BMW AH3 N55 335i F30 512 WHP 526 lb-fts 1/4 mile 10.917 sec

How to modify AH3 N55 335i F30 to have 512 WHP 526 lb-fts 1/4 mile 10.917 sec?

Please give an idea:
HPFP, LPFP, PI, bootmod3 custom tune, e20,e85, upgrade turbo, meth

Car installing Dorch stage 2 + pure turbo stage + E20 or

Pure turbo stage + fuel it lpfp stage 2 + PI + E20 achieve my target? or I need to run full e85 and meth injection (I think it's not practical for daily use)

Please advice.

You will need a pure stage 2 turbo, upgraded hpfp (dorch stage 2), lpfp, down pipe, charge pipe, E40-50. Shouldn't need PI.

You can do it for 6k if you can diy some of the install.

What wehee126 said for mods. Though a lpfp may not be needed for those power levels unless you choose PI over hpfp. Also will need a tune like MHD/BM3/JB4 and a race intercooler.

If you don't have easy access to e85 you will need meth.

Correct except no LPFP needed for E40-50 and add IC (bigger than a 5'' stepped) as noted above, and custom tune. BM3 OTS stage 2+ might get you close without a custom tune, assuming that works for AH3.

While you are upgrading the turbo you probably also want to do turbo inlet and DV like turbosmart. Stock intake and exhaust are fine.

Why issues with running meth on a daily? I do it just fine.

There are no specific issues so long as your tune is made for it (if you run OTS tunes you rely on fuel trims to compensate). But if OP has access to ethanol and upgrades the HPFP, that is a simpler solution for additional octane and fueling.

I'd say go speedtech turbo kit. You'll need supporting mods of course but you'll get there little by little and supports 100% oem fitment for everything. You will need to upgrade fueling to take advantage of the turbo, but the hard part would be done for you.
