jeffer949 Posted November 5 Share Posted November 5 HI. Im getting ready to build up a L28 for my Maxima wagon to replace the L24e that I've turboed. It will not be a high horsepower build. I have the stock MN47 head and I have a N42 head. What are your thoughts on which to use? I know the logical answer is sell both and buy a P90. But lets just say I'm odd and like working with what I have. I do have the ability to run E85. Looks like with the N42 I would have a compression of about 8.2:1 and the MN47 would be 8.97:1. Running Speeduino ECU with COP . just thought Id see what your thoughts are on here. The MN47 is currently running on the L24e engine with about 7 PSI of boost. But is pretty laggy due to the stock Torque converter and only being 2.4l pushing the Turbine housing that was used for the 2.8l. Quote Link to comment Share on other sites More sharing options...
madkaw Posted November 6 Share Posted November 6 What block are you using ? Will this be a NA build ? MN head makes for a great street NA especially if you have a flat top block . Put a cam in there and go ! Quote Link to comment Share on other sites More sharing options...
jeffer949 Posted November 6 Author Share Posted November 6 Its staying turbo. I have a n42 block and I'm likely going to throw some itm turbo pistons in it. So the question is which would you use for an unconventional turbo setup Quote Link to comment Share on other sites More sharing options...
madkaw Posted November 6 Share Posted November 6 I’d say it’s a toss up . Most wouldn’t run the MN head because of the liners . Better NA head for sure , but it would work . Quote Link to comment Share on other sites More sharing options...
