Will these newer engines give good fuel mileage? Do you think up to 30 mpg?LiftedAWDAstro wrote:Yeah...stick with a gas engine! If you want it to be quiet and shake free, a Cummins 4BT or any older style low pressure injection system won't provide this. If you want power, torque, quiet and smooth you will need to look at the new common rail high pressure injection diesels.

i expressly joined this forum to research for an astro diesel swap
i only have started but im fairly sure the best engine would be the 4bd1t from the isuzu npr
less vibration than the 4bt
they go for for as cheap as 1400 as much as 4
they do good in fullsize gm trucks
this guys results http://www.isuzudieselswapper.com/index.html
MPG test results are as follows: (1) 200 miles of in town driving produced 24 MPG....(2) 200 miles of interstate driving at 60 - 65 mph produced 32 MPG
the auto tranny in the astro is the 700r4 correct? he sells adaptors
271tq peak @ 1800 rpm
128 hp @ 3400 rpm
i think if you turn up the ip and add an intercooler and ,more boost maybee 200-220 hp 350-400tq
this setup in an lifted awd>4x4 swap
+1 on the shitty salt filled streets in ny im from rochester too
having problems finding a astro in my price range with rot
There is no vacuum on a turbo diesel so you would probably want to run a Hydrovac system or some other system if you wanted power brakes. There is a bit more room under the hood when you use the Hydrovac system so one of the turbo diesels that Isuzu manufactures may fit. I would not hesitate to use almost any diesel engine that would fit (there are a couple designs that I would not use).Someone wrote:the problem with most of the Isuzu motors is that the Turbo is usually on the drivers side, and will not fit because of the brake booster... It could be modded but would be alot of work... but a Hino 3.4L Turbo Diesel would fit like a glove... but I can not put a toyota motor in a chevy anymore than putting a chevy motor in a Toyota... just does not seem kosher
