wich turbo should I buy?

[gear jammer 91"]

I know I just asked a loaded question, but I need help deciding. Two turbo's are out of the question, my pocket
book can't support that kinda power. My truck should be in the neighborhood of 300hp, and right now with my baby H1C and a 16cm turbine housing I'm hittin 32psi+/- and 1400 degrees (1500+ without the w/m) I need to get my egt's down and I would like to get my boost up closer to 40psi. Right now I can spool my turbo pretty easily, but when I have to detune for mileage it gets kinda laggy. I've been looking at either a PDR hx-40, a S300, or a HX 35/40 hybrid with a 14cm turbine housing. My concerns are,

1. turbo lag, I would like to at least keep it the same if not reduce it.

2. egt's, I don't want a turbo with too small of a turbine housing, (12cm)

3. upgrade ability, I don't want to be shooting my self in the foot by buying the wrong turbo for bigger stick's, or whatever else I think I need down the road.

I asked for it, so let me have it. Help me decide witch turbo is right for me. Thanks in advance.

Well Item #3 rules out the hybred turbo's. Remember they are a 3" exhaust outlet. If your thinking about pushing some power somewhere along the line your going to run into the 3" barrier for air flow.

The stick shift trucks seem to like smaller exhaust housing. The S300's are listed with 12 or 13cm housing. This would keep your lag down and not hurt in the drive pressure department.

The HX40 would spool just a little slower than your maxed out H1C, but it wouldn't spool that much slower.

Here is a link with a little reading in it on HX40's. Pay attention to MMillers posts. His truck is a stick shift. I have ridden in it before.

I read that one yesterday. I like MMillers results, and the hx-40's do have the best price. I just wanna be sure cause I don't have a lot of cash too play with.

Ive said it before and I will say it again. My basic S300G is a nice little turbo. Its a 57mm and 14 hot side. Its gated at like 32 and unplugged it goes to 35 with my current settings.

Richie the S300' are good from what I have seen many people post about them.

What I don't like is the venders going sky high on prices for them while the feeding frenzy is on. When I was trying to decide on a turbo a while back. Most of the venders didn't even want to talk about holset's. All they wanted to push was the S300's for $500 more. The price has went up sence them on the S300's. For some reason the HX40's haven't went up much at all. I wonder why? The most likely reason is there are many places selling holset's. So finding a good price is easyer. How many places are selling S300's. Only a hand full of places list them moded for Dodges.

PDR has a decent pricce on the s300's. My concern with buying an s300 would be that the turbine housing would end up being too restrictive for towing with the fuel turned up, and too restrictive if, I upgraded injectors. I really would like faster spool up, but I'm not willing to sacrifice egt's to get it. PDR claims their HX-40's spool like they have a smaller turbine housing's. If anybody has had any experience with their turbo's it would be great to hear what they have to say.

YA.. mine is the stock unit not the pricey one. I got it from a local cummins dealer. That is the turbo the shop is using for an upgrade unit replacing hx35's on second gen trucks. I would have liked the 62 or 64 compressor unit but they were out of my price range. I am not sure of the map range or the hp range but it is nice at my current settings.

Anyone selling S300's won't give you a map chart I asked.

The PDR HX40 is the Super HX40 other venders list.

A HX40/16 will spool almost like your H1C with a 16cm. I see very little difference between my HX40/16 and the HX35/16 I removed on spoolup.

With the fuel mods your listing you can spool a HX40.

Thanks for all the info guys. I think I'm gonna go with the pdr hx-40 and use the money I save to buy the required 4" down pipe. I think that would be my best bet for the power I want while still keeping the egt's safe.

I bought the PDR 40' got it on last night, so far so good. It whistles good and loud, and my egt's went from around 1400 with the baby H1C-16 and W/M. Now The highest I've seen is around 1200, and thats with the W/M off. Now all I need is an adjustable boost elbow, the waste gate is opening at 25psi, and I want it more like 40.
