My a2 billet 6265 turbo build

[06_typeS]

Just get an empty washer bottle and measure it. I do 4 inches of meth and 4 inches of water.

[boosted_teg]

so you're measuring yours by volume versus weight.


Im using kpro as the controller. The nitrous controls

[boosted_teg]

well its been a good couple weeks of tuning. I got the meth kit installed and started to tune with it. Until i noticed some slight smoking..

took the turbo apart today

voila






Now i have to deal with seeing about a rebuild, or just a new journal bearing turbo.. either way, looks like the car will be out of commision for the summer

[Si Speed 317]

Damn, why the whole summer? I'm sure you can find a new chra somewhere for a good price

[boosted_teg]

we'll see what happens. im still driving it and tuning it. still works like it did and doesnt smoke all the time. Precision says 4-500 to replace the seal, unless the whole catridge is shot, then its 1439us. haha


I dont know if theres any wiring gurus on here, but my battery voltage in kpro fluctuates a lot.. between 13-14.4 all the time. up and down up and down.

now i checked the battery, fuse box terminals, and all 4 wires comming out of the altenator plug, they all read 14+ constant. I even tested the connector going into the ecu, and the alt wire (b10) reads 14.25. So why does kpro fluctuate so much?

[boosted_teg]

so after some work on the car, i mightve found my problem with the retarded amoutn of boost creep. previously with the 10-11psi spring int he gate, after 7200 rpm it would instantly creep to 23 (boost cut). This is with the EBC hooked up properly and being used to control the creep i had (previous year).

so i had a Tial 38mvs gate lined up, and was going to get it welded on.

well, i changed my push lock fitting on the gate and on the turbo housing. Hooked up a line direct, bypassing the EBC. To my relief, i hit 19psi by 8600 rpm.

Im happy now. Can finally get it tuned up and thrown on the dyno, more importantly get some track times.



Oh and for the Kpro voltage fluctuation, i fixed that. The oem wideband sensor was sharing its power from the relay with the power of the ecu. The swap harness had it wired up wrong. I'd disconnect the O2 relay, voila, 14-14.5 volts constant.


Also purchased a set of neogen tires. Cheap and supposibly half decent

[06_typeS]

So this means your keeping it now Adam?

[boosted_teg]

not necessarily. Its still up for sale, but ill enjoy it and keep going with it until it sells. :P

[Si Speed 317]

Lies.

[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
