The more detailed you are, the better the suggestion will be. Drag racing? What model benched pump? What twins(housings)? Timing range? Hp goal?

just a hot rod, the pump is a 180 cpl 1863. the garrett t 18 has a 1.13 ar on turbine. not sure how much timing to run. shooting for around 700hp. havent got a small turbo yet or injectors. just got block back home from machine shop hot tanked and decked.

That Garrett T18 is old school Caterpillar, 86/111mm turbine, I would find something different. If you plan to run much timing, keep a 145° injector, for the price the 286110 is going to be hard to beat.
