so...anyone know whos idea it was that supra 315cc injectors become 360cc in our cars?
after doing a little research, i noticed that our FP and the na supra fp is the same, its the TURBO that has a lower fp.  this means that those injectors are only good for about 192hp or so @ 100% duty cycle..ill have the printout from RC Engineering scanned into the 'puter and put it up here in a day or so. i think without a FMU, some of us will be running real close to the edge thinking we're safe.. gee, and we wonder why theres all these dead 5sfte's out there  cant be THAT simple, can it guys?? itchy, if what im thinking is true, man your REAAAALLLY close... is anyone running a fmu? if so which? hmmmm

You can say that again, wait you did.
The turbo injectors, arent they 440's like the 3s's? The FP is lower because its a bigger injector. Now IDK what you guys are using to turbo your 5s but if the 7mge injectors fit why not use the 7mgte injectors? Do the 3s injectors fit? -------------------- |

They is most likely aftermarket injectors for the 7mgte so get those and try those.

Could always try adding an additional injector and having a seperate controller for it.

ok guys after checking this all out again, it seems the intial formula that i got from someone on the mr2 board wasnt correct.
the formula goes like this: injector size 315cc=30lbs per hr X 3.2(80%duty cycleXnumber of cylinders)=96 X .61(brake specific fuel consumtion)=58.56hp per cylinder X 4 =234.24 flywheel hp THIS MATH IS WRONG!!!!! so thats what we're "safe" up to. after that, who knows..lol the formula was taken from rc engineering's tech section, so i trust that. sorry for gettin on ya shid.. just like to try and keep the posts helpful its that rule that mamma always taught me, "if you dont have anything good to say, dont say anything at all"  :::EDIT:::chris D from celicatech posted the correct was to do this math. here it is. You need: (Inj. Size)*(duty cycle) / (BSFC) = HP/cylinder (30lb/hr)*(0.8) / (0.61) = 39.344 * 4 cylinders = 157hp Reported numbers higher than this very likely have a duty cycle higher than this. If you use 100%: (30lb/hr)*(1.0) / (0.61) = 49.18 * 4 cylinders = 197hp This also assumes that the base fuel pressure is 42psi or whatever the 315's are rated at.

what about the 2jzge? They MAY have a higher cc rating. As for the first person who said 360......well its been a while but.
Years ago when Nuke first started the 5sfTe trend into the celica world he along with many other celica and MR2 owners never could find out the exact #'s. Some sites said 315 some said 360. Most old topics did say there was confusion in the cc rating and both terms were used. I guess over the past 3ish years people either went with 315 or 360. Id find one of Nukes old quotes from c.net but the site has been cleared. -------------------- Member of Team 5sfTe

ok guys i couldnt get the printout from rc scanned, so i just took a pic of it..here it is. before cleaning in the left column, after in the right...
as you can see, even at a bsfc of .50, we're gonna REALLY be pushing it..so i go back to my original statement. we're gettting DANGEROUSLY close to the edge with these injectors..  heres a pic of the collection so far, exaust mani. elbow & cat are missing from the pic, theyre at moms for test fitting on the old engine.  ...just a few more things..hehe
