4JH1, Bosch P7100 pump conversion adaptor

Isuzu 4JH1 Adaptor plate and hub to suit P7100 pump.

Do you want ALL the fuel? Are you into drag racing or just generally want to push the limits or the break things? Want a nasty lope idle? Then you want a P7100 pump conversion!

This adaptor plate will allow the P7100 pump to be fitted to a factory 4JH1 timing gear case and pump gear. Please note: this is not a basic pump swap and will need custom pump setup, injectors and lines to suit and requires some modification of components for clearance, starter motor requires re-clocking etc. it is also well outside the design limits of the engine.

kits can also be made to suit 4JB1, 4JG2 timing gear sets on request, but 4JH1 timing sets are the best suited and more robust.
