Injectors swap - Toyota Nation Forum : Toyota Car and Truck Forums

I have 6 7M-GTE injectors, from an older Supra, will these injectors fit in a 4A-FE 1.6 litre engine.

Does anyone know the flow rate on either of these injectors as well?

What colour are they?

4A-FTE · 09-18-2002, 04:15 PM

Black, I forgot to tell you they are mean't for the 7M-GTE engine, they took them out and replaced them with the 7M-GE ones because they will be running an Vortech FMU and stock 7M-GE ECU, because it was cheaper to run the non-turbo ECU and FMU instead of buying the [proper turbo ECU... Lost yet? So will they fit?

7MGE injectors are 295cc.

As for fitment.... dunno yet.

These are 7M-GTE injectors, Deuce told me they were 550's...

It would appear the stock 7M-GTE injectors are 440cc, according to this. It would appear that the 550s are part of some sort of afm upgrade.

I know of a couple people that used 7M injectors in turbocharged 5E-FE's. Apparently, they will fit physically. The problem is that they have a different electrical resisitance... But I don't know what they did to solve that problem.

Thanks for all the help, thats very quick!! Either way, I think they are too big for my application. As of lastnight, I started to lean out even more, so I have to test the both pumps, and see if I need to change my fuel filter. So many little things to loof for!!!

4Aaron GE · 09-19-2002, 12:54 PM

you're leaning out?? Maybe its the FMU?

4Aaron GE · 09-19-2002, 01:57 PM

Here's what I found out, in verbatim....

Quote:

they may physically fit, I belive they're the same size as the 7mge ones, which should be the same size as 5mge ones, which should be the same size as 4age ones. From there you will have to continue that flow of logic as my 4a knowledge is limited. However, the 7mgte injectors are never used in an M engine NA setups as the resistence values it puts out are on a different scale, and thus the clips are different sizes. If this friend is going with a stand alone enginemanagement system then that shouldn't be problem. But if not he'd have to play with some resistors and really know his stuff to make the 7mgte injectors work. And yes I belive the 430cc/min spec is correct for them. Unless hes going really crazy though the 295cc 7mge injectors might be a better choice. Much easier to get working and probably adequete flow. The 5mgte and 6mgte guys who use them all run a little on the rich side with around the stock 7 pounds of boost. Most of them would love to find a set of 240cc/min injectors that drop right in (this exist in some jdm toyota engine, thus very hard to find).

damn, Aaron, you got good hook ups yo! :P Thanks for the help, I emailed vortech about the FMU to see if it needs to be reclaibrated after awhile, and I will change my fuel filter tonite. I really hope its the filter, and not the FMU or inline pump, cause that shiat cost bling bling.

hey 4AFE...just a suggestion.

i'm not sure if you do this or not..but it's a good idea especially on the resources-rich www.

hunt down a few more hardcore toyota forums / mailing list..and post questions on there as well.

never hurts to have more opinion

http://pub25.ezboard.com/bdorikaze these guys are from the west coast..along with a few east siders

toyota-mods is another good one. it's email based, and there are a LOT of knowledgeable people on there.

4Aaron GE · 09-19-2002, 02:43 PM

hey Lafora, is the TM list still around? I stopped recieveing stuff from them a few months ago....

Lafora · 09-19-2002, 09:42 PM

yah they are..i get a few everyday
