More Power

Hey guys I have a decent feel of what is out there for mods, but id like to know what you guys think the best route to go is.

Currently 2016 M235i N55 with sport dp, cp, MPE, Intake, JB4 map5 with e85 mixture

my thoughts on potential options;

1. add meth... would this even help though as I will likely be close to the fueling limits with the e85 mixture...should help with timing for more power???

2. Pure stage 2... on e85 mixture seems like it would be a good bump in power, but people say to take full advantage you need to upgrade fueling

3.Pure stage 2 with additional fueling... can anyone chime in on the functions of upgrading the lpfp vs port injection...also from what I understand there is no hpfp availible for the n55 yet

4. Enzo stage 3 turbo (in development)... I am not really interested in this...atleast not yet... I want into the 400-450-500 hp range first


is it possible to run the pure stage 2 on pump/e85 mix without additional tuning? Could you go that route then upgrade fueling at a later point?

If you want serious power I highly recommend upgrading your turbo along with additional fueling. Since you have access to e85 I would skip meth and go straight to a port injection kit. Without additional fueling you'll be limited to around 16-17psi to redline with the pure stage 2 on pump gas or low ethanol mix. To really take advantage of the upgraded turbo you'll need port injection, upgraded lpfp and an n20 tmap which will allow you to run upwards of 25psi to redline.

To answer your last question, yes you could do the upgrades in stages and add the port injection down the road. Tuning wise you'll be fine with just the jb4 but at these power levels I would recommend a back end flash.

A different, faster out of the box car would be a far cheaper and less problematic solution. It will be cheaper then blowing up that $16K motor (not installed) or that $8K automatic (not installed) or that $5K 6MT (not installed). These cars can handle some serious power, but there is a risk. It would be cheaper to go out and buy C6 Z06 and call it a day. Just being honest.

Not a bad idea, but I financed new and would loose a lot on the car. Also already have a good amount of money in the mods. I think this car is perfect in just about every aspect... a little more power would be fun though.

I believe the pure stage two runs about $2500 plus install which is not an insane amount.

You can do a pure stage 2 turbo and keep the stock fuel system it would give you like 450/450 on 93. Darkiedm4 has done this and it's worked for him very well before.

Doing a stage 2 really opens doors for future mods if you get power hungry.
I did a stage1 turbo but I didn't want to spend $3000k or upwards on the 2.

That will probably be my plan on PS2. Pump gas with a small ethanol mix e20-e30 if possible. Trying to take advantage of some of the cooling properties of ethanol.

I'll run 100oct with a small ethanol mix, instead of PI and LPFP upgrade, when I want to run more boost. I assume that will get me close to a PI/LPFP setup. Anyone run the PS2 like this?

@ronanz does.
I would try running a few gallons of e85 at this point see how your car likes it. It's a strange thing but some cars like it some don't, some more some less e85.

Last year I ran 4-5 gal of e85 no issues. This year on my second mix my car HPFP flipped out. Started sounding like a type writer.

At least this way you'll somewhat know your limitations moving forward to a ps2.

On stock fueling you'll be limited to 16-17psi to redline. If you want more boost you'll need meth or pi. I recommend pi since the meth is limited to around 23psi. With pi you can push over 27psi boost although you'll likely blow your turbo at that point.

Short answer is that you need port injection to truly max out this turbo.

Any way to explain how you can run a higher boost with meth and not a fuel system upgrade? I thought meth just added a cooling property, which in turn let's you run higher boost. Wouldn't your fueling still be limit be the same with or without meth?

Random Question

Can you run a PI kit when using still pump fuel or is that pointless.
I do not have access to E85 and plan on doing a Stage 2 turbo and goodies over the winter months.

I also read someone recommending having a back of Flash on the DME.
Is this the best/only way to make the serious power for this turbo?
So do you just Flash the DME and the JB4 acts as a Boost controller for the car?

(If any of these questions are super noob or have been answered a million times dont be afraid to tell me to use the search engine lol)

For more boost you need to run fuel system upgrade. Adding E means you have to inject even more fuel so that stresses the fuel system more. After around 17-18 psi the fuel system needs help with pure stage2.

Around that you require more fuel volume you also require more octane. So a pi kit would not make sense on just 93 fuel. Better get meth instead then.

You can run a backend flash and use jb4 as boost controller.

@Op if i were you, i would skip PI for safer option in the future. There are discussions on other forums how unsafe it could be, even tho it doesnt happen a lot but it could. MMP was a victim IIRC.

Pi is much "safer" than meth.

Thanks everyone lots of good info! It sounds like though route to go would be p stage 2 then fueling later if I feel the need.

Time to do some more research on that while I save. Are there any good diy turbo installs on here? I didn't see any on the pure site.
