You need to keep things realistic. You probably know nothing about motors, turbochargers and how it all works, or you wouldn't be asking if greddy could hit 500 whp. You have to realize that even guys who know their **** and invest tons of cash into k-series' rarely dip into 500+ whp, so I don't think you will either.garyward said:What parts would be needed to make a 2006 Si have 500whp (on track) with a Greddy kit and TiC exhaust?
It will be a DD using about 250-300whp daily.. and 500whp when wanted (not too often)
reading is much different from building, testing, and driving. that much horsepower is too much. If you want two different settings you are going to need something that can switch maps in your ecu first of all. And the only place you would need a 500hp fwd honda is on a drag strip, and if you arent racing it every day there is no point in getting it. Get a greddy bolt on kit if you want, and make sure you get everything you need with a turbo kit.. that kit does not come with everything to make it run WELL, (im going to get mixed opinions on this) and it will make 250 to the wheels which is plenty for the car.garyward said:I would like to have 250 -300 DD and a little more for the track. I have drove 1 srt4 which is not even comparable to the Si. i think the srt4 is a piece.. anything with more hp at lower psi would be better in my opinion.. i do know how turbos work but i dont know how to tell what will put out what or everything that is needed to create a kit. I have done MUCH reading up on kits and finding a median between 2 size snails to compliment between too large and too small. I guess i just have to wait until there is better tuning available.

I plan to upgrade to titanium rods and low compression pistons that should allow me to push beyond the 7.5/8.0 psi. I'm hoping to push the stock turbo to 17+ and run alchol in the furture to hit the 300whp+ mark.
