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.

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!!

      (it is a brand new ported mellings pump) I suspect the lack of pressure is due to the leak. It was *not* that low in other logs of oil pressure in the past. It wasn't that hot either, but not far off.

      Would a Mellings oil pump be a viable option  From my time with a LS, and talking to tuners and LS specialists, the "weak" OEM oil pump is one of the first things they recommend to swap out if I was going to give the engine any high RPM I opted for a Mellings high volume, with the high pressure springs and I never had a issue with it Cost wise they are not expensive in the scheme of things

      By davemoto63 · Posted

      Just bought a 2002 Stagea 250tRS VR-X Four AERO VQ25DET and spent the last two weekends cleaning and detailing it.. still have to do the wheels and the engine bay but the rest of it came up nice. Imported 2011 to S.A. and I'm the third owner since it was imported. I met the guy who brought it over, he went to Japan and picked out the car, bought it and ordered the wheels. He also gave me a list of stuff he did to the car with receipts. Coil overs (I have the original springs), 3" exhaust from the dump pipe back no cat, Custom dump pipe,(I have the original exhaust), Plenum spacer, 18" custom Work XSA wheels (need restoring, I've made a start..), Shift kit put through the 5 speed tiptronic auto, TV and menus/screens changed to english, Australian DTV tuner installed in rear. I've just had four new discs and new pads as well as all the fluids including the brake fluid replaced. I have all the receipts for the last 15 years and the import papers in a nice folder. Car looks great, goes like hell but fuel economy is not a thing lol.. pics next..

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      I ended up in this rut again lol, and used a shit ton of filler. One thing I can't understand is, even after using a big long block and going in long X pattern strokes, I always end up at bare metal again with no filler, and my repair started at one end of the door and now I've chased my tail to almost the other end of the door. I was thinking of hitting the panel with a hammer where it might be a high spot and making everything low then filling it, I did this on a small section on my other door by mistake and I think I fixed it lol. Is this a bad idea? The other thing is with guidecoat, whether it's the powder or spray, after I sand all the guide coat off, it doesn't reveal anything for me in terms of high spots and low spots and makes it especially hard when it's bare metal (at least in powdered form), am I doing something wrong here, or likely a high spot I keep going over and creating valleys? Lastly, stupid question but, is it possible that after sanding if I only sand over the filler area where I know to be a dent that it's impossible for me to dig into that dent? Unless there are other problems which I missed.
