you can use the same.
but from time to time they need to be tightened a bit..

Just have to wait a little more my friend, patience is a virtue and everything will be as it should. Keep us updated, good luck...

Steve, aka Spiky eeeeeeh, sorry Spicy3480 contacted me about the gasket, so i suppose i will have it in a few days!!
being a salesman myself, i must admit:
that's what i call after sales support!!
if you like another exhaust better than Solo, get a Solo, coz these guys don t forget about you after you buy. this pays back big time!!

Jeff and Steve, and all the guys in Solo

Arabas: glad you convinced yourself one more time that Solo is the way to go when is about exhaust

About surge, I think that happens because the new turbo pushes more air than our engine can inhale for that rpm so the air gets back to the compressor blades, stop getting into this range because you risk to blow your new compressor. I bet this happens in low rpm.

In this case sounds good, means the new turbo pushes more air with same tune than the stock turbo. I think the solution is simple, tune needs to ramp up the boost a little slower as it does now.

i mean it Kelu, someone else (and i have good examples) wouldn t reply so fast to my email. Steve replied as soon as he got out of bed!

i am not moving the car at all. as soon as i have the gasket in my hands, i will drive it carefully to get the leak fixed and then i will test the tune that Vince will have sent me.
i trust Vince on tuning. i believe it is going to be a good improvement, i could hear the turbo spooling up from 1800rpm !!

according to the very very interesting post Tomato soup posted here
http://www.kappaperformance.com/forum/index.php?topic=5557.msg76973;topicseen#new

this is the link to the how-to
http://www.astraownersclub.com/vb/showthread.php?t=214478

this is a kit they used to treat my upgraded turbo. the thrust bearing they used is what i described as thross 360 (obviously it is called thrust 360 and it is an upgraded thrust bearing).
i also saw the glue instant gasket, that Megas mentioned in one of his post.

I think it's worth saving the thread from the other forum here for historical sake since image hosting sites expire and this valuable info would be lost. I've attached a PDF of the rebuild instructions which is the single post of the other forum. Thanks to TS for originally posting. I'm going to also rename and sticky this thread for ease of searching.

TomatoSoup · « **Reply #33 on:** November 02, 2010, 03:46:15 PM »

Just a note... that how-to is written in "real" English. For the colonials reading this, "Spanner" == "Wrench"

Arabas · « **Reply #34 on:** November 08, 2010, 10:54:37 AM »

Quick update,
the gasket arrived today (actually there were 2 gaskets in the envelope ?!).
flashed it to stock and drove it real gently to the dealer.
told him the whole truth and nothing but the truth (he is a GT owner himself)
he is going to place the gasket and to make the 3rd annual service.
going to pick it up on Thursday since i will be out of town for bussines.
only thing left is a first updated tune from Vince...

fingers crossed that everything will work out fine.

GXPinKC · « **Reply #35 on:** November 08, 2010, 11:18:07 AM »

Arabas, the stars are aligned. I am sure with your expert knowledge all will be good! When Vince updates the tune, you will be good to go!

Arabas · « **Reply #36 on:** November 08, 2010, 11:25:59 AM »

Thx Ron, my GT needs all the positive energy from good people like yourself!!
i hope that Vince will have sent the tune by Wednesday and he will have resolved the compressor surge issue....and of course that my car will have gained hp

Kagem · « **Reply #37 on:** November 09, 2010, 11:08:22 AM »

I hope that too George! This is where i say i wish i will see your rear plate in a race between us, as far away as possible! Good luck....

Arabas · « **Reply #38 on:** November 09, 2010, 05:34:35 PM »

new gasket has been placed to resolve turbo to dp leakage problem, 3rd annual service completed, updated tune from Vince received.
check, check and check!
i will be able to test in a couple of days!!

do i see light at the end of the tunnel? Ron, buddy i just love the positive energy you sent me. keep sending it man!!!!!!

Kelu · « **Reply #39 on:** November 09, 2010, 05:45:45 PM »

Couple of days???? Takes you days to get the car out of garage and make some runs on the highway???
Oh boy ...

P.S. I'm glad you have everything checked but I couldn't resist not to buzz you once more

Kelu i m anxious to test, but i m out of Athens on a bussines trip and will get back home tommorow night. will pick up the car from the dealer Thursday noon and i will be testing Thursday night.
Hope everything is OK regarding the calibration of the turbo and that there won't be any surge!

Kagem · « **Reply #41 on:** November 09, 2010, 07:05:37 PM »

Was there actually any gasket? Did you assume right, that the gasket was missing? It is a matter of hours, the time has come to finally unleash your panthro, just give me a call and i'll be there! Ron, you good you! Keep sending waves of positive energy!

MEGAS · « **Reply #42 on:** November 10, 2010, 04:30:00 AM »

patience is due to pay off...don't you think..?

Critterman · « **Reply #43 on:** November 10, 2010, 06:57:46 PM »

Either pay off, or another payment due

Arabas · « **Reply #44 on:** November 12, 2010, 04:38:46 AM »

first tune reduced surge but it is still there. also while doing datalog, compared to a tuned GT with stock turbo. almost same power but it seems it has the potential, especially in 4th gear, to gain a lot.

waiting for the next updated tune and the rain to stop...

LatinVenom · « **Reply #45 on:** November 12, 2010, 12:49:18 PM »

The best of the upgraded wheel IMHO, is the part of not having to press to hard on the right foot to get the car to go.

LV i suppose this implies that torque is significantly bigger.
if this is so, in a rolling 3rd gear comparison with a stock turbo tuned kappa, there should be quite a difference.
did you first get yours tuned with stock turbo and then went with the big wheel upgarde, or was it tuned for the first time when u got a big wheel upgrade?

LatinVenom · « **Reply #47 on:** November 12, 2010, 01:33:28 PM »

It was tune for the 1st time with the wheel upgrade.
However my dealer wiped it out 8 months later with the stock tune and that sensation was still there but less pronounce.
Then DDM had an upgrade to their original tune and the torque monster was awakened even more than before.

Arabas · « **Reply #48 on:** November 13, 2010, 01:07:22 PM »

is there someone who had first tuned his kappa with stock turbo and then upgraded the compressor wheel and retuned?
if yes, did you actually see any significant increase of power?
i am saying that because it is easier when you have a tune and then upgraded wheel tune to spot differences.
Quote from Vince:
"As for power being the same, I’m not really surprised. I’ve never seen much of a difference in performance with upgraded wheel turbos. Your airflow numbers are about the same as a stock turbo."

We are still working on resolving the surge issue and then see what Vince can do about power gains.

DirtyMike · « **Reply #49 on:** November 13, 2010, 01:17:35 PM »

i ran the wester's race tune then got the upgraded wheel, then DDM adjusted my tune to remove surge.gotten some updated tunes from wester's that i logged and sent back and forth a while ago so i need to get back on the dyno soon.
