So when i bought my R32 GTS-T the guy told me he was only running stock boost, i had alot of questions for him and it slipped my mind to ask him how much stock boost is on the car.. Would anyone know? I've tryd to google it but it only comes up with GTR's. And how much boost is safe to run on a stock RB20DET engine? Is there any chance of me being able to wind it up abit with minimal supporting mods? Not talking 18 or anything.. But maybe 8-10? Thanks for once again putting up with one of my stupid threads. I'm getting there i swear! :wacko::D

Standard for R32/RB20 is 10psi

Can safely handle 20+psi in standard form (not with standard turbo obviously)

General consensus around here is 14psi is considered reasonably safe for standard turbo (could last days or years, no one can say)

To be slightly more specific, stock boost is 10 psi - that's what the wastegate actuator will give when everything else is stock.

Put on a big exhaust and the boost will probably go up a pound or so. Big intercooler with less pressure drop and you gain a bit more. It's easy enough to get to 12 psi on an RB20 without "changing" the boost setting.

Basic question: do you have a boost gauge? If not get at least a cheap second hand one. Are you are aiming at 8 - 10 psi because you are making less than that now? If so you have a problem! But If you want a few more psi than 10 you could buy or make a simple mechanical boost T.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel

      What should I do next to hold the head on

      When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?

      Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.

      If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
