Hi,

Just bought a R33 GTSt, I am upgrading the intercooler and piping and need to know what size bloe of valve adapter i need

on the piping.

What is the best BOV for a 33 gtst, 25mm, 32mm or 38mm?

This is the kit for the cooler and piping.

I heard that if you stagger the sizes (4 in total, each one smaller than the last) makes the best "zuuuuutututu" sound.

Also helps free up about 150rwkw.

ZTUTUTUTUTUTUTU.

This is the advice :)

Or use a single GTR BOV

either/or is fine.

+1. I used to run a GTR BOV when I first got my gts-t.

I now run a Turbosmart dual port plumbed back... Apparently good for 40psi.. Which is good because I'm looking at running quite a bit out of a EFR eventually.

When they get sorted, anyway >.<

just leave the stock one on there..... there is no reason to change it

Looks like my FFP piping kit, it was cheaper and easier to weld the adapter than it was to source the flange for the stock on, and my stock one leaked... So there is occasionally a reason to change them :P

Mr no BOV man!!

Serious note, doesn't really matter if you're not smashing much boost down the motor, most if not all guys make about 300 or so use the stock one or nothing.

Cool, thanks for the help, another quick question, would a straight 3" pipe from the dump loose too much pressure? or will i need to add in a muffler etc keeping in mind its for track use and will not be registered

It's track, straight through, side pipe..... Go nuts!!

    • I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!  
    • Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out
    • I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.
    • I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?
    • I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
