just a small write up on the turbo project.
its sorrt of like a blog of the whole build... its a long read, and i'll keep updating it as time goes.

today on the hwy i did some vag com temp testing.
i wanted to see how good the OEM system is to see how important would the purchase of an oil cooler would be.
also, i wanted to have a baseline of the oem system on the NA car.
the test was simple: on a 93F day
-20 mins of miami traffic (stop and go) [heat soak]
-20 mins of 2.4k RPMs (6th gear) [baseline on normal operation]
-mins of 3.8k rpms (4th gear) [temp test]
-mins of 5.0k RPM (3rd gear) [high temp test]
-10 mins of 5.0K RPM (1st gear) [low speed high temps]
RESULTS
================
OIL:
Despite my attemps to overheat the oil, and to test the capabilities of the heat sink, results were impressive: The oil temp was fairly constant. Regardless of iddle in traffic, or any condition i threw, temp was always: 100-110C
Coolant:
looks like the oem radiator is easy to heat soak. On miami traffic the temp rose up to 96C, which was the highest (10 mins not moving).
While moving, at any RPM the coolant maintained its cool at 90-92 C.
The only danger i see so far is the coolant. with the right conditions, the oem system can be "beaten".
Fuel:
Despite my efforts, and a wide range of RPMs, and some wot runs showed no timing pull on any cylinder.
this is great.
AFR too was always on point.
This means that the fuel looks good, the O2 sensors arent faulty, spark plugs and coil packs are working as they should, knock sensors are doing their jobs and injectors arent dirty.
Ambient temp:
Weather for today was sunny (as always in miami) at at 32C with humidity at 60%
Conclusion:
Everything is perfect. Oil analysis shows perfect results as well. All ready for the turbo.

this week will be like christmas... according to my email:
"all orders have been shipped".
this includes the entire "turbo kit" from JDL auto designs.
the intercooler and injectors from CTS tuning
and the boost gauge and pod from MJM autohaus.
i'll post pics as things arrive..

updating with tracking info:
-Injectors: ETA Friday
-intercooler: ETA Friday [same box]
-BIG order: thursday the 5th
the fact that the intercooler will arrive on friday, kinda pushes everything back a little bit, sorta.
On thursday:
-change wastegate spring
-remove EJ headers
-measure the oil fittings and connect to turbo
-remove oil and oil pan
-bolt on the exhaust manifold
-bolt on the turbo
-Turbo intake
-Turbo downpipe
-mock the wastegate pipes
-mock the charge pipes
Friday:
-ship ECU
-install intercooler
-do pipes from Throttle body to IC
-do pipes from IC to turbo
[what ever i didnt do on thursday]
Saturday
-weld all the pipes
-remove intake manifold
-polish intake manifold and timing cover
-connect the injectors
-wire tuck
Sunday
start putting everything back together
Next week:
connect the gauges
=========
until everything is PERFECT, i will drive with no hood (easier to do all the pipes and stuff) no front bumper and no underside cover.
it should help with temps a bit too.
============
i expect to be completely done by friday the 14th.

From here on, its all about turbos and the turbo build.
The BIG box
Silver Tial BOV
V-band flanges, v band clamps, reducers, t-bolt clamps for silicone (2", 2.5" and 3"), and oil lines
Some pipes and silicone
more pipes
Turbo with oil lines connected. Oil feed and oil drain ready to be fed!
