Injector question

[Autox MSP]

what size is our stock injectors??? 440cc???

Also what injectors from other cars would fit our car?

 

[jersey_emt]

Stock is 280cc.

Actually they are 300cc at 36 psi of fuel pressure

damn how is a 300cc injector support a factory turbo ride?? even mitsubishis used 450cc on their eclipse.

I guess thats the first thing to upgrade when raising boost.

they are ok for the stock 170 HP motor. above that i would go with 440's. on stock internals you wont need anymore fuel

And you will need someting to correctly control the 440cc injectors as well.

they even used 510's on some of the gvr4's in japan. i think it has something to do with mitsubishi knowing a thing or 2 about turbos and how to give a car potential.

thanks for the info.. id been wondering about this... now if i can just find out the .ar size and wheel on the turbo... id be happy.

acctually the 3000gt, stealth and GTO in japan, always got the 360cc injector stock.....

They are high impedance 280 CC injectors in the MSP, they will hit 80% duty cycle on stock boost, right around 5500 RPMS, and level off there.

I monitored them with my HKS CAMP system for 3 months, and this is the data I got from them. The size is directly from the MSP service book. that Chojin informed me of.

so is there any information on duty cycles with increased boost?
isnt 80% pretty much maxed out?

what was this in regard to? nobody mentioned those cars...

they have been flow tested many times. They are 302cc at 36 psi.
not 280

they should be peak and hold correct.?
and thats pretty small for that motor.

i believe they are peak and hold, but i'm not 100% positive, probably 75%, but they are small. my brother's friend has a 99 vr4 and wants to buy my 450's out of my dsm, even though he's still gonna have to find 2 more

yeah all the injectors for mitsu back in the day were low impedance. they are really being phased out now.

i was thinking of buying a set of 1300cc ported injectors from a buddy of mine who owns an rx7. he bought a lot of them. not a bunch of them, but a set amount which sells for little cuz you buy a grip. he basically bought a lot of 8 and wanted to get rid of 6. i was thinking of buying but then i realized that they are WAY too big.
