I need a bigger single turbo and can't afford twins. This HTT 62/65/13ss isn't big enough with my 80hp flux injectors. I can hit 1600 egts fast with these injectors. I'm debating on either BD super B special or a 63/68/14 from ED or HTT and would like some opinions please. Thanks

i had a 63/65 and i never came close to 1600* i would have to really try to hit 1200* but i also have a manual and 60HP injectors. if you think you are hitting 1600* too fast, make sure your air filter is clean, no boost leaks and your intercooler isnt filled with debris or anything else to keep the air from flowing through it. good custom HP tuning will also help dial things in and make it run cooler and perform better.

i just saw that you have 37's and that would also make your EGT's get hotter and get there faster then my truck.

Agree with the above^^^

What do you use your truck for mostly? That has an effect on the opinion given. Also, can you describe how you are getting that temp? Are you getting there early (spool is slow) or late (charger can't keep up).

Strictly between your two choices listed, the super b special will support more HP. However, your current injectors won't fully tax that turbo. Both turbos spool close to one another, the "B" being a tad slower.

Based only on the limited info you give, I would say the 63 charger.

My truck is more used as my toy then a DD. Weekend ride and street racing. It spools good even with the big tires. My egts get hot at wot and start around mid range through top end. It's nothing to hit 1500 - 1600 egts. I've replaced my pyro, my intercooler is only 4 months old, new intercooler hoses n I've checked for boost leaks through the whole system about 3 times. While checking boost leaks I charged the system with air and used soapy water to check for leaks. My turbo puts out about 50lbs of boost at wot. I never had this problem until I installed these injectors.

HIGHGEAR

Also air filter is clean. Think there's a chance these injectors might be bigger then 80hp. I don't know what else to do or think. I even done compression test on all my cylinders and they all came back with great readings. All I know is I'm getting high egts at wot and don't know why unless it's not enough air. Need help thanks.

Is your truck very smoky when you get on it and hit these temps?

HIGHGEAR

No not at all. Very little smoke.

HIGHGEAR

If I smash the pedal from a dead stop she'll smoke until the turbo spools up then it's very little smoke. Clears up really good but not completely gone when egts are high.

I would go super B special then... although it's more turbo than you probably need. Thing is the 63 only puts out a couple more lbs/min than the turbo you currently have. So, if you get the 63, you may see the temps drop from 1600* to 1500* (maybe 1400* if really lucky) while beginning to spool about 100-150 rpms later in the band. The B will begin to spool about the same point but be just a tad slower overall in total spool. It will support much more HP though.

Frankly, I'd go with a ball bearing turbo though...

HIGHGEAR

which ball bearing turbo would you recommend

CRF450R RIDER

I remember reading that ball bearing turbos need or should be liquid cooled. I don't remember all what it said, but it's worth researching.

HIGHGEAR

I'll check into it. If not a ball bearing turbo maybe just get a super B special. I'm been reading a lot of good things about them. I appreciate the feed back from both of you guys, thanks.

It depends on exactly which model. The plumbing is very simple. (Literally 2 "T's") But the advantage is greater cooling of the bearing units and no need for "turbo cool down" as the water won't coke the way oil will.

The water cooling is reliable in every way. One just has additional plumbing to do.

The Garrett GTW3884R with 64mm inducer. It will spool faster than your current turbo, equal air to the super B special and a lot less back pressure than the 63/68.

Oh yeah, and it is oil cooled too (not water cooled).

However, it will also be the most expensive choice.

In the end, you have to make up your own mind.

I noticed you have also posed this question on other forums...

All I will say is do some good research and educate yourself. Be very wary of specific turbo fanboy comments. There are a lot of lemmings out there and much in the way of intellectual inertia that is not conducive to solving your issue.
