Default which size injector?

ok... down the road ill be finishing up my heads install. probly in a month + but for now im gathering parts.

62cc afr 205's 11:1 comp with stock bottem end.
ar headers 1 3/4 w/ catted y, gmmg catback.
the cam in my sig - 218/224 .555/.556 115+4 lsa.
1.8 yt rockers, ls7 lifters, 7.350 pushrods, ported ls6 oil pump.
fast 92/92 or the weiand/92 if it ever comes out, ft lid w/ 85mm maf.

im thinking a set of svo 30's should be fine since they are around 36's with ls1 fuel pressure. after everything is done im thinking i might want to put a 100 shot on it.
any opinions on these injectors? should i go bigger?

What HP are you estimating on? I can run the math for you.

On the 100 shot, is it going to be wet or dry?

Alright, wet nitrous has no real bearing on injectors, so I've figured for about 500CHP.

At 500CHP you need a 40lb injector at 43.5psi

So on the LSx 58psi rail, you need a 36lb injector.

We can easily modify your stock injectors to flow 36lb@3bar. It also makes tuning much easier since pulse and duration remain unchanged, so only the flow rate needs to be changed in the tune to get the car running.

With a complete reconditioning of your injectors, new Viton o-rings, and the flow change, we charge $30 per injector + shipping. And we ship from the USA, and most of the time, have a 1 day turnaround on this service.
