depends what gear youre in

high gear and a hill will produce a high load at low rpm, hence, boost

try it on the freeway....sit on 5th and hit the pedal a bit...boost will rise quick but it wont feel like youre on boost

then stick it in 3rd and give it the same load. the car will feel more responsive but will be on less boost.

less torque, low rpm....ie climbing a hill, need boost to get up hill

hope that makes sense

This question has been posted over and over particularly to Skyline newbies. Your stock boost gauge is NOT in psi unit. If you look closely they were marked at 100mHg unit. +7 (the max) is 7x100=700mmHg unit or approximately 14psi.

So if you're accelerating hard and it goes up to what you think is +4 psi, it's NOT 4psi but 400mmHG or approximately 7 or 8psi, which is normal stock boost.

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      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
