Just wondering, is there anything I need to know when I remove my t25 turbine? I hope it's not too hard, I blew the seals on my turbo and am gonna get it rebuilt. Any special tools I need? Or anything to look out for?

Thanks all

remove o2 sensor and move the oil dipstick tube to the left by removing the 10mm bolt and drop the down pipe,
replace hardlines with Circuit Sport lines

When you take off the mani you will need to move the part of the radiator hose that connects to the engine. And definitely get those turbo lines that Sileighty_85 mentioned. You dont want to get stuck with gay ass oem copper lines.

In general you only need 10mm, 12mm, 14mm and 17mm sockets or wrenches. Liquid Wrench helps

Disconnect the downpipe from the turbo exhaust elbow.
Unplug your o2 sensor
Disconnect your oil feed/return as well as your water feed and return lines.
Remove all 8 exhaust manifold nuts
Disconnect the hotpipe and move it aside.
Pull the manifold out (I found it easy if you remove the hardlines coming out of the brake master cylinder, it gives you more clearance).

Remove, swap turbo.
Install in reverse order.

That works but I Reeaallyyy dont think ya need to make that much more work to remove the BMC Hardlines, I just pulled one yesterday as long as you move the D/P and that Oil dip stick tube everything is cake.
But whichever ya wanna do

i left my dip stick tube on and had no problem. the only thing i realy took off was the o2 housing. and came right out.

If you are a complete fool and decide to keep the stock hardlines, replace the copper gaskets for the hardlines at the very least. You WILL leak out all of your coolant.. Buy more.
