Engine/Transmission (1998.5 - 2002) Turbo Fit

[Harlacher]

I want to put a bigger turbo on my 1999 24valve. I have a beefed up transmission, 4 inch exhaust, RV injectors, high output injection pump, FASS and Edge Comp. Everything has been built up slowly with plans to get a better turbo someday. I decided that today was the day and called BD about their super B turbo and I find out that because I have a BD exhaust brake that connects to the turbo I can’t use their turbo.



If I get rid of the exhaust brake and go with an “in-line” brake, however it will cost me anonther $1,000. 00.



Does anyone know of a way around this or of an aftermarket turbo that will fit and give me the boost I need?



I am fit to be tied. Any help would be greatly appreciated. I don't understand why BD (who up to this point I have been 100% satisfied with) would design something like this.

Doesn't make sense you have a "BD" Exhaust Brake, and "BD" can't accommodate, or doesn't make a turbo that you can use and maintain "their" EB. I can't wait to see what other folks here think about this one. I'd be super bummed out as well.

I don't see where BD has done anything wrong. The sold you a turbo mount brake for a hx/hy35 turbo. It's not their fault you decided to upgrade to a bigger turbo and it doesn't fit anymore, bigger turbo's need bigger housings. They have the in-line one which is marketed just for this situation, you just didn't buy it. It would be like being upset with Peter at SB clutch if he sold you a clutch for stock truck, after you told him it would remain stock, then slips like crazy because you added 200 hp. Sell the old one, buy an inline one so this doesn't happen again.

That's what I think, don't be offended.

Get the hybrid Turbo from Ind. Inj. They have a 35/40 Using a your stock size elbow. The drive section is a 12cm and the compressor is a 40. Has stock feel spool-up with a higher PSI on the top end. . This might be your best choice.

The first question should be what hp do you want to end up at

500 Horse power

500 HP is my goal. I am at 360 and 1,000 ft-lb of torque with a stock turbo so I don't think I am way out of line here. With 360 HP I am seeing high EGT.



I have thought this out and agree somewhat with what you said Sam. However, before I bought the exhaust brake I bought all the transmission upgrades to hold more power. When I bought the exhaust brake I did not mention I was going to someday want a bigger turbo, and that is my bad. I did not mention it when I bought my 4 inch exhaust either; in both cases I didn't realize it was necessary.



Again, the transmission upgrades came before the brake. Do you think Peter would have mentioned anything about upgrades if I had spent over $2,500. 00 with him buying a heavy duty clutch? Lets say I had 3:56 gears and wanted to go to 4:11 and they wouldn't work. Again my fault if I did not tell him but would he have said anything?



I am not coming down hard on BD for this. This is my fault; I was just surprised that BD, a company that sells Diesel Performance parts, would sell a part that would limit what they could sell you in the future. An adapter to make things fit does not seem unreasonable to me.



BD said the same thing that you said Sam, sell the brake I have now and they would give me a good deal on an in-line one. Although, that is the way I might have to go, it is my understanding that the in-line brake does not provide the stopping power the one I have now does. It works real well and I would like to keep it.



BD is a very good company and the first I went to when I decided it was time to buy a new turbo.



As an afterthought I have almost 200,000 miles on the original turbo and it still gives me 30 lbs of boost. Do most of them last that long? (I know 30 is a lot but that boost is coming from to much fuel; lots of black smoke and high temps. )



I will check out the turbo you suggest also, Eric and thanks.



Thanks for the input and thanks Gary I will call them this afternoon.

OK, so you want keep your lunch and eat it to! If you have an exhaust brake you must tow. The HX35 is most likely the best towing single available. The slippery slop is getting really slippery under your feet. You will soon be spending more and more to get it back to a towing truck. Maybe you need two trucks or twins!



I went from a HY35 to PDR35-12W so that I could keep my Banks 4" turbo mounted exhaust brake. You might talk to them about a PDR35-14W with your setup, but you may not have large enough injectors for the 14 housing. They will rebuild you current HX35 into a PDR35 if you can be without it for a couple weeks.



Is the BD brake 3. 5 or 4"? If it is 3. 5 then it is a restriction anyway. SNOKING

Lunch

Don't understand why I would make a lunch if I didn't want to eat it.



I have read numerous articles where people are using these trucks to run the quarter mile in under 12 seconds, change tires and pull their trailers for a weekend of camping. I don't know if I will ever run the quarter but it would be very cool to have a truck that blows away corvettes.



I bought my Dodge with 175 horsepower and while going up any grade with my trailer, I was passed by everything on the road. It was a piece of junk that I wondered why I had paid $30,000. 00 for. Knew I needed to fix it or burn it As soon as I started upgrading I blew two stock torque convertors. $2,500. 00 later the torque convertor and transmission problem were fixed. I bought a few more add-ons and now I want more and you are saying I need two trucks?



I am very confused about the rest of these post where people are doing exactly what I am trying to do and loving it.



I have the RV injectors and beefed up injection pump supplied with a FASS. I get plenty of fuel and as I was doing my upgrades the plan for more air with the fuel has always been there. The BD exhaust brake is a 3. 5 inch.





So I do want to eat my lunch and yes I want to use that beefed up transmission and other money I have spent on my truck to produce a better, faster, stronger truck! I will be pulling and that is why I didn't want to go with a super b or anything else that was competition only (they are getting in the 10 second range). In the area of 500horse, (settle for 450) a 12 second quarter (settle for low 13s) and retain the ability to tow. YUP I guess I do want my lunch and eat it too. I have paid a lot of money to keep that ability. Down the same line I do not want to throw money away either.



What are we doing if we are not spending these big bucks to get our trucks to perform better? I don't think I am trying to do the impossible.

Paul, I have one of those trucks you're talking about and I think what SNOKING is saying is that to get to a 500hp DD/towing toy is an expensive journey that just doesnt pan out for most. I personally from experience would sell the turbo/brake you have now. Get an S300 type 62/65/12 turbo and an inline 4" brake to go with it. Also 30psi isnt that much, 35psi from an HX35 is the top end of its range but the motor can take 45psi before studs/rings. Also realize all mods lead to other mods to keep up. At 500hp towing will send temps soaring, coolant/trans/EGTs will ALL need to be addressed.

AND THEN, you read posts that the best towing turbo I ever had "was the original HX35"! Very very slippery slope! SNOKING

They will rebuild you current HX35 into a PDR35 if you can be without it for a couple weeks.



If I go this route do I loose my towing capability?



Thanks for all the advise and I will look closer at what I am trying to do. I am not towing now but I will in the future and want to keep the truck where it will tow a 10,000 pound trailer. It did great at that before. Transmission temps were high at times, EGTs would get high if I put my foot into it.



I just figured more air to keep the EGTs down.



What about water/methanol injection? and

A lot of what they do for a PDR35 is to make it spool faster. Give them a call or email. They do machining on the compressor housing and use a different pin wheel. Exhaust housing it your choice of stock 12, 14 etc. With small Jammer 1 injectors and comp not tapped they said I should run a 12.



With a comp, you can go to main level one and not add fuel, just timing and that should help with towing EGT. 1x3 should be good for towing. There are other injectors that may give lower towing EGT's, like Mach 1. 6's.

Who are they? Sorry I must have missed it some place.

When/if you decide to go to larger injectors they also have a twin kit based on the aforementioned turbo.

I called and they said the best way to go is with the PDR HX 35. I am thinking real hard about doing it. When you did it did you see any horse power gain? Can you tell me what it did for you in performance?

 

[SnoKing]

Remember I went from a HY35 to PDR35. Fuel makes power, air cools! I did it to cool while towing. Someone else should pipe in. Up the string someone talked about another hybrid.

[SnoKing]

You will not see as big of a difference, as you already have the larger HX35. But for around 5 bills it is an upgrade that is not that bad. SNOKING

 

[SHobbs]

The 3rd gen e brake will accomodate a 4in. outlet then you can use just about any turbo. I believe a member has done it. Yeah I know, more money but it's just a thought.

 

[THoltz]

Hi Paul,



I still have stock injectors and the stock HY35 turbo. I to, am contemplating a different turbo. I don't want to sacrifice too much spool up but I need more boost and I want to team it up with an exhaust brake all at the same time. Keep us posted on what turbo you decide to go with and how it performs. Take care.



And a Merry Christmas to all!!!!!!!!!!!!!!
