1FZ-FE Thoughts/Clarification (6 Viewers)

[midknightc3]

I plan to try it with H55 first, as my Qatari friend did for his swap, then go with H151 if needed.
When I reached my Qatari friend, he shared this photo, which is an FZJ80 bell housing that had been modified to fit the H55 pattern.

So is that a factory 1FZ-FE to H151 bell housing that was drilled at tapped to accept the H55F? Doing this, does the H55 shifter match up to the factory holes in the transmission hump of an FJ60? The bell housing conundrum is my single biggest hangup in doing this swap. What about the input shaft from 1FZ to H55, are they the same?

I am currently planning to run with the Haltech kit for the ECM as I am considering a supercharger in the future, though not entirely sold on that idea.

yes it is an h151 housing that has been filed then drilled to match h55 position. the guy wanted to keep the h55 position on the car so he keeps the shifter the same position.

The input shaft I'm positive it is the same.

if you want the faster way, just keep it with h151

I would probably swap in the gm straight 6 rather than the 1fz. Then you get vvt and easier flexibility tuning wise as they use the LS motor ECU.

The GM Atlas inline six is an impressive little guy. I personally think there's a stigma around them that they're just a junky Trailblazer engine. People don't realize how advanced/impressive those engines were.

If I wanted to swap an inline six gas engine into something it would be the 4.2 Atlas.

I view it as a great option if you want to retain the i6 motor feel that the cruisers all had rather than v8 but get a pretty good power boost. Being that they were in front of a 4l60e gives you pretty much any transfer case option you want. 300hp and a very long flat 300 torque curve would make a nice driving cruiser.
