Found some 1000cc injectors on eBay for reasonably cheap and was firstly wondering if anyone could tell me if there any good or not and would I need any supporting mods? I have an s13 with a ca that has an fmic, bov, stage 1 chip, rebuilt top end, bigger radiator, cold air intake, and cat back exhaust running stock boost, would I need to change anything to run these injectors?

You will need a ECU change and MAP to run injectors that big. A stage 3 chip only requires 440cc injectors.
What stage ecu would I need? And would that require supporting mods?Originally Posted by nismo

1000cc
Total overkill! What power are you looking to run??
Why the fu*k do you think you need injectors that big???
Just wanna make as much power as I can 🤷*♂️

You don't need 1000cc injectors unless you're planning a GTX30 turbo, a ton of boost and a forged engine as you're next upgrade.
If you already have a stage one chip why have you not turned the boost up already?
Wind it upto 16-17psi and have some fun.
Alright cheers, just wanted to make more power but wasn't sure where to start, I knew 1000cc would be massive but was just wondering how much work it would be to get there

Would that just require a t28 and a map?

Depends who wrote the chip. If it's Horsham developments then what you need is listed here;

If it's someone else then you need to know what they recommend. The 'chip' is written for those specific parts, any variation is wrong.
Cheers mate

4 cly, 28psi, 1000cc, turbo, 90%, gas = 458bhp.

Just fitting injectors won't make that power without a whole host of supporting mods. Fuel pump (maybe 2). FMIC. Big turbo. Pulse tuned manifold. No cat. Cams at least exhaust cam in inlet side with adjustable pulleys. Flowed head. Forged internals. After market ECU, usually requiring a MAP/temp sensor and not a 300ZX AFM.
I can't think of anyone that has exceeded 400bhp on OEM ECU.
Jez did I'm sure, he remapped the oem ecu to over 500hp iirc
Cheers man! Why not a Z32 AFM??

Z32 afm too small to match injectors.
With tuning you have to fit a package of mods that go together. One mismatched item can lead to failure of several of the others.
Stage maps are really a tuner's stages. A convenient way to move up the power stakes following a predefined package with a ready mapped chip. You can define your own package and get a custom map to suit but if the components aren't a good match for one another it won't work properly. A well balanced package will max out together with a good combination of air, fuel and spark delivery, good timing of the delivery and good cooling of the parts.

Jez's chips and tuning stages are the most commonly used.
The chips/maps themselves are good and the hardware specs are good value for money.
