PWG to EWG Conversion
Out of nothing but pure curiosity, what exactly would a PWG to EWG conversion require? I am sure many will say it cannot be done but after seeing virtually everything that cannot be done, well, being done, it obviously could.
Obvious changes would be: 1) Turbo 2) Downpipe 3) Coding What other parts would be required? And as PWG Owners defend PWG and EWG Owners defend EWG, can anyone who has had both on a F30 platform (maybe car was hit and totalled) give a realistic comparison of how much a difference there really is? Again, not looking to do it. Just really curious what it would entail and at the end of the day how much difference it would really make. |

There are obviously totalled F3x that are parted out so I would imagine Parts really would not be an issue. Again, just trying to layout what it would involve for not much more than curiosity sake at the moment and really how much difference it REALLY makes. |

For the time and money you would perhaps just be better off going with a stage1 pure turbo (895.00) before going through switching and purchasing a whole ewg setup plus labor. Or spend 2500.00 plus and get ps2

No reason to defend or argue Pwg vs. Ewg--seems like the real difference comes into play when a tune such as a jb4 is involved and e85. Based on what I have read, an Ewg car can produce more power and use less e85.

EWG compressor exducer is 67mm. Most stage 1s are 67mm +/- 1mm. Pure don't publish their specs so they're the tricky one. Pure Stg1 looks like 2mm bigger inducer than EWG. I'd consider that within the variance to call "pretty much". I sure as hell wouldn't go to the effort to "upgrade" an EWG turbo to it. Pure even said themselves in another forum that it's be a pretty pointless upgrade from EWG. |

why you would want to do this? there's plenty of N55 stage1 turbos on the market with compressor wheel a bit bigger than stock ewg, there's even stage1 turbos with compressor and turbine wheels modified e.g. TTE460 (https://www.mlperformance.co.uk/prod...nt=40438284628). And every turbo is plug&play. You can go for stage2 turbo like pure stage2 but if you're on stock fuelling, probably its not worth it as you will have ~1k rpm later spool, while stage1 turbos spool up exactly as fast as stock ones.

EWG is much easier to tune, and control of EWG is much more precise. Useful if you want to tune PID quite aggressively.
TBH I don't think EWG conversion is useful unless you are also converting to EU6 injector setup, and HPFP upgrade

most important things are turbine and compressor wheels, no matter easier or not, stock ewg turbo will never ever be able run boost levels of e.g. pure stage 2 pwg.

How are the EU6 injectors better? Do you know of any other differences between EU5 and EU6 besides DME, Turbo, downpipe and injectors? |

vacuum pump is different also, pwg has extra vacuum lines as they're needed for turbocharger control, solenoid for control. about hpfp - everyone is talking that pwg hpfp holds better than ewg hpfp, ok no go to realoem and check part number. the same hpfp pump goes to late E series (when pump changed from n54 style), and the same hpfp goes to M2 ) why it holds e85 better on pwg then? because pwg turbo cannot make boost similar to ewg so way less fuel flow needed, so you can add lots of e85 and still not crash your pump.

I really do appreciate all the responses, but somewhere this train went off the tracks, as they say.
I realize that a Stage 2 will do more than a Stage 1....and the Stage 1 Turbo isn’t that much different than EWG etc, etc, etc However, the key from reading every other thread on the forum similar to this is that PWG just doesn’t have the precise control to make and control the boost that the EWG has. That in reality was why I asked the original question about conversion from PWG to EWG. Even if someone wanted to over compensate with a Stage 2 Turbo, from everything I have read, EWG would out perform. Ditto E85 and HPFP and everything else mentioned here Thus my original post. Could it be done, what would be involved and in Performance reality, how much difference is there in the real world? I know if someone wanted to squeak every last drop of Performance out of a system what has to be done. But what if someone didn’t want to go over the top to Stage 2 and E85. Just in the Stage 1 area. Could it be done and how much difference is there in reality? Thanks. |

For a pwg car ,like the op has ,a stag 1 would be the ticket I am saying power and dollar wise vs changing the whole entire manifold just to have an ewg turbo. Isn’t the EWG turbo bigger than a PWG turbo? If that’s the case I’d rather spend 895.00 vs buying and paying to find/install an Entire EWG setup ,which will exceed the price of just swapping out the PWG compressor housing and chra with comp and turbine wheel out. More economical IMOP.

there is no point converting pwg to ewg. stage1 turbo will give 250-300mbar (4-4.5psi) more after 5500rpms where stock pwg turbo is going down quickly, you will be able to have 15.5-16psi @ 6000rpm while you can have only 11-12psi there now. If that is not enough you should go for a stage2 turbo.
