[Jacky]

what would be the best option to get 450 hp in my audi s2?

[s2dk]

gtx 3071 gen 2 or 3076 gen 2 or something around there

...depending on the periperhy of the engine...
GTX3071 GENII is capable for 600 HP on the I5, dending on cams, manifold etc
You need to gi a little bit into detail:

How much moneye are you willing to spend :-)

450 hp at the wheels is my hp target too (ABY) and I've been thinking the following:

RE85
9,5:1 CR pistons
FCP X-beam conrods
GTX 3071 gen2
RS2 Evo exhaust manifold
Stock intake manifold
Wagner IC
Stock cams
Stock head
Big enough injectors (need to consult tuner for exact cc)
3" exhaust
1,8T coilmod with R8 red coils

That's my list. Based on my research this should get you at least near the 450 hp goal (at the wheels). I might have forgotten something but hope that helps

I have
wagner exhaust manifold
collector of adminision BST
siemens deka 630cc injectors
steel rods
series pistons
I would like a turbo that works well in low and high revolutions

I have the SQ em, reverse inlet Wagner, larger intercooler than Wagner, stock pistons and h beam rods, I use the 3071 gen2 at 2bar and make 400whp with nothing more to give. I have the 0.63ar though to allow for fast spool. If you use the 1.01ar you will get a lot more lag but possibly reach the 450whp. However as you are using a high compression ratio as I do, you will be knock limited unless you use e85 in which case you will probably do more than 450

I bet Issam, aka @Wizard-of-OD can hook you up or help point you in the right direction.
