What set up do I get (what turbos do I use) I am uneducated when it comes to choosing turbo sizes.

heykw

Do they sell a kit with the turbos and the pipe work, should I use a hx40 or get a hx35? what will the total cost be do you have this kit on your truck?

Smaller on the top, bigger on the bottom

I'm not an expert, but Rip should be able to hook you up with an S400 or HT3B that will work with your stock turbo, and all the piping to connect everything.

Most guys run an s400 underneath either an s300 variant= HTT, II, or any other run of the mill s-300 or stock HX 35, or HX-40.

You need to determine your final HP goals first, then size the turbos. If all you want to run is the fueling mods you have right now, you would be time and money ahead to just buy an HTT 62/71/14 or 13ss. and a down pipe for 1600 bucks.

If you need lots of towing capacity or frequent lower stress towing, then you should spring for the twins.

FYI you can get a standard S400 turbo from Dallas Turbo for 650 bucks. I think Citydiesel has them for about the same price as well.

Member Rodram has a hotpipe= connects top turbo exhaust outlet to bigger bottom turbo exhaust inlet for cheap, look him up and send him a PM, lots cheaper than buying a new hotpipe from RIP. If you use his pipe, your gonna need to pickup an HX 35 somewhere. You can find them in great shape for 300 bucks. Then you might as well buy the rest of the parts from RIP at sourceautomotive.biz since it will take serious downtime to fab up all of the pipes on your own. I think you could do it all for 2500 bucks including buy both turbos. Or you could spend a little more and get an Airflo cheaper super B knock off S300-57mm compressor and bigger wastegate/hotside for 850 bucks to use as your top turbo. If you did that, you would have a bigger set of twins that the BD towing twins and have air for 600 HP. If you go with a stock HX 35, you'll have enough air for 550 HP.

Or you can just run the 62/71/14 like I mentioned earlier and make 521 HP with higher egts but still very useable power!

I don't have them. What happens to my truck will depend on how the next 6 months or so... Kind of at a crossroads

Txdiesel007 has a set with a S400 and his stock HX35, and talking to him about them has really impressed me with them. More maintinance, but you give up less. And Rip can hook you up with all the pieces, or a complete kit, or something inbetween.

Like BB said, the 62 would be plenty for your current fuel, but if you can spend the money, I say go big

With the fuel I have know what could my truck run in the 1/4 time wise and what would be the HP
