200cc 200% injectors for 99.5 7.3

Jnorton · Dec 20, 2020

I was wondering about this injector I have a kc 300x turbo and fed, and hydra. I will be doing studs clutch spring and pushrods with the injectors. I'm looking for people running these and there opinions.

Unless someone is making a tiny hybrid, those would be an a-code injector?

You better have lots of hpo, or spot on tuning to get decent power and smoke control.
200% nozzles will eat a lot of oil. I'm using 180/80%s, and I can make a lot of smoke, if I want to.

What power level/application are you shooting for?
180/80s, with supporting mods are good for 425-450 hp.
A 238/200% will get you 500-575 hp, with supporting mods, and good tuning.

Swamps is the manufacturer and they are hybrid. I am looking for 500 hp and want to be able to tow, which I understand is all in my tunning and right foot

200cc/200% is definitely the wrong injector for you then. If you want 500 hp (on a max tune, not while towing), but still want to be able to tow, then you need 238/80. Which turbo exactly do you have? KC 300x is a line of turbos with multiple size options. Either way, a T4 kit with 364.5sxe of 366sxe will be much better for your goal.

Out of curiosity what kind of egt do you see towing heavy with your setup

I don't tow heavy so can't say. On a hot tune unloaded really getting on it, I can hit 1400-1500 pretty easily if I want. With a tow tune or daily tune though, it doesn't send enough fuel to heat up too bad; about 1000 max.

Well I guess we will see what happens I have the 200cc 200% injectors and their pushrods, valve springs, and arp head studs ordered. I guess worse case it's only about a 4 he drive to their shop if I need it live tuned

How did this go? Swamps has new owners in the last 2 years and have had nothing but trouble. Did you actually receive your injectors?

If so, how does this setup work?
