The factory Starlet blow-off/recirculation valve was not going to fit in the new engine bay layout so I purchased a Turbosmart (Kompact series http://www.turbosmart.com.au/products/kompact-series-bovs-bpvs) blow off valve. The Kompact series valves are a nice smaller size primarily designed to replace OEM valves and I chose a universal plumb back (full recirculating) valve with no venting to the atmosphere, a 25mm outlet size (options are 20mm, 25mm, 34mm). Because the BOV is mounted close to the airbox, I'll probably hear the "pshhhht" air venting through the nearby pod filter but I wanted to retain the legality of a non-venting BOV.
The BOV is mounted between the two intakes pipes before and after the turbo (standard fitting for any BOV) and it fitted neatly in the engine bay. I used a 25mm/1" steel pipe and after cutting a hole in the appropriate locations of the main intake pipes, welded on a small length of the on each intake pipe and fitted the BOV with some 25mm radiator hose. The vaccum hose from the top of the BOV will be routed to one of the intake manifold vacuum hose outlets.
And yes, I am aware that the Turbosmart BOV is installed with the ports the wrong way around when I took the photos.
