B6 Audi A4 1.8T build, turbo choices??

[Infamous1.8T]

Hey there! New to the group and am looking for a little help!

I've owned my b6 a4 now since 2014 and last winter my AMB head cracked and since then I've rebuilt the motor. I got the block hot tanked and powder coated, polished the crank and bought forged H rods and forged wiesco pistons. I purchased an AEB head and using stock cams got the motor assembled by a third party.
The motor is not back in my car now, I have a manual 02x and I purchased a stage 4 clutchmasters clutch and single mass flywheel. this is where I'm at as I'm not sure which route to take so audizine community help me out!
I've done some reading and looking online and I've came up with a few options for turbos
GT3071?
GT2871r eliminator ?
GT28RS?
Franken turbo f21?
K04 015?

My plan is to use the car as a weekend warrior or summer driver but I still wanna be able to drive it to and from work. Pump gas 94 93 or 91 octane
Somewhere between 300-400hp would be nice

What's gonna be the best bang for my buck and what other supporting mods are mandatory and what can I add down the road to save cost?
Manifold?
FMIC?
WHAT SIZE INJECTORS?
FUEL PUMP?
MAF? OR LESS?

also what am I gonna be looking at for tuning?
As much info as possible to help me make up my mind is appreciated!
Thanks everyone!

28RS or 2871 will get you to your goals and be a great streetcar. I’d use Motoza for the tuning. You’ll need 550-1k injectors depending on what fuel you plan to run.

next gen GTX turbos are now available in the eliminator setup from ATP

I read somewhere that the 440 green giants would be good choice and I can source some for cheap l, what do you think?

I’ve got a used set I’ll sell 100

Skip those, old tech. Bosch EV14 is what you want at a minimum. Very affordable.

Go w a GTX2867 Gen2 they make an eliminator form of this and if you crave more power you can swap the exhaust housing and run either a t3 log style manifold or if you wanna spend big bucks a top mount tubular manifold. Can also mix in a set of cams like IE.

K04-015/ hybrid k04s like the frankenturbo won't meet your power goals because they don't have the top-end flow. Won't be able to make any meaningful use of the bigger intake runners on the AEB heads with small frame turbos like these that are mostly all midrange.

You already have rods which is the first weak point when upgrading turbos so you have many options. Like others have stated a newer gtx28 class turbo would give you good spool and good top end.

550cc EV14's at minimum, if you're looking to do over 300hp you're going to need a fuel pump. I have major issues with the stock pump not keeping up in the 300hp range and I'm only on 91. If you want to run e85 in the future I'd just get the 1000cc injectors.

Do a T3 flange if you can. You'll get bored with the elim after awhile and you'll be sad when you have to basically start over with your build.

A 2871 or 3076 gen 2 is a good place to start. if you insist on an elim definitely get the newer ATP gen 2's. I think 2867 is the only option though. the older versions are pretty much undrivable below 4k RPM's due to the old tech in the turbo's paired with the restriction from the elim housing.

FMIC: the ER sport is good to 400hp, get the comp for anything bigger.
