Need photos of stock a injector from the VR-4s. Just want to compare them to other brands.
Cheers,

96-97 Mitsubishi Legnum VR-4 Type-S
will post some when I get home.....
As promised
Thanks Dave :thumb1:
My phone for some reasons can't upload pictures (as of this morning) to my PC...
So what are they? High or Low impendance?
Anybody knows of a goog upgrade?
Anybody upgraded yet?
FTO guys in Australia got 720 cc for their 6a13 engines...
... and the FWD Galant from TW has SARD 550 cc injectors in it.
SARD injectors do indeed look very similar to ours!
Well i know the injectors used in the 1996 GSR 1.8l are the same as ours. I've jumped on the Lancer Reg forum and asked if the 560cc injectors (EVO6) will fit the GSR 1.8, that way we'll know if we can just use them.
At the moment none has replied
I've seen the injectors from 1st generation of VR4 (4g63 - 450 cc) they differ from ours.
I know that dannyboyau (at www.ftoaustralia.com) or FTOLTD (at this forum) is running larger sized injectors on his 6a13 engined FTO. 590cc?

"hi folks
just a little update
should get the clutch back on monday then it will be just a few days till it should be back on the road, will post a few new pics later in the week of the twin plate clutch, solid engine mounts, titanium wipers, DBA gold rotors, engine cover, 590cc injectors and the melted piston "
"finnally got my injectors and they have been tested to 940 cc at 90 psi, mmmm lots of fuel couple more minor things to do to the fuel system, so there should be plenty of fuel for when we get the clutch sorted, just need to get this other motor built so we can push the boost right up. MMMMMMMMMMM cant wait ((( damn this clutch ))) "
"hi everybody
i get a emails asking about the conversion, usually asking the same type of questions,
Could you post any questions here as it will save me answering the same question several times, and will benefit anyone else who is interested.
Cheers "
I was unable to get registered at FTO forum, so if this offer is still valid...can you answer some questions here?
PS: ? And Jeff (from same forum www.ftoaustralia.com) got 760cc?
This info is on from site(http://www.uq.net.au/whocares/FTO.html):
4. Fuel System. A walbrough 1000hp fuel pump and upgrading all 6 injectors to msd 850cc. & SX fuel reg.
yea sure i can answer any questions, the new motor is in have had it handle over 26 Lb boost. I have also made some custom fuel rails to suit the bigger injectors. If you are going to run bigger injectors you need to be able to map the fuel, so aftermarket computer or piggy back computer is needed.
What do you want to know
Everything!!!
But I guess we should only type one question at a time...
What injectors have you upgraded to?
What's your turbo flow rate(cfm, lb/min)?
Why have you melted a piston? Leaned out or is 400 hp mark kind of too much for stock pistons? Btw I am still confused with the numbers here, is it WHP or BHP?
Why did you have to modify your crank sensor?
Opps... :-D too many questions already.
Well, with outside temperatures holding in -30s C (for a second week), I have plenty of time to come up with new ones. Stay tuned

790cc , they are 10mm longer so i have made fuel rails to suit and also have made bigger spacers so that they can be used with the original fuel rails.Originally Posted by valmes

The turbo is a GT30 Garrett ballbearing and is roughly rated at 500 Hp the flow rates depend on the boost and efficency of your setup.
I can only speculate on why i melted the piston, It could have been a bad batch of fuel, could have leaned out. I can definately say that it was caused by detonation, there can be several reasons for detonation, the most common is poor tuning. The two motors that i detonated pistons on were tuned each time with in a week of them detonating. I no longer use this tuner and will never use him again, just incase it was his tuning that caused it.
I ran the stock pistons at 18 Lb boost for almost a year, that was around 400 Hp @ the wheels
I had to modify the crank sensor to suit the computer we used.
What brand of injectors are u using? Got any photos of them?
Do have any photos of ur custom and factory fuel rails and spaces with the injectors installed?
Cheers,
Rhys
Anyone got the actual part number of the standard Mitsy injectors for the VR4 ?
Ta
MD319793
Injector Kit, thats all the bits with the injector like the o'rings and a couple of other ring things that go with it.
Rhys
FTOLTD thanks for your answers!
If you can answer just one more...
I guess it is the same question that came from -LegnumVR4-...
...790 cc? Who produces them? Which company? (Low Hi Imp?)
When are you going to try timing it(your turbo FTO) on 402m?

Well... they don't seem to be willing to share that information...
From what I found - our injectors should be similar to those from GTO (though they use smaller 360 cc/2 nozzles/top feed/low imp ones... ours are 390/4 nozzles/top feed/low imp??).
GTO/3000GT Stock injector
Upgrading injectors 3S style...
SARD or MSD... well any brand I guess that has injectors of similar dimensions and specifications... and of course with needed flow (cc).
One more interesting link:
Try it! It shows how much our stock injectors can handle. Just dont forget to change initial values...
Having got the multimeter out and read a resistance of 14.8ohms I would say our injectors are high impedance? I have read that low impedance ones are of the order of 2ohms.
Dont quote me on that though :rolleyes5
Most Mitsubishi Turbo Cars come with stock low imp injectors.... and NA ones come with high imp.
Why 8G Legnum/Galant should be any different?
Can anybody sort this out? :rolleyes5
Athough not specific to the VR4 it does give a lot of info on the sister car the 3000GT.........
Injectors
Funny... now we're posting same links...
Contacted RPW, they might know what we have...
...and here is another link:
"Takakaira.com" List of injectors upgrades available to other cars...
"CD5A [evo 1-3 shape] lancer GSR injectors 390cc top feed low impedence
CM5A [95 onwards (evo 4 shape)] lancer GSR injectors ???cc top feed high impedence. "
above info came from here:
If information, that 1996 EVO GSR 1.8(4G93T/CM5A) injector is the same as in 8G VR-4, then we have an answer - high imp!
So this should fit our cars prefectly, since I saw some of the GSR guys going for it as an upgrade (see link to Takakaira.com above). Have to verify it though...:
550cc Injector; Skyline HCR32 RB20DET; Connector type - Angle; # of Nozzels - 1; High imp; Price - ¥12000 US$111
Most Turbo Toyota injectors would also fit the bill, with some modifications to connector...

I would share it if i could, but the supplier wont say who the manufacturer is and even has gone to the point of scraping the numbers off the injectors. They are high impedence.
I can deffinately say that the 6A13 TT engine injectors are nothing like the GTO injectors.
I did try and find out who made the injectors that are in our engines, i was in contact with bosch in germany by email and phone they could not identify them. They are made under licence to bosch ( common practice as bosch holds the patent ) I did get some information that suggests that a japanese company by the name of JECS made the 6A13 TT injectors.
The biggest problem is that the 6A13 TT injectors are only about 56mm long and are very short compared to normal injectors, i did find some short ones at 550cc but are still too small for my needs.
i will take some photos of the injectors and fuel rails but need to remove them from the car, so please dont hold your breath as i wont be taking them out to take photos. next time i am performing work and the manifold needs to come off i will take them out and photograph them.GTO/3000GT Stock injector
