I've got a question for you turbo guru's. Check my sig for current setup. I believe I have enough fuel for a mild set of twins as is. Currently I still have the factory turbo but I just so happen to have a brand new HX35W with 14cm exhaust housing. The HX35 alone is not much better than I have I imagine and not worth much to sell so I figured I would like to build a set of twins. Plumbing is no problem as I have a TIG welder and reasonable skills. So the questions: Will the HX35W be a good start? What turbo do you reccomend for the big side? Also, any info you have on home built sets would be very helpful. As always, thank you for your assistance!

 

it will be fine, hx35s and a ht3b will push a lot of horse power and drive much better than some of the bigger turbos on the street.

 

What vendors should I look at for an HT3B?

 

try this

www.turboparts.info

If its a dead link, type it in on yahoo and look it up, look in their inventory sheet..

use these keywords in the forum search:
twins with hx35 and BHTB, HT3b etc lots of long treads about 6 months ago

 

www.powerbypoole.com for the HT3B. He's got two in stock right now.

 

You can also look at the s400 for the primary. Rip Rook is selling all kinds of cool stuff for twins now...adapters from holset to switzer, etc. When I can afford it, I'd like to go the BHT3B route since it's a tried and true setup that's cost effective and vary driveable at 500 HP (prolly 400 for my first gen)

 

What is the differnece between the BHT3B and the HT3B? Does anybody have some turbo assembly numbers off of their own that they could share? I have a Cummins guy that will get me one for a real nice price if I can figure out an assembly number.

 

the b is for the flange connection on the discharge of the compressor[iirc] or it could be for reverse rotation, but i think that is the e in the part # to tell you the truth it doesn't matter, i have used both of them. the 90 degree adapter for the flanged ones is expensive if you have to get it from cummins.

 

I thought the B meant it had the MWE in the compessor housing?

 

If you make you own you might consider looking ahead and making your setup so you can use multiple turbos. I run a Dodgezilla/K31 for a daily driver. Really fast spool, good up to about 475-500. If I want to keep decent spool and have a bit better top end, I change just the hotpipe and run an SPS62 on top. If I want to play with higher hp and lag isn't an issue I swap to a B2.

 

I am getting ready to do the same thing, and i was thinkin i would run a HX35/40 over a s400. You can pick up a s400 from city diesel for $650 which i haven't found a better deal on a primary yet.

 

From what I have learned going to a set of twins they are great to drive. I think going with a small set makes them alot more friendly to drive. Watch what big turbo you buy and don't get a oddball flange like I got ahold of. The guy sold me some kind of cat flanged turbo. Will the s400 spool as fast or faster than the 3b turbos? I'm running the small 22cm housing and spoolup is immediate! Try them, you'll like them!

 

It all depends on what size housing you have on the s400. I agree with RonA about switching out turbos. The only thing I'd say differant is rather then change out the bottom turbo I'd change the housing. Right know I have 40/16wg-3b/26 set up. So for towing I might go to a 35/14wg or 40/14wg on the top and go to a 22/23 on the bottom. I'm going to be going to a dodgezilla/s400 set up and what I'll do then is for daily driving and towing I'll have a 1.10 A/R housing on the s400 and then for pulls I'll got to a 1.32 A/R housing. The smaller housing on the bottom helps spool up big. On MY set up with a 26 housing the primary starts make boost at 7psi. With a 35/14wg-3b23 the primary makes boost almost as soon as the secondary. It's all most like the light together. Total boost isn't much, and it wont make any top end power, but it tows great.

 

The 40 I had didn't light until 1700, the twin setup I have on will light the bottom turbo easily by 1700. For the money I don't think you can beat the hx35 on top of one of the turbos everyone has mentioned. If you were to buy the hot pipe from rips already tacked together the cold pipe is a cinch to make. I probably had the cold pipe made in a hour.
