HP is not everything some times.. and if all you do is spin tires then how will you win a race??? we can drive on DR all the time lol..
i would look up head packages that zpi offers.. maybe thats the upgrade your looking for to really push your car...the head can make a HUGE difference.

I hope that we do see some good gains from a nice p&p but I just dont think the gains are gonna justify the costs

What's your point. Stock for Stock we have less hp than an SRT-4. Put us on 8 PSI of boost, and we put down more power than an SRT-4 (forget what PSI setting they come with from the factory). So, you can't compare totally two different engines.
You should check back on that k20 Teggy from time to time to see how long it last, IF it was stock internals. They come with like 11:5.1 HIGH compression pistons in them. I'm just curious to see how long that motor last like that. All the New 06 Si's in the mags, that have been F/I, 99% of them all had different LOWER compression pistons in them. NONE were using stock pistons.
20-22 Psi stock for an SRT-4 Wrong! I have an srt4 and from the factory it is set at 14lbs of boost.

Don't ever compare an Integra to this car. I had an Integra in 2000 with a Drag turbo kit and let me tell you how quickly these things eat motors. I personally sold the car on the third motor.

I wasn't doubting it, I just asked for you to keep an eye on it's longevity.

Now grant it the engine from the dealer makes 40hp more than our cars but damn 501whp!
I would not doubt itI love TQ....

kinda new to the FI thing. I'm just curious just want kind of internals are necessary to upgrade to safely run at 250-300whp as a daily driver. Are pistons the only things you need to switch out, or are rods also necessary?

250whp stock is fine...300 you may want to look into pistons/rods.

You really have to take into consideration what comes in a honda motor. The k series is notorious for having extremely large stock vlaves. In fact in many cases making the valves much larger loses power. Also take into consideration that they have i-vtec. We have vvt-i. They are different. If we had the vvtl-i like in the celica or the matrix xrs it would be more on the same playing field. For those who aren't aware of the difference vvtl-i has 2 cam profiles like vtec. At 6000rpm it will switch lobes. On top of the constantly changing intake cam timing from the vvt system. In our motors we do not have multiple cam profiles just intake cam timing adjustment. So in theory building the head and installing aggressive cams would make a world of a difference.
