Okay im building a new manifold for the hyundai accent, we just made the head flange for it. Now I've always used this crappy manifold for the car with a t25 flange turbo and am very confused about this t3 and t4 and t3/t4 thing. I need to buy a t3 flange to use on the manifold, on ebay their all labeled t3/t4 flanges? A t4 is larger than a t3 thus a t3 flange cannot be converted to a t4 flange right? Or are they reffering to using a t3/t4 turbo which is a hybrid turbo using a t4 exhaust side (if thats what a t3/t4 turbo is?) Please explain I need to order the flange tonight.

 

I thought a t3 and t3/t4 all used T3 flange... I've never heard of a T4 flange... then again I'm a :1

 

sounds like cdm talk for t3 flange though I have seen some t3 flanges drilled for both bolt patterns.

Thats a t4 flange i guess but this is a t3/t4 flange ?

looks correct to me

 

So the t4 flange is larger but the t3/t4 flange is called that because it can support a hybrid t3 turbo?

 

PIc of turbo and ill tell you what flange you need.

 

t3/t4 uses a t3 hot side and a t4 compressor, therefore fits a t3 flange..... :1
