What turbo to upgrade to?
 

Ive been looking around and talked to some people, but im still looking for answers. I heard an s300 turbo for my truck would be a good set up but then i heard that its not much of an upgrade from my little stock hx35. I got 150hp injectors with a raptor 100 lift pump and stock vp. Sometimes my truck cuts out but i think its because of the small turbo and over fueling of it. I was looking somewhere in between a 65mm super b or a 66? what do you guys think!

Super B is not a 65mm. I'd look at a 64/71/14.

no way just do a s475. my buddy got same stuff as you on his 01 6 speed minus the quadzilla and it runs mint on his truck

Thats a little bit big for a single Turbo. You would need 200+ injectors to spool a 75mm Turbo and it wouldn't be very streetable.

Luke

so an 62/65/14 would be to small?

Do you tow any?

Luke

i think the 62 is about perfect. its a good all around turbo. wont make HUGE hp numbers but will do everything pretty well if you plan on using your truck as a truck. an S475 is BIG

and Luke how laggy is the 71 compared to a 65????

Its not to bad depending on mods.

Luke

you can't beat the 62 on a vp truck. I used mine as a single 62/71/14 made 488 with ddp 110's, then added a 475 to the bottom and some ddp 200's for 575 ddp 240's 603 and lightning III for 683. The 62 as a single was great and could tow anything. take out the big injectors with the compounds and run the 200's and it towed like a dream

How is fuel economy with these mods? I realize you all may have different combinations& gear ratios & tire size etc ,so just wondering if there was any gains here besides power?
