Hey, I'm running an alky injection kit at the moment but I was wondering if I should/need to upgrade the injectors, I'm also debating on either getting an evo9 turbo or a BR 20g-9 in the near future and which ever I choose I will port the hot side, Basically will it be wise to upgrade to 680cc inj. or will it just not really be worth it? BTW: This is not my account I logged on to my friends to post. So can any one give me advice? I've seen tons of guys not upgrading injectors but then again lot have.

 

well what are your other mods?

 

To name a few I've got....

- BR TBE with Test Pipe
- MBC
- Forge BOV
- 255lph fuel pump
- Buschur Flash
- BR Air Filter
- HKS cams 264i/272e
- Upper and lower I/C pipe with BR FMIC
- Exhaust Manifold (Ported and Jet Coated)
- Ported and Jet Coated 02 Housing
- Alcohol Injection Kit
- Samco Radiator Hose Kit
- Radiator Cap
- Radiator shroud
- Hyper voltage system
- Ralliart Thermostat
- BR ported hotside, I'll bolt this onto my new turbo, Going for the 20g-9-5

So should I add the injectors?

 

Yes, YOu should have had them installed already. I would go 680's or 780's!

What are you tuning with? Flash,SAFC2, AEM?

 

What do you think? 680cc sounds enough too me, I'd go with those but what you think?. I'm using the BR Flash.
While on the subject am I missing any other mods or will I need to add anything else you can think of after the turbo comes? I'm going with the 20g-9-5. Thanks

 

680's should do the trick

 

No, alky means you dont need injectors. It significantly lowers the IDC.

 

O, I've seen a lot of people run akly with upgraded inj. but still I know you run it. I just wasn't sure sense I've seen both. Any of you guys above run alky. I was just wondering If I needed then to be "safer". but I guess not.

 

To be sure, you just have to check your injector duty cycle, then decide what percentage is your limit: 80%, 85%, 90%, 95%? It depends on how much alky you're spraying, how much fuel is being removed, how much air is being pushed. You can't just randomly guess on these things, but since alky burns as fuel in the cylinder, that causes us to have to remove a TON of fuel with the tune...therefore, less injector use.
