Not sure if you are aware but the GReddy RS BOV has different diam. attachments that you can use for legal plumb backs and then a vent to atmosphere for track or spirited driving sessions

I wouldn't put an RS on a GTR though. too small.

Get the Type R, it won't be hard to plumb it back in. I'm pretty sure you can get an attachment for it too to plumb it in, but any competent mechanic could make one for you. The Type R is a good bov.

I was under the impression the RS was designed to flow the same as the R (race) but keep a similar size of the S (street), thus the name RS.

Having said that I know the the RS is 40mm valve size compared to that of the R's 47mm, so of course the R will support higher boost pressures (i.e. 2bar+).

I've also read unofficial statements saying that the R should only be used for applications of more than 375hp.

I guess the best thing is that they all use the same 2 bolt flange so it's very easy to change over and check the differences they make.

I'd be going the route of 2nd hand replacements

You'll save half, if not more over the after market items, they always pop up in for sale too

The type R comes in a soft and a 'hard' spring, the harder one being for cars running more then a bar. They are a good, simple piece of kit.

As for cost, you'd be better going second hand replacements imo. Type R is $200, but the kit that makes it a bolt up affair add's on top.
