I was fitting my new turbo today and ran across a couple of problems that I thought i’d share and hopefully will help out others from making the same mistakes as me.
Anyways if you’re planning on fitting a larger turbo on your motor, there are a couple of things that you should do - to save having to do more work in the long run.
As you can see in the above image, my compressor housing is touching the engine mount and this is stopping from being able to tighten up the exhaust manifold bolts.
I’m going to end up shaving a bit of material from my engine mounts :tickedoff:
If you have a new turbo that you will be fitting on your engine soon then please read on.F
Bolt your turbo to your exhaust manifold, take off any oil and / or water lines for now. Now put your new turbo setup on your engine to see if you will have any clearance issues. It’s impossible to know if you will have any clearance problems until you’ve actually fit the turbo. This may seem like common sense, but if you’re anything like me and seriously eager to just get that turbo on your car then this should help.
Tighten a bolt either end of your exhaust manifold (if you can of course). Feel around the compressor and exhaust turbine housing to see if there will be any obstructions.
In my case, the compressor housing is sitting on the exhaust manifold and now after spending a couple of hours connecting oil and water lines, i’m going to have to take the turbo back out and grind back the engine mount to overcome my clearance issues.
Of course you could opt for top mount / high mount turbo setup. This would get rid of any clearance issues but in my case, I didn’t want to chuck my custom dumppipe and re route all the oil and water lines.
