B5 S4 ko4 turbo upgrade

[BOO$TedS4]

Alright guys, yes I have searched threads and I haven't gotten what I'm looking for. First off my car is a 2001 S4 I have turboback exhaust, sillyrabbit smics, vast meth injection, ecs coil packs, stock injectors, and built internals. So my questions are what size injectors should I get for running 91 with the ko4s and what all am I going to need to upgrade to those turbos? Bigger fuel pump as well? Also is there anyway to swap turbos without pulling the motor. Any help is appreciated, thanks :)

I think you just asked the single easiest question to search for. The car is 16 years old. Do you REALLY believe nobody has ever asked or discussed the topic you're inquiring about?

Stop being lazy and start reading. It'll only make your setup better as you learn more from all the countless build/discussion threads out there

Depends on the tune. Every off the shelf tune as well as in dependent tuners will use different injector sizes for tunes. Some of the common ones are green tops, green giant (I have brand new ones for sale $200 PM me), Bosch ev14. They will come in different volumes (CC's/lbs).

Likewise for other hardware requirements, it really depends on the tuner. You could get away with running stock fuel pump, but it's not too expensive for a piece of mind. Common pumps are walbro 450 and Bosch 044.

Common MAF housings will be any 85mm housing that your (you'll most likely need a hitachi MAF sensor if you are a 2000 car) hitachi sensor will bolt into. Then you'll need an accordion hose that will fit the stock y pipe. 034 has all of this stuff.

But when it comes down to it, A tuner should be able to tune around your hardware and not the other way around. But, an experienced one should tell you which hardware they recommend. Pm me if you have any more questions.

Really not necessary to respond this way. Regardless of how you feel.

It most certainly is necessary.

A lot of people (myself included) use the search function, with great success, when needing help or trying to learn something new. Unfortunately people like the OP clutter this forum with useless threads such as this one which only makes it harder for other users to find the information they're looking for.

Agreed

Not everyone is well experienced like some of you. Be humble and accommodating and not asserting authority.

Well said.

I tried my F21 car with the stock fuel pump, made it about 2 days before it just couldn't keep up.

Yes, you will need a fuel pump.

As to this guy below, freedom of speech only protects you from the government. Mods here could censor you or even ban you for whatever reason they wanted.

That's all.

I think his point was instead of being like the other people be more like you.
