Dan what are you doing just getting advice from people on Internet forums and the building the engine from the parts you feel are most going to suit what you want?

I used to think like this and still do in some ways but its best to get a good tuner on your side and ask more buy less, i have wasted a bit of money in the past buying things i didn’t need but at least i stopped before i spent any major money

I would seriously call up someone and get some pro help on this build and not listen to people who know fuck all "like my self lol"

please keep us posted tho as i am interested in what you are trying to achieve
