What injectors work on a z32 MAFS?

[tm_kickz]

Does anybody know what injectors will read on a Z32 Mafs if its in an SR20DET? Let me know. I have everything but the injectors.

Thank you

the maf and the injector don't really directly read each other. You should be asking what injectors will work with the sr20det ECU.

Do you just want to plug bigger injectors into the stock wiring harness, then you should probably just buy some made for your sr20det that flow enough for you HP goal.

If you want to put some other cars OEM injectors into you car I'm not sure what you'd want. you have to figure out whether your ECU need high or low impedence injectors. OEM injector clips for those OEM injectors, which means cutting up the harness.

I know if it was me i'd just get silvia upgraded injectors from a major aftermarket manufacturer. or get the ECU reprogramed for any MAF or injectors you want instead of tring to get it too work with an SAFC

the stock 370's will work fine with the Z32mafs. finding the proper settings on the afc is another story. mine is was pretty lean just using the in-out settings for the mafs. if you need bigger injectors that plug right in you could get the S15 480's(could be wrong on the exact size,but it's real close to that) you should be able to pull enough fuel out with the AFC not to run to rich. when you start doing this kinda stuff though you should really be checkin out a wideband or pay for some dyno time to make sure it's all setup right.

denso's, nismo's, all kinds of injectors, but like mr? said, it depends on ur goals really, skyline injectors too...

Well I was checking into getting some 550cc injectors and programing with the safc. I was told that you have to get that size inorder for the z32 mafs to work. I wanted to get other opinions. 550cc injectors cost about $420-600. I really dont want to spend that much.

Im shooting for about 300-380hp. Probably adding Nitrous later on.

Let me know what you guys think.

Thanks for posting

You need 550cc injectors to run the Z32 MAFS without an S-AFC.

With an S-AFC you don't need to worry about the fuel system, it converts the MAFS voltage and makes it usable by the stock system.

Thanks. This is probably a stupid question, but which way would be better as far as HP?

injectors arent going to add to ur hp numbers, but as ur hp increases u will need the injectors to keep up with all the air going into the motor, so i guess they indirectly add some power but not really.....but would u like to always be wondering if ur stockers are keeping up or be comfortable knowing that the 550's will own all that air?

[tm_kickz]

Whats good for now? I dont have much money.

how much power are you looking to get?it really depends on that. even if you keep the stock turbo, it's a good idea to change out the injectors to 444 (aftermarket) or the 480cc (S15). However, if you're planning on getting a larger turbo in the near future, I'd say go ahead and get the 550cc ones. But before you start doing anything, if you don't have one already, get a boost gauge. Also, if you're going to "tune" it, do it right. If not, save yourself and don't do it at all. BTW, the skyline ones won't fit. They're top feed.

[EazyBreazy]

they will fit though with a top feed rail

[karay240]

yea, but why waste money on a fuel rail when your goals don't require you to use one? it's just another un-needed addition that is more likely to leak than the stock one. All it does is look nicer, unless you've got very high goals in mind. Why replace something that's not broken?
