what is this?

on the end of the inlet manifold

It has an electrical plug but no connection The engine is not original JX but a 1.6 td out of something else.

BOV [blow off valve]..whats the blue can and pipe work in your picture?

[boxer]

It's my home brewed breather trap. works quite well but i need to glue the elbows to the pipework and there doesn't appear to be much oil anyway.

So the BOV, It's not connected electrically to anything, is this the one I would need to disable if i wanted to increase the boost above 1.3 or something?
Or to put it another way. Can I just wind the boost up because this will protect the engine from anything more than 1.3?

'm not about to until the inter-cooler plans come together.

Ta,yes no electrical connection,and yes the bov is to stop over boost..please post about your intercooler progress[I have a Gtd intercooler that I'm trying to fit]

[boxer]

I have a choice of range rover (mounted up front) or an LR defender one which could go in the engine bay vertically across what used to be the air intake box and either rely on negative pressure in the bay or a fan. Either will be plenty big enough I think.

[dave friday]

You probably know that a front mounted intercooler will have a tremendous boost lag...

[boxer]

Yep. But it is a 1.6 td so not looking for massive boost just a bit more power and a lot less stress.
