Im wanting to build a nice mild set of twins, I need the truck street able so the wife can drive it while I'm gone on business but can still dust a v8 car if need be. With the help from a few guys over at CF Ive came up with two set ups.

5x .014 nozzles
60# springs
headstuds(if they are really needed let me know)
4gsk kit
ported hx35 housing
either HX55 (buddy has one for 200 brand new) or a K31

What kind of numbers can I expect to see out of either one . The 55 im hoping can do around 525 and Im aware that the K31 is more the capable of doing 525. Im looking for fact people that have used these as primary turbos and the numbers they got. Thanks much and feel free to add opinions.

 

You better add o-rings to that list.

From what ive been reading that is a debatable subject, and if I go with the 55 i wouldnt be going over 55 psi i would think and im not ramping on it 24/7 .... ok well maybe not after the first month

 

IMO ditch the hx35 pick up a he351 off a CR and run that over a s475/83/1.1t6. This will be a blast to drive on the street and will easily make the number you are looking for.

 

I would have no idea how to get a VGT to work on a 12v but ill read into it. If you anyone has some links with info that would help

 

You'll blow the gasket, if not by boost by timing.

Im not saying doing the o rings isnt necessary Ive just seen a few set ups that they didnt. they just retorqued or put studs to 135ftlbs. and timing dosent need to go much past 17 from what ive been reading.

 

Okay.
It'll blow the gasket.

been running the crap out of my truck for 10k miles 55 pounds of boost with a marine gasket and arp studs.... Head gasket is still not blown.

 

This truck had a similar setup...guess what...it lost a gasket. Lol. Just saying it might go for a while but eventually it'll blow a gasket.
