Thread: Boost takeoff point on Inlet manifold

If it's de-EGR'd

Yes it is de-EGR’d but the pipe wall is too thin to tap a thread hence the reason why I’ll be drilling the manifold.

you can drill in the EGR pipe and use a rivnut in it

Peronally, I would be putting the boost point in the De-Egr'd Inlet thingy before I even considered drilling and tapping the inlet manifold.
I got mine modified whilst I was doing the EGR Removal many years ago, just had a small block of ally welded to the neck, and tapped that.

Another option, which I have used with great success, is a motorbike valve stem. Driill hole, insert, nip up the nuts and afix your hose!

Ah! - i like it (the valve stem idea)

Thanks for all the suggestions, i am however committed to drilling the manifold having only recently purchased the hardware and tools specific to the job. I thought it would have been a common mod - it seems not!

If you've got everything required , remove the de-egr intake pipe , stuff a lint free rag down the inlet, drill close to the edge of the intake face , bearing in mind you or someone else may want to refit the acoustic cover, use a vacuum to catch the filings if you can, onebobs your uncle

thats the way I did mine. I also got some sticky gaffa tape and sort of rolled it on itself so the sticky side was up and stuffed that in ontop. that managed to catch a lot of the filings. I also dipped my tap in grease so the swarth held onto the tap. then I periodically cleaned it. and reapplied the grease.

Nothing has blown up yet
