springersrolla Posted February 23, 2009 Report Posted February 23, 2009 hey guys i gotta pull the 3k out of the car cause its blowing smoke, and using too much oil. I have a 4k out of a ke70, complete. And the 3k in the car, complete. I'm gonna rebuild the bottom end of the 4k, with new pistons,bearings, rings, bore and hone, get a balance, regrind cam and face lifters. I found a 3k at the wreckers with no timing case,just head and bottom end, i was thinking of getting the head and putting it on the 4k, or just use the one in the car now, or is it just worth getting the 4k decked, i can do everything i need to the 4k motor out the car, and put it in with ease. i guess main question is, can i get the 4k head decked to 3k head specs(Compression ratio) or should i use the 3k head? id prefer to have everything built and ready to just drop in, so the car isnt off the road for too long.

toyota_ae71 Posted February 23, 2009 Report Posted February 23, 2009 (edited) hey, Go the 4k head, shaved and what not. Better rocker gear, and bigger valves (i think) + the 4k isn't as old as the 3k so water galleries shouldn't be as corroded, thats if its a low kay 4k. And yes you could get it decked/shaved to the 3k specs. But miaswell go a lil more :hmm: Edited February 23, 2009 by toyota_ae71 Quote
