Currently peicing my turbo build together. Last turbo car I built was a 95 civic coupe with a b20b and gsr trans with a ls 5th gear. Had 550cc rc injectors and I ran that car on neptune rtp. Car was good for about 240 hp and the injectors were starting to hit 70 to 80 percent duty cycle.

Currently am building a 98 civic sedan. Has a b20b for now. Planning on running neptune rtp again. This time gonna have boost control setup on neptune. Want 2 different tunes with a low boost and a little bit higher boost when someone wants to play. So looking for 250 to 300 on low boost to 300+ on high boost. Just until I peice together something that will handle a little bit more.

Looking at injectors on the market it seems like everyone boasts about the id1050x for just about anything. Are they that much better than the rc injectors? And will the 1050s be too much injector for what I want or do they really have a stock idle down to the 300cc per cylinder they claim? What about grams injectors, fuel injector clinics, etc etc.

what type of fuel are you going to use? A set of 1000cc injectors with E85 will get you up to around 500whp and 650-700 on 93oct. I’ve got my b18c1 on 2200cc Bosch injectors and my idle is ok on e85 and 93oct is a little challenging to smooth the idle out. Don’t use RC injectors anymore, these new Bosch style injectors are amazing and crazy about the range of control they have. All the brands you mentioned would be great and you would expect good results from them. Any injectors below 1600cc would work for your build, but I would suggest staying around 900-1200cc range. Just consider your future plans when you purchase

I would agree. However, I do not think that such a large injector is necessary for such a lower-end amount of power. As a matter of point, you run on one map (or "tune") for the entire set of boost levels on the same fuel. You don't get into it in entire new tune until you change fuels. Then there is a possibility that an entire new map is made. That is only done, however, if the higher knock resistant fuel that you use is not petroleum-based, or uses an additive like methanol.

550cc even from RC can make over 320whp on 93 octane. getting something that is made from Bosch, at a larger volume, can do quite well for low and high power. So this is when, 750cc or so is optimal. However, as was previously stated, you need to stay what fuel you plan to use for the higher knock resistant boost pressure levels. Once you know that, then we can discuss how large an injector one would have for particular application

Oops dunno how I forgot which fuel. This car will be tuned on pump gas 91 as sadly that's what's around me in this lovely desert of socal. There is an e85 station about 30 miles from my house. Have been debating on being able to run both if that's possible. Would love to have a pump gas tune and then when someone wants to play I fill up with e85 to make a bit more power. Then run 91 to drive her back home.

I wont be making 2 separate tunes so much as having separate maps via Neptune. As you guys stated above it would be easier to do. That was my plan lol as the car doesn't have ac, so I can have my maps switch by simply hitting the ac button.

With all the above being said I think I'm still heavily leaning towards the id1050x. I just want a stock idle and the ability to make 400+ no issues when I get a b18c under the hood.

Current pic of the bay. Sleeper 4 door is what I'm going for.

ID 1000’s would work great, I just tuned a b20 turbo a few weeks back with some 900cc’s and the idle was smooth as they come

I'm running ID1000's (the model before they came out with the 1050X) and I put them in and drove on them for about 4-5 months before installing a turbo and they drove like stock. Whatever you buy, just make sure they come with a card that gives you dead times. This will save you some time and all you'll have to do is punch that info into your tuning software and drive.

You guys just reassured me in this purchase. And yeah those dead times are important! Doing the tuning myself so I know all about dead times. Order will probably be placed later tonight I will update on how they idle and tune.

I would only buy injector dynamics at this point. Also, dead times are using motec ecu/drivers, you may see yours be slighly different.
