Engine/Transmission (1998.5 - 2002) Newbie turbo advice wanted

[Luke Warmwater]

Trying to match components for Denver area (5000k'). I currently have mods in my sig with stock hx35. I don't tow and am looking for more a street racer setup vs a towing setup. I can run the comp on 3x5 now and maybe touch 1400-1600 degrees once a day and then just for a few seconds as by that time you are moving along. Max boost with elbow is around 31. Truck spools quick with 4:10s which makes its nice and snappy up to about 2500 rpm where it goes flat quick. I am willing to give up a little on the bottom for better pull out on top. Would like to be able to set the box to kill and be able to stand on it for 15 seconds up a nice pull and keep it under 1400 on 3x5 and 1600 on kill or at least slow down the rate of increase a significant amount. Also, would like to at least consider what turbo would work best being that it might end up being utilized in a twin setup somewhere down the road. I'm sure this topic has been thrashed before so pardon the newbiedom of my question. Thanks



Pros & Cons?



14cm housing on stocker?



35/40 Hybrid like DZ?



PDR 40hx?



ATS Aurora?



HTB2?



KSB1?



KSB1-2?

How deep is your wallet?



A hybrid with a 14cm or a 16 cm turbine is a good start, but since you already have the 4" exhaust, you could go with a 40, or any of the higher end turbos. Then you can start thinking CLUTCH.

Yeah, I know my clutch is on borrowed time but I am surprised after reading many comments on here, how much and how long it has held. My stock clutch has taken mach2s with comp on 3x5 for quite awhile. It will slip on 4 or 5 so I just make sure and not cross that line.



Wallet depth is not my issue until we get into twins territory. That puts too much hurt on right now. What I would like to gather is what works up here at altitude with a 450-475hp target. ATS is the only company up here that I know has first hand knowledge so I'm just wanting to hear from people who are running different turbos at altitude that may be able to shed light on what works with what trade-offs. Thank

Luke,i went with a Modified HX35 with a wastegated 14 housing.

I like it well enough, Still can hit some high EGT's quickly on a hot day when its on higher settings. There are a few opinions on this link.

I would go with at PDR HX40-16. Good spool up and excellent top end.

Also, you can use this turbo when you want to build twins.



I've been running mine for over 2 years without any issues.

What elevation? Thanks

How does a dodgezilla hibrid or ksb1-b-ex3 compare to a pdr40? temps, spoolup etc? Thanks

A cam would ultimately help you the most up there. It will help EGT/smoke/spoolup and has no side effects. A bigger turbo will take from the spool, which means more smoke too, to help the EGT.

 

[Luke Warmwater]

Keith, I'm curious as to what I might be able expected at 5500' from a different cam in regards to EGTs? Also, is a cam change in the Cummins equivilent to what it is with a gasser v8 in regards to time and effort? Thx

 

[KLockliear]

Typical drop is about 200* or so. You could do as much with a turbo, but you'll sacrifice spoolup to get it on top. Pick a middle-of-the-road turbo and do a cam and you'll be happy.



I guess the swap depends on your mechanical abilities and shop/tool selection. We can swap them here from running to running in about 4 hours.
