i'm either going with a T25 or TDo4 13g.
i can get either for very cheap. which one is better?

 

They're pretty comperable, but I'm using a t25 and it's beautiful.

 

^^ i agree. i love the t-25 on my d series. full boost at 3 grand.

 

They both suck. Buy them, sell them 4 more, then get something bigger!

 

^^ well....

Lemme know what your setup is man. What turbo you should use totally depends on your setup. People think that if you stick the biggest honk'n turbo on your car, you're gunna get the best results... that's not true at all.

If you post your goals/setup, we here can let you know what size turbo you'll need. The 13g came off of automatic 1g DSMs... very tiny, I'd still go with the t25.

 

I'd go with the t25 since they are comparable and the t25 is alot newer.
