    Builds Cummins R2.8 in 2nd gen 4Runner

    Picked it up out of southern KY, not sure where it came from before that. It definitely took some cleanup and repainting to hide some rust spots, but the original engine leaked every kind of oil imaginable so that really helped the front half of the frame stay pretty rust free :rofl:

    Nope, the section of the pan that was removed was back from the oil pickup, so didn't have to modify it at all. However, the oil drain plug did disappear so the not-used oil heater plug is now the drain

    The R2.8 is a variant of the ISF2.8 used overseas yes, but is not identical to other products in hardware or calibration. It uses the same base engine as the ISF2.8, but has a custom shop order unique to the crate engine, and the calibration was also specifically developed and tested for the...

    We happened upon an intercooler that's used with the variant of the 2.8 engine that is used overseas, but finding something of similar size should yield a similar result. No damper or any vibration reduction other than getting pretty lucky with engine mount geometry :)

    If I could choose, I would target highway cruising speed somewhere between 2200 - 2400 rpm. We've got a couple test vehicles that run in those ranges and the engines are a lot happier. Fuel economy is better and engine temps stay cooler in the vehicle that runs a steady 2200 rpm and it has some...

    Sorry, have been MIA for a while. No major updates, both my husband and I have been using the 4runner as a daily driver and love it. Still getting mid-20's for fuel economy and no issues or complaints. We've got a fuel leak at the pickup out of the tank and my fuel gauge on the dash isn't...

    If you've got an '85 pickup, have you seen this repower? https://www.cummins.com/news/2017/10/20/repower-profile-tav-toyota-xtra-cab http://www.fourwheeler.com/features/1709-1985-toyota-pickup-diesel-mcfly/

    The 4.10's offer awesome peppiness around town, but yeah on the highway I'm up around 2700 rpm at 75 mph. So not the best, but hasn't seemed to hurt fuel economy too badly. I got ~26 mpg on it's maiden voyage and I'm tracking this next tank now that I'm back on my daily commute to see how it...

    Build is finally completed! We had a big push over the 4th of July weekend and the following week to get everything done so we could take the 4runner on Cummins Cruise 2019. Everything got put back together for the final time and we took it on a 10 minute test drive Tuesday night around midnight...

    The parent engine of the R2.8 is the ISF2.8. The shop order was hand selected by our team to combine the appropriate options for the US market. We have manufacturing plants for that platform in China and Brazil. Once the base engine arrives in the US, it is upfit with the crate specific...

    Sorry for the long delay, progress has been minimal the last couple of months but we've started to pick this project back up again in an attempt to make it on Cummins Cruise 2019 in July. Finishing up final touches with the body off - exhaust fabricated, painted, wrapped, and installed...

    Builds Cummins R2.8 in 2nd gen 4Runner

    Sorry, its only 2" back not three. But basically the engine is as far forward as it can be to still allow room for a mechanical fan and cooling package. That plus this engine's flywheel housing coupled with the bellhousing on the transmission adds enough length that it all mounts farther back...

    Slowly but surely making progress. The engine has been put back together with the final transmission adapter/flywheel/clutch (the last one was just a mock up) and the drivetrain has been mounted in the chassis for the final time. Driveshaft has been shortened to accommodate for moving the...

    I used Axis's engine mounts and although it was kind of hard to tell because I couldn't get the engine in far enough, it appeared that they were pretty close to mounting up to the frame side mounts. I think it somewhat depends on your transmission adapter and transmission and where that needs to...

    Cummins r2.8 into 1990 Toyota 4Runner

    I'm doing an R2.8 swap into my 2nd gen 4runner and keeping IFS. You can check out my build thread here: Builds - Cummins R2.8 in 2nd gen 4Runner It is a tight squeeze, and required a 1" Diff Drop front and rear, 1" body lift, and a modified aluminum oil pan. So not impossible, but not super...

    With the wedding and Cummins Repower Cruise over with, finally making progress on the 4runner! New goal is to have it completed for Overland Expo East, so if anyone will be in the Asheville area in November, come check it out. Planning on taking another inch out of the rear by swapping out...

    Trying to stick with IFS if I can for now, might come down to swapping to solid due to engine fitment reasons anyways, but we'll see how that goes.

    Slowly making progress. Stripped off all the old suspension, cleaned and painted the frame, replaced all the bushings, and re-installed suspension components. New control arms (coming soon), coil springs, and a new third member to change RAR from 4.56 to 4.10 I also got my two...
