Pressure just posted the Turbo FAQ links, which made me realized I hadn't completed the big 5sfte post, and there's still some stuff in there that needs to be corrected, added etc.

Knowledgable minds, post that stuff here and I'll edit it in so the post can be semi complete.

just a few off the top of my head.
BIGGER INJECTORS
the 315cc supra injectors are just TOO SMALL.
-3an oil feed line w/restrictor.
at LEAST stock sized return (-10an, -12an prefered) and keep the line as straight and kink free as possible
e-manage or simalar over the SAFCII & BTM combo, MUCH better control.
and IMO the biggest thing,
PROPER TUNING!!!!!!

supra turbo injectors WILL NOT WORK.
thats a known thing.
the 315s from the NA supra is what we used to use.

Punch. you're suppose to use the 7MGE injectors not the 7MG(T)E injectors.. but anywho... how big is the 4AGE injectors? for the 5sfte you'll need at least 440cc.

I got the 7mge they did not fit... 7mge & 7mgte pulge are the same...

my 7mge's fit just fine when I test fitted em and they didn't leak or anything, are you sure you got the right kind? they should look like this



last I knew you could use these for a 5sfte project. I have seen pressure2 post that bigger is better but I am assuming that is due to his HP goals, correct me if that is wrong.. really dont wanna shell out more $ for injectors if I dont have to.

yes those are the ones the 7mgte injectors are the same pluges...
they did not fit I must have a diffrent model but the 4age injectors are the same size as the 7mge if I go bigger I will get 4agze injectors, or turnup the fuel from the FPR....

Pressure2 got 200WHP with those injectors right?
Would you say that's the most you can get without going to
the 440cc ones? What if you added a fuel pressure regulator?

please stop using those damn 315cc green tops! they are just too damn small. just look at mannys dynos to see how lean your car is with those things.

neverstop, id REALLY look @ bigger injectors, even @ low boost, you'll be on the lean side with the 315s, just search around for itchyb dyno charts for an example.
i know i was VERY lean even @ 8-9psi.

well that sucks >>

Can I ask what PSI you where running for those dynos??

I am looking to run 5-7psi max and would like to get away with just using the supra fuel pump, vortec fmu and the injectors I already have. im NOT looking for high hp outta my 5sfte... honestly dont really give a crap about how fast this car is, im really building the thing cuz im bored and have the parts to, and would like to build the cleanest/professonal/effecient 5sfte setup to date. im more concerned about keeping it running and not blowing my internals into future paperweights (blown pistons are great for that >> ). However I do respect your opinion on this pressure cuz you have done the testing/research, so if you think I will need em with my goals then I will get em >>

Thanks

never, if your using a '26, you wont be able to run 5 lbs, minimum will be 7.
that run you see there was @ 8 creeping to 9 or so in the upper rpms.

if your looking to keep your 5sfe running, then i would DEFINITELY get those injectors. the rx7's arent that expensive in the first place so y not just get them.

NEVERSTOP

#20

Okay I will get the bigger injectors.. it just kinda frustrating cuz this will be the 3rd set now of injectors I have got for this project.. and I just recently had the 315cc ones cleaned, gonna hang onto em though for now who knows might end up using them if I feel that im running too rich once everything is installed.. sounds like im not gonna be but with my luck I would get rid of em then need em >>

so exactly which injectors do I need then for the 5sfte 440cc or 460cc?? and which gen rx7? and turbo or non? part number would be great also. Are they a direct plug and play or is mods required?

Im sure there was a post all about this and the info is all there but I missed it and I have no luck with the search function on this site

Thanks

Thanks Shin!

Only other question I have is weither or not they need any mods to fit/work. Assuming they don't since nothing has been metioned.

Thanks

Edit: Also has anyone had any probs using these injectors with running too rich at idle or stop and go traffic??
