Blocking EGR and remove butterflies (1 Viewer)

[Airbornepotato]

I have been watching multiple different videos and reading online posts, pretty much all the youtube videos i have watched that saying block the EGRs exhaust side as well as the intake side, and/or blocking the vacuum lines, seems like no-one is taking about removing the butterflies. what consequence i will have to consider if i plan not remove butterflies at all?

Theirs no consequences to not removing the butterflies. Once you've blocked the EGR, soot build up becomes a thing if the past. The main butterfly does hinder air flow but most folks would notice and the difference between having the butterfly plate in and removing it is fairly minimal (unless you're running a bigger turbo, intercooler and intake where the difference becomes a lot more obvious).

Thanks for the reply mate.this gave me a huge peace of mind. I am running everything stock on my Prado.

No worries. A handy tip is once you remove the EGR pipe that goes from the exhaust manifold back to the intake, buy (or make up) a blanking plate for the EGR hole in the exhaust manifold, drill a hole in it and weld a bung in it for your EGT sensor probe. That saves you drilling the exhaust manifold to fit an EGT probe (assuming thats what you plan to do like many others do).

That's good to know.
