Port and polish on m62!!
TVS is also an option. Expensive enough that it's probably better to go turbo but if you'd rather just have a bolt on upgrade to get you up that high, TVS and a good tune should do it for you
Out of curiosity do you know how much whp I could pull from a TVS with everything else? That would probably be cheaper than going turbo!!
Its very easy to achieve 300whp out of a tvs or larger.
You need roughly 20-22 psi, intake/exhaust bolt ons and about 16-17 degrees max timing. You won't be making much for torque, granted it will be more than a m62.
Toss e-85 or methanol at it and you can easily see another 40 ft lbs/40whp out of it.

Here's some food for thought.
I had 5+hrs in porting & polishing on the inlet side of this sc. And saw absolutly no change in iat's or in performance for that matter. It wasnt untill I ported the outlet we saw a gain in boost and lower iats. The secret is finding the right outlet port design. If you saw lower iat's it was because of the light porting you did to the outlet. And what you did to your sc was just the tip of the iceburg. Im sure the ported inlet did help when the outlet finally got ported.

Through my research, and what I was told by Eaton.... The outlet is specifically designed for the degree twist of the rotors. If you over port the outlet you can loose pumping efficiency. I wont argue with you though man, because unlike a lot of people on here, you know what you are doing. You must have took the magical amount of material off which still maintains efficiency, but helps bump performance a bit.
My butt dyno agrees with this magical amount of material
hptuners agreed too.. lol
I didn't believe it @ first either. Until we tried about 4 different m62 ports + log after log...

Hmmm, very interesting.

. I kinda turn a deaf ear to the engineers lol.

There's a reason only 3 exist and no pics of the outlet can be found lol
