Another Injector question - Siemens Deka
 

I've been reading through a lot of builds...and haven't found anyone using 60 lb/hr Seimens Deka IV Mototron injectors...is there a reason why they would be undesirable? (...other than the connector being different...)

Thanks!

We like PNP and what is known.

what is the COMPELLING reason for using them? the $50/ea price?

[and I believe is is Siemens]
and it looks like you can get them as either EV-1 or EV-6

Price certainly is an interesting portion of their attractiveness...when compared to buying a set of junk-yard RX7 injectors, then having them cleaned...the pricing is getting comparable...plus they are new...and may have a better spray pattern (yes...I said may)

I've used a set in the past on another project (Saab 2.0l Ecotec turbo), with good results, but I didn't have any other comparison injectors on that car...

interesting enough to have me considering replacing my Delphi 50-lb'er

My only worry is being able to idle the injectors well on a 1.6...

ev1 and ev6 is injector types and has nothing to do with injectors from siemens.

I believe he was just referring to the connector compatibility...

which has nothing to do with the connector.

The connector has nothing to do with connector. Its so obvious now.

I meant ev1\6 are not connectors, they are injector types from bosch.
The connector shown in the link is a minitimer connector
The other deka injectors have a USCAR connector.

well then educate us, what exactly do EV1 and EV6 mean?

"USCAR (EV6) & Minitimer (EV1) connectors available!" from the deka advertisement

I did
Look an EV6 injector with a minitimer connector

The EV6 injector pic in your post has a USCAR connector.

"USCAR (EV6) & Minitimer (EV1) connectors available!" from the deka advertisement

Your point is what? That you keep finding people that just use ev6 and ev1 for search words in search engines? ev6, ev1 aren't connectors despite what people may say in their website. their injector types from bosch that can and have different types of connectors on the injectors.

Look an EV6 injector with a USCAR connector on it.

Look an EV6 injector with a Minitimer connector on it.

So, if I understand your point... the marketplace generally refers to the connector based on the original connectors supplied these injector types...but that's not always the case...

For reference, what is the name of the connector on the Miata injectors?

In my last post what is the connector in the bottom picture and what is the injector type.

I would guess its liek that way because a lot of the EV1 injectors have minitimer connectors and everyone generally thinks they are refered as EV1 connectors. I've seen it on forums and in person. Just keeps going on like this because websites like that list that because either they know it as that or use it as search keywords for other people that know no better.

okay, found this

"The EV1 is the earlier design type: it is a pintle injector, meaning it has tapered needle that atomizes and sprays the fuel into the engine. The EV6, on the other hand, is a disc-type or "director plate" style injector, which has four small holes to better atomize the fuel."

now what are EV14s? how do they differ? do miatas use 48mm or 60mm length?

EV14's are the newest injector type from Bosch
composite materials make up the shell of them, they also have smaller internals compared to the EV6's and overall are a better buy compared to eariler bosch injectors for people going standalone.

I'm still interested in the Siemens deka V twin spray 39lb\hr fuel injectors.

You should have no issues provided you have a good ECU and a tuner that knows what they're doing. We have a 1.6 car that idles perfectly well with a similar Continental 80lb injector on gasoline. There are plans to move to E85, so we fit the injectors. They were chosen because they were inexpensive and essentially a drop-in fit. Just haven't filled it up and made the fuel change yet.

We also have 1000cc IDs on a 1.8. It was originally setup for E85 but recently switched back to gasoline. Idles perfectly.

The newer injectors, especially the EV14 stuff, are just so much better and consistent at low on-times than the old EV1s. It's really amazing how well they work. ECU components play a role in consistency at low on-times as well.

Completely agree: EV14>all

I installed a set of 1150cc FIC EV14s in a MS2ed 1.8L last week. Idles perfect at 14.7, amazing stuff.

I'm going to have to buy some new injectors for my MS3x install. Sounds like the EV14s are the way to go, being the newest technology out there and all. Since it's been done already, there must be some experience out there.

The EV14s look physically different from our stock injectors. What do I need to do (mechanically) to hook them up? Are there adapters? Different electric connectors shouldn't be a big deal, but mechanical connections, making sure there's no leaks seems important...

As long as you order the right ones, they drop in like stock. There are a few options for wiring (pnp/pig tails ect) AFAIK

If you order Injector dynamics they will drop in like stock. You either get PNP adapter clips for an extra $50 or so, or you get the stock injector clips and wire them in yourself. If you go to the ID website they have the part number for the correct crimpers on Waytech to make hooking up the ID pigtails. It took me all of 15min last night to put on the correct pigtails.
