An aquantance who has experience running both of these pistons has advised me that ROSS would be the better route for a DD, high HP street car ;). ROSS are heavier, true, but IIRC, they are lighter than a stock piston as well ;).
I have a set and haven't used them, they're still in the box, still debating on getting Ross pistons instead. If you're needing a set let me know and we may work out something.
Damn, I missed that as well until I just read your post.
Take a look at your A/F ratios, that is the main reason why many do not suggest using the LEX AFM in tandem with stock 440's.
DDP's: Divorced Down Pipes. The purpose of these is to let everyone know when you've hit your target boost. The wastegate opens, thus slowing down the exhaust turbine and compressor side to where it is only spinning so fast to reach the pre-set boost of your choice. The bypassed exhaust gases...
Nah, he's not running out of fuel, although cleaned and blueprinted injectors would be a nice peace of mind to have. You don't want to unscrew the AFM screw with the A/F's already that lean, it would only make it worse. Increasing your fuel pressure should help to bring down the A/F's a little...
If your wanting to bore the motor for added power, you may want to reconsider.
Read my thread on how much the 7M can breath. You most likely will not feel a power increase from a bored block (you may feel it however, if you were low on compression before teardown). The real gain would be in...
Uh Oh Jay, you may want to edit that post then. That's not your true HP because it wasn't a 1:1 ratio pull. ;)
You'd hate to get knocked out of the GTE powered club now, wouldn't you? :sarcasm:
Hey bitch, no hating on the Metros, wait until I've got mine back up and running, I'll show your sand blaster motor who's boss :wuteva:
No probs, just letting you know I've never raced the supra, but I've got a couple of other cars as well that have seen a fight or two ;).
