You never said how many miles and condition car is in. Expect to pay 1000 anytime anything breaks for labor and parts. Often times it will be 2k or more a pop.

For bolt ons, vrsf fmic and dp are a great value and fit properly. Get your mhd tune, and then your done. You should also do a cp, er or vrsf is also fine.

Always walnut blast first. If you doubt me and you're handy with tools pull your intake manifold off and look at the valves.

Walnut blast made my car a different car [totally stock 08]. I'll be adding a charge pipe next. Yes Walnut Blast first.

Don't bother with the DCI.
Don't bother with Stg2.

1. Stage 2 Fuel Pump $400
2. Catless Downpipes $300
3. Custom e60 tune $400
These alone will net 400+whp

4. 7.5" intercooler $600
5. Inlets/Outlets $350
These can get you in the ballpark of 500whp depending on retune and quality of engine/turbos.

When chargepipe breaks or IATs get too hot, then upgrade those items.

As everyone else has pointed out, this assumes maintenance items have been addressed (plugs/coils/hpfp/ofhg/cooling system/fuel sending unit/turbo seals/walnut blast/injectors)

I'm not sure if you missed the point or what but he wasn't asking if you had cash/card he was asking if you had MONEY in general because these cars aren't cheap.

Well money is not the issue for me.

Now I only have standard twin turbos, will those do or what kind of upgrades for the turbos I should grt

[Mata1015]

I found out my fuel pump has a leak. Could I install the stage 2 fuel instead of getting a new stock one or do I need to get the stock first

[mc335i]

Stock turbos will be able to handle the mods everyone else is stating. Upgraded twins aren't necessary to reach your goal of 420whp. Stage 2 lpfp is necessary to run higher amounts of ethanol higher than e30.

Would I have to get a new stock fuel pump or does the stage 2 fuel pump will replace it. Bc my original has a leak and I need to get a new one. So I'm trying to figure that out

I'm sorry, but until you are living on your own, have an emergency fund of 6 months living expenses, a fully funded 401k and/or Roth ira, then the money should be an issue for you.

These guys are serious and really are trying to help you. I am also not poking at you, just being honest. This rabbit hole is going to cost a lot more than you expect. And a lot of people cant keep up with it, same thing many people do with houses.

I understand but the reason I said money is not an issue bc I live with my parents and they are giving me 3 grand to work on my car. Yeah I know I sound like I'm getting baby but I have my own for it too and I don't have bills. So I don't need to worry about that those things until I get out of college. Like I said money won't be an issue for me at all. I can afford 2 grand on my own for my car

Ok just making sure. Sounds like you understand the situation. Enjoy having a faster car than most of your friends, including that buddy with the challenger.

Alright man. Anyway you know by any chance the answer of my question. I have a leak in my fuel pump I just found out and was wondering should I go ahead and put the stage two fuel pump for it now or that doesn't work like that. Or Would i have to put the stock fuel pump first with the stage 2 FP.

My understanding is it depends on what you purchase or what you are going for. I havent done one on this platform personally, but i have on my truck. Basically you are lookng for a drop in replacement, which i believe the stage 2s for this application typically are. For example fuel-it stage 2 you can choose the option for them to supply a new pump then you dont have to worry about anything.

What makes you think you have a leak in your fuel pump? If it was really leaking you'd have some serious problems.

Stop going there. They will take all your money and you'll still have a stock car and things will probably still be broken.

To answer your latest 2 questions:

Upgraded turbos: If you have money to burn, why not? But you don't need them. I've seen people crack 500rwhp on stock turbos so...

Stage 2 Pump: Yes, do it.

Are 3" cat less down pipes good enough and what's a good brand for the stage two fuel pump

Ok, like you told us, did you also tell them that money is not an issue for you, eh, did you? They will tell you lots of lovely things about your car, buddy You can put college aside until you solve all these tough car problems.

Not trying to be a dick, but this forum has a plethora of the information you seek. And on top of that, it's all been beaten to death about 5 million times. Just do some research and then ask the questions you're still unsure of. Build your car the way you want, not how everybody of the forum tells you to.

But in a nutshell, you will easily spend over $2k in maintenance of index 12 injectors, coils, plugs, gaskets, valve cover, water pump, etc. That's considering you are able to do the work yourself which sounds like is not the case. If you are gonna need to pay for labor, that could nearly double. Wish you the best of luck dude. These N54s are not for the feint of heart, but like mentioned before, can be very rewarding.
