What size oil and water fittings thread into a Garrett T25?
What size and grade head to exhaust mani studs do I need?
Should I drill out the mani and turbo flange to fit 10mm studs, or will 8 be enough?
More coming, I'm sure...

The coolant line fittings are 7/16 x 20 (-4) to 14.0 x 1.5mm.
Oil Line fitting is a -4 to 7/16 x 24 Inverted Flare.
I believe the exhaust head studs are 10 mm x 1.25.
Go with 10 mm studs! 8 is not enough if you run any track/autocross events. Even then..... If anyone has our manifold w/ 8 mm studs, will we drill them out to 10mm free of charge.

Sam, you'll probably also need to drill out the turbo flange too. If you don't have a drill press, I think it would be a lot more economical to just pay a machine shop than to ship it all.
The 8mm studs I have here really look undersized to me.

Kinda suck at these measurements.

Ben, don't listen to anything you get in this thread. That turbo has got some really insane fittings. Did I leave anything in that CHRA as far as fittings go?
The drain "flange" is a metric thread. The oil feed is NOT 7/16-24 inverted, but if there's a fitting in the feed already it's the converter I bought to convert it to 7/16-24. The water lines are kind of normal, but you're still going to have to size them at a pneumatic supply store.

Steph, this turbo is a Garrett TB2522 Part # 465749-5001. I couldn't find any info on Garrett's site about this turbo, and I found no way of contacting Garrett directly.

Go to a Fastenal store and use their bolts to find the right threads for the fittings, and then either source the appropriate fittings somewhere online or have them machined if you get in a jam.

There were two fittings, IIRC one of the water lines and the oil feed. I have no idea what sizes either of them are. The water fitting was too long and bumped the exhaust manifold, so I took it off. The oil drain flange looks like it would thread into my mitsu's oil drain, but does not. And it doesn't have the "ears" to bolt the fitting to.

Sorry if this was mentioned already but the holes on the garrett T2 flange are 9mm ID. If you use a 10mm stud you also have to drill holes in the turbo larger.
kinda obvious info but I figured I'd share. I used 10mm studs on paul's new manifold.
I'm using 5/16 studs (close to 8mm) on my new TT manifold cause i have studs and nuts lying around. It's easier to get a smaller wrench on the 5/16" studs.

Sorry to bump this but im starting to search for the lines that I need and I need to know one thing. Are the above hose measurements internal diameter or external diameter?
I have piece of the cars hose sitting on my desk and its 1/2" external and 3/8" internal. Which is it?
