850 cc secondaries on turbo 2?
I have a 1st gen with an 87-88 turbo 2 conversion, stock turbo, upgraded front mount cooler, cartech fuel pressure reg, custom 3 inch turbo back exhause with no cats boosting 13-13.5 lbs. 2 months ago, I put 270.8 hp to the rear wheels along with 243 lbs-ft of torque. Anyways, next year Im going bigger turbo with slightly lower boost in hopes of making around 320 rwhp. My question is if I don't want to run 2 additional 550 injectors with and aic (like the sds one), what would I need to replace the factory 550 secondaries with 850 cc injectors ( I think they came on the 12a turbo. I need to go stand alone, don't I? Which is easier to setup/price difference? Thanx.

i dont think you can if you have the stock ecu, i would go get a sds computer or something else depending on your $$ flow then keep the 550's and run 1200's that is plenty of fuel for 450+ hp

I got an 87 GXL 6-Port turbo converted running on a stock 6-port ecu and 12A Turbo injectors. It works just fine!!!!! Also I am running on 8 psi of boost.
