This is on a 1st gen truck but i thought you might you guy's might know more about this.

What's the spec's on the PDR Super S300 turbocharger. I'm lookin to buy a new turbo and don't know what to get, the super s300 or the 62mm s300. Those custom injectors in my sig are somewhere around 370's to 400's, i can push enough fuel to spin my h1c to 39 psi with the 18 cm housing and I can put the pyro on 1600 degrees if i'm going 80 mph or more with my foot all the way to the floor. I don't do much towing but when i do it's pretty heavy ( trailer and the load= 17,000lb) so i need something that can handle towing but i don't want to wait 3 hours for it to spool up.
I'm still in the middle of replacing my head gasket but i figured now is just as good of a time as any to replace the turbo too but my wallet is going to bleed.
