I've been dribbling a fair bit recently about installing bigger injectors in our fuel rails. Finding injectors weren't easy becuase of "trade secrets" surrounding what can be purchased off the shelf. When i went to my fabricator and got talking about what to use, he open a draw and pulled out an injector that fitted straight into the rail and manifold no questions asked! i was so happy to see this yet so pissed at the run around i had received from workshops and performance shops telling me nothing fits or big mods were needed to make them fit.
The injectors are an OEM injector from a Toyota 7M-GTE and are 440cc compared to our 275cc which are standard in our cars. They are however 10mm taller than those little yellow bastards found in the magna so bigger dowels had to be made. 45 minutes on the lathe and we were done!
Next problem! once both rails were raised 10mm each side, the pissy little tube that joins the two was too big and kinked as soon as i tried to bend it to suit. The pipe was cut off and the fittings that bolt onto the rail were machined smooth so a thread could be welded on. I then picked up some braided line and two 45's from Motorsport Connections here in Sydney and i was done! All i am waiting on is my Sard fuel reg which should be here monday or tuesday.

NIIIICE that look sweet mate

looks good,so is the impendance of the new injectors the same as the old ones?,also would it be worthwhile having twin fuel rails so each bank is independent of the other (seperate fuel rail,FPR,return lines) or would it be overkill in this situation?

probably overkill and yes impedence is the same

Very nice TZABOY :drool: :thumbsup:

Excuse my lack of mechanical genius-ness, but would these only be beneficial for those like yourself with wild mods & forced induction, or would they also benefit a stock Magna engine or something like the common AMC first base level (simple mods like exhaust and K&N).
...or would it only offer benefits if the car had one or more of the following as well...
- Larger fuel pump/Fuel Pressure Regulator
- Piggyback ECU
- Extractors
- Different cams
- etc.

I guess I'm just asking (for those like me that have no idea), what else would the engine need, before a mod such as this would become beneficial. Thanks.

good questions

This is a mod for when the car needs more fuel. Going bigger boost obviously requires more fuel to match so thats when a mod like this is needed. For example, if the stock injectors were near maxxed out with no engine mods, then going bigger injectors would be needed if u went cams, higher comp etc. For an N/A car with just bolt on's i doubt its needed.

With the blower or turbos, and with Turbo cars runnig more boost than factory. More air requires more fuel. So bigger injectors are used to keep the fuel air ratio's good.


Jas its good to see more quailty stuff from Road Runner and JMR

and even better to see the the p00 motor is good for something else

yeah, only decent part of the 7M are the injectors haha.

Jase at JMR and Lindon at Roadrunner have been so helpful, best part being they let me do most of the work and running around, they just do the harder stuff and point me in the right direction

Top Job :thumbsup:

Even forgetting things like... Need, Performance, Reliability, etc.
Just appearance alone, it's a sweet looking piece. :cool:

Good work.

It reminds me of the Commodore blokes using the Blue 2.6 magna injectors on their engines.

looks good, i like shiney things :D
did you just use spacers to rase up the rails? thats what those round black things are right? :confused:
also are you still using the standed rails or have you got wider ones?

Looks mint mate, congratulations!

they're the same rail but the end fittings into the braided line were drilled out to suit the new ID of the thread that was welded on. The spacers were made out of a rod of acetal and turned on a lathe to give the same dimensions except 10mm higher

that is the poo jase. i love it.!!:D

Looks good Jase, very similar to my setup, except my injectors are green, my fuel rail spacers are metal (and not quite that tall judging by the pics), and my braided line between the two rails is shorter with 90 degree fittings on each end.

i couldn't use 90 degree bends because i have the base plate for my supercharger in the way.

also on another note, with the standard setup in my car atm there is less than 5mm clearence between the top of the rear rail and the bottom of the s/c. what i now plan to do is get my old plenium (which will never see use on my car again) and cut the mating plate off where it joins to the intake manifold. Once its cut off, machine it to 10mm thickness and space the whole s/c 10mm higher. when its all apart i'll have to go and purchase 10mm longer bolts :P

looks good mate nice job how much did it cost you????

Look's the shiznit bro! Flash one !!!!

Okay - didn't realise the blower was that close to the end of the fuel rail.

How will you go with bonnet clearance after spacing the blower another 10mm higher? Obviously you've measured it up and know it's gonna work, but I was under the impression there wasn't much clearance between the blower and the bonnet.

there is bugger all clearence. if worst comes to worse i'll throw some spacer blocks under the hinges of the bonnet but that is worst case. Its gotta be done so we'll sort something out lol

bonnet scoop maybe? should keep ya blower cool aswel:)

did magna's ever have problems with fuel starvation, with the turn around fuel rails? having fuel flow in 1 end and out the other? i know the purpose of a FPR and i guess of the pump is up to the job there wouldnt be an issue, just a few inline 6cylidner guys have due entry fuel feeds with a single return.

Subies have a feed to each rail (being 2 separate fuel rails like the magnas) with an FPR on a line that connects from both retun ends of the rails, basically a Y feed in a Y feed out, instead of fuel in one end, past all 6 injectors and back out again. or 4 in the case of the subarus. I heard this was easier to prevent fuel starvation, and have more lineal afr's between cylinders.

when you are going forced injection, fuel needs to be spot on with heat and pressure involved

I'm not an expert on the inside of a WRX engine bay - infact I don't think I've ever taken any notice of one, but being a horizontally opposed engine - I'm assuming that the two fuel rails would be a fair distance apart - hence individual feeds/returns on the fuel rails would be necessary from a design point of view.

What you're describing makes sense and is probably the optimal design- but I don't think it's really going to make a big difference. We're talking about magnas after all, even out of all the guys going down the forced induction path - are probably only 2 cars in the country that have put out more than 350hp at the wheels with these engine.

Nicely done. Is anyone suprised that there is a whole lot of reluctance from tuners to divulge the secrets of those stupidly priced aftermarket injectors :nuts:

Kudos for the work done here, now everyone can piss off that silly 7th injector and go with a greddy to mind the injectors :) Very cool. Greddy emangle also has a map sensor input too, and auxilliary drive for water injection (PWM control).

I'm working on a translater for the PWM control to run a 240V (very high) pressure pump for water injection - 350psi plus. Small and quiet too, and found in your old coffee maker :)

Think aquamist quality and proportional control for very little $$$

there is bugger all clearence. if worst comes to worse i'll throw some spacer blocks under the hinges of the bonnet but that is worst case. Its gotta be done so we'll sort something out lol

that looks pretty lol. love how your car is coming up man. really love it.

also regarding clearance issues what if you were to get a bonnet bulge??? not something massive like tha BA bulge just something a bit mure subtle that would look neater then having washers under the hinges

but all in all love your car and the work you have put into it.

nice work Jase.

wrt to the bonnet clearance issues, I'm in the same boat. the heat mat on the underside of my bonnet is actually rubbing against the top of the blower. unfortunately it's right where the cross reinforcements are, so there's not much cutting you can do.

cheers,
.wook

yeah it sux! might just cut a square hole in the bonnet and make a "shaker", at least i'll have reason to unlike those new BA/BF FPV's running around with fake shakers on their cars.

1st off i'll be making some spacers, might have to make myself a carbon bonnet down the track

That would be a nice addition

Nice job on the fuel rail,Sorry to hear about the height problem hope it is not to hard to sort out,And not to hard on the wallet

Latest addition to my fuel system setup, a Sard Fuel Presure Regulator :cool:


http://img182.imageshack.us/img182/8949/1001135ol2.jpg

I'll be locating it on my water/meth tank (where the battery currently lives) next to my oil catch can. I might get a gauge for it for added bling but we'll wait and see

Nice reg.. they are good.. i got one..:)

If you dont mind me asking, wot the injectors cost you, and how much would labour be ?

labour? i have no idea because i'm doing it all myself at a mates fabrication shop, he's just making all the new alloy bits and pieces next wknd! woohoo!! i scored the injectors 2nd hand off a mates old engine for 150 bucks, then had them cleaned so $300 for a set of 6 injectors and they're out of a toyota 7M-GTE

bit of an update, the car is getting ripped apart next friday night and will spend the wknd getting all the mods made and its booked in at SAS for a new ecu the following monday, just in time for MM08 (touch wood)

Fuel rail is in the car! had 2 very very late nights on the car but she's nearly ready for her big tow truck ride down to the tuner. Lucky i pulled the charger off in all honesty, i had severed the oil return line from the charger to the main return line so she was leaking a little bit of oil, all sorted now of course

quick question where did you get the intake made im looking at getting one like that

cheers Brad

A mate who is a fabricator has made that up for me, he is also making my water/meth tank. I'm pretty sure any decent exhaust shop will make one for you, or you can just buy my old plastic K&N pipe

awesome. bet you cant wait till shes all tuend up and running again.

lol man how many times have you pulled that charger on and off, should be able to do it with your eyes closed lol

haha last night it took around 45 minutes from putting the base plate on the intake manifold to putting the belt on finished, and about 10 minutes of that was cursing the 7th injector while i tried to install that, pain in the **** of a spot!

or you can just buy my old plastic K&N pipe

shoot me a PM interested and a pic if you have one

Thanks Brad

install and tune of a new chiptorque XEDE was supposed to be done yesterday and today, but i have been told they sent the wrong unit so will be done tomorrow (i thought dealers kept stock in the bottow draw???). Not even going to guess what power it'll make, but as long as its safer and more driveable i'll be happy.

No word on water/meth injection kit but it cant be too far away. The holding tank for the mix has been fabricated and is in the car with the battery now in the boot. I'll make a new thread once i get the results tomorrow

you know its been 38 miniutes into the next day and yet you havent posted anything up (bit slack)

top effort on you car tza its one very very very nice ride it really is great, reading these threads is great

Been told the right ecu still hasnt arrived as they musy have missed the overnight transport. not impressed and a little worried as wakefield park is friday and i dont want to miss that!
