I have a 96 GSR with the Greddy 18G. currently I am running 310 injectors with the "blue box" that came with the kit. I've decided to up the hp and have it tuned better. Well a shop around me has a dyno and the guy can tune and burn uberdata chips. I'm going to be getting a walbro 255 fuel pump and rc 440's. Will 440's be enough to support 275whp? All this is on stock internals and 10lbs on the 18G.

There is someone around my city that is selling brand new saturated 440's for $150 and I'm planning on getting those. I dont plan on building the engine or upping the hp for a long time after I do this. Just wanted to make sure everything would be possible and I wouldn't be maxing out the injectors too much. Let me know. Thanks

 

i'd say thats pushing on stock fuel pressure

 

well... imo I would go bigger than what you need a bit... with Uberdata your tuner can get a stock idle even with 680cc or bigger inj.....

If you dont want to go over 300whp I would go with a set of 550cc minimum !!

But if I was you I would go with a set of 650cc or 680cc.... thats what I run in my car.

 

should i just buy the 440's and sell them for more? $150 is a good price for brand new injectors. i just dont want to pass up this deal

 

anyone else?

 

310s get used on NA setups pushing 200whp.... 450s are good to about low-mid 200s if i remember right.....

You'll want those larger injectors.

 

get 550 's and more cowbell. you gotta have more cowbell.

 

i make 236 WHP on a B16A Engine with 280ccm injectors and stock fuel pressure... and i have them at aprox. 70-80% dc in vtec at 8000rpm
