Gt3076r

[tinys s14]

If I put a gt3076R on my sr20 would I have to upgrade injectors?

850cc's fasho

or you could just run 4-5psi:werd:

Yes, you most definetly would. Even at the lowest boost you could get, you still would probably be at the max for the stock injectors. Remember, psi is not what you are looking for as far as measuring the air. Its CFM's.

DO NOT SKIMP on your injectors

Make sure you get high quality ones like SARD, and i recommend sticking to Side Feed High Impedance if you use a power FC or Tomei unit that is based off stock parameters (as a starting place).

I was wondering about this myself, I recently switched to a top mount gt35r and looking at what injectors I should run, cc's, top/side feed, and brand. I'm using the tomei standalone as well. Any suggestions.

I would got with Side Feed 850 CC SARD's and run a Denso 295 LT/HR fuel pump with a good quality SARD Fuel Pressure Regulator (or aeromotive even better).

You can run base of 42 PSI with vacuum connected at idle to get the SARD's to push even more fuel (flowing more liek 920 CC inj depending on load range)

This is enough for 550 True WHP which is about the max you will want to run out of a GT35R on a street car (about 675 brake HP) This is about 26 psi or so.

Another option is 1000 CC Denso - they actually do have these you just need to contact Denso, then you can get away with a lower flowing pump but at HP levels over 500 I really suggest having A VERY high quality Fuel pump and even consider the Waldon or Aeromotives

I was told by a local shop that the spray pattern on the side feed is not as good as the top fed, and the top fed can move more volume at the same pressure. I'm not an expert but I'm doing all the reading and asking I can to determine the best route.

I currently have the Aeromotive FPR with 6AN lines, however it was recommended that I do a top feed rail and 8AN from tank to rail since the OEM hard lines would produce the pressue I need but at a lower volume, then I'll have to bump up the pressure and higher pressure will again mess up the spray pattern.

get sard 850cc

i personally run denso 850cc but to me they look the same..

big single port

whereas nismo injectors are 740cc but they are 4 ports like standard for a finer spray.. but really
as if your going to be able to tell


you should make 350-420rwhp on your 3076 depending on whats done to your motor and how much boost you run with pump fuel
