what size fitting is on a t25 for the oil feed? some places say 7/16 inverted flare, some say 12x1.25, what is it? im trying to convert it to a 3an male.

yeah stock redtop t25.

jgstools says "7/16" inverted flare 4AN adapters for GT & T25/28 turbos (-GT)."

atpturbo says "1/4" Inverted Flare to 4AN Male to Male, 1/4" inverted flare to 4AN male to male fitting. Unrestricted version of the ATP-OIL-021. Does not have .035" restrictor. Appropriate for non-ball bearing T25/T28 turbo use. CAn also be used on GT25R, GT28R, GT28RS, GT30, and GT35R where not restrictor is needed."

and then i read 12x1.25 on here. anyway thanks for the info

I recommend you contact Harp at Taka Motorsports. He will get you the right size. It'll cost you the same as from any other e-tailer. Plus you'll get helpful tech support. It's a win-win for both of you.

it should be 12x1.25 we dont use american sizing . its simple and might sound stupid but thats my guess.

hey guys,

couple of corrections.
first at the block (SR) its 12x1.25. at the block for the CA (its 12X1.0).
For a stock T25 and stock T28 the fitting to the turbo is 7/16. If you were to measure out the true banjo bolt for the stock turbos you would find that it is 11mm. Good luck finding that anyway but the dealerships (hint there is some cross over) However the 7/16 works just fine and we actually have a shipment which arrived of 0.06 and 0.03 7/16 fittings in -3. Plus the design of the fittings are a lot better than ATP. I promise.
