers yet dammit, lol. Sell them and i can get the Atlas 4sp for the other Toy. Anyways, I got a set of F150 coils and some generic Rancho's that will work for awhile, at least to test it out, and see where that leads.

As for the 4.3 being junk, I can't say that I agree. I bought a 99 sonoma new, and pulled the motor out of it with 4700 km on the odometer, and rebuilt it with some goodies. It now has 255,000, and if you have ever seen me drive, you'd know they weren't nice miles. Its getting weak now (it will only light them up into 3rd these days), but with the exception of the build up, its never been touched for anything other than an oil change.

I've got 3 others that have served me well, including the one I plan to use. Its sitting around 368,000, runs strong, but with that many miles, and the enviroment I plan to put it into, it could blow first time out.

I also look at the added bonus that most sbc parts are interchangable with the 4.3, therefore a whole lot cheaper than anything I could find for another motor, including a Buick, Ford, etc. And they are almost guaranteed to be on the shelf when I walk into the parts store. But I will look into the engine for sure. Always good to have alternatives.

Kinda stalled on this build. Haven't touched it for a week or so. Gotta get some heat into the shop, and figure out what the heck I am doing. I have 5 rigs on the go, and the only one running actually cratered, and everyone is buggin me to put something together quick. Means I have to rob parts from this build to make it work. Wanna wheel, and we love snow wheelin out here, but its the build season, so I really don't know what to do.
