Please tell us some more about your Supra. How do you like your AVC-R boost controller? Have you ever tried more than 17psi with race fuel? Is your eManage dyno-tuned? Do you ever roadrace with those Teins?

I Like may AVC-R just fine, it is easy to change your settings, and you can have 2 pre setting A-or-B, so its nice having it set 11-12 and pulling up to an evo, then just changing my boost settings to B, which is generally set from 17-18 PSI or 1.15 BAR.
I have just gotten my car running at a point that I might feel comfortable with trying more, however i have heard that the oem turbos on supras are not effeicent past 18 PSI. Weather or not that is true I do not know. I assume that the car was dyno tuned before the owner before the last, but am not sure. That is why I am planning to have it done in the next couple of months. I have not yet had the chance to do any road racing with my tein coil overs, minus my extreme speeding at times. I plan to do some of that in the future though. I have had number of decent cars in my life for my age, and I have to say that this car with this suspension has by far superceeded my expectations. Needless to say I don't plan on changing my car anytime soon! Does anyone know how to tune and tweek the HKS adjustable cam gears??

Please let me know if there was something that I was not specific enough on.

Note that 18psi is too much boost for your engine, if you're using 93 octane pump gas. Keep it 16psi or less unless running some race fuel. In general, the oem twins are fine with the occasional boost up to 20psi or even 22psi. It's your engine that can't handle that much boost on pump gas. Detonation will not only destroy the 'mighty' 2jz-gte in oem form, it will also easily blast through even the most expensive aftermarket internals... Of course, 20psi on race fuel will be proportionally harder on the oem twins than 11.5psi, but unless you've got your accelerator pedal on the floor for a half minute or more (eg. an extended high speed run), the oem twins generally handle greater-than-oem boost levels quite well. In fact, I've heard of the oem twins putting out as much as 30psi on a brief drag-strip pass (with LOTS of supporting modifications). I'm not saying they'll last forever at 20psi, but I'm also saying you probably don't need to worry about any sort of immediate turbo failure "past 18psi" on race fuel. Regarding HKS adjustable cam gears, start with them set to -3 on the exhaust side, and +1 on the intake side. If you want to fine-tune/tweak them beyond that base setting, you'll need to put your car on a dyno. Move them 1 or 2 degrees in each direction, and keep doing pulls until your Supra makes the most power. After that, do a few 1/4 mile passes and try each gear 1 degree in each direction on each pass. If your driving is sufficiently consisent, your fastest 1/4 mile time will represent the best cam gear settings for your Supra's current configuration.

If you're interested in alternatives, what about the HKS SS? It's available with a full kit, including a recirculation fitting. Although the GReddy Type-S is a decent bov, I'm sure you won't find it any better nor significantly different from the Blitz DD...
