Scionlife is not the only place to learn about the basics of internal combustion engines. Google 'how does an engine work' If you find a website with a term you dont know or understand, google that word, you will learn yourself gud. I started from scratch and have a MUCH better grip on things after 3 real months of studying and learning.

you are gonna turbo soon right? coz you will not gain anything without mods.. built short block is just to strengthen your motor to take the power your turbo creates.
I strongly suggest reading about forced induction and how things work, there are tons of infos you can find online or you can buy books. Remember the principles and concepts and not the hp the literature tells you, opinions can be subjective and vary from other sources

There are obviously tricks to get power out of a n/a motor, and the build is a large part of that. HP gains are all about airflow and maximum compression without detonation, so for a n/a build you'd increase the compression ratio to maybe 11.5:1, get different camshafts, maybe a head port, and a stand-alone ECU to retune more agressive (i.e. leaner) and up the RPM over the stock limit.
Realistically since no one builds for n/a all parts would need to be custom, it would cost between $5-7k before the tune, and you'd max. out around 200 WHP. Unless you're just trying to be that different, it's cheaper to turbo, and with a higher potential for gains (300-400 WHP).

I agree 110% but 200whp mark has been broken with under 2k in parts and usually no extensive head work, OS valves, 7 angle valve job, or stroker kits for that matter, thing with the ptuning block is that its low compression,(boost) but our motors our low right out of the box so really if you got it custom tailored to your specs, it would be a bullet proof ( no gain ) stockish-block

^ was asking bout ptuning short block so its a FI short block.. sure he can let them put high comp pistons instead but the OP is doing research on FI, looks like he is going that route later on but just want to check if he would gain without putting the turbo system yet
awesome! lol
awesome! lol

Would this equal to a loss is tq? Im just starting to hear more and more bad news about trying to stroke my motor.
