I will be installing a turbo within the next 45 days, I was wondering if any damage wouldhappen if I installed an FMU early.

 

You're likely to see significant damage no matter when you install an FMU

Don't install it, sell it and get real engine management like Crome, Uberdata, Hondata, etc..

 

bandaids are bad when you need stitches....

 

So, the installation of a fuel pressure regulator will cause damage.

 

The installation, probably not, but trying to alter it without in depth knowledge of your motor's fuel system, definitely.

Besides, you said FMU, not FPR Which one are you wanting to install?

....even boosted, you can run the stock FPR and it will be a lot more efficient/reliable than aftermarket ones. You need spend a healthy chunk of change to get a good solid FPR, and imo, thats money wasted when the stocker is perfectly fine

 

I apologize for the mix up, I was talking about the FPR. I do plan to run Hondata, in the nest week I will be installing a y8 mani on my y7. For the hondata should I upgrade to a P28? And if so should I change injectors.
