Miller85 Posted September 7, 2016 Share Posted September 7, 2016 I had a driver put a rod through the block on my Etech 460. I have in the barn a E7 Etech 300 that came out of a garbage truck. I know I have to pull the cam and reset the timing but I'm just looking to get the truck back on the road with the engine I have. My question is what is the highest HP that I can bump the 300 to without having to change turbo, injectors, and cam just by getting the ECM reprogrammed? Also where can I get the ECM reprogrammed and how much without having to go through Mack? Thanks C.

880joe Posted September 7, 2016 Share Posted September 7, 2016 I think you could go to a 355/380 they have the same torque as the 427 then get some upgraded injectors and run your 460 turbo that should be a pretty good running motor then Quote Quote Link to comment https://www.bigmacktrucks.com/topic/46737-mack-etech-300-hp-upgrade/#findComment-344911 Share on other sites More sharing options...
Miller85 Posted September 7, 2016 Author Share Posted September 7, 2016 Do you know where I could get the ECM reprogrammed besides Mack and how much it would cost?

880joe Posted September 7, 2016 Share Posted September 7, 2016 I have been getting my injectors from K&S Diesel out of Schofield WI 800 535 0172 they were around 90 dollars a piece exchange last set I bought, Call and talk to Jason i think they are making 50,75,and 100hp injectors. I also got a set from Antrim Diesel i think they were about 105 each Quote Link to comment https://www.bigmacktrucks.com/topic/46737-mack-etech-300-hp-upgrade/#findComment-344950 Share on other sites More sharing options...
Mackpro Posted September 7, 2016 Share Posted September 7, 2016 Make sure both engines are the either ETECH's or CCRS ( 2002-2003). Use the turbo and injectors and engine ECM off the 460 ( of course off-set key way if ETECH). Rest of the engine is the same regardless of HP. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/46737-mack-etech-300-hp-upgrade/#findComment-344960 Share on other sites More sharing options...
