That's is a set of tgv deleted tgv's and precision 120 lbs/hr injectors. Not pictured are steel braided lines, an fittings and a Fjo injector driver. Just need to install the parts and drive down to the nearest E85 pump and fill up. Gonna be nice to run a race gas tune on the street with high boost. What do you guys think? I hope the injectors are big enough for my setup. If not I can raise fp an extra 10 psi to 15 psi.

[mr.cat]

nice good luck with the build

[StreetRX7]

Good luck .. Take pic....

[3tc power]

holy pictures Batman!

[vimassive]

Pictures of car or at least engine would be nice.

[De O]

What cc injectors is that?

[fastblueufo]

1250cc

[De O]

1250cc

Might need some of those where you get those from we are looking into the tvg deletes to.

[fastblueufo]

You can buy them all day long on ebay.

More eBay parts.. You can do 10s also.. :))...

[cruzan7m]

:rofl:

[cruzan7m]

Good luck with the upgrades!

[cruzan7m]

I need to start sourcing parts from ebay!

[De O]

Ok cool we just got a turbo off of there and we dam near got everything else for that car off of there to.

[VIZuki]

just be careful when shopping ebay cause there are alot of ebay garbage that you hear about..turbos going bad too early or electronics failing..least you can get warranty on shop bought items you have 30 days with ebay buddys. Unless its a shop also sourcing thru ebay.

Glad the build is coming along excited to see it from stock up..down pipe will help alot..

That can be bad for max'd injectors and isn't the answer to flow of the injectors..if there bigger than the stock 380cc then you'll be fine..those are probably the size of STI pinks which I think are 550cc which is good for upgraded to say maxing the stock 06 turbo. Get 850cc if you plan on bigger turbo or E85..Once built block is thrown in going with 750cc and call it a day..E85 good luck finding it but if you do have fun with it. Meth injection is also just as equal in cost. Think E85 is a bit expensive.

[De O]

Well we looking 1000cc plug and play Dr Zuiki

Moooor pics. Coming along just fine. I do need to buy a fpr. I have a set of plug and play sti top feed injectors that are cut and modified to 850cc I will sell or trade. They just came off my car. There are 3 E85 stations around town. Its 3.16 a gallon. A lot cheaper than 6 a gallon for race gas. The most I put down on race fuel was 480 on a dynojet. Same gas and tune I put down 430 on a dyno dynamics in New Orleans a few months back. Prol the dyno dynamics was closer to true numbers.

[fastblueufo]

What do you all think about the new piping color?

Bright but nice .. Lol.. Coming out nice an most importantly clean an neat .. :bowdown:

[De O]

Nice

[92vr4]

Yea, i never like buying anything from ebay. Especially for my car. But she look good, except for that neon green pipe.

Lol well, I didn't buy the injectors off ebay. I just said you can buy them all day long on ebay. They are precision which are a brand name and not some cheapo from vietnam lol.
The lime green is pretty toned down if you see it in the day light. It has some ultra fine dark gold metal flake added and give the green a kinda bling factor. Didn't know if I liked it at first but its growing on me. Stands out with the car and intake being black.

[mr.cat]

nice

[fastblueufo]

About 95% done with the install. I loaded in a starter rom and it fired right up. Just waiting on the carbon fiber alternator cover.

Looking real nice.

I'm trying t ofigure out another method to roatating the charger volute so flow can be increased try to limit down the amount of bends myself..that looks like 3 1/4 inch piping? damn thats alot of flow..got your TB ported and spaced? I'm trying to see what's needed for this did the TB coolant delete and intake manifold coolant delete here in the caribbean not needed and intake charge is 1-2 degrees higher than ambient air..

I have 2.5" from turbo to intercooler. 2.5 from intercooler up till it comes back through the fender wall and into the engine bay. Then 3 1/4 from there to the throttle body. The throttle body is a v7 off a jdm 2.0 sti. I wanted to do the coolant delete but I have my turbo water cooled.

[mitsusqueeshee]

Is that how those hoses going to stay? I would try to route them in a way thats more tucked away, maybe even build some hard lines and try to look more OEM style....just my opinion. :rolleyes:

[fastblueufo]

Yea I know what you mean about a shit load of hoses. Wish subaru would have cut down on that use. I plan on tucking them down off the top of the motor at a later date. Just have to get a plan together before I do it.. got any suggestions or ideas?

[VIZuki]

none..other than a v mount which some people use which routes piping at top but also rotates your TB which would include having to buy a whole nother manifold... :-( but in the end response is key..most don't realize where dealing with cars that have potential but Subaru stands by being as safe for the ENVIRO so they pull alot back..well at least stock..lol I think my biggest issue is flow not so much throttle cause my blower always has me near boost but lag still happens with centrifugals..especially as big...I want repsonse

[mitsusqueeshee]

I would try to route those fuel hoses low, and everything towards the back of the motor. Nothing strewn around the top of the motor. You get a hose caught in that alternator belt and look out.:eek: The best way would be to bend some sections of hard line, or maybe use some 90's or U -AN fittings to route both pressure side and return to the back. Also use some tie downs in a few places, just got to study how the factory does things, and emulate that using some creativity.

[fastblueufo]

That's o good idea! Run everything around behind the motor. I will need some u-an fittings. I still have about 15ft of 8an fuel line so that should be plenty. Gonna be a few minutes on the an fittings, those things are not cheap. I still need to tie down a few hoses and wires before I start tuning on it. I just have the fuel blocks hanging atm also. I made a bracket to bolt them to but havnt got the bolts yet. I'm going to have a few days off next weekend so I will get time to do a few things. I also have a carbon fiber alternator cover that isn't pictured, its still in the box...

[VIZuki]

tie down and tuck and you shouldn't have any loose hose issues unless you decided to cut alot of the ties already and are left with wires needing to be tied lol. alot of hoses can be eliminated by using T couplers where needed..Think I eliminated 3 hoses all together just from this so yeah like said above its more so creativity than set in stone. As for Fuel hoses don't know why Subie went with 2 fuel lines 1 return and 1 breather for wrx to my 1 fuel 1 return 1 breather..I'm assuming for proper fueling but 255's clear up that issue by alot...maybe search on eliminating the twin fuel lines to maybe into one..cause I'll be honest you no longer need it if you still have it.

[fastblueufo]

I had the 1 inline, 1 tank and 1 breather. The fuel went in one rail then out that rail and into the other rail, then back to the tank. The only problem with that is with large injectors you are running near or over the fuel pumps flow when running E85. That causes a pressure difference between the first rail and the second rail. The stock line that feeds the second rail is pretty small.

I ran parallel lines to feed each rail. That way both rails retain the same flow and pressure. I probably went overkill on that since I'm using 8an fuel line but I was going to have to run from one rail to the other anyway so I just went parallel also. I've been eyeing the new airomotive 340 pump. I wonder if its loud like most airomotive pumps? If its quieter than twin walbros in the tank I might go for it.

[fastblueufo]

So i finished the install and flashed my base rom. she fired right up and idled like stock. I tuned the injectors on 93 and drove it a few days till I felt comfortable I didn't have any fuel leaks.

Ran the tank out and filled up with E85. Made a few changes to my rom and she fired up on E. I started tuning and I must say this fuel is great. I don't know why I even had my knock detection unit out. The car is making about 30 more hp as my 93 tune on the same boost. I was able to add a few * of timing.

My only problem now is my fuel pump. My pressure drops at 6k rpm and 24 psi. My idc and afr also shoot up so I'm stuck at a moddest 21 psi atm, at least until I can upgrade my fuel system. Thinking about twin wally's in the tank. Or a 044 inline with the intank pump. I need something that is going to flow around 300 lph at 83 psi line pressure. I know the 044 will fall a little short but I can go over 300 lph if I use a boost a pump to increase voltage to the pump.

What are your thoughts or ideas on a fuel system?

[Want3d]

Dual Walbro's run real good. I've seen them used on evos with the fp black and holds up nice.

I have been hearing some good things about a pump company named Fuelab that makes fuel pumps. Supposedly they can be controlled (I think the controller ties into the ECU if you have a fuel injected engine like yours otherwise there is some sort of separate box if running a carb) so they are not running as hard for everyday driving which should add life and reduce noise. They make pumps for both carbureted and injected applications. Priced in line with Aeromotove etc. A company called Titan is a dealer for them or you might be able to buy direct.

I think your parallel fuel lines to the rails makes sense. I have also read that the return line from the regulator wants to be sized to match the feed line, probably as once it leaves the regulator it is low pressure. The last might be more applicable to a bypass regulator feeding a carburetor.

With E85 you are needing about 30% more fuel so I am not surprised you are running out of pump capacity.

Are you having any problems getting it up to operating temperature with the E85?

I have no trouble getting up to temp. It rises like normal. Sometimes it will have to turn over a few more times than normal to crank when the engine is cold. But then sometimes it fires right up. I have noticed that it doesn't like a lean afr like 12.0 gas calibrated. But it loves the afr to be in the low 11's. I can throw all the timing that I want at it at that afr. But, once afr gets higher than 11.8 on my wideband it will get finicky with the amount of timing it will take.

Something else that I noted was that if I ran my afr gauge showing low 10's I wouldn't lose power. Power remained pretty much the same from low 10's to around 11.7. I would actually lose power at a leaner afr because I had to reduce timing. So leaner really isn't meaner from my short experience with tuning on this fuel.

I did tune a 2010 wrx stage two on this fuel back in october. It liked a lean afr and a lot of timing and boost on the stock turbo. Guess when your setup gets to putting out 400 whp and up that the leaner afr is not that good of an idea. At least on my setup. But my setup never had any trouble running a leaner afr on race gas. But I'm sure the race gas probably had a higher octane.

[VIZuki]

lean or rich lol isnt a closer ratio to a whole going to be equal to 1 so are u saying your adding or removing

[De O]

I think he said that he was running it richer on the vege juice cause he can run more timing than on pump gas.

[fastblueufo]

If your tuning a subaru 12.0 is lean LOL rofl

[VIZuki]

I think he said that he was running it richer on the vege juice cause he can run more timing than on pump gas.
:rofl: thats what I figured he was talkin bout lol from stoshed. advanced timing??? anyways I know what you mean now..we always called it that or the guys at surgeline at least...;)
I hear timing can get pulled in the double digits on subies:squint: uumm thats alot of loss especially if un-standalone(reflash,OS,tuned) cause now the puter doesn't want to advance and this can last upwards of 5 start ups..so if you have all this undercontrol pretty damn nice cause now you have full control...still very hard to do on subies even with a standalone...:dunno:

Deathwerks came out with a new 300lph fuel pump
