They look like stock 90-93 blue tops. Which are 205's.

Those have been around, they take stock injectors and modify them for certain flow

The real question is, what fuel management are you running? You can't just slap in bigger injectors and call it a day, what do you control them with?

Honetly, I seriously doubt you need 750cc injectors from your previous posts, wasn't it a T25 that you have?

I think he has a T28 now, I got his T25 this week.

Those are going to idle like crap unless they're low impedance, then sequential injection would make it even better.
Don't expect to idle those with a MSI any leaner than 12:1:1 smoothly, if even that. Even with hi-res code it will be difficult. You might get 12:1 with hi-res, the NB fuel pressure is too high for large high-z injectors greater than 550cc.

Those are Venom injectors. Go over to Rx7club.com and do a search. Absolute, utter ****.

i was looking at these cuz i'm building my engine going to be running around 350whp or so using my aem f/ic and yeah i have the t28 now... will the 550's be enough to run my set up

Not sure you can run that much safely on the F/IC, but I could be wrong. Stick to high 200's for now, I have a feeling you are destined for failure of EPIC proportions trying to achieve 350whp based on your questions.

With over 300whp, if your motor even thinks about knocking, you can say good bye compression if youre lucky, good bye rods if you're not.

well i'm going to have a fully built engine,big injectors, big fuel pump, good fpr, strong clutch, big radiator, strong tranny, and good lsd...what do you think can go wrong

mx03tb

iTrader: (1)

This is what my engine will consist of
FM valve spring kit
wiseco 9.5.1 piston
supertech performance valves
CAT rods
ARP head studs
new block with crank
tial bov
injectors??
FM dual feed fuel rail
magnector 8.5mm spark plug wires
Mybe Snow Performance W/M

wow.......not
Why 9.5:1?
Why not get all valvetrain from supertech?
Why a fuel pump, FPR, big injectors, and F/IC?

See what I mean about this being a bad idea?
I think you still have a ****-ton more to learn before you start thinking about 300+ or even 250+whp. So far you're talking out of your ***.

What Tranny do you have? I swear if you say 5spd you will die in your sleep.
What can go wrong with 350whp? I am surprised to see Darwin has not done his thing with you yet?

The nut behind the wheel.......or in this case, the guy doing the tuning. You can spend a gazillion dollars on the most exotic equipment in the world, and yet have a spectacular failure just because your spark map wasn't tuned right.

I am but a miata noob, but its safe to say you will have rods hanging outside the engine block if you make one mistake.

Another question that begs to be asked: all that fancy stuff, and still no proper engine management? WHY?

mx03tb

iTrader: (1)

i'm still working on that i figured i can have the engine running at least on the f/ic untill i get the stand alone

I would avoid those injectors. I heard from witchhunter that they flow like crap.

Ok sorry for all of my stupid comments i wasn't very sure about the things i needed for my engine build, I called supertech and they directed me to belfab, I talked to Jim and he explained everything to me and what i needed and they have a whole engine build kit for a very good price..

Savington

You need to stop posting and start reading, seriously. 350whp is not an unobtainable goal, but just throwing a bunch of expensive parts at the car is not the way to do it. Get rid of the stupid-*** piggyback, too.

+1 just get the AEM standalone period if you wanna throw money out... for 1500+ you can get damn near everyone who knows how to tune in orlando to tune that thing
