How much power can you get from a 4bt?

There are no naturally aspirated B-series engines set up for on-highway use.

While this may be true, we have some yard tugs with 4b engines in 'em that would be fine on the road. Low on power and not really legal, but would work no the less.

I've decided to take my time and look for a 4bt with an in-line injection pump.

Good luck, you're gonna need it.



And be prepared to get you're wallet out if and when you do stumble onto that golden nugget! :--) :--) :--) :--) :--) :--)

We have an APU, and an Ingersol roller at work both of them have p-pump 4bt engines. It'd be nice to sneak one out in the ol' lunchbox.

Just don't forget the governers/power level and other differences between the on road and off-road engines.

I have a 2000 119hp 4BTA VE engine which I plan on tearing down, rebuilding by balanceing the bottom end and . 020" performance pistons. I"m hopeing to squeeze 300hp out of it with a little tweaking.

Who has that Twin Turbo'd 4bt in that gold Jeep that at Muncie last year? I was just F L O O R E D By the sheer beauty of the install. I am sure it's pushin Ponys and twisting reins.

I was just going to post up a link to that Jeep, but I can't seem to find it...



Here's a few other YJ conversions:

I'd think a 4bt could get 66% of the power of a 6bt. So, I'm thinking 300hp from a 4bt, on the upper end. (with a VP pump, more with P7100)



The 4bt should get GREAT mileage. I'd think 30+ is totally expectable in street trim.



From what I understand, a great source of roadgoing 4bts is the Frito-Lay style delivery trucks.

A reputable source told me the rotary pump will wear out fast(like 30,000 miles) when it is cranked up beyond 140 horses. I want long-term reliability, so that sold me on a p-pumped motor, plus I've got some time to shop, so I might as well enjoy the pursuit to its fullest. I understand the p-pumped motors were used in FedEx trucks.

Don,

Sorry, I don't believe that for a second. The VE on a 4BT is the same as a VE for a 6BT, just missing 2 lubes on the pump cam disc and 2 delivery valves. I ran my VE on my 6BT cranking out over twice the power for more than 30,000 miles and it was almost 10 years old when I did it and I have owned the truck since new in 93. I also know many others that have been running the VE cranked for more miles than my old one and still going strong, so that doesn't make sense that a 4cyl VE 4BT can't last past 20-40hp more for 30,000 miles.

Hmmmmm, is this the same brilliant individual that told you that adding an intercooler to a non-intercooled engine will result in burning a hole in a piston (lessee here... ... ... adding a device to make things run COOLER will result in a melted piston... yah-oooooookay)?

 

[Don in Missouri]

No, definitely not the same guy. The guy at the Cummins dealership that advised against adding an intercooler had no imagination at all. Guy #2, the one I trust, worked at the same dealership for many years, but parted ways because he is more interested in doing things his own way.

I have a 4BT in a box truck that has the VE pump and it was turned up before I got it with about 195,000 miles. It now has 285,000 and I turned it up more for a while. ( the guys were trying to see how hot the could get the PYRO, so I turned it WAY down. They were pi**ed and I was happy!!!

The VE is a decent pump. I wish my 02 Cummins pump would last that long!!

This motor is getting tired. It moves 11,000 lbs every day and gets 12-14 mpg.

I love it!!
