planning on building a custom kit , and could use some help with what to use . thanx

 

if you want 1 psi get a small turbo, if you want 45 psi get a big turbo. the t3 .42/.48 is good for a quicker spool, but the t3 .60/.63 has more power potential. It really depends on what you want to do with it, how much power you want to make and where in the power band.

 

a t3 .60/.48 is great for daily drivers.

 

Depends on what you are looking for in a daily driver. My car is a daily driver and I run an HX35 (similar to sc61 in flow). It doesn't spool till around 5k in low gears and 4k in upper gears at 6 psi. This is awesome for me on my b16. I can stay out of boost easily when driving around town, traction is not that much more of a problem in first gear as it is for many turbo cars I know. The car pulls hard up top and I stay in boost when shifting. I have no need for a smaller turbo. A turbo as massive as an hx35 may not be for you but it works for me.

Summary: do your research and find out what you want out of the turbo and what fits your desires, then come back with more detailed questions.

 

Just go with the 48/60

 

Got myself a T3 .60/.48 and have yet to install it but decided to go with this one because it was better for daily driving and spools up a bit quicker than the .60/.63 but doesnt give you as much of a PUNCH in the high end...

But in the end, I'll be happy with it--as soon as its on my car. :P
