Need help, Pre-planning Build (500whp)

tomasp001 · 02-18-2020, 09:26 AM

Greetings all,

I recently got my first vehicle, an '08 E90 335i AT Trans as a daily driver. Need help planning my build. I am currently still on the maintenance phase as the old owner neglected this car. Bought at 128k kms. GOAL = 500whp (limitation cause of my trans and reliability reasons). Please let me know what I need to upgrade (turbos, HPFP, LPFP, etc) to get to my goal reliably

What's been done:

New Batt (coded and registered)
Brand New Index 12 injectors.
New coils, New plugs (2-step colder)
New gaskets, (Oil filter housing[was sweating], Intake manifold, Valve cover)
Walnut blasted
New Trans pan with new Trans fluid. (was sweating)
New oil (Liqui Moly 5W-40)
New power steering fluid.
New rear ball joint and lower rearward control arm (was squeaking)

Purchased and waiting on "500hp N54 kit" from BMS with BMS OCC and BOV throttlebody adapter.
Purchased and waiting on VRSF Catless DP and Street exhaust.

There are some limitations that I will list here for my build.

1. No e85. (Canada, no e85 at pump) (idk whether meth injection either at port or throttlebody or race gas is better/cheaper)
2. Reliability.
3. Comfort features must stay (as it is my daily driver, that means no weight reduction as I need my rear seats.)

Congrats on the new car!
500whp on stock turbos is going to very hard. I'm fbo with meth and only making 427whp. You will need aftermarket turbos for 500whp reliably.

Where in Canada? E85 is a thing in some places.

Intake, Big intercooler, Chargepipe, Pure turbos and inlets should be good to go

You could have a little fun before changing turbos. Charge pipe, catless DP, dual cone intakes and a stage 2+ tune(I'm using MHD) and you'll be into M3 territory.

My buddy has an S4 with a MP90 supercharger on it and I pull on him. N54 has potential with minor upgrades.
