Exactly. Honestly, in my opinion, the best way to go would be an NA build if you want reliability. Keep most of your stock internals, change out the cams, and make it an LS/VTEC. My guess is, with a NA build
might be able to do an all moter teg... nice decent cam, port and polished heads, bored over a little, *( not too much so you can't drive it daily tho..) exhaust, intake ect and remap, also a chip and what not....
you'll be able to push over 200HP with a $2,500 goal.

BTW, a turbo kit bought and installed for $2,200 is not possible! For a REAL good one atleast. You're not going to like this figure, but me and a lot of other TI guys agree that when you build an engine, buy a turbo set up, have it tuned and installed, your MINIMUM budget should be $5,000. With another 1 or 2K for emergeny repairs. Because things will break.

This figure is pretty rough, but I highly reccommend being prepared for turbocharging. Now, you can buy ebay crap and switch out the bad parts (ex. Turbo, wastegate) but it's just not worth it in my opinion. Personally, I was thinking about building a turbo LS with 350BHP/250-300WHP, but I can get around 220 (which is still 63% more power than I have now) for a lot cheaper, and it would be more reliable. Just my 2 cents!
