To make full use of the super 75 you need to run 24+ psi of boost otherwise you should be able to make the same amount of torque with the super 61 under that boost level. I can make 18psi of boost with my 60-1 hifi at 3000-3500rpm depending on what gear I am in, it also keeps making power all the way to red line.
thanks

How much power would that be ? what is a wet turbo ?

A super 75 will make more hp because the torque does not really drop off but the peak torque will be the same between the two.

if the power curve is that much better with the t 75 then the car would be that much faster

So that headgasket failure is caused by... detonation... detonation = heat...
So the #4 cyl is a hot spot, #4 cyl fix would be.... to get all the air bubbles out with the LR kit? Kinda makes sense... maybe along with a colder thermostat to keep engine temperatures lower? Makes sense, to a point.
I've found some oily gunk in my coolant system and have an APE2 kit on my car... 16 pounds of heavenly pressure from yee gods... well anyways, it's got some other issues too... ie broken stud in head... crap. makes for a leaky exhaust, right? yeah... half tempted to replace the lifters at the same time... woe is me.
anyways, sounds like the deal is heat. Detonation in JUST the #4 cyl? There's method to the madness.

By running the engine at 11.5 this has the same effect of lower the combustion temperature , the key is to get the operating temps down as 93 is very susceptible to knock with the higher temperatures ...
As you discovered going to a harder gasket will not solve the problem. I have never seen the need for better than stock gaskets if combustion is properly controlled, i would prefer to O-ring the block
