Greddy Turbo owners thread
Post your observations and improvements here .
To start off I can report that my Greddy has lasted 40,000kms on its last rebuild and still going strong . It has survived 3 track days and 3 dyno sessions producing in excess of 300whp from about the 10,000km mark. However most of the miles have been as my daily driver .
This is how I've run it :
*Oil restrictor used
*5w40 synthetic oil used from day one
*Oil changes at roughly every 3-5000 miles depending on if tracked or not
*Never really wound it down more than a few seconds on shutdown - except at the track.
*Always warm up the engine before going WOT but probably have gone WOT on numerous occasions before the oil is fully warmed up .
*Combination of short and long trips
What other observations/improvements can you report ?

ALL GREDDY TURBO OWNERS , and other FI owners as well
Take a look at this thread and check your vacuum pipeing . It would seem that a LOT of installers are getting this wrong .

Leave it open Brettus... I'm a few thousand miles into a bone stock greddy setup. 10w-40 royal purple changed every 2000 miles. Still am babying it... hopefully that'll change soon.
daily driver for me... I put about 45 miles a day on it... 20 or so each way. always try to let the water get to at least 140F before driving and I stay out of boost / rev territory until I see my oil creep into the 160F range.

Guess I'll play since the admission to this thread is cheap.... so far I have put just over 400kms on my bone stock Greddy turbo. I have the Wastegate actuator signal tee'd into the Jet Air Hose as close to the charge pipe as I could get it. So far I have only hit 1-2psi of boost with my AFR's dipping into the 10's as soon as I creep over 0psi. I am waiting for my first mazdamaniac calibration to come back to me hopefully this upcoming week. We just got our first dump of snow this week but I'm sure it will melt before winter really settles in here and I park the car. I am using 5w30 full synthetic Royal Purple and am thinking about starting to mix 4oz of premix oil into my fuel tank on every fill up (probably won't start doing that till next spring. Oil will be changed every 4000kms; as it has been it's entire life N/A up till now..... will keep everyone posted as to how my WOT run goes when I recieve my new MM map.

Here is a log from ealier today running at 10psi to about 6500 reducing to around 8.5 . Somewhere around 300-310whp
MAF curve is nice and smooth , very little dip at aux port opening but a noticeable spike in afr at that point .
AFRs a little lean high up
anybody else able to post a logged run like the above ?

Here are my observations!
This is the second time this kit has been installed, blew the first motor due to improper tuning on my part. Pretty much a bone stock GReddy install, minus fix #2, a BOV and...thats about it lol.
When I got the car back with a new engine in it, I reinstalled the turbo kit with a proper tune this time. The turbo lasted for maybe 12 hours and seized on me, the turbine had frozen up and the wheel eventually sheared off the shaft, making a big smokey-oiley mess.
Rebuilt the turbo with a 20G-TD06H CHRA, 360 deg. thrust bearing, etc. It was actually new. The 20G is only about 2.5mm larger then the 18G as far as inducer size goes, so I wasn't looking for a huge improvement.
So far i've got 5k miles on the turbo/engine and look forward to many more! Just got a boost controller and am getting a proper intake, I couldn't fit the Mazdaspeed intake with the new intercooler and the vertex front end like I had planned. Replaced everything in the kit minus the manifold, downpipe and intercooler piping.
300g/s at 5-7psi

I did the work myself on the compressor housing to fit the larger compressor, otherwise the turbine fit fine as it's the same as the stock T618Z turbine. 
Housings went on without a problem and the alignment marks on the CHRA were the same as the GReddy turbo. (The detent on the compress side, and the alignment pin on the turbine side)
Now I just need a larger actuator..I'll see how this boost controller does, but I can't seem to get more then 5-7psi with the actuator tightened as far as it can be.
I got the CHRA off of Ebay from Kinugawa (sp?) turbo, I was pretty weary at first, but at 475 bucks it's not exactly a cheap price, either. I have to say the quality is pretty exceptional, out of the box it had absolutely no shaft play and i've yet to have a problem with it. I could've gotten it in a water-cooled format but decided it probably wasn't necessary for the power i'd be running. I see full spool of (5psi at least) under 3k RPM's.
The 60-1 with a TD06H was another option, oil and water cooled for around the same price - But I wasn't willing to mill that much out of the compressor housing myself.
My AFR under full-load for the entire band is about 11.9, deviating by about 0.3 points -22 degree timing nearing redline and about 13-14 degrees under peak torque.

Brett I haven't looked under my car in a while but when you adjust the wastegate arm are you removing the downpipe or are you able to reach up there and get the e-clip off without removing anything?

this thread almost makes it look like no one has a greddy kit, i wonder how many posts i'd get if i started a Knightsport Supercharger Kit Thread.
Mind you just tried contacting Knightsports for a replacement air filter, since mine is 2nd hand kit and the filter is abit damaged on one side.
according to KnightSport, "We do not sell the kit, nor parts for the kit, unless the car is in the workshop" guess that means a long time until someone else gets the kit ey.
Oh btw Brettus, there is a few guys on the com.au Monkeiboy that has contacted you, was wondering if you could give him a hand with protuner and his greddy kit.

True to a point . Those are mostly build threads or greddy fix threads . This is supposed to be more of a free for all , similar to the Pettit thread
Well I think it still counts as the Greddy kit if it started out life as the base kit and the turbo still has the word 'Greddy' written on it . Does that make sense ?

thats what happens when there are only 4 or 5 of them out there belonging to people who get on the forums, and those 4 or 5 are either incompetent or never satisfied to leave good enough alone
