ct26 single or dual entry Options

hey guys i was just wondering if anyone had pics of the difference between a single entry ct-26 ans a dual entry ct-26.

thanks

the single entry is from a 7mgte (inline 6 3.0 from older supras)
the twin entry from 1st and 2nd gen 3sgtes (maybe others)

the single entry will spool a fraction slower than the twin entry
but flow a fraction more air in higher boost levels.

but they are still both ct26s i think the downpipe bolt pattern is different on the single entry also. and the stock wastegate boost might be different also.

Add to above,
There are 3 versions of CT26 turbos
They are all have the same CHRA (interchangable)

Single entry CT26 from 7mgte MKIII Supra, 4 stud downpipe flange, slower spool, better flow.


Twin-entry CT26 from 2nd gen 3sgte MR2 and ST185, 6 stud downpipe flange, flow less than supra one, will run out of breath at high rpm due to restricted exhaust side. Some of these (JDM) has ceramic turbine too give you better spool.


Single entry CT26 from 1st gen 3sgte ST165, 4- stud downpipe flange, flow the same as twin entry CT26,
