I agree with Catoiler, that is why we bought them. Friend had his first hook ever, so side tracked(given direct orders not to break anything by the boss, took them 2 hours to pull 20 gassers, trying to build boost, etc, etc) that he didn't even jam it to the floor and got fifth. Now he has 200HP injectors and a drag comp to compliment it. He still managed to place fifth. I think it is a sweet pulling turbo. As long as the day is not 90+ and humid it still makes a very streetable truck. This truck is his daily driver for a while still.

I think a Jacobs will work, Check out my readers rigs. Right where the actuator is at the front toward the truck its pretty close to the compressor housing, I dont think you will have an issue there but you might want to concider that. For heavy towing you might want to get the 12cm housing, its a little tighter for quicker spoolup and to help cool down those midrange temps, where you will suffer is on the upperend of the fueling and RPM scale with EGT's.
RE: Super Phat shaft 66
Just wanted to say congratulation to Justin he dynoed 527hp no correction factor. Good numbers! Now just need some of our Stage 2 Injectors and up you'll go. Thanks to all!

RE: Phat Shaft 66
We try to satisfy. If your looking for a high performance turbo NOW is the time while the TDR special is still running. If and when we run low or out of parts then the special will go away. Thanks 1-800-955-0476

Well thanks for posting those pics. While it looks sweet, it's crazy close to the stock shock mount. I KNOW it would never clear my beefy KORE shock tower. Looks like I'm still on the hunt for a solution. At this point it's looking like custom twins may be the only answer. Congrats on the install, glad you like the turbo!!
Lightman,
You can always re-clock the housing a tad (thats what I did).

Well... thanks to mattymac, JVolpe, and JWilliams3 very persuasive PM's I got myself a SPS 66 too 
. If "port-and-polish" was in the dictionary, then a picture of this turbo should be included. II has really done their homework on this, including such details as the shorter compressor housing to get a straight shot to the intercooler (no filter box trimming) as well as a machined 2. 75" compressor outlet so the stock hose can be used without stretching. Interestingly, they do have an ex-High Tech Turbo employee working there who actually built my old HTB2 62/14 (2nd one on 12/4/04 according to the S/N).
IMO I have no issue with laggyness on this turbo just running with injectors and box off. Spool-up is RIGHT NOW, but I don't know how much of this is due to the cam. The injectors are nice too. Before we swapped the turbo, I went for a test drive and there was no black smoke - box on or box off - only a haze like a stock truck. The previous injectors felt like they bogged the motor down with fuel and did put out the black smoke with the box on only (maybe this was the start of my injector plugging problems).
Anyhow, here's a cut-and-paste from another thread with my observations:
I was just at Industrial Injection the past 2 days getting an injection problem fixed and I also ended up trading my HTB2 62/14 turbo + some$ for a SPS 66 turbo as they were really, really interested in the 2 piece housing on the HTB2! I'm not going to comment on the price, but it was a deal I couldn't refuse.
IMO there is no comparison. With just injectors and box off, the turbo spools up faster than the HTB2 62/14 (qualifier: but this might have been due to my previously majorly carboned up DD3 injectors they replaced with their 3-Flows). While the boost gauge may show minimal boost - press the throttle and hold on - as in breaking tires loose in gears I've never done that before except on wet roads! Cruise EGT are similar to the HTB2 at similar boost, but at WOT the EGT are about 100-150* less with only 250 miles on it so far.
Edit: with previous HTB2 at 5,000' with 100 HP injector + very mild pressure box (VA C3. 1) on 100%, EGT hit 1250* WOT with the trail of black smoke. With SPS66 and similar combo EGT hit 1050-1100* WOT and everything is clear. Turbo is not broke in yet either w/ 300 miles. I'm putting the Juice/Attitude back on today - let the fun begin!
I got turned on to the SPS 66 after I drove a buddies truck with a HTB2 SP66 a few weeks ago. I was really impressed with how his truck drove at the time with only 100 HP pressure box level and TST off - spooled great etc. According to him, he wants to upgrade his SP66 to the SPS 66 based on his research between the turbos. Since I was at II already and I corresponded with a few TDR members who had recently bought SPS turbos with rave reviews, I just decided to go for the SPS 66. Also, when they pulled my HTB2 turbo off and laid it on the bench next to their SPS 66, the custom machine work is a work of art - as in not much on the HTB2 versus a considerable amount on the SPS 66 including the little details such as the boost elbow screw-in depth into the compressor housing.
Also, when you decide to get the SPS turbo you should clarify which type of downpipe you have. I have the original HTB2 turbo version down pipe with the angled, flared edge. The SPS exhaust housings are machined down from this version to the stock, flat face type version. So I ended up getting a SPS 66 without the end machined to stock type. This is why my visit there ended up being 2 days!
(Also, in the 2 days I was at II there were 2 guys that came in wanting to upgrade their SP66 to SPS66 too, FWIW. )
I've had nothing but good luck and reliable performance with my old HTB2 turbo, but the SPS 66 definitely raises the bar - at least for 3rd gen single turbos.

RE: Stage 3 Injectors
We are currently out of stock but we have received some cores lately and should have them ready to go in 2 days. So if you are ready then we should be good. We know you will love them.

Does industrial injection offer any smaller turbos than the 66? My buddy had an HTT with a 66mm compressor wheel on his 2nd gen which surged quite alot, especially while towing. Now he has a 3rd gen with a hot juice and an ez while still running the stock turbo. He is shopping for a new turbo but not sure what to get. He likes the numbers the IIps66 puts out but is afraid of surging after the last experience. Any suggestions? Maybe 62-64mm compressor wheel instead? What housing size? Maybe the smaller turbine wheel was partly to blame on the HTT turbo?
BTW, old truck was a 6-speed 3. 54 gears, new one is auto with 3. 73 gears and does occasionlly tow about 4-5000lbs

Big P,
I dont tow, at least anything you can actually feel, so dont know about while towing, but I have Hot Juice/EZ stack and I do not have any surging issues. Before the SPS66 there was now way I could turn up the HOT Juice above 100hp and the EZ above Level 1 and really have enough air. You could setup on higher levels and acutally see boost in the 41-42psi range, but you were not really getting usable power, not enough cooling at the higher levels. Just my . 02.
