780's ? I think you guys mean 720's. Either way, you don't need that much fuel for a little 20G. Unless your road racing, 550's are plenty,
but 660's would be alright assuming you have a way to lean the car out ( VPC, AFC, etc. )

get 660s I got 550's for my set up on my gst and now I wish I had gotten 660's. I have another car now with a new set up and I'll probably have to buy new injectors again. I should have went bigger the first time.

No I think he ment what he said. I have 680's and was going to buy 780's

no i have 550s but i'm going to buy 680s or 780s because there is only a $10 difference.between those 2.

extreme psi sells 680's and 780's maybe they just flow more because the ball/disc injectors.

this is there ad


Custom machined ball-style fuel injectors. Able to run at higher sustained duty cycles and have better atomizing characteristics than regular pintle-style injectors.We took the time to send a 4G63 head, intake manifold, and fuel rail to specifically have our injector shop program the CNC machine to fit these on DSMs! Comes with free O-Rings!

Below image are 750cc. You will be getting 680CC!

I think you should go 680's. The 780's are probley a bit much. Im going to be runnning a 57 trim t3/t4 with the 680's. So if they are ok for me they will do fine for you
