I am running rc eng. injetcors in my 2.0. I chose to go with the 330cc along with a walbro 190lph fuel pump. The only reason I did this is because a am on laughing gas. If your running basic bolts ons, the stocks injectors will suit you just fine. I would only upgrade if you start building the motor internally or going Forced induction like SUPERFLY said. Any more questions, just ask.
The Pump ran me $90 and the Injectors ran me $80 each. The pump I ordered from a local auto parts store and the injectors I ordered directly from RC Engineering. I did these upgrades prior to my NOS install just to ensure propering fueling. I wasn't really looking for major performance gains from the pump, injectors and fpr....I just want to make sure that there was enough fuel to compensate with the nitrous. However when not squeezing, there are some noticable gain as long as the psi isnt cranked up to high. My motor is pretty built, so the upgrades in fueling compliment everything nicely. If you need part #'s for anything, just let me know.
I am thinking that I might need to replace my injectors soon anyway, and instead of trying to deal with the local dealer, I thought I might just get some that are just a little bit nicer then the stock. how many cc are the stock injectors? I'm planning having Paeco build me some ported and polished cyl. head w. big valves, the whole encilada. Plus I think that I need a new injector rail because I over tightened a bolt for the fuel pump regulator. Anyway, I'm not looking for anything like 550s or anything, just basically stock equivelant made by an aftermarket company.
Joe_Silver93.....I believe the stock injectors are in the ballpark of 220-225cc....Since you are planning to do some motor build up, you might wanna look into increase the flow rate. With the mods you plan on doing, your gonna be added more airflow, but to accomadate that air, your gonna need some more fuel. Just a thought....let me know how it goes.
