ARCHIVE 2UZ-FE to H55F - Interest?

[cruisermatt]

2UZ is a s*** engine and I don’t understand why anyone would want to spend the time or cost to use one in a swap

Let alone spend the time to make a Toyota ECU that hates you work

but tell us how you feel about 3FE’s?

Don’t you drag that beautiful engine into this!

I honestly don't get the H55 love on here...

Sure, in a SWB 40, anything longer causes rear driveshaft issues but Toyota bolted the 2UZ to H151, why not just roll with that? Especially being a far stronger box than H55 with something making a few horses in front of it

They don’t shift nicely either when compared to a H42. I honestly think NV4500’s shift nicer then an H55f

People want what they can’t have

I've never met an NV4500 or H42 in person but have a H41 in my 40 and had a couple of H55 over the years - a H15# is certainly a heavier shift than a H55, but I don't see the need to reinvent the wheel when Mr Yota makes a bell housing to attach a manual gearbox to a 2UZ.

Same deal with the 1FZ to H55.

Yeah I guess you're right...

The h151, that came behind the 2uz is tough to come by in the states. I am sure that the reason folks have interest in using the h55 behind the 2uz is because they are easier to find here. I would agree that the h151 behind the 2uz would be a better fit.

The 2UZFE stock ECU runs the engine without the auto slush box attached. It will store codes due to missing signals from the transmission, but the engine still runs properly.

It has been a while since I buried my head in this, but if I recall what it won't do is start if it doesn't get the appropriate signal to indicate that the transmission is in park or neutral. The ECU also limits max rpm (to 4000 rpm IIRC) if it is running with the "missing transmission" in neutral or park.

This shouldn't require rocket science, piggyback ECUs or other gadgets to overcome, you should just have to supply the ECU with the appropriate 12v signal for "park/neutral" and "drive" positions etc.

From what I remember there were added complexities with the later 2UZFE VVTi (2007 and up - again IIRC), because of the VVTi, and its electronic chip key. The ECU needs the signal from that key otherwise the ECU won't allow the engine to crank. I don't remember what the complexity was with the VVTi specifically, perhaps there wasn't one, or maybe it was just the immobilizer key/ECU combo, but reading about other 2UZFE swaps I seem to think it made life more difficult.

I made sure that I got the ECU, harness, throttle cable and all bits and pieces I wanted from the guy who was parting out the donor truck.

There have been quite a few 2UZFE swaps done, most using the automatic, but plenty without. These guys are doing 1UZ/2UZ swaps in manual transmission 4Runners and other Toyotas. They have on the shelf parts to do these conversions, motor mounts, transmission adapter plates etc. but nothing specific to Cruisers unfortunately...

Depending on the particular tranny code, doesn't the stock ECU limits the engine performance?

I think this would solve the issues with the Trans signals.

I am not aware that the Tundra came with a 4.7 manual transmission in the US. The first gen tundras with a v6 did come with a manual but that is not the same. I would be cautious if you buy that ecu hoping that it will run an 2uz with a manual as it is.

I think the appeal to the H55 is we can still by it brand new in the USA and it bolts up nicely to the 2f and 3fe engines.
