Hey guys i have a 3sfe engine that only has 94,000 miles on it and i have a 3sge with a rod knock. So I was wondering if they would bolt together without any modification?

Hey as far as the specs on the two engines are concerned, the twincam head on the 3SGE, is really the only major difference. But you might want to check with Jeremy as far as what other differences, might interfere with making this switch. What looks simple on paper, might be more work than it's worth, then again you might just be on to something. racer  |

I thought that I remember hearing that it was one hole on the blocks that didn't match up. It could probably be done with little modification. I would ask Jeremy first though, as I *think* he's done this one before.

I would ask Jeremy first though, as I *think* he's done this one before. The blocks will mate to any head but lacks the pulley support for dual individual cams. Better off using a 5SFE head which Jeremy has done before. 5SFE has a higher compression. But I prefer 3sfe for lower compression so u can add more a/f mixtures. Then again - thats another subject.  |

it has nothing to do with the pulleys or any holes.
The major difference is the valve releifs in the pistons
in a FE the piston has 22.3 degree cuts for the valve releifs a GE has 50 degree valve releifs. if your timing belt breaks you bend a valve or if someone installs your timing belt incorrectly you will bend a valve.
if you were to take the GE head & the GE pistons, and get new rings & put it in the FE block it would be fine.
You could even be fine if you just bolted the head on & made sure your cam timing was dead on. & make sure you replace your timingbelt tensioner & change your t-belt at regular intervals to make sure you don't break it.
but it's still a risk.
