OK did a little digging and it looks like the 3.0 I n52 and the 3.0si n52 have the exact same cams, there is no difference. also the exhaust also shows to be the same, all that’s different is there is the tips which can be bought for 50 bucks each, the real difference looks to be the intake manifold which can be had for 250 dollars from the scrap yard since it is a three stage vs. our 3.0I one stage.

I talked to a fellow from craven and he told me this "Hey Christian,.
If you do the entire parts swap, then yes you will be right with the z4si we just retune the computer for all the new parts. I am almost positive the cams are not different, so it should just be the 3 stage manifold that you really need to make the power."


so in theory all I need to do is install the 3 stage intake and have them install the si remap and recode the computer to recognize the other 2 stages and then the extra 40+ hp can be had for about 600 bucks all said and done either way 40hp for under 1000 bucks aint bad.




so what do you guys think am i dreamin!
or could it be that easy!
