Hi everyone so I mentioned before deciding between a N63tu and N55 and rather just get the N55 for various reasons.

So I have had one boosted and tuned car before FBO Fiesta ST except IC and experienced bad heat soak so this time around I'd want to make sure I add a more efficient IC that can keep up with a tuned N55 looking to make 400whp+ ideally. What power number can i expect for the car to tolerate with the auto?
Because my alternate car was a charger srt so if i can match that power that would be great.

So far what I have thought of getting is IC, charge pipe, downpipe, dry cai , bm3. Anything else im missing?

Thanks in advance.

The cars im looking at are clean titles '14-'16s with ~40k with regular oil changes to have a good platform to build on

CAI won't do jack for power if you get a bolt on CAI. If you're only after power, not worth the money.

If you want to make 400+, you'll need a Pure Stage 2 turbo and the accompanying mods (upgraded diverter valves, etc)

If you are ONLY going for 400 HP, do a MHD stage 2+ with an ethonal map. That is over 400 HP and you don't have to spring for a stage 2 turbo.

I am about to do that same set up but I'm on a PWG so I'll only make 410 WHP but the years you are looking for are EWG and MHD claims 440 WHP

Or maybe these are crank HP #'s? Not sure, either way, going from 440 to 475 with a PS2 is not worth the extra money IMO. If you go PS2 then you need fuel modifications to get everything out of it that you could to make the PS2 worth it.

Bootmod3 + Charge pipe as a start

To save money and time on the install, i recommend getting the intercooler at the same time as the charge pipe

And last but not least downpipe and intake.

Those are engine crank numbers not WHP... Second PWG can't hold power past 5k~ rpms. Pure stage 2 will give him around 430ish to 440ish WHP with 93 octane plus hold power till redline so there is a huge difference. MHD 400 hp = 350-360ish WHP with E30 blend. I plan on getting to at least 550WHP by next summer.

[BimmerHausPerformance]

Makes sense, however, huge jump in cost if that matters to him. It's just that cost per HP threshold, once you get into a turbo cost goes up quite a bit and if your goal is just beyoned what a stock one could hold... is it worth it? That's up to the OP.

[ziekxq]

It is completely worth it... You can't make more than 350-360WHP and hold it till redline. You can probably add meth and get some more power out but that stock turbo at that point will fail pretty quickly. With Pure Stage 2 you can get to 550/600WHP depending on your fueling.

I remember running JB4 with 93+ 3 gallons of e85 and even than the car was slow compare to pure stage 2.

[BimmerHausPerformance]

I'm not disagreeing with you at all, but if all he wants is 400 whp, it's expensive to take a jump from a stock turbo to PS2 for the little HP gained if that is ALL you do and stop there. If you are going to do fuel etc after ps2, then, of course, that's worth it!

[ziekxq]

He is looking to make 400WHP+... So that said, pure stage 2 will fullfil his needs on stock fueling. And if he has 93 Oct available than it is about 90 to 100WHP difference which is a lot of fun to redline compare to stock turbo.

I think pure stage 2 turbo is the most "reliable" albeit most expensive option. E30 and Meth both are cheaper, but come with their own downsides. E30 is hard to find in some areas (there's pretty much only 1 E30 station in my area, and that's a 30 minute drive), and meth can make things go boom. I guess without OP telling us what resources he has available to him, such as having more money than time or easy availability to E30 stations, it's hard to say which is best.

If he lives by a costco, I'd definitely say go for pure stage 2. Costco premium is 93 octane and is substantially cheaper than most other 93 places, while being Top Tier as well.

What about the sealed AFE intake? And yes I had considered pure turbo but would it be easy to resell when im done with the car? I like easy resell and easy to pull out parts

I run shell 93 on all my cars but i have a shell e85 like 15 min away from my house that i used to run an e30 mix with my fiesta st

Basically I am looking for minimum required mods that will still keep the N55 safe at 400-450wheel will definitely be a fun daily. I just want to do the preventative mods like charge pipe and DV but if I can keep stock fueling that'll be great.

You need meth if you want 400-450whp and running turbo out of its efficiency. With prevent mods you can get around 360whp safely.

[byebyev8]

He could also go Fbo plus pure stage 1. If its rwd its a quick and easy swap that can make 400+whp

The mods i stated above? For the 360wheel?

The stage 1 is simple plug and play? Not a full kit like stage 2?
And also thats what I wanted to ask I found both s drive and x drive which is better recommended for modding potential? I don't need awd per se since im in Florida

Yeah for the mods you mentioned... Stage 1 is easy swap as turbo manifold doesn't have to come out.

There's a stage 1 turbo and a stage 2 turbo from Pure, not to be confused with off the shelf stage 1 and stage 2 tunes from folks like MHD or BM3.

Basically you need all the bolt ons like charge pipe, downpipe, FMIC, DV, and a flash tune from MHD or BM3 to get close to 400whp on the stock turbo with an E30 blend (93+e85).

You could get a Pure stage 1 turbo (lower labor cost than the stage 2 turbo) plus those same mods (including tune) and get close to 400whp on 93 without needing to mix a couple gallons of e85 at the gas station. To me, this sounds like a better idea and less hassle.

If you want to get 450 and spend a bit more in labor, get those same mods plus the Pure stage 2 turbo, and you can max out the fuel system at 450+ on 93. Don't run the PS2 turbo on any ethanol mix on the stock fuel system... upgrade that and you can get to 500+ but I've read these blocks don't really like 550ish.

From my research 600whp is the worry point. 550whp is probably safe zone for stock block.

What is your goal? You're asking for some requirements that naturally are antagonistic to each other. Not trying to be rude or anything, just letting you know what you're getting into.

Any time you start modding a car, you throw the word "safe" out the window. Nothing besides stock is really considered safe. Everything at that point increases your chances of breaking something in the power train. You're asking for safe (as in reliable I assume) mods that'll boost your power up 100-150hp while at the same time being easily reversible so you can still sell the car. You really can only pick 2 at that point.

Getting a lot more power out of the N55 isn't too difficult, it's just what you're willing to risk and what you prioritize at that point.

400 on a stock turbo even EWG is only going to peak. Running long term with high boost on your stock turbo is going to blow it up or wear it down fast. You know the rules pay to play.

If your not switching up to a PS2 you can expect peak horse maybe 330-340whp on PWG and maybe 360-370whp on EWG. PWG has a 3" outlet on the DP and EWG has a 4".

You'll peak around 5k and drop fast with diminishing power over 6500k.

On my PWG I can peg it to redline and it keeps power.

The problem for us is air and fuel. We can we can fix the air problem but more importantly not so much the fueling. I'm not talking about the LPFP fueling but the high pressure fueling. If you have the old continental like me the solution seems to be the Helix HPFP Overdrive. Though I've not tested it yet I'm monitoring people who are and the results have been fantastic. If your stock and add the Helix overdrive HPFP it seems 400whp is plausible. If you have mods 500whp also seems plausible with the right tune of course.
