hey guys im about to put a TO4B A/R .6 rear A/R 1.15 on my stock series 4 13bt,has all the other bits like stand alone etc.Now just wondering about everyones experience with one? such as reliable? street driven ? or weekend warrior?



thanks guys https://www.nopistons.com/forums/pub...IR#>/bigok.gif

to4 b is too small not much performance gain. if you are going with a t4 platform at the very minimum get a to4s you will be much happyer with that turbo. since you already have a standalone and all that ****.

really? TO4S? well im not aiming for performance...this is just a cheap upgrade as im pickin up this turbo for 300 and its been rebuild just have to replace a gasket on the bit where the oil cooling is.I know this is laggy turbo just want to know how reliable is it on a stock 13bt with say a good tuner etc tuned for 12psi?As this car is my daily driver and im sick of the smaller turbo

to4b is about stock size , wont really do much for you, id save up and spend the money on a to4s. responce will be better, performance gains will be great and the reliabluity will be as good or better then the b.

Which compressor wheel do you have in it?
