4AGE injectors

[AE86GT]

What is some good injectors to use in a 4age with bosch external fuel pump, surge tank stinger ems and a gt28 turbo??

ive heard 7mgte injectors work well

[mattysshop]

4AGZE injectors??? 365cc... reddish, orange colour..

[AE86GT]

Do 7mgte injectors fit ????

[Matt-AE86]

yeah, they are identical to GZE injectors. If you are using your 4age loom, you will need to change the injector plugs to suite and depending on ecu etc might have to run an Injector Ignitor.

You sure they're identical to 4A-GZE injectors? I thought the highest GZE injectors were 365cc while 7M-GTE injectors are 440cc.

[AE86GT]

Think he means they are identical in the size and shape factor

Ken is correct. They're both top feed, low impedance and are directly interchangable. If you want even bigger ones then RX7(550cc) ones also work well but are only single spray.

What would work best though??
what cc ??

How much boost you going to run?

Put it this way, a ST165/ST185 3SGTE injectors are 440cc. They produce 190/200hp SAFELY. They could probably supply 250hp, maybe a bit more. That's at the crank.

im using 1jzgte injectors in my 20v, if 16v and 20v injectors are interchangable then they will fit in your 16v. they are 380cc

[Big T]

20v ones are sidefeed high impedance so they won't work on 16vs. Just as a rough guide, GZE injectors should be good to 140-150kwatw, 440s to around 170-180, 550s to about 200-220. Note that these are theoretical values derived from an injector calculator which are generally known to calculate on the conservative side.

ive heard that standard wrx injectors r a good little upgrade for tha 4ages

Sorry, I ment Identical as in plug n play.

Try 13b turbo ones, the later model, as the injectors have the same plug as the 4AGE. There are two types so make sure you get the one with the rounded corners on the injector plug.

[NickAE86]

7m/3s will be more than ample

im getting a touch over 200hp atw on ze injectors with a rising rate fuel pressure regulator...i will be upgrading to 7m once i fit an ecu & up the boost

i belive the 440cc injecotrs in the 3SGTE can support more.. one of my good friends runs a gen 2 (st185 GT4) 3SGTE in his ST162 FWD celica.. with the following mods.. dump pipe/full 3" exhausst, and front mount intercooler... the boost naturally rose to 16psi which gave the boost sensor (green map sensor lookin thing) a heart attack.. once we fixed that it made 208fwhp.. and ran 13.7 @ 105mph.. with bad launches courtosey of super low kings that have been cut and shit shocks etc etc.. now has one of those e-bay stainless turbo manifolds, and a Gen1 3SGE celica inlet manifold with a custom plenham made on the factory runners.. un belivable for a stock motor.. just some bolt on bits to let it breath and open it up.. you would swear it has big $$$ motor work..

back on topic.. it hasn't been dynoed yet with the new manifolds on it.. but i think we have found the limitations of the stock ecu/injectors.. at the moment it feels like 240fwhp but next step is injectors and ecu.. so i think the 3SGTE injectors can handle a bit more than 250 at the crank.. but if there serviced and run a few more psi in the line with an adjustable reg i think you'll manage a bit more easily

[rileymoore05]

but will 3sgte injectors fit into a 4age? i was under the impression they were a side feed injector.
im in a similar situation, tring to find out what injector to use on my 7agte running a link ems and a t25 (mabey soon a t28) and a bosch external fuel pump.
