Just got a set of these in with Mitsubishi adapters on them for DSMs, Evo 8 and Evo 9. 2200cc at a 43.5 base fuel pressure and they are capable of being run at extremely high fuel pressures, unlike most fuel injectors.

The 1000cc version of these injectors tune, idle, and respond like a factory stock injector. We have tuned a bunch of S2000s, Acura RSX's, and turbo B-Series cars on the 1000s and they usually run amazing. The 2200s should hopefully kill the 1600s out there in idle quality and drivability. The main problem with the 1600s is not that they are too big, it's that they are just a poor injector and do not have linear enough flow, a pulse width of 1.5ms can actually give less fuel than 1.25ms. That can cause problems and force you to have to run the car richer at idle and part throttle with the 1600s to get any drivability.

I am trying these tomorrow on an Evo 9 with an AEM EMS on it. Even with an aftermarket peak & hold injector driver box, the AEM EMS can't handle the 1600s very well, so this should be a good test.

are these the Injector Dynamics units that T1 sells?

they look really nice how will would they work on link

Yep. They are a step up from the big Siemens Deka injectors as far as tunability goes.

They should work great, since the OEM Mitsu ECU injector drivers can handle the 1600s and 1650s better than most ECUs. The 1600s/1650 aren't perfect with the factory ECU/DSMLink, but at least the car usually drive decent.

They are very expensive, but they avoid having to goto a 2 fuel rail setup, different intake manifold, and 8 injectors on a lot of cars(1000s or smaller primaries for idle/drivability with 1600 secondaries coming on under boost), or if you actually need more than 1600 of flow.

Very expensive is right! Sheesh!

around 240.00 each

might have to save to get a set for the spyder when I start working on it some day. but whats a few more years since it has been apart for almost 8 years now

:shocked:

That's a bargain when you figure in how much it takes to have two rails, eight injectors, and the corresponding fuel lines to do it. Plus you could run these with Link, doing eight injectors with Link takes some measures I wouldn't be comfortable with. At least before the new version came out.

Well, they seem to work very well. No problems controlling the A/Fs at idle or cruise, runs/smooth fine at 1.0 lambda cruising part throttle. They respond like a normal injector, tune like a PTE/FIC 1200-1250.

Wow! What local evo9 needs these? I wanna see the dyno chart ;)

^^ I'm guessing maybe that white one that sat in their shop forever.

better off buying these vs buying 2 sets of injectors at the same price, then avoid buying the extra rail, extra lines, and extra tuning required to run so much stuff

That was an Evo 8 from a couple years ago.

that makes RIDICULOUS power

That's a lot of money. I wish there was a proven 1600 size injector that would tune like a smaller injector and take care of the "drivability" issues that most 1600's tend to cause.
