i could not find a clear answer in the search, seemed to be difference in opinion--is it absolutely necessary to get an E-manage system(or something like it) or do a fuel return line when building a custom turbo setup? can i just get new injectors?

either way, if you replace the injectors you will need to modify your fuel rail to fit them.

an emanage, with return, and larger injectors would be the best way to go. you need a shop to modify your fuel rail to allow for longer than stock injectors.

but, if all i do is replace injectors, no return line, emanage or any of that, will i be restricted to just a couple pounds of boost?

If you want bigger injectors, it's not as simple as just "replacing them". There are still no for sure answers about what injectors will be direct replacements on our cars. Some that have been suggested however are the Si (EP3) injectors, which are about 300+ cc's and then there are the STi injectors which are 500+ cc's. With 500cc's you'll need a system that can trim the fuel down enough to get you to idle properly.

And no, the emanage is not absolutely necessary. Most people that use it use it because of the timing retard option. These are usually people that have opted not to go with the alcohol injection system.

DO a little more research and you'll be able to decide. But neither the return conversion, nor the e-manage are absolutely necessary. There are other options.

speedracerchk you own lol...

she's 100% correct. Im switchin from the VAFC2 to the emanage because of the ignition option alone lol

would a moded fuel rail and injectors be all i need to deliver the right amount of fuel. i want to run like 8 lbs boost.

 
Rep Power: 326

if your looking to do all that for 8lbs of boost just save yourself the trouble and buy the SF fuel system seperate... it's tuned for up to 12psi on stock injectors.

8psi is a walk in the park for that thing, and it takes about 20 min to install

I'd be curious to know what the fuel pressure going into the injectors is at 8 PSI on that kit.....remember, the higher the boost, the more psi you will need in the FMU.....high fuel pressures are not uncommon in a setup like this, and the stock pump / injectors / seals are going to complain eventually....just some advice....

I'd recommend some type of fuel management. Like an AFC, an FMU, a stand alone, or an e-manage.

aight thanks, ive just decided to boost in the last few days, been doin a lot of research. this should help.

oh one more question. if i try to boost before i get the fuel system, and just run a few psi until i can afford a vascII of safcII, can the plastic intake manifold handle it?

i think i am going with vafcII, and i read on this site that old passat injectors are 330 cc and fit in our rails with slight modification. anyone of you got vafcII, did you get it tuned at a shop and how much did it cost to have it tuned.

u SHOW ME THOSE INJECTORS in our car - with modification that can be done by ne one . not a shop.

search for passat injectors and go to the thread started by that says HTOWNBOY . "if your looking for bigger injectors..."

Has anyone seen the Aeromotive DFMU? I think I might end up using this. From what I've read, it's really easy to program.

H-townboy has been buisy at SpeedFetish. I have seen his car. he is running the passat injectors and fuel rail.. He just had to put a spacer in to modify the fuel rail to fit.

A spacer can fix anything.

He is running a SAFC2 to adjust the fuel alittle. He is running a Vortec FMU on stock retrunless system. He is pushing 7-8psi and running good.

He posted a instruction in a past thread. Just do a search.

PM him directly or do a search for speedfetish in Houston and call him up.

so the injectors do work?

Yes. You will run rich untill you tune, but yes the passat injectors w/ passat fuel rail works.

Torque King ran 14psi on stock SF kit and running pure methanol. No issues no blown head gasket. No rods thrown like baseball bats. The plastic is actually a good idea it does not get heat soaked and heat up incoming air. maybe not good for boost. But for the stock engine it is a good idea.
