Difference between 01 and 02 6.0 motor?

I hope someone can answer my question.  Maybe much hasn't changed and I shouldn't be concerned but,

I have an 02 that was built in early July 01 and has EGR.  I heard later in 01, the 02's were built with different programming, maybe cam, different maf, etc.

My question is, when I start modding the motor, do I get parts for an 01 motor or an 02???  I hate it when GM does this crap!  They did it with the f-bodies in 01 too!!!!!!

Thanks :)

If you plan on going into the motor, when you order a cam, you'll just have to specify that you have an EGR system.  You can get a cam with the same lift and duration, but may have to go with one with a little tighter lober separation since you have an EGR system.  Otherwise, when upgrading from a stock cam, since you're going bigger, there isn't an issue.  I would suggest that you do get a steel billet cam.  If the 6.0L is like the LS1, the stock cam is hollow.

 

FYI, not that much changed between the '00 & '01 F-bodies that constituted any major difference in aftermarket parts.  The major thing was the LS6 intake which can easily be retrofitted onto prior '01 cars.

Thanks man :)

One of the things I heard that changed was the size of the MAF.  If so, then maybe the 02 intake kits wouldn't work on my engine.  I would need to order an 01 intake kit, I guess?

Unless the MAF housing diameter didn't change.

To my knowledge the 6 litres are the same 01 and 02.. A friend of mine just got a 2002 6 litre (feb.2002) and I have been all over it..It has the EGR and everything.. I do know the 01 and 02 5.3s are different.. The 02`s have the EGR deleted..

 

BTW,The maf is also the same diameter..99-2002 is 80mm.. No change yet..

      Great info to have, I printed out what you had in your document as well as Newdudes post as I could see this mistake with the hardware happening very often if not realizing what type of special bolts are being used and just guess on bolt size for torque or the good enough "easy" method as per whack in the used bolts with an impact and send it !.

      Auto start stop disable

      By dennismc · Posted

      I installed the Auto stop eliminator on my 21 Sierra SLT shortly after I got it. They have a detailed video instruction on how, took me about 20-30 minutes to do. I was apprehensive too to start tearing apart a new truck but it was pretty easy install. Like you mentioned get some trim tools. I went to Harbor freight and picked up a set. If you can find some install videos/instructions to give you and idea for a plan of attack you should be fine.

      OCI, not when but why?

      By Chuck FB · Posted

      If all oil manufacturers had to meet a higher standard for not just the initial filtering of the oil but that they had to improve on their formulation so that the oil cleaned the engine such as the Valvoline R&P or the new Mobil product ( assuming it works similar of course ), and the oil was changed on an interval based on good UOA data, there shouldn't be any gremlins running around like miniture rats on top of your heads to be washed down into the oil pan below 😁

      A while back on another thread there were comments and thoughts on air filters and I know that can tend to be a bit of a hot topic because of outfits that have a vested interest in selling aftermarket air boxes fitted with the gauze type of oiled elements touting the lower air restriction. However and unfortunately I don't know where I have seen the test results in the past about the amount of dirt through a test procedure that these style of filters do pass more dirt through than a properly designed ( not some cheap Chinese knock off ) paper/synesthetic media filter can do. Lake Speed had a conversation on that topic with one of the employees at Donaldson and there seemed to be a consensus of these oiled filters falling short in the absolute percentage of dirt holdback.    Which all ties back into how good the air filter is on the engine at keeping dirt out as that is going to reflect as a contaminant introduced into the oil as well as cylinder wear even if some of that dirt does find its way out of the exhaust rather then the crank case. Put another way that one can throw the kitchen sink at filtering the oil and using a bypass system which I fully expect will do nothing but good for the oils contamination but if the air filter system isn't doing its job then its preventing the engine from reaching the best wear/lasting case scenario instead.    Now perhaps this topic is or isn't for this particular thread but Grumpy Bear or anyone else for that matter, do you have access to some scientific trust worthy testing on engine air filter types to get some proper comparison data to post up.
