Question about Pure Stage 1 before buying it.

Has anyone here got Pure Turbo Stage 1 for 235i yet ? My current mod is Jb4, Dp, Cp, Intercooler, Michelin Pss. Before i order the stage 1 , i would like to have couple questions:

1. Is the stage 1 turbo really feel that different from FBO ? At low , mid, high range
2. The Fuel it stage 2, is it optional or a must have ? I only use E85 and 93 Ron , no meth yet

Thank you for your help guys.

Im pretty sure you only need a Fuel it stage 2, if you go stage 2 turbo..but even then I don't think its "required" per say

Stage 2 is a much more popular choice we sell a lot of that kit.
Stage 1 will be similar to stock with a bit more power and more area under the curve . It will be noticeably faster with stage 1 vs stock

Fuel it stage 2 is not required but strongly recommended.

Thank you for all the reply guys. I though the stage 1 will boost the power up around 400 to the wheels ?

JibHonk Thank you for your offer, but I like to keep the stock turbo, and will put it back when i sell the car later.

dt20011 Thanks for the reply. A bit more than 400 is what im looking for right now. For stage 2, it will cost more than 5k as i estimate , and a lot of stuffs that i need to buy . Will go to that stage latter .

You said your 235 puts down 430/440 , is that number coming from Stage 1 or Stage 2 Pure ?

My plans are JB4, DP, FMIC, LSD and Pure Turbo Stage 1. I wanna hit the race track and run on the mid 11's. From what I gather in this forum is doable.

Sound like a good plan man.What do you expect the power and torque after all of those set up. With 93ron alone, with 93 ron + E85, and with 93+85+Meth ?

Speaking of which, when would it be required? If I ran a stage 2 turbo with FBO and ran 93 octane would I need to upgrade the pump?

I'm sure you will. That's exactly why I don't wanna go with Stage 2 cause I don't wanna mess around with the fuel pump.

After all, I wanna have some fun. But this is a brand new car that cost $50K and I need the peace of mind of the warranty.

From what PURE told me I shouldn't need to swap any pump out but I'll follow up.

You don't necessarily need to swap out the pump. But when you do go stage 2, if you do, the stock fuel pump just won't be able to handle the increase over a prolonged period of time. Out of peace of mind I would just do it all at once..If you're already dropping the money on a Stage 2 turbo upgrade, you can do an upgraded FP.

Money is tight on just the turbo. May follow it up with the pump. Is that hard to swap out? Where is that pump located?

I'm 99% sure the pump is swapped through the back seat, removing the seat and accessing the fuel tank etc through there but don't quote me on that.

Honestly, i'd hold out to do FP and stage 2 turbo at the same time.

i don't see meth in your mods. You're definitely going to want to run meth for the STG 2.

Hi Guys,

Just to clear things up about Pure Stage1 vs Stage2.
If you have an EWG car, the Pure Stage1 is still a nice upgrade but won't make that big of a a difference compared to changing stock turbo to Pure Stage1 on a PWG car. The Pure Stage2 turbo is a total different animal. It requires less octane to run more boost. And also is more efficient at the same boost.

Eg. on Pure Stage1 Turbo you can manage 21 psi of boost midrange tapering to 16/17 psi at 6.5k rpm. You need either meth or E to get enough octane to run this much boost. It will get you to 430-440 whp.

On Pure Stage2 Turbo you can run 17 psi on 93 octane fuel till redline and make 450-460 whp on the stock fuel system (on F series cars, E series cars have a better HPFP to allow for more boost on the stock fuel system). With meth you can run up to 22/23 psi and make 520whp.

As for the LPFP stage2 upgrade, this won't help you as the limitation is on the HPFP side. I have a Fuel-IT Stage2 LPFP since October 2014 to see if this was the limitation. But actually this only showed my HPFP being the limiting factor.

On my stock F series fuel system I ran 17 psi on pure stage2 on straight 93 without problem. Add more boost and I see HPFP pressure drop in the logs followed by missfires due to that. Most of the time I run E20 with meth (80/20 meth/water) and this allowed me to run 22/23 psi of boost albeit I had to roll on the throttle and start around 3.5k rpm.

If you don't want to run meth you can await the Fuel-IT TB Injection kit which is a spacer with 2 highly atomizing nozzles that get fed by a solenoid that taps in the hard-to-softline before the fuel line gets to the HPFP. For this a Fuel-IT Stage2 LPFP is required as well. No more rolling on the throttle etc.

HI! !!!

Excellent explanation. I have a question Darkiedm4. My M235i has PS1 and JB4. I have this issue at mid rpms where as you can see the car tries to up.to 17 psi (Map7)but then something happens and the EWG opens.... but then... try to close again.

at the beginning I thought it could be pump gas pressure so I tried to Map5 and the issue was the same but just at 15 psi.

what do you think about this? what could be?
