So I've been driving the new setup for a while and it is night and day. I don't know if it was the manifold, the exhaust or the turbo but holy crap did I have a lot of backpressure with the HX30 and stock US manifold. That set up was ok off idle, came up to boost fast at 2100 and hit a wall at 3000. Now my off boost torque is awesome, boost builds slowly and alda starts to enrich around 2800 but once that happens this thing moves! My only complaint is that in slow traffic 3rd gear is a little weak between 2100 and 2600 but not enough to need to downshift in most cases.

I did a bad 0-60 run and it seems to be around 8 sec, maybe high 7's. Need an actual stopwatch. So, I am probably making around 240 or so hp. I need to check that I have no fuel restrictions.

Next up is new tank screen, 3/8 fuel line and maybe a stronger lift pump spring. I also need to tweak the trans to shift about 300 rpm later, it is shifting at 4800 and I have good power up to at least 5200. For whatever reason, I'm really hell bent on making 260hp with this thing before I get a new pump...I'm actually pretty happy with how it is now but what fun is that?
