Jamied625 Posted October 2, 2012 Share Posted October 2, 2012 I would say it might bolt up but the 237 probaly has a bigger pump being a turbo motor needing more fuel. That is just what my thought is though i could be wrong.

DodgeMan Posted October 2, 2012 Author Share Posted October 2, 2012 I planed on turboing the LJ and the B81. Just didnt know if it was a good idea to use this pump. I dont want to drop the crank out and onto the ground. Only thing i found so far is the timing is 28 BTD instead of 23 BTD Quote Link to comment https://www.bigmacktrucks.com/topic/27603-injection-pump/#findComment-139965 Share on other sites More sharing options...
Jamied625 Posted October 2, 2012 Share Posted October 2, 2012 you may have to run a different injector too especially if you are going to put a turbo on the truck i would think Quote Link to comment https://www.bigmacktrucks.com/topic/27603-injection-pump/#findComment-139972 Share on other sites More sharing options...
terry Posted October 2, 2012 Share Posted October 2, 2012 Are the injector lines the same? Quote Link to comment https://www.bigmacktrucks.com/topic/27603-injection-pump/#findComment-140014 Share on other sites More sharing options...
skip Posted October 4, 2012 Share Posted October 4, 2012 The pump will bolt straight up and all the injector lines are the same. Some of the later 237s had the bakelite coupling with the roll pin between 2 teeth and the early ones had the steel plate with 2 cut outs opposing eachother like an old V8 one. So you may have to change that over. Then as mentioned above just time it to suit the horsepower you want. For the power it will be putting out I cant see you doing any damage. I got an old MBR going a few years back and the engine I put in was a coolpower without the intercooler. It blew a bit of smoke when you got stuck into it but its was ok, It was just a farmer doing a bit of gravel work, the old engine is still going strong. Good luck with it Quote Link to comment https://www.bigmacktrucks.com/topic/27603-injection-pump/#findComment-140348 Share on other sites More sharing options...
