I have recently come across a t3\t4 turbo and i plan on putting together a kit to run it on a stock b18a1 running 6-8 psi. Going to be used for street driving.
My question is if the standard turbine wheel will be too restrictive because I have not been able to find any other stage wheels to buy that will fit this housing. The housing is #20358-72 0.63 a/r standard housing and it does not have many options for different turbine wheels.
Also the original turbine wheel is not the right one and may have been from a different turbo because the inducer is about 2.25" and the exducer is 1.75" and looking online the standard turbine wheel should be 1.802" 2.324" (via garret part number 409646-0051 T.I part No. 2-A-0296)
Note: The turbine max seems to be inducer about 2.375" (2 3/8")
exducer about 2.063" (2 1/16")
Would this 'standard' turbine wheel \ housing combination work with a TO4B compressor on my application or would it be too restrictive? If pictures are needed I can take some.
