hours - 10,500 03-09-2013 12:38:33 75.92.244.100 Report to Moderator	Re: 1988 Case 7120 - excessive blow by in reply to njfarmer, 03-08-2013 16:29:06   Well, it sounds like a fella would have to count on buying the cylinder kit, and maybe some injectors. 10,500 is alot of hours. [Reply]  [No Email]

Head shop guy told me the engine is in great shape and just needs valves reset, did that. Sent injectors in for a rebuild (to a performance shop) got a little bit of a power boost on them, added fuel and a better set of wheels on the turbo. Next I bent the shaft on the 250 hp pto dyno and before I was pushing ~180-190hp. These tractors can do some serious work when built right but are a solid work horse out of the box. I dont recommend adding alot of fuel with out a better flowing turbo for lower egt's. My egt's are actually slightly lower that before the valve job and 180-190hp dyno. I have mechanical gauges for EGT, boost, oil pres, coolant temp, oil temp, and fuel pressure (very informative, the bar gauges are junk imo) [Reply]  [No Email]

And yeah, I have read that though advertised as 150 at the drawbar, people often say they put their 7120 on a dyno and see them commonly much above 150. [Reply]  [No Email]
