Hey guys just wondering if these are fine. BTW the car is a 94 lt1 trick flow 195cc heads/CC465/Edelbrock Intake Manifold/58MM TB/Cold Air Intake/ and LT's with true duals/X-Pipe/cutouts coming soon (like a month soon). My plan is the far future is to build a 383 with the same heads i have just a lil bit of a stronger cam, after that i will either spray a 100 or 150 shor or just put a procharger on it. I found these injectors tell me what you think.( I do plan on buying a racetronix fuel pump the whole kit they sell) it says they flow 60lbs at 43.5 psi which is what the stock system is at. So i should be fine with the stock regulator? as long as I get the new pump just to be on the safe side?

thanks

 

Whether you need larger injectors for nitrous depends on whether you are running a wet system or a dry system. Only a dry nitrous system flows the extra fuel for the nitrous through the injectors.

With a wet system, you size the injectors for the normally aspirated engine flywheel HP. The extra fuel for the nitrous is added through the nozzle or direct port system. At 63 #/HR @ 43.5psi (they flow 60 #/HR at 39.15psi) they can support 900HP - way too large for your current setup.

Buy the correct size injectors for your current setup. 36 #/HR would appear to be more than adequate. Add wet nitrous and keep the 36's. If you add a blower, sell the 36's and recalculate the required size for the blower. But when adding a blower, I would also upgrade the fuel system to 4 bar (58psi).

A 255LPH pump is a good idea. Stock fuel pressure regulator will work fine.

 

K what brand should i buy? So just get 36lbs injectors and upgrade the pump, and that will be fine. Are the 36 fine with a 383 set up

 

36 #/HR will support 515HP at the flywheel. If you feel that's not enough, go for 42 #/HR. The stock PCM will handle the 42 # injectors.

I can't recommend a specific pump. Ive got dual 205 LPH Bosch pumps, one in the tank and one off a sump at the bottom/back of the tank. They are extremely reliable, and flow well at higher pressure than similar pumps (I run at 58psi). But one pump will support about 500 HP. And the in-tank mount requires modifications to the Bosch pump.

 

Alright thanks but i meant what brand injectors are good?
