Milenko2121 Posted April 2, 2013 Share Posted April 2, 2013 I've been searching on google and this website for a week now, and I can not find what plug I need for the EGR. if anyone could help out that'd be awesome. Quote Link to comment Share on other sites More sharing options...
NewZed Posted April 2, 2013 Share Posted April 2, 2013 Pretty sure that an M16 bolt with a notch ground in to the side will self-cut its own threads in to the inside of the pipe on the exhaust manifold. If you can't get the threaded portion out (I couldn't) and ended up breaking the pipe off. Might help if that's what you're talking about...

Milenko2121 Posted April 2, 2013 Author Share Posted April 2, 2013 I'm doing a turbo swap into my 280z, and I got the MSA downpipe which has no EGR hook up. I made an EGR block off plate for the top, but now I'm trying to figure out what size plug I need for the bottom. Quote Link to comment Share on other sites More sharing options...
NewZed Posted April 2, 2013 Share Posted April 2, 2013 You might take another look at the EGR device. On a 1978 N47 manfiold once you block the top with a plate, the bottom ports don't matter anymore, unless the passages are rusted through. You only have to worry about the exhaust manifold supply line from the exhaust manifold, which you don't have. The turbo system could be different, I've not seen one up close.

Milenko2121 Posted April 2, 2013 Author Share Posted April 2, 2013 i'm pretty sure it would cause a vacuum leak. either way, I just need to know what the thread size is of the intake side of the piping so that I can order a plug. Quote Link to comment Share on other sites More sharing options...
