Talk to both the company that rebuilt my T78 and the company that origionally sold me the turbo. Both are very reputable: Rotary Performance and Majestic Turbo.

Kevin at Majestic told me to go with a .110 restrictor and Rotary Performance said to go with a .06.

Running a -4 an feed line and a -12 retrun line. The Turbo has been rebuilt with a larger 72.5mm compressor wheel if that makes any differance and is going on a 20B with a racing beat oil pressure regulator.


Have ordered two .06 restrictors from ATP (thats the only size they had) with the idea that if the .06 is too small I can always drill out the size of the other one.

Any suggestions?

Thanks

 

i couldn't tell you what greedy wants, but most journal bearing turbos will be happy with somewhere around .080 and .100 restrictors. bb's like less oil.

 

Tanks for the input, will probably drill out one of the restrictors to .09 and see how things go,

 

Is this for a Mitsubishi T78??
