Don't let the door hit your ass on the way out. You just have to keep in mind, 99% of people here don't have the knowledge, ability or tools to make a similar 190hp without power adders. By statistics and your to date posts, it is highly likely you are one of them.
When you have an inexpensive nearly bullet proof bottom end from the factory available, why on earth would you not want to use it?
The stock TC bottom end is good for a repeatable 400hp. With some descent rods, it would be good for over 600hp. The ****ty stock NA pistons, or some keith black Hyperutectics might be good for 250hp on an NA, but ping once while running juice or boost, and you will have a toasted shortblock.
So why are you so determined to do things the hard way? Pick up your work where ford left off. Get the TC bottom end, the TC computer, air meter and injectors (30 or 35lbers) and run it NA with a bunch of nitrous. Just throw a head that you build up for higher CR (you could easily get over 10:1 shaving the head, even with the TC dish pistons). I've run the turbo ECU setup on my NA before, and it works fine. Just requires a bit less timing since the CR is higher. Then, you have the bigger injectors you need, along with a STOUT bottom end to take some abuse.
After you learn that a 2.3 NA on nitrous sucks ass, you will be throwing the turbo on, and learn a tiny shot of nitrous with a turbo engine will get you more power than you can handle.
I ran a mildly modded NA 2.3 on nitrous (75 shot), and later with a turbo.
no nitrous, 18s at 75mph
75 shot, 16s at 81mph
16psi boost on pump gas (mildly modded TC engine) low 14s at 98mph.
16psi + 75 shot???? wouldn't surprise me at all to see 12s. Someone here already did that with a much much more stock motor than me.
