    Yeah I would hate to find that out too after using all my money on the turbo.. Thanks man and what do you think as a temporary fix to get the ebay ko4?
    --- Double Post Merged, Jun 20, 2018 ---
    Thanks for giving your .02 Jeff, considering you have or had an S4 and honestly ill end up rebuilding the whole car with its mileage basically so I figured I’ll aim for around 450hp for now and maybe a good bit later down the road if money allows me to then I will start going for more. I’m planning on doing methanol first or possibly extra fuel ports for better reliability.

    We don’t have E85 very close by here for some reason otherwise that would be a great option. Considering a stock block can handle around 400 what would I have to do while rebuilding mine to keep it safe around 500?
    --- Double Post Merged, Jun 20, 2018 ---
    I’m not worried about some lag either mine is just having a ton of lag which a ko4 shouldn’t have any of. My friends’ ms6 is bone stock doesn’t even have an AP on it and it spooled MUCH faster than mine in early rpms and then felt almost the same up top and mine is fully bolted with an etune from Jason. I don’t mind the lag except im not getting the extra perks of it considering it’s not because of a BT setup.....haha

    I'm not seeing in your logs where your having a bunch of lag. Just looking at a graph of one of your WOT logs you go full throttle at ~2400 RPM and you have 16 psi at ~3000. I'll be honest and say that I'm not looking much at K04 datalogs but that doesn't seem that bad. A lot would also depend on what your tune is asking your car to do.

    Even just getting a used k04 from the sale section here would help you narrow down the problem

    I've got a functional K04 w/ ~75k miles. One busted exhaust to down pipe thread. Yours for the price of shipping if you want it.

    Awesome man I will take it as long as you know it’s worth the effort to replace my other with and appreciate it! Where do you live (so ill know how long it is going to be lol) and how do we go about shipping it and paying you?
    --- Double Post Merged, Jun 20, 2018 ---
    Thanks man im going to try out @jsmith ‘s used one and see what it gets me. I mean I didn’t think much of the lag until I drove my friends to compare. It made me more worried than I already was. And something else really odd was for some reason mine felt MUCH heavier than his just rolling down the road and on regular take offs. I didn’t have anything in my car at all either so im not sure why that was either. I have 18’s that might be just a bit heavier and are offset +35 and a little bit wider tire but would that make that big of a difference? It seemed like a huge difference...
    --- Double Post Merged, Jun 20, 2018 ---
    To answer about the lag time... It isn’t too bad until I compared it to a healthy ms6. Jason @DizzyTuning done a good job with my tune and I think he surely made my map to build boost atleast as quickly as it would stock. I’m burning probably a quart every 2 weeks so something is definitely wrong and my car smokes like a diesel at wot so im assuming its the turbo. Either way im going to both build my motor and get a bigger turbo as soon as I can. I just don’t have the money for both now so it’s important to know which to actually do first.

    Worth the effort to swap in a used K04? Maybe if you are strapped for cash and not time. I would check the engine first and then move to swap K04, but that just me.

    Logistically I need to put up some pictures/signage of the K04 and then it would be Paypal to cover shipping. Will have time this weekend to process.

    Have your intake valves ever been cleaned?

    Yeah I might want to I guess. Jason said he thinks it would most likely my rings. I’ll see what I can come up with by trying a leak down test. I just haven’t done one before so first time for wverything right!?
    --- Double Post Merged, Jun 21, 2018 ---
    To my knowledge they haven’t been cleaned so that’s no good either. You think I could get a decently cheap second motor to build so I will have a car to drive until it’s ready to be put in?

    Alright so weather is not allowing me to check my car out much but I did manage to find this in my intake before it started pooring down rain.. I don’t have an OCC but could a failed PCV actually be the cause? I have heard that our cars run bad and burn a ton of oil when it goes out? Is this true because it hasn’t been replaced that i know of and could explain the bad virtual dyno results possibly right?

    That doesn't look horrible considering the mileage. Unless it was cleaned recently

    I got to dig a litlle more yesterday and the turbo inlet has the coupler still on it and the oil is all around the inlet from sucking it in. The turbo had zero shaft play and spun alright so no worries there I don’t think but that doesn’t mean the seals aren’t basically shot either.

    If the seals were shot you would know. That amount of oil is not shit seals

    Well I have everything ordered to clean my valves except the gaskets I am replacing, the actual PCV valve , and an egr delet kit (I haven’t decided where to get those things yet). I wanted the new IM gasket from AP but they say “out of stock” so hopefully they will get them back in soon so that I can continue. Lifetime guarentee on TIG ftw lol

    an EGR delete is an EGR delete is an EGR delete. AP's is the cheapest.

    Yeah I went ahead and ordered the last IM and TB gasket set he had left and an egr delete. I also bought the blaster from harbor freight along with the finer walnut material to blast with and long picks I was told I would need. I purchased a leak down tester that will be here Wednesday so I will be doing that when I get it as well. I may go ahead and try to put @jsmiths turbo on while im at it to rule out anything but the motor. If the leak down test goes as hoped for then I will continue my plan to do all of this over the 4th of July weekend as I will have 4 days to get it all finished up. Any advice for removing the ko4 (like not having to remove exhaust manifold somehow) or for the valve cleaning the first time around.

    @SharksInSpace and @JohnnyTightlips can attest that seafoam deep creep is a fukkin jizzical penetrating fluid. Spray the shit out every exhaust bolt/stud you think you'll be removing. I'd also have some extra studs and nuts on hand for the dp or turbo (they use the same studs).

    That's all the advice I have. No idea how to turbo swap a speed6

    The MS6 is just like doing the 3 for the most part, just harder because you can't do anything from under the car due to the transfer case. I used Ziggo's guide about doing a BNRS3 swap from MSF and it worked out pretty well back in the day.

    once the EGR is out of the way the K04 has room to come through the space it leaves without removing the exhaust manifold. Of course once you`re in it that far pulling the EM isn`t a big deal anyway.
