Kinugawa 25g turbo thread for Evo X
Well, I've had a long streak of badluck with my EFR blowing. I bought a new kit with the 25g. It hasn't been working properly becuase of either an exhaust leak, boost leak, wastegate problem. All to which i have attended to many times and still can't seem to figure out. I'll say though with barely boosting 18 psi and boosting super slow it feels like a monster. I can't imagine when dialed in 24 psi DD and a monster e85 tune 29 psi.
Just heard back from one of the guys running this turbo
so far he VD 500/380 on E85
looks promising.

Yea pretty much, can't even tell what's going on down there. I'll find ou this week. Looks like this turbo can flow a lot so I'm excited.
I have a question to ask about this turbo install.If everything on the car is primarily stock can this turbo be installed with the stock downpipe o2 housing and stock intake ?? Any feedback you can give me would be much appreciated as I'm ready to pull the trigger on getting one but I don't want get into a situation where I'm buying one part after another.
also the inlet will need a new coupler, other than it will fit the stock setup fine.
Do you know if they make an adapter to retain the stock intake? Also your saying that there will be no problem fitting the stock pipe?
update.
I am going to finish this tomorrow.
But the kit is not a true plug and play.
As of right now I had to remove the acd heatshield ( which I am going to wrap ).
The stock oil drain needs to be modified to fit the stock location.. they should've also given a steel braided line for this.
2nd you can't use the stock inlet, so I had to buy a J silicone pipe.
As soon as I am finished tomorrow I'll post some pictures.
And give some VD results on Pump
thanks!

Well finally finished.
This kit like I said its not a plug and play. It does take a lot of elbow greese to work.
Such as
Coolant drain hoses need to be extended
Oil return line had to be cut and a high temperature hose was used instead ( I am going to switch it to a steel braided line)
I had to use heat wrap to cover the J-pipe ( does not use the stock inlet)
there are other things I did but to be short it was not a straight install.
My Tuner and installer will post a dedicate thread on the results as well as put up a dyno figure
I can tell you this VD showed 474/340 @ 27lbs of boost ( hp reached peak at 7550!)
spool was not until 4100 .
the issue we came across is that the stock spring on this turbo is not capable of keeping wastegate shut during spool. we will probably need 25 psi spring..
anyhow take the vd results with a cup of tea.. next weekend its going on the dyno with e-85
pictures to come. I am to tired for it lol

Some of the pics:
Here are some of the lines modified ( also couple heat wrapped!)
close up to the Hot Pipe and Silicone coupler
Stock Heatshield works
The little monster ( oil return like needed to be modded to work!)
Closer shot to the oil lines
So lots of little issues to get this turbo to work. Today i had to turn my car into a shop ... somehow the bolts backed out of the manifold and the turbo. ( I noticed boost was dropping way down)
Note to those doing this.. Make sure you use the studs and not re-use the stock bolts (STUPID me)

Although material wise it was only $75.00 more to get it to work.
1) You need a new Intake 45 degree coupler.. 4.25 to a 3" to work with the AMS intake
2) You need a J pipe to fit the turbo ( 2 to 2.5 ) 110 degree
3) You need high temperature coolant hose to extend the coolant drain and coolant feed
4) You need to take the stock oil return line. Cut in 2 ..
Cut close to the engine .. extended with a high temp hose , then use a 90 degree AN fitting.. extended again with more high temp hose and make it fit with the new provided Oil drain line from the turbo.
so not that much but it took way to many trips to the local supply store.
Yeah I wasn't to happy on the amount of work needed to make it

Coupler won't hold the heat.. I ended up getting a friend of mine to do a nicer outlet for the turbo
I guess this turbo has a wierd harmonic and its backing out the bolts to the turbo.
So I am not looking at welding.
Would I do this over again?
No I will never try this out if I am the first one to actually document all of this.
When it does work, this turbo is awesome.
So here is my take , do the above. But defintely make a J pipe out of either steel or aluminum so it can hook up to your stock UICP.
Use studs vs , longer stock bolts and crush washers..
Get a grimspeed turbo gasket.
Also get the 1.5 bar spring for the wastegate. If you plan on running more than 27lbs I highly suggest it
anyhow thats my small update.
Going to dyno on a mustang dyno hopefully in a couple of days.
