Cummins 2.8 actually in an 80

I can guarantee you the 1FZ is a stouter motor than the Barra.... Yes I am prepared for all the internet fighting.

Agree with this. I also think a 2J is stouter than a barra but that's a different discussion. (And before the flaming starts, I regularly drive a Ford XR6t with a worked barra.) Turbo 1FZ is better than Turbo Barra in an 80

I think for certain folks (depending upon where you live) the Barra could be a contender. IMO...this fella gives some honest and balanced information comparing the Barra and the 2J.



I don't think we have enough data or real world experience with turbo'd 1FZ's yet to make fair comparisons. And 'better' of course, depends on the intended use, cost and doesn't factor in what is 'plenty good enough'. No doubt both engines have strong points...exceeding that of the other.

Time to move this discussion some where else. It has nothing to do with the Cummins 2.8. But I have heard this video before, still not buying the Barra is an upgrade.

The positives in the video for the Barra vs the 2JZ are:
- Larger displacement - Still smaller than 1FZ
- VVT - Not an option on 1FZ.

Negatives:
- Oil pump - 1FZ has built in oil pump
- Relatively weak bottom end - 1FZ Bulletproof bottom end
- Small aftermarket - Same as 1FZ
- Large size - Similar to the 1FZ

Safari started turboing the FZ here in about 1996, mine was done in 1997 and had done close to 100,000 km with the turbo, a lot towing, so I think that indicates they take well to boost.

Any Dyno figures (HP, Torque) for comparison?

I'll see if I can find them but pretty similar to what @NLXTACY kit makes. Safari had a front mount air to air intercooler, but intercooler doesn't add power as such, it prevents power loss due to lower air density caused by heat

it is not, we actually haven't really had ANY demand for it so it's on a "as needed" basis. email info@deltavs.com to discuss.

Drivability is hindered only by the engine and the EGR system. You can unplug the EGR (and live with a constant "check engine" light that locks out the diagnostic gauge) for better drivability, but that is obviously not recommended. The transmission works quite well with it though! On the Cummins Cruise around the northwest in 2018, got ~26-28 mpg at 80 mph on the freeway with General X3 35" tires and stock gears (and that is with non-stock injectors too for a little extra oomph).

"Drivability is hindered only by the engine and the EGR system." Curious--do you mean by that that it lacks power?

I’ll have to go back and reword that a little. I mean by the tuning of the engine to deal with EGR.
