I am rebuilding a Dexta and plan to put the larger 152 CU pistons in. The super Dexta also had a RPM increase in addition to the larger Cubic inches. Can I adjust the injectors to get the proper increase in HP and how do I do this

thanks a million

Seriously though, I dismantled my oil bath and got rid of it completly. I installed a flexible 3" piping from the intake to a conical K&N air filter where th old oil bath used to be. Instant throttle response, no oil bath, easily cleaned, and noticable increase in raw power. This is all on a 62 FSM that is, but im sure itd work on a Dexta. My father in law was skeptical until he drove my FSM and was impressed, so much so that he says he will soon be converting his 1991 Zetor 8211 to the same filter I have. LOL

I rebuilt my 1959 and like many before upgraded from 144 to 152. The Pneumatic govenor will be the culprit that precludes more power and RPM. The oil bath air filter is also a factor. When I feel mine pulling down too early, I service the air filter and get my power back. Mine backs off power above 1650. From there to max no-load, it will rev, but won"t hold the pull. OK to me, don"t need it. Everything below 1650, it will grunt till the tires spin or something breaks.
Bottom line: I rarely need to work mine above 1500. good luck with your quest for more power and pass any insights on to all.

Buy a belt driven centrifugal supercharger and bolt that on, then increase the fuel rate. Also, port and polish the head, buy bigger valves, K&N air filter, and straight pipe it.... wait... Im dreaming, I must be crazy...lol Just kidding man, Im bored and its near midnight. But it could work!!!

There are more changes than just setting injectors between the Super and the Dexta engines. The Super has a different injection pump and air cleaner.

I would not recommend adjustments to diesel fuel components without the proper equipment.
