Aftermarket Plumb back BOV's

[«Cyph3r»]

Hi,

Just thinking about buying an aftermarket bov but want a plum back one. My sisters 32 has one that's plumb back and sounds really good and is pretty loud from outside the car. Just wondering if anyone knows what types are available. I was thinking about plumbing a TRUST Type R BOV back in as i know these are good and work well. Anyone down this b4 and would it make any performance diff at all and do u think it would be much louder? Where would you all suggest plumbing it back in? It's for my 1JZ Toyota not my Skyline so any suggestions / help would be appreciated.

Thanks

Jamie

Type R is a pretty big BOV, rated at 600hp or there abouts. I have one plumbed back on an R33 GTS.

they dont make adaptors for R33 GTS, only GTR, so the pipework is all custom - it would be worth checking if an adaptor is available for your 1JZ.

Location usually as close as possible to the throttle body, and of course if you want to plumb it back, it needs to return before the turbo and after the AFM. Once again, you will be up for custom fabrication.

I dont know why your sisters BOV is loud, mine is pretty quiet, you can only just hear it, but then again, my pod is fully enclosed.

It most likely will be louder than the stock BOV, but not alot.

Anther option that would be cheaper is the Trust Type S, about 2/3rds the size of the type R, but still a good bov that plumbs back. I am pretty sure they make adaptors for most cars, and as the outlet is a bit smaller, it would be easier to plumb in using the existing BOV return line.
