wanna upgrade from stock turbo

just found out my turbos toast. i really have no idea what to get. i wanna go as big as possable but without messing with alot of the stock parts. i was looking at the 16g and the 14b if anyone could give me some solid advice it would be awesome thanks. i all ready have 3" real apexi exhaust, injen intake, apexi boost controller.
thanks guys

14b is an awesome starter turbo. You can run it without having to up grade the whole car at once to take advantage of it. And its still enough for 12s. I did very well with one I picked up for 125 bucks with 120k miles on it ;)
Plenty of money left over for fuel mods and the like.

To run 12's on your 14 b I am confident you upgraded your pump what injectors did you use? I assume that was on race gas pushing the turbo into low 20's psi?

As I said above, the 14bs are cheap, leaving plenty of money for fuel mods and the like. But, I ran stock injectors deep into the 12s. I did run 20-24 psi on race gas, using the stock pump to 12.8s, at which point I put in a 190. With the 190 and stock injectors, I damn near ran 12s on pump gas. I only tried it twice EVER, and ran a 13.1 at 103. I had previoulsy run 12.9s at 103s, but I couldnt put it together on that run. My best 14b run was 12.74, so race gas didnt help a whole lot in this case ;) 13.2-13.4s were more typical on pump, and that is the configuration I ran on the vids on my page at POSracing website. With 550s and a better intercooler, you can get into the 12s much more easily on pump gas and a 14b. You need to know how to tune though ;) On the small turbos its all in the tuning.

If anyone hasnt seen the vids on my page at www.posracing.net, check them out if you are interested in 14B 2Gs. They are emarrassingly slow, but low 13s still whoops up on almost every "street" car at the track. Stock twin turbo rx7s, older cobras, etc. I had my share of wins on that little 125 dollar turbo with very few mods. :) In the vids I spank a WRX, and a golf VR6.

EDIT> I'm putting them in a new thread, since I started to ramble on as usual, and I dont want to hijack this one. ;)
