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.
