To my understanding it was probably just the whole combo with the Gt3071 compressor wheel, trim, .63 turbine and rb25 manifold that caused the issues with boost control that "bhdave" and "33" was experiencing despite fighting with ebc,dump pipes and actuators.

"The Mafia" used the Gt3076 .63 with minor problems which i think could have been sorted with a stronger actuator, so clearly even being the same size wheel and ar turbine, it will react totally different depending on what compressor it is bolted to.

I think the Gt3076 .82 will be a little too lazy for me and capable of power i am not aiming for.

cams might have helped response a little in my case but the lower compression would have taken away just as much. The 3076 .82 did feel a little lazy at times in in hindsight i would have gone for the 3071 .82, I would not have gone a 3076 .63 as i really dislike the feeling of a large compressor coupled with a small exhaust housing

      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
