    are you running a conventional parking brake at the wheels or just the transfer case brake? If so why not just restore the original park brake system vs going with the transfer case brake system?

    The only direct bolt on, out of those choices is the BW 171270. You just need to clock the housing, which can be done in a matter of minutes. You can read up on the 171270 here https://www.4btswaps.com/forum/showthread.php?20261-borg-warner-turbo

    I have had good luck with the borg warner 171270. No adapters required and a bolt on replacement for the H1C. I think it is is a viable alternative to the HE221w

    So a bit of an update... my injection pump started leaking badly a few months ago and the mileage dropped down to around 17.6-17.8mpg consistently. The fuel spray was pretty constant. I recently had the pump rebuilt (with 3200 rpm gov spring) about a month ago. After the rebuild it was put...

    Any update on your turbo swap? I have been running this turbo for 6 months and initially I had some issues with high EGT's and low boost; but that was my fault. I am really liking this turbo, boost comes on linear and smooth with very little lag. I was thinking that I would regret not going...

  9. Itsy Bitsy Teeny Weeny Radiator on 4BT?

    General Discussion
    Radiator use a stock one, these engines don't need any additional cooling provisions vs your previous engine. With regards to intercooling...I used a Hino truck intercooler. Core size is about 2x that of my radiator. Easy to find OEM or aftermarket and fits perfectly (with some minor...

    On the new DSL-1E there is a 1/2 rate tach output. Not sure if that would solve your problem http://www.dakotadigital.com/pdf/DSL-1E.pdf
  11. borg warner turbo

    Cummins Tech Section
    Put this turbo on my VE 4bt.. Power is very similar to the worn out H1C it replaced, except the EGT's climb quicker. Same pump settings. I may have a tubing/intercooler leak somewhere as I hear a hiss at 18-2000rpm and can only build to ~15psi.
  12. Why dont I see 4bt's getting better mpg than 6bt's

    General Discussion
    I changed my setup a few months ago, previous to that I was getting low 20's (since 2010 or so). So my records only go back till March with my new setup. Previously I was running a TH400 now running the NV4500. My city is at sea level, mainly flat with a few hills. Odometer is spot on, I...

    Consistently getting 30 mpg mainly city driving ve pump with a fuel pin in a CJ7 3.73 gears NV4500 I put in a massive intercooler (off a Hino truck) and it seems to have improved my mileage quite a bit with the stock h1c

    what are you doing for carpet? I have seen several different types of carpet kits with various backings offered for the CJ's. I am just getting ready to redo my carpet and currently have the jute backed carpet. Was thinking of going with the mass backed kit but not sure if it will have any...
  15. Is it normal for an adapter plate to look like this?

    Transmission, Adapter, Transfercase Discussion
    Ok this is the type of feedback I was looking for.. Thanks for your input. Will just run with it! In hindsight the shop should have probably had a custom adapter made especially considering what they charged for the conversion.

    Transmission, Adapter, Transfercase Discussion
    Thanks for the pictures. It seems like your adapter sits flush with the bellhousing at the bottom interface but has a larger gap by the on the sides. Could it be that my setup was installed mis-aligned? Or is this within the margin of error? I am trying to figure out if I should take it...

    A pic would be great!.. The shop told me that the GM setup would give additional driveshaft length vs a dodge setup.. The original combo was a TH400 behind a 4bt, which I ran for 12 years.

    looks like they used this adapter with the nv4500 behind the 4bt http://www.advanceadapters.com/products/712577--chevy-v8--v6-engine-to-the-1993-95-gm-nv4500-5-speed-adapter-bellhousing-kit/ being that that so many bolts are missing including all the ones on the bottom and that there is...
