Default Another Injector Question

I saw someone posting about downsizing injectors...

I am "upgrading" as it were; being broke, I have the 305cc 80's Supra injectors to replace the stock injectors. While I understand they are undersized for a Super 16G, it's all I have...

Unless. Are most injectors the same dimensions? My now-deceased Mini Cooper S was upgraded to 380cc injectors, and I still have the original 330cc injectors lying around. Anyone have any idea if they would fit on a Miata?

you only have three things to consider;

-physical fitment; - they either fit or they don;t

-impedance [low or high]; - what does your ignition expect? does that match the injector? or some stand-alone EMS [e.g.; mega squirt] allow selection to match the injectors

-connector - purchase new connectors if needed

If you want to run any more than like 5psi on that turbo you'll need to ditch the pos poopra injectors and get at least 460cc

most bosch syles will fit. some are a bit too fat to fit down it the head recess. i recommend spending the money for deatch works 440cc with the mtune dual feed rail.

...and plug one side of the feed to save money on fittings. BatInc is cheap and has the best quality fittings of anyone I've used.

680cc, what the hell do you need that for, its not exactly a 800hp monster, friend.

well ok, instead of a 440 with dual feed, just do a 700cc with factory ****. your bound to wind up with tons of fuel in it.

it seems your info my good sir it a typical ebay mistake. goodday.

Plug the FPR and convert. I just switched mine for simplicity.

You will only make little over 300hp with 680cc/min. That is still a lot. But no 800hp. Use google and enter "injector calculator". Those tools are quite accurate.

I'm pretty sure the Mini Cooper injectors will be a little shorter than the Miata injectors. ...and they will have a different electrical connector.

330cc injectors will only get you to around 200hp before you'd run out of injector.

We have new 350cc, 450cc, and 600cc injector sets that are drop-in fitment for your engine for only $339.

We have an easy to use calculator page on our website: www.deatschwerks.com/fuel-calculators/
