Good DD/Towing Turbo

Hey guys, I am looking to get a good daily driver/recreation towing turbo for my truck. As you can see in my sig, the PO put a "Super B Special" on this truck, which is no good for a DD. bad lag/response below 1600 rpms and high EGTs.

I was looking at possibly a Holset HE351CW or Airwerks S300. Any suggestions?

My main concerns: little fabrication work if needed, reasonable price range.

I don't have any experiance with turbo's and asked around and found the super B to be a good choice for me, it's better than stock and if I feel the need to go bigger I'll use this on as a top turbo for some compounds. I've also heared that a 62/65/12 seems to be good for daily driving.

Those injectors you have OEM Bosch. Are you saying they are the stockers??

A Super b is a good charger to DD & tow with, but it needs fuel to spool. If you don't want to put injectors in, you may want to try a set of .024 DV's.
You also may need to spend some time on your AFC to give it more pre boost fuel.
What plate you running?

The turbo you have is a great one, but you don't seem to be lighting it. It can be laggy, though, and your fueling isn't helping the situation. You already have an s300, and a 351 is much smaller. It would probably be best for you to go smaller with your fuel setup. The 351 or a smaller s300 (62/65/14) would be your best bet.

Thanks for the info guys, but I am definitely getting rid of the BD Super B Special(64/71/14). It is a competition turbo, not recommended by the manufacturer for DD and towing. It pulls super strong at 1600 rpms and above. I can easiliy hit 60 psi in no time. I have modded the IP, tried many settings, put there is only so much you can do with a competitiuon turbo designed for high rpm operations. Spools slowly on the bottom end and EGTS build fast at lower rpms under a load.

Not for me, I want a turbo, possibly 62/68/0.83 specs, I have heard this a good all-around combo for DD.

62/65/12 tows nicely and spools close to stock and will support 400 cool hp or nearly 500 on the edge of melt down. With what's in my sig I can easily hit 50 psi of boost and it pulls hard to 4000rpms.

If you are hitting 60psi of boost I doubt your injectors are stock. I doubt stock injectors would light a super B special any where close to 1600! If some one was going to dump 1500 on a turbo I am sure they would have spent the 350- 650 for a set of injectors to go with it.

After market injectors are made with stock housings, no way to tell by just looking at them.

That is a good point, you are probably right. The Super B Special is really strong in the upper RPMs, just not suitable for the street.

my bad. I missed the key word "special" in your first post.
At any rate, you should find out what size injectors you have first thing. Pull one & measure it or bring it to a knowledgable shop that can ID it for you. This will give you a base line in which you can go by when you install the new charger, unless, you just buy a new set of sticks sized to your new charger. If you decide on selling yours, your gonna need to know the size anyway
As far as turbos, I agree with 86burbguy on his sizing. A 62/65/12 is a great DD charger that will have good towing manners coupled with a set of 5X012 injectors.

I am not sure how much I want for my Super B Special, will let you know when I get the new one on. I have heard that the Holset HE351CW turbo is a good choice for daily driver/towing on a 12v. Anyone install this turbo on their 12v? What mods did you have to do to get it to install?

Seen alot of guys running 60/68 BW box unit with .91 housing. I was running 63/68 BW with .91 and spools awesome and got a adapter plate from PDW to make it work on my 3 piece manifold because flanges are T4 and run cool and breath better. Those box units with HX40 flanges machined i paid 875 shipped to me and paid 50 for adapter.
