Anyone Considering a Cummins R2.8 w/ HF55 Swap?

[gregnash]

You'll end up wasting too much money on the 3RZ and modding it to the point where it wouldn't be reliable. I own a 3RZ Toyota, and love (and praise) the little engine, but I don't think it'd do very well in an 80.

Supercharging the 1FZ doesn't really do much (we also have a TRD SC'd 80), and gas is an issue. I've always wondered why there arent any 2UZ swapped 80s in the states? (fuel efficiency no object)

I'd love a diesel LC, for no other reason than it'd be plain cool, but I'm too much of a purist to swap anything other than a Toyota engine. So, If it were up to me, I'd slap a turbo 1HZ engine and be done with it. Although it'd probably still be slow, but I don't care, there's no such thing as a fast cruiser lol

Think I remember reading that the main issue on this swap is the security around the ECU/ECM/PCM being able to hack the system to allow it to function properly in any vehicle. I know that at one point Jason (@reevesci) was working on something with the 2UZ and there are a few guys out there that have done them but I am assuming it probably takes some very specialized hacks to get it functioning properly. Hence more $$$$$ on the swap when you can reasonably get a 5.3 Vortec in for $10-$20k.

No way would mileage be anywhere near 20. I have a 2003 regular cab Taco with the 3RZ manual trans and the best I've ever done is 22 MPG. Week in week out it's 19-20. Add a supercharger and another 1500 lbs and you'd be right in the LC MPG range where you started.

I agree. I've got an 2004 and I've got 24mpg in it. Add power and weight and it will drop.

Yeah our 2011 4Runner gets pretty s***ty mileage. Really think that the EPA needs to re-evaluate their measuring standards because the sticker says 18-22mpg and we AVERAGE 17.3mpg with a mixture of city/hwy. Even with an entire tank on the highway, keeping it around 70-75mph we are lucky if we get 18mpg. Best every was 21mpg and that was going mostly downhill (8k' to sea level) keeping it between 65-70mph the entire way over about 300miles.

The EPA needs to re-evaluate a lot of things imo!

We just finished our first conversion into an fj62. We templated everything so we have a complete conversion kit for any 60 series with a manual trans. We installed it with an h55f and so far this thing is amazing to drive. Not only quiet but powerful, and fuel mileage will be reported when I actually run out of my first tank

Drool.

Would love one of those 2.8s. I love my 4BT to pieces, but the 2.8 should appeal to a much, much wider audience.

The 4BT is a great engine, but IMHO not a great fit for a cruiser. We've done a 4HK and it was OK, but still really unrefined. I think Cummins is coming to the market with a great solution for the cruiser, especially when the pricing will equal the LS EROD engines.

Nice going. I want!

Is there video or a build thread on this project? I'd love to see one in a 40

what is the advantage over the QSB b3.3t? I have the mechanical version and have heard the QSB electronic version is even more efficient.
The 3.3 seems relatively easy to come by and is cheap? mine was 5k new as a crate motor

I just saw this thread. I have a FJ60 with a completed R2.8 conversion. It's awesome in every aspect. Smooth and quiet. My setup is a 1987 FJ60, H55f, 35" BFG KM2s, 4.56 gears. I'll be switching my gears out to 4.11. I can easily cruise 75+ mph. Tons of torque and currently getting 20+ mpg. There's a lot of 2.8 naysayers out there but fortunately, I can't hear them over the sweet whistle of my turbo.

Who did the conversion? Are you riding on an 80 chassis or stock with a lift?

Overland Cruisers in Bozeman, MT did the conversion. No need for a 80 chassis. It's on the original 60 frame and suspension. Suspension is sprung over. You can see pictures/video at Torva Expedition & Offroad (@torvaoverland) • Instagram photos and videos and Overland Cruisers LLC (@overlandcruisersmt) • Instagram photos and videos. I'll try to post images and videos when I get home but it'll probably be a couple of days.

I'll post better pics later. I don't have access to my files right now.

Size looks to be similar to the HX-30 turbo. I’m running the same X2 power battery. Great looking setup. What size exhaust is that off the motor? Looks like it reduces down to 2”.

Looks and sounds fantastic. More importantly I had no idea there was a specialty cruiser shop in Montana. I can now add it in to the list of places for the "where can or cannot we move to next with "

I'm thrilled by the amount of space there !
