Like the title says i just bought this turbo and i want to know what the stock internal wastegate is set to? If anyone knows it would be a lot of help. The serial number on it is 14411-50F00 and they came off of red top sr20det"s. Thanks

 

hook up a air line with a regulator and a gauge. Start at 1psi and work way up.

 

that would be pretty easy accept i dont have a regulator or a gauge yet. does anyone know anything about these turbos?

 

hey buddy that wastegate should be set stock to 7psi my buddy has one on his red top i called and asked him. he got his engine stock from jspecauto online and it came at 7psi. hope that helps ma man.!

 

Awesome ya that helps a whole bunch. Thanks a lot! Do you know if it is a T-25 flange? im pretty sure it is but i want to double check before i go and buy a manifold that does not fit. I've searched all over and no one seems to know exactly what kind of turbo it is. From what i've found its either a T-3 or T-25. Any suggestions?

 

measure it and compare it to dimensions below. first pic is a t2 flange and second pic is a t3 flange

 

perfect thanks for the pics and dimensions!

 

yes its a t2 flange, stock boost is 7-8 psi. i ran mine at 12psi for about 2 years with no problems. i just pulled it off for a holset tho!

 

Those stock actuators tend to hold up pretty well also. I ran one on a Miata at 15psi for several years with both MBC and EBC... totally max'd out at that point and running a big intercooler, but can be done. Unless you've got no choice, I'd stick with the 12-13psi range for efficiency.

 

ya im running stock internals on my D16Y8 so i doubt i will get much past 8psi if need be. Thanks for the input
