mackncheese Posted September 26, 2015 Share Posted September 26, 2015 I have an agreement to buy a truck subject to inspection and a test drive. If I buy the truck can I pump up the horsepower? It is an 05 granite with a 460 and an 18 sp. I'm not sure if it is an aset or not. Rochester does not show any injectors or turbo kits for asets. I already have a 1999 E7 in an rd 690 and know I will want more power. If I buy the truck I was planning on dropping it off at Antrim but after reading 20 pages of the forum I am not sure if you can modify this engine. Thanks for your time.

Jamkar Posted September 27, 2015 Share Posted September 27, 2015 Good luck mate, wish I new the answer also. I've got a 470 CCRS but ain't game to be a pioneer with upgrades.

johnsmack Posted September 28, 2015 Share Posted September 28, 2015 our local truck shop "upgrades" lots of Cummins and the place they get the kit is working on one for Mack's. It is supposed to have a kit around the first of the year. I have an 05 Vision with the 460 and 18 speed hoping to do the same.

slingblade Posted September 28, 2015 Share Posted September 28, 2015 you should be able to hook it up at mack and turn it up some,they are good motors if the lifters are steel,mack ran some ceramics that diddnt work out too good, Quote Link to comment https://www.bigmacktrucks.com/topic/41956-might-be-buying-05-granite-with-460-can-i-pump-it-up/#findComment-305378 Share on other sites More sharing options...
mackncheese Posted September 28, 2015 Author Share Posted September 28, 2015 Thanks for the replys. I did not buy the truck based on some rust.

wheeler73 Posted September 29, 2015 Share Posted September 29, 2015 The main issue with the ceramic lifters is lack of valve adjustments at the recommended times. The truck mackncheese is looking at has ceramic lifters. Mackncheese only thing I can suggest is for you to go to your local dealer and have them see if the programming is at step 12B. If it is not they can call tech support and have them turn it on and program it. If they tell you they can't tell you if it is at step 12B give me the vin and I will check for you.

mackncheese Posted October 6, 2015 Author Share Posted October 6, 2015 The seller agreed to lower the price some to compensate for the rust. I ran the vin at the Mack dealer and it is an AI engine. Can I put stage 2 injectors and matching turbo in it and the 12B programming (if it doesn't already have it) and have a good pulling truck? Should I have the ceramic lifters replaced or the valves adjusted? The vin is 1M2AG10C75M026820. Thank you all for your time.

bts-4120 Posted October 8, 2015 Share Posted October 8, 2015 if you put injectors you'll do the overhead at the same time see how the valve covers be off anyway Quote Link to comment https://www.bigmacktrucks.com/topic/41956-might-be-buying-05-granite-with-460-can-i-pump-it-up/#findComment-306675 Share on other sites More sharing options...
afrdiesel Posted October 9, 2015 Share Posted October 9, 2015 just do a valve adjustment first before getting into the engine without need, I do recommend to remove the oil pan and inspect main bearings and connecting rod bearings,oil pump and inspect bottom end, that way you'll know the true state of the engine, by seeing it yourself Quote Link to comment https://www.bigmacktrucks.com/topic/41956-might-be-buying-05-granite-with-460-can-i-pump-it-up/#findComment-306697 Share on other sites More sharing options...
