dyno results in

[boo ya speed]

i havnt put in my fuel rail injectors downpipe yet they are just sitting in my car but with intake and boost guage running 12 psi i was running a little lean and 192hp and 212 lbs not bad ill post the dyno sheet soon need to get a scanner

 

[MSPDAVE125]

I'm VERY interested to hear how you leaned out enough to require a 12:1 FMU.

12:1 FMU is a huge pressure increase! 380cc are not the most common injector but are bigger than stock. And Fuel rail with more volume?

FYI your stock fuel pump won't support a 12:1 FMU....

You'll need a Wabro 255 hi pressure pump for sure.

You're trying to say that you dynoed 192/212 with just 12psi & the AEM CAI? (boom02)

No bulls*** called here! Just curious about your fueling choices!!!!

yeas i know, the vortex fmu is auto set to 12:1 ratio but im not going with that choice anymore im going with the emanage so i have full control anyways plus my computer isnt letting me go past 14 psi so with the emanage with the ignition set i will be able to overide that as well,

also i am getting that dyno sheet up as fast as i can

You will need new fuel pump and 440 injectors

 

[boo ya speed]

why 440 injectors?

 

[orangezoom]

Your stock ones will not pump enough fuel

yeah i have 380s im going to have to hard wire the harness but thats easy my fuel rail just got delayed today so i wont see it for 2-3 weeks damn canadians lost my order

Hey watch it! I'm a damn Canadian and I can make it so you're Fuel Rail is lost forever! J/K..

Yeah OE 4G63 injectors are 440cc's they are a good fit for the MSP. You can find em on Ebay for like 100.00 USD.

 

[tekkie]

Do you have bigger injectors on your MSP Dave? you need to come out to some of the toprotege meets dude

 

[MSPDAVE125]

Got'em yes... Installed? No.... Once I have the equipment to reduce the duty cycle on them.... then they'll go in...

 

[TurfBurn]

are you sure they drop in without the o-ring and all those other issues that were the problem with RX-7 injectors? and the 4g63.... is that the evo motor or one of the eclipse motors... sad since I use to be a mitusbishi guy... but it would be helpful info for people that read the thread to know for sure which car you are referring to and which engine/displacement it is... not a lot of things get listed by their engine codes unfortunately.

 

[MSPDAVE125]

As you would with any injector, you change the O-ring. But yes I believe they can drop right in.

The 4G63 has had 3 generations in North America now. 1989-1994 /1995-1999/ 2003-up EVO.

The 4G63 has been around since the mid 80's in Japan.

I beg to differ. Everyone I know talks in engine codes/ chassis codes rather than displacements/ # of cyl. Once you learn them you never forget'em!

When I said change the o-ring I was referring to needing a new size, having to have a new spacer and all the other "little" modifications that some injectors require to "drop in" on our cars. I will need new injectors this fall, so I'm searching at this time.

You also I think slightly misunderstood me on the engine/chassis codes. Most tuners and people who modify cars and are enthusiasts talk in those terms yes. But unfortunately most people on EBay and many online vendors/stores do NOT use the codes. The better ones often do, but if you go on ebay and search for 4G63 injectors you'll get far less hits than for turbo eclipse injectors... even though it is the same engine typically! That was all... but yes the codes matter a lot more and are better for terms, but for those that aren't experienced enough or are very forgetful (like me!) knowing the code and the associated car/displacment/model that it is associated is helpful!

Thanks for clearing that up though and for the good info! Might be time for me to go hunting for soe EVO injectors

 

[MSPDAVE125]

I see what you mean many sellers on EBAY are rather generic in their descriptions. Sorry for the confusion

With regards to the O-Ring. I don't think a new size is required.. It seemed snug to me.

What weird though is i've seen 2 or 3 MSP's now with different combo's of OE injectors. Like I have 2 denso and 2 Mitsu's from factory another guy had all Mitsu.

you may want to check out the EVO injectors as this is the 3rd gen 2.0L turbo(4G63) and even though it's coded the same, alot of external components were changed...

 

[TurfBurn]

I'm also hearing word that the WRX injectors will drop in without any modification. So I may have to consider that path as well. Whatever ends up being the most reasonable!

Please keep us posted. I'm also trying to research larger injectors but having a hard time keeping things straight. At one point, HiBoost was offering RC engineering injectors with spacers and some type of connector adapter. I'm really curious what was meant by connector adapter. Sounds like you plug the stock connection on one end and then into the injector on the other end without any modification. Honestly, if some vendor got on the ball and made an adapter, they could probably score some business. I would personally pay for adapters if they where good quality. *Hint*Hint* to all vendors

I still don't see any dyno sheet to disprove my skepticism.
