Recirculating the HKS SSQV - Who has done this?

[FarShark]

Hey Folks,

Before I begin, I dont want this to turn into a debate about using BOVs etc. I am well aware of all the advantages/disadvantages of recirculation, vent to atmosphere and no BOVs so I would appreciate it if we just stuck to the info I am looking for

I have a pair of older HKS SSQVs (or whatever they were called then). HKS sells the recirculation fittings for the valves in 3 different sizes, the largest being 29mm OD fitting, for a 29 mm ID recirculation hose.

The inner diameter of the Y-Pipe for the two recirculation lines on the Y-side for the BNR32 is ~35mm ID and ~38 OD.

So the questions are:

1. Has anyone recirculated the HKS BOVs through the stock Y-Pipe?
2.If so, how did you do it? (i.e. Pipe sizing etc.)

I know I can make it work by using a smaller OD piping as a gasket for the HKS fitting, but wanted to know if anyone had done it a cleaner way.

Thanks

Well, I'm going ahead with this, so Ill document it and share.

Very interested to see how this is done

So the fitting went in fine. The issue I have now is clearance.

It looks like once the Y-Pipe goes in, Im not going to have room to fit hoses. Pics to come, and another thread once its all done.

Does anyone have a picture of the normal setup or the Y-Pipe in place?

Im interested on seeing how this will end as well.

Good news and bad news.

In order to make the HKS valves recirc, you cant use the stock Y-pipe, you have to get a smaller (shorter) one custom made, which I did.

However I decided to ditch the custom made piece and the HKS and go with different BOVs that fit onto the stock Y-Pipe. Therefore I wont be writing up a DIY on it because I never actually went through with the HKS valves.

Ill post pics sometime next week of the custom piece.
