Budget build and boosting the F20c motor dont mix. They key area you are skimping out on is fuel delivery, find a good set of used ID1000s for like $350 US on the for sale sections. The two key elements here are fuel and the tune, dont cheap out on any of that or you will spend a lot more money replacing the engine. Running the engine completely stock will work just fine. Weld in a baffle into the oil pan and run a full stand alone ECU like AEM EMS or Haltech Platinum Pro.

Whatever you do dont waste your time with running two sets of injectors.

 

I don't see the point in dropping £400 on a set of ID1000's when there's a set of injectors and a fuel rail on the shelf that will give enough fuel and gain a little standoff for better mixing at high rpms.
What will ID1000's offer me over the simple route of 2 sets of injectors?


It's having a dry sump, a baffled oil pan isn't go to cut it after having a look at the motor, I think we'd end up grenading it in short order. And I need the ground clearance, the stock sump is too big after fitting the engine up, pace pump/pulleys/fittings are on the way and the sump pan is being cast as we speak


As for budget, you'd be surprised what I can do on a budget
Most people probably spend more on a set of wheels and some underbonnet shiny things than we'll spend putting this entire motor in....

 

the ID1000s offer a far superior atomization to the OEM units, the cycle rate is far more accurate as well.

ID1000s are pretty much the benchmark standard with the latest in injector technology. They are essentially Bosch injectors with a modified nozzle.

They also come with a cool high quality card in the box that says "Welcome to the club"

I would go with whats proven in the community and the fact that everyone here is telling you the same thing. Why ask a question if you're going to ignore the advice given to you by the people who have been there and done that ? We see it all the time here on the boards and the person usually almost always learns the hard way.

 

I run ID1000 myself, and they have proven to be the best for their delivery size, but I question whether they do actually atomize better then our 360cc injectors. I would be surprised. Better atomizing over some RC injectors of any CC, I would total agree. If the OP has the ability to properly execute a twin injected set up, I wouldn't doubt that this would be totally reliable and a functional rout to take. Your getting proper/safe/reliable OEM atomization of 720cc delivery.

OP, add an adjustable fpr to increase fuel pressure along with your EMS adjusted duty cycle and you should be near the 1000cc fuel delivery headroom that will make everyone feel cozy.

 

I've already got an adjustable regulator and 044 pumps feeding the fuel system, that's not an issue.

 

I don't mean to sound like a dick here, but it'll probably come across like that anyway

If the ID1000's are soo much better than the OEM, why aren't people dropping them in as an upgrade even for stock engines? I'll take a guess, because they make naff all difference and the idle is probably slightly worse?

As for going with what's proven and the 'been there, done that' thing, I had a good look around and I can't find anyone on here that has even tried a twin staged injector setup? Please correct me if I'm wrong, I'd like to know about it if so.
I do know of one running twin staged injectors elsewhere on an N/A build and it picked up a few lbft in the 5-8krpm's area purely from the better atomisation due to the injectors being much further upstream at high airspeeds, are the ID1000's going to outperform those even with that advantage?

And there's the other side to look at, if I drop £400 on injectors, they need to provide £400 worth of benefit, as that money could be spent on other area's of the car that I'd imagine would make 100x more difference - it'd get most of the way towards a custom plate differential for the transaxle for example.

I can understand they may make a great upgrade for a stock car, with them being a bolt in, easy solution that works without the need for standalone management, custom fab work, etc, but neither of those are an issue beyond half an hour of work to mount a second set for me.
For me, the only thing that matters is, will twin sets of OEM injectors be enough, and will they work?
To which it appears the answer is yes, and then, by extension, do ID1000's offer £400 worth of improvement over twin staged sets of stock injectors?
Which I really can't see at the moment, unless someone can give me some data that proves otherwise.

Hope that helps you see it from my side of the discussion

 

Well you already know my answer as I just posted above. And I run ID1000. I have to side with the OP's logic in this case. ID are great injectors that deliver a lot more fuel then stock but yet idle like stock, but does no one any good to upgrade stock injectors if you have another less expensive means to get the same quality of fuel delivery that you need. If adding a second set is how you go about it then more power to you

 

Right, so there's no real benefit to ID's other than they're easier to fit than going with twins?


Twins it is then

 

Just run twin oem and tell us how it goes. Where are you mounting them? I presume right near oem ones so you gonna get a special intake manifold or fuel rail to accommodate it? If your just gonna spray them into the intake track stop and don't do it. That's basically a wet shot of nirous and you can get fuel puddling.

Full blow did twin injectors setup. They ran I think a special intake manifold for it. Or maybe special fuel rail I can't remember. Anyways. Worked fine. But they did it cause huge injectors can be finicky for part throttle. So they ran staggered set.

Your hell bent on doing it so do it. For us its not worth it. I run 900 cc injectors and make 450whp. Car runs great idle to wot red line and everything in between. Attomization my Ass they work fine.

 

They'll be in the plenum aimed straight down the intake tracts, no need for a special inlet/fuel rail, just weld some bosses in, the fuel rail has been converted to a return setup anyway so just a case of plugging one into the other.
