The Burning Rom Posted September 7, 2003 Report Share Posted September 7, 2003 Alright, I have two questions. The first one is, are the lower intake manifolds from the 3100 different than the ones from the Gen II lower intake manifolds? I don't have a Gen II manifold out of a car to compare the 3100 manifold to. Also, does anyone know if there is a good HD High Volume Oil Pump for the 3100 motor? I know http://www.mantapart.com has one for the 2.8/3.1, but I'm not sure if I can get it to work with the 3100. So, I was wondering if anyone knew of any other options? Any info is much appreciated!

mfewtrail Posted September 8, 2003 Report Share Posted September 8, 2003 have any idea what the part number for a standard 3100 oil pump is? I think "Melling" makes HD oil pumps for at least the gen II's if I'm thinking right, they might have a HD application for the gen III :?: Quote Link to comment Share on other sites More sharing options...
The Burning Rom Posted September 8, 2003 Author Report Share Posted September 8, 2003 Thanks for the response Robby I guess I'll have to find another "donor" 3.1 Matt, the GM Part# for the stock 3100 pump is 10229785. Thanks for the reply! Quote Link to comment Share on other sites More sharing options...
fleetwoodguy79 Posted September 8, 2003 Report Share Posted September 8, 2003 Why are you wanting to put in a different oil pump? The stock pump puts out PLENTY of pressure, what are you doing to the engine? I'm running a 3.4 DOHC with LOTS of work done to it and I still only need stock pressure.

The pump I have has 145,000 miles on it. The engine is going into a TGP with a larger turbo, aux. oil cooler, dual remote oil filter, as well as a bored block. I want a little more than stock pressure Quote Link to comment Share on other sites More sharing options...
mfewtrail Posted September 8, 2003 Report Share Posted September 8, 2003 Jason, Autozone lists the Melling HV(high volume) oil pumps...I looked one up for a 95 GP w/ the "3.1 SFI" as they list it...it is listed as part number M-134HV (3 month warranty), the regular melling is listed as M-134 ....the HV is actually almost a $1 cheaper than the regular one..they also list a "Hi-Tech" HV oil pump w/ a 2yr warranty for $83 ..Hope this helps! EDIT: btw, the same melling HV's are listed for the 3.1 MPFI's Quote Link to comment Share on other sites More sharing options...
