You could try something like the new HKS 7460R, which as you know is a B.B. turbo and thus is a relatively fast spooler with longevity thrown in. Then pair it with the new GSC S1 cams which feature a high lift, short duration grind. This is gonna spool real quick even on a 2.0L engine. The 7460 has pretty decent topend as well. You could then throw on a set of adjustable cam sprockets for good measure so as to be able to advance the S1 cams to maximize turbo spoolup.

I still don't feel like I lost anything down low with the S2s. If you look at my chart on the previous page the torque is fully loaded by 3400 rpm and holds about as nicely as I can ask for til redline considering it's just a stock IX turbo. I still have a few bottlenecks in my car too... stock DV, stock O2 housing, stock intake and exhaust manifolds as well as a catalytic converter.
They idle pretty smooth as well. There is a little lope but nothing too obnoxious. Plus its a nice feeling getting pushed into your seat all the way throughout the powerband instead of just during that initial torque spike.

IMO do it right the first time, especially if you're paying for the install like I did.

[QUOTE=taylorgang;9531232]so revolver cams would probably be best for low end? ....QUOTE]
You do realize that Revolver cams are out of production don't you? Thus, it would be next to impossible to find a new set as vendors no longer have any in stock . You would probably have to settle for a high mileage used set.
Considering that even when new, Revolver cams had a fairly spotty quality control record, buying a used set may be a hit or miss proposition at best.

Use almost any cams you want-- advance the intake to cam to 108* and exh to 110. If you want run split duration 272 /264.--with more intake duration and you will build a lot of midrange an low end. The HKS turbo is awesome for this-- I ran 272/264 HKS on stock turbo and it was real nice--now running 274/278 with the HKS turbo and its slick...running same cams straight up---lost a lot of lowend..advanced the intake got it all back. In general low duration high lift is the ticket--more intake duration and advancing the cams will build more low end as well--the combo works.

To increase the rev range you need upgraded springs and retainers, correct? Just curious about this... I couldn't really find any exact info. Let's say you want to be able to rev to 8K RPM without blowing up the motor...
