My a2 billet 6265 turbo build

[boosted_teg]

well good new and bad news.

Good news first: Boost creep was minimized. I replaced all my pushlocks with a higher grade, same with the line and voila. was hitting 16 psi and it was falling to 12.8 by 7000rpm (boost controller dropped the boost). So i was pretty excited.



Bad news: Took one last drive tonight to see if it hold up in 4th. Held 15lbs to 8600rpm... then cruised along, pulled off the highway to go home and it was running on 3 cylinders. Air fuel in boost was holding 11.9-12.1 ( aem wideband) so either the injector quit working or the sensor is bad. There's Lots and lots of smoke pouring out of my catchcan and dipstick. Vitals on Kpro showed perfect. 190 degree temperature, -21.5 vacuum at idle, 13.9afr at idle. So what gives? Number 2 spark plug is missing the electrode, so it got pretty hot. My guess, metled a hole in the piston or valve.

Oh well. Ill take the head off next week sometime and post some pictures. :P

Wow, I don't know what to say. I hope this isn't as bad as it seems to be. what's your plan of attack if that's the case?
