Hello, newly registered on the site. I have a 76 Dodge Ramcharger that I am starting a 4BD2T swap and after reading through a fair number of posts hadn't seen any mention of the possibility of using a P7100 ip. Any thoughts?

The A size pump on the 4bd has a 17mm or 20mm taper on the shaft. A p7100 has a 30 mm taper. It will not just slip on unfortunately. Then you would have to address the different mounting flange patterns and pilot sizes. If it was easy it would probably be done more often. Anything is doable if you have the capability and/or money.Hello Dougal, I am no expert but if they are both right rotation pumps does it matter what side they are on? I'm sure it is much cheaper to go with a p7100, if it would work, than trying to boost the pump on the 4BD's. I mean a 12mm P7100 is readily available and you can go past that, though i can't imagine a 4BD would need more. I have read a fair amount of Randy's stuff and I think he was easily in $5000.00+ on the pump. Anyway I thought perhaps some brave soul might have tried to swap one in. I wish I had access to one just to see if the Isuzu gear would slide right on. And again, I am no expert so I was thinking if they are both right rotation it doesn't matter which side the pump is on.
Cool. Any pictures? How does it run?Mine came with a p pump! Completely rebuilt with 6BTA turbo and billet compressor
Thanks for the information. I would guess that unless you can swap the cams out the taper is going to require a machine shop and a fair amount of money right there. The flange seems like it shouldn't be tough. I see the 4bt pump gear is straight cut and the 4bd gears are helical so no way I can see to simply swap pump plus gear, if the gears were even the same size.The A size pump on the 4bd has a 17mm or 20mm taper on the shaft.
