What else is needed with aftermarket Turbo?
Newbie question...
I have an '05 Sti on the way. I'm planning on getting a "Turbo-back", "fuel pump", and a "tune". If I added, say, a "Green" (or other similar turbo) to the mix, what else would be needed? I'm really looking for a nice setup that I can put on all at once that with tied me over for a while...

you might need a larger intercooler.

yes you will need larger injectors, a FMIC, and some sort of EM for your "tune"...prolly a boost controller as well...and an intake that would work with your FMIC piping...in the end, it really depends on wut your planning on getting out of your setup...

Larger injectors are a must. Don't forget about new oil lines for your turbo. If your new turbo has water cooling then you might need longer water lines. The bigger IC is a good idea so you can get the max out of your new turbo. Even if you don't do an IC or you do a bigger TMIC you will need a longer 90 degree silicon hose. And the three items you mentioned earlier (TBE, pump and EM).

a turbo inlet hose is also recommended, as the stock one can break rather easily

aside from the turbo, you'll need some bigger injectors, fuel pump, tbe, intake, em, larger ic, custom tune, maybe some fuel rails, headers/upipe, big MAF, turbo inlet...to do it right you'll need $5000-$6000. Sorry to drop the bomb, but it's not an easy/inexpensive upgrade. Good luck!
Can anyone clarify if upgraded fuel rails are necessary for a green conversion??? How about header/upipe? Thanks! |

My question was: I'll have TBE, it will be dyno tuned, with fuel pump. If I got a Green, what else do I HAVE to get. I think the question was answered correctly by a few above though. |

Once you get your STi, let us know how the turbo upgrade goes.

Don't you need a larger IC for a larger turbo? Won't it overheat?
(I am a newbie) |

I tend to do things the right way from the start. You're dealing with an STi, not a civic or mustang. I have over $8000 in aftermarket parts on my STi, all of which has come from deep research. By the way, I've made one of the fastest 1/8 runs in the country with the stock VF39 at 8.04 at 84.5mph with a 1.64 60ft. Last edited by burnin4; 11-15-2004 at 10:43 PM. |

You don't NEED much of anything for a turbo upgrade, unless you actually want to use it to it's potential. My question is how do you get a 'tune' if you don't specify getting any sort of EM. IMO everything starts with good EM. Other things that will be needed to get the most out of a Green are injectors and a fuel pump. Everything else is a constriction still, but at least with injectors and a fuel pump, the gas can keep up with the air.
I am still really curious on people's opinions on the value of fuel rails. They sound like a very worthwhile upgrade along with the other fuel stuff, but not everyone seems to mention them. offset |

I don't doubt that if I bought everything under the sun for the STi that I can make it a killer car. Please understand what I'm asking rather than spouting some little kid sayings "get you some of that". Come on. If you don't mind, please bow out of this thread, I'm really interested in other peoples opinions rather than arguing with you (as you don't truly understand my question anyway). Thanks for the info you've given... |

The only things you NEED (as ive said before) are fuel pump, injectors and engine management... screw NEEDING "big maf, fmic, fuel rails blah blah blah. Dont get me wrong, those additions would definately up the antee. But not a neccessity.
Adam EDIT: allong with the TBE |

you ask for valuable advice, and then turn it down when you don't like what you hear. I might have gone a little too in debth for you, but I was making an effort to provide you with details. Go ahead and try to get by without some of the debatable needed parts I mentioned (em, larger IC, intake, fuel rails, headers, ect), but you are playing with a much more sensative beast compared to the traditional rwd V8 that only needs exhaust, cam, and gears to go fast.
I do apologize for my rash comment. However you should spend more time researching the countless opinions already posted instead of dismissing them without any logic. |

Right on the fact that you don't NEED headers, big MAF, fmic (they definitely would help though, but aren't a necessity). However, spend the money on a UTEC or Hydra or you will be wasting your time. You simply won't get much out of the turbo without good engine management and tuning + the fuel stuff. JIMHO. Take it or leave it.

I agree on your Hydra assessment. It isn't available yet, but I've talked to enough people to know that it is the engine management I want to use when I do my turbo upgrade (it will be available prior to my purchase of a new turbo). I will sell my AccessPort at that point. AP is a good product, just not flexible enough for my needs.
Regarding the original post in this string - I think engine management should be one of the first mods for the STi so it should definitely be in his package of goodies if he is trying to make power from a new turbo. Again, JIMHO. |

I managed to piece together a setup that includes a GT35R w/ custom downpipe, external 38mm tial wastegate, uppipe, larger MAF, header, TurboXS FMIC(new one), PE 850cc injectors, and a tuned Ecutek reflash for ~$4500 with 1,000 miles on all the parts or less...so I would hardly consider $8,000 a reasonable figure. After selling my stock VF39, stock TMIC, and stock injectors it came out to a ~$3600 package. Had I gotten everything new and kept my stock parts it would've been closer to a $6,000 package so I don't really see where you're get $8,000 from.
