Anybody Confirm Injector Size?

[MrTerry]

Hey im going to order some 725cc injectors from Injector Dynamics for my 34gtt, but since they dont have rb25det neos over there in the USA they asked me to confirm the size.

Ive seen one or two people mention that 350Z injectors will fit perfectly.

Can anybody confirm that? I just dont want to order the wrong size, thanks.

hey mate i think Neo injectors and Z33 are interchangable

http://www.sardracing.com/products/Injectors.htm

there is a list at the bottom of the site showing the compatibilaty

maybe give them the part numbers for the Rb25 neo and see if they are the same??

hope it help

[MrTerry]

Thanks man yeah they seem to be the same, searching for z33 and er34 turned up more results than 350z and r34 gtt.

Looks like they are interchangable

[wasnt me]

have a read of this tread. there is local options for neo injectors

Oh nice! i guess ill pick up those bosch ones instead.

The Injector Dynamics are about 840AUD delivered, 490 for the bosch ones sounds better to me

Thanks for the help, I really appreciate it.

If you mean by Injector Dynamic ones EV14s then they are Bosch too .

The thing is that everyone's raved about IDs EV14s and how much easier tuning is with them - even with big ones like 1000cc and more .

If I had my time again I would have used them in My GTS25T instead of the Nismo 740s I have .

Those EV14 ID injectors are known to be very uniform very fast acting even at quite small pulse widths . If you do searches on them you find them OE on late model cars running higher than 90s era fuel pressure and often returnless systems . They do actually return fuel to the tank but most of them are in tank and so is the pressure reg .

If drivability and fuel consumption mean anything to you go with the most accurate fast acting and uniform injectors you can fit .

Your tuner if he's worth his salt will thank you for this .

Thanks guys so the Bosch ones are better then the siemens then? And the bosch fit straight it to an R34 GTT?

I was looking at these Siemens ones:

Would there be all that much difference between the bosch EV14s from tuffcarparts on ebay and the ID ones?

As far as i can tell ID buy the EV14s and carefully match them in to sets, is this worth an extra $350? I have no idea.

The ebay shop also says that their sets are 100% flow matched but i imagine they wouldnt do as much testing as ID, who knows!

I know its only $350 but i dont want to throw money around if its not really needed.

And Harey I dont know anything about the Siemens, but in regards to the bosch "wasnt me" said

i used these. went straight in no mods needed other then the injector plug.

these are about 950cc and idle perfect. can get smaller ones is you dont think you need that big.

in that thread he linked.

The Bosch EV14's from the ebay site are fine. They are flow tested they still had some the fluid left in them when i recieved mine. Dont forget that you will need to buy US CAR plugs to suit the injectors (same plug as GM LS1-LS9). These cost $11 each so there is another $66 you will need to spend.

[MrTerry]

Ok cool so just some of these plugs? Its the EV1 plug for the gtt isnt it?

[wasnt me]

im dont 100% sure but i dont think the stock ones are EV1 plugs and doubt that they would be.

give these guys a call and tell them you want USCAR injector plugs and tell them they are the same as holden gen2's

Ah k ill give them a ring, thanks for all the help

I got the 4 squirt Deka 610's. I cut, soldered and heat-shrinked the new plugs on and they have been running E85 perfectly for over 6 months. They were a little longer than my stock ones, about 10mm or so but I couldn't argue with the price, $500 all up.
