So I keep hearing people say that the chrome thickness on a turbo housing is thicker then that of a non turbo housing... but I have compared them to the best of my ability and can't see any differences... is this something that only an electron microscope will see
where does this information come from. Is it myth or fact?... and if it is fact, can someone please provide me with the facts thanks |
nope that part, the expensive hard part, is the same.

not sure what ur sayin there j9fd3s,but does that mean they are the same?(except maybe porting style from n/a to turbo)

Thicker chrome would require that more iron be removed in the grinding operation. Also the heat transfer rate would go down as the chrome gets thicker. Just my opinion. I could be wrong. Lynn E.

interesting,would love to know if they are different for sure.

Between housings of a given series, the only difference between n/a and turbo is the diffuser in the exhaust ports on n/a housings. |
And machining for water ports or not...
And knock sensors... Minor stuff! |

And knock sensors... Minor stuff! Have you verified that the S4 turbo housings had the casting for the knock sensor above the spark plugs? I may be wrong, but I thought the S4 knock sensor was in the center iron near the oil filler tube. Ive always heard that the S4's had the casting, but all of the cars I can remember had the sensor in the iron. |
what about port timing? is the n/a port timing and port same as the turbo ones?

Knock sensors? What are those https://www.nopistons.com/forums/pub...DIR#>/wink.gif
