And are you serious about the billet WGA? That's a bummer, it looked nice. I still have the stock WGA from my 8 turbo, should I use that? How much difference do you think the FP would make over the billet or 8 stock WGA?
Reporting back on my Kinugawa self install. It's been on the car for 2 months now. It was tuned and made a disappointing 318WHP with boost coming on late and slow around 4800RPM. I needed to take the hot side off the turbo today and in doing so, I noticed a nasty looking exhaust leak in the V-Band that holds the exhaust housing to the turbine carriage..
It's bad enough that it scorched the outside of the band and left soot marks inside. I could also smell a strong exhaust smell under boost despite having no other leaks I could find.
I contacted Kinugawa by email today, any ideas what could be the problem?

That is not an exhaust leak my friend, that is burned assembly lube from manufacturing, mine had the same, that's why you can see the stain looks like a puddle on both sides, an exhaust leak will look more black and powdery looking, i disassembled mine before i even put it in the first time and did notice a lot of assembly lube
Try preloading the wg actuator , that did the trick for me, and no, the evo 8 actuator don't work, i already tried.

I have the GM 3-port boost control solenoid though so I don't know if that's as important as the preload. George said it should be about 'half a hole' of preload and I know it's nowhere near that now.
Good info, how about preloading the evo 8/9 actuator via actuator mod? https://www.evolutionm.net/forums/ev...pring-mod.html
That's a good idea to try, Kinugawa sent me a 25 psi one which solved my problem, let us know if you try it.
Turbo came in today and i bolted her all together. My intake also came in. Just waiting on my intake manifold to get here and she'll be ready to get tuned. I did a dry fit of the turbo/manifold/o2 dump and it appears there is a fitment issue somewhere.
I can already see that the stock oil drain line is not going to fit. I may have to end up cutting the line in half and connecting it with some high pressure/high temp hose.
Also, from the looks of it when it was on there and i'm not for sure it I am certain but it appears that the square side of the compressor cover was hitting the block. It may just be because of the drain line and o2 dump weren't seating right.
Has anybody had any kind of fitment issues like that?
Here's a few pics the goodies.
some of the port work. they didn't go very deep
but at least it's gasket matched and smoothed a bit.
My side kick
The intake i pieced together for about $50. SD ftw
All together.
Ported exhaust manifold
P&P 10.5 25g
O2 dump

Looks bad *** bro, this is gonna be fun!

kunugawa td06 25g with billet wheel, 11.5cm hotside, antisurge and billet actuator.
kinugawa sent set of spring 1.5bar, 1.7bar and 2.0 bar
boost controlled by ecu with grimspeed 3port solenoid
i'v put 2.0 bar and on boost off(0% wgdc) i had only 1.1bar of boost
on 100% wgdc i had 1.8 bar
BUT! look at log
No matter what wgdc i set in range 0 to 4k rpm, boost hit only 0.8 bar(12psi).
maybe someone faced with such a problem?
