I was watching the 13b engine build video today and he recommended using 13b 86-91 turbo rotor housings and intermedate housing with 89-91 na rotors.

I found that the part numbers were different between the series 4 and series 5.



Since my 90 spit a apex out the front housing exhaust port, i will possible need a new rotor housing at the least, so why not make the mods now.

Which turbo housings will work for my 13b na?

they all bolt together the same. The assembly process doesn't change.
