Guys, so I tried to install the long laying china turbo knee and not only that one hole is so close to the knees body I am not able to turn it, also the angles of the flanges from knee and downpipe are not exact same. I didnt want to try it with force cause I thought, it will only f**k up the gasket. Would I have to lose the whole exhaust pipings straight to the end to get some "room" into the flanges angle or what would you guys recommend?
Heres a picture with the closer side tightened by hand and looking at the remaining gap.

Well, yeah. Try loosening everything.

Just because something is sold as "bolt on" does not mean that it will mate up with all the other OEM or "bolt on" parts that are there. Especially Chinabay exhaust bits.

I would suggest, if you cannot get it all to go together while everything else is loose without leaving a gap somewhere, that you are going to have to pay someone to cut the flange off one end of something and weld it back so that it will mate up.

Yeah exactly, it is common for parts to be a few degrees off flat. If a couple of them go the same way you end up with that sort of issue. Not many china parts are as bolt on as they claim....

Cut and reweld at a zorst shop.

BTW thanks for the introduction to new terminology "long laying knee" and "downpipe" :) I take it that is the first piece off the turbo (dump pipe) and piece from the dump pipe to that cat converter which we would normally call front pipe?

And get them to weld a flex section into the midpipe rather than dildoing about trying but fking up getting the 'ultimate' angle. Knob 2 birds with 1 dinger having a bit of movement for fitting, and engine movement.

      The alloy coolant reservoir has a sight glass, so as long as I can see coolant in the sight glass it's GTG, as for PS, it isn't anything catastrophic if it gets low, and as it hasn't lost a drop since I have owned the car I cannot see it being an issue, even after putting the "big block" 2.5 in....LOL The only time it gets slightly messy is at oil changes, as the oil filter sits above the frame, and I need to use a plastic bottle with its bottom cut off to catch the flow when loosening the filter

      Good on you for taking on the job, but it is a big one. Even if you have bolt on manifold and turbo, you will need: Post throttle pressure source to boost controller to wastegate (and FPR, and ECU/MAP sensor) Pre throttle pressure source to top of BOV(s) Oil feed - you can take that from the standard port in the middle of the block Oil return to block under the turbo - this is much trickier than it seems to route a decent/wide pipe past the manifold. You really can't use rubber hose because it is way too hot there, and also the oil out of the turbo core is a bit frothy so it needs to have a decent diameter Water feed - you can take that from the standard port in the rear of the block. Water return - mine runs to a T into the heater box return, just make sure you don't create a high point making bleeding hard. All of those lines should use 200 series style teflon braided hose with heat shielding because everything needs to be routed past the manifold. Also a turbo beanie is a really good idea to minimise the chance of the car catching fire (under bonnet lining in particular) You also need to decide a cam cover breathing solution as well, will you vent externally via a catch can (probably illegal) or return to the intake (plumbing required and can oil up everything over time) Keep in mind the intake and exhaust piping in the engine bay will be custom so you either need to be able to fab ally and steel or have someone you can get a car that isn't running to. Get the wideband fitting welded into the dump pipe at the same time. Also, just my opinion, a screamer pipe attracts attention and doesn't add power, I'd plumb it back if you want to be allowed to keep the car on the road. BTW do you know anything about how healthy the motor is, and what power you are targeting? Doubling or tripling the factory power on an unknown motor is a little risky. Also fuel system will need some attention (pumps, high current hanger, direct power and earth feed, injectors etc)

      To back this up, I'm always looking on the outside, seeing the level, and then opening it up anyway, as I'm worried the level I've looked at, is more so a scunge line. Then you end up dipping your damn finger in it too depending on the type of tank you're looking at just to make sure I'm not going insane.   PS, Mark, polish up the none moroso one a bit and then give it a clear coat. The Moroso one looks to be way shiner (not mirror polished, just shinier) and it'll still look weird with the two different alloys beside each other. Either that, or Id probably paint them a flat black...
