i found the opposite while using the stock ECU, NO BOV caused no end of issues (RB25) with stalling and throttle response.

GTR BOV went on, problem went away :laugh:

But stalling etc is largely due to driving style as your already aware im sure :woot:

Not sure if its the complete opposite.

Throttle response was up with no bov (i.e partially on the throttle through a corner then nailing it) however it did have stalling issues and often backfiring on down changes or coming to a stop. The bastard always would stall driving in to my driveway.

Nothing I did to the pfc prevented it stalling or having the jerkyness drivability issue at low rpm when making some boost.

No bov... It did feel nice when I selected the next gear on 'full boost' partial throttle with a slow gear change as I didn't have to wait for the turbo to spool, boost was just there instantly. But.... I don't drive like that 90% of the time. Probably why I get 10.5-11l/100km's.

lol at chirping... I can chirp fourth if I try.. :ninja: lol not that its too good for the box. Chirping has everything to do with the clutch and how one shifts or should I say slaps.

I know this is a very old thread but does anyone know where you can get a plumback hose for the GT-R stock BOV? It's like 40mm from the BOV to 30mm on the black hose that goes back to the intake. I can't read the vernier caliper that well so the size maybe way off but you get the idea.

Thanks.

Hrm... i think i have some in the boot of my car.

Lot of effort/cost to send to where you are - surely you can just get some hose made up mate?

And by that i just mean any old hose cut to suit, you dont need it to be any specific type really

I see. Doesn't have to be any special reducer hose. I was searching for HKS straight reducers but can't find any online. I'll go to the workshop today and see if i can get a normal hose to fit.

Thanks R31Nismoid.

      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

      By MBS206 · Posted

      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)?

      Chris' Toyota Mark ii JZX110

      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.
