i have being looking & seaching but cant find the answer anywere, so what i need to know is the s6 & s7 tubros the same? i know mazda did some minor changes to the s7 to get 10hp more.
i mite have to get some second hand ones sone & dont want to but s6 tubros on my car if they are not as good as mine.

 

the series 8 had revised turbochargers in 99... series 6 and 7 are the same.
series 8 revised turbine baldes and increased the boost pressure slightly to get extra horsepower.

keep your intake elbows if you are putting on series 6 turbos - as there is a good chance your restrictors are built into the nipples rather than in your wastegate/precontrol hoses.

 

thanks weetbix kid, where in new zealand r u?

 

auckland... i knew nothing about these puppies until i popped mine.
1 rebuild later and i swear i know too much!

South Auckland generally... travel to see the missus (and how many rotarys were on the motorway after the Nats yesterday but zero FD's?!)

 

im down in nelson i got me a tubro manafold and im going to put my tubros on it as mine were only rebult 6months ago

 

Those nipples are on the primary turbo compressor outlet, not on the intake elbows.
