A VF-34 is a very nice turbo on a daily driver with an EJ20x in it. A TD05H-18G in 7cm2 housing is also nice, and has a bit more top-end.
Meh. The meth systems have gotten a lot better over recent years. A lot of my customers starting using meth and after tuning with that for a while I fitted one myself. As with anything else, good install is crucial. Buy a quality kit, install and tune properly and don't look back. Most people having problems either didn't install the kit properly, or they hacked up some DIY crap system, or they forgot to fill the tank and ran out of meth. Personally I like the Snow kits but all of the big brand kits work well.
I like to use a strategy whereby I only spray above 1bar. I use a 1bar actuator on the turbo. The extra timing and trimmed fueling in the tune is only reached in load ranges possible above 1bar. I connect the tank level warning to a relay and use that to chop the signal to the boost controller. That way when the tank is empty, you only get 1bar because the BCS is shut down and that's a safe tune on gas alone. Seriously, 99 out of 100 blow-ups are caused by the owner not filling the tank.
The fact that many revolutionary new ideas were at first ridiculed is no proof that the 'new' ideas you're being ridiculed for now are indeed visionary.
