I do not regret going to a Turbo AWD but I still apreciate to see someone do some work on an NT.
You can also give a little more timing advence. I went as far as 12 ** base timing with some 94 oct.
I would like one day to see someone to go with 12:1 Slugs and a litle more agresive Cams.
I think that 175hp could be obtainable, maybe more.
