Brian Crower 264 2JZ-VVTi Cams: Install, Tune, Results, and DIY
Ok, I can't confirm for sure but I think I'm one of the first few people to pick up a set of these.
A shot of my GTE Setup
Start off, remove the accessory belt. Then remove the water pump and power steering pulley(optional but it give you more room to work). You should loosen the pulley bolts before you take the belt off because that way there's something holding the pulley in place so it won't spin. Then remove the spark plug cover and the upper timing belt cover. The lower one stays on.
I love the GTE motor becuase it took me a whole 10-15minutes to get to this point. No need to screw around with that annoying GE intake manifold that wraps over the top.
Get under the car, loosen those two bolts on the timing belt tensioner. It's a real pain to get in there if you don't have the right tools. Extensions, U-joint, and for reinstallation a power tool really helps to get the bolt threaded back in.

Remove the bolts on the cam pullies. On the VVTi cam, make sure you put some rags under to catch the oil or else it's going to go everywhere and leak on the timing belt. Then also remove the valve covers. Also, you should be able to slide of the timing belt.
Most of the important stuff is stripped off here.
Remove the VVTi solenoid oil line. Keep in mind, put a rag under that to catch oil as well. It shoots out a good bit. Another tip, use a screwdriver or something to pry the camshaft out. It's going to want to stay wedged in there and you're going to have to work it a little bit to remove it.
What you've all been waiting for. What do the BC cams look like? They look stock lol. Keep in mind my engine is a GTE so there's that weird looking pattern on the exhaust camshaft near the front.
Close up to know it's legit lol.
Put all the stuff back in and double check the clearances with a feeler gauge and reshim if necessary. You should know how to do this if you're attempting something like this.
If I remember right, the clearance specs are:
Intake .15-.25mm, Exhaust .25-.35mm
Once clearance is checked, put on the pullies and recheck timing to make sure it's spot on.
Button everything up and you're ready to roll.

I got it tuned and drove it around for a while. One thing that sucks, it doesn't lope lol. It sounds just like stock. According to the butt dyno, I make more power mid range and the turbo spools up a tad faster. My top end didn't have much of a difference, but that could be due to my turbo being small. The mid range definately has a very noticable difference compared to before though.

And the results after tuning are........(drumroll)...........you beat me to that last post by 2 seconds, lol....did you pick up a graph of before and after? What kind of midrange did you pick up (did you get actual before and after numbers)? What are you using to control Vvti with the bigger cams? I know you can put bigger cams in and run it on the stock Vvti control but you wouldn't be seeing max gains with that. Are you using something to alter the factory cam "timing" profile?
