i know the hx35 is stock what are the others that will bolt right on and be good. what are the different sizes?

 

hx40 will bolt on, which one are you looking for/goals?

 

if your running the stock manifold a turbo with a t3 foot will bolt right up.

what are your power goals for your truck?

 

Down Pipe will be different for all aftermarket turbos and HX-40 style as well.

 

wats the diff between t3 and t4?

 

the size of the turbo foot( the peice that bolts on to the exhaust manifold). Wish I had a pic, but sadly I do not. The t3 is smaller than the t4 foot.

The t3's are on your stockers,hx40's, and s300's ( some can have a t4)

 

As said above what are your power goals for the truck and an after market manifold is a good idea as most flow better and some stockers have a tendency to crack.

 

I have a super hx 40 runs very nice but had to get the fab on when it came to the exhaust.

good luck with your next turbo. I went from hx35 to what was said above and noticed a little difference
