After some discussions with FP and JuxMX I may have had a blown oil seal on my turbo which would cause some further problems with my paticular setup as far as spool goes, It has been sent out for examination/rebuild and I will update you guys when I know what the cause is. In the meantime I will be upgrading to a set of FP2 cams and finally getting my headgasket/ARP head studs in and will be able to turn the boost up to my desired goal of 25-28psi, I'll see how the 16g holds it, and because I have this kind of time on my hands I will be switching back to the v2 68hta to see how it likes high 20s for boost rather then it sitting right around 20psi.

Not that this is a great measuring stick but I always found 1st disappointing in the 68hta, Id stomp on it and nothing happens until I'm so high in the RPM range I have to shift VERY quickly after it actually hits boost.. right now set at 22psi in the 16g If I stomp on it in first the car scrambles for a second when it hits boost with a brief amount of wheelspin and I'm grinning ear to ear as I take off.. Again though, I am biased towards a "torquier" car then I am towards a top end car. The 68hta felt stronger on highway pulls but after reviewing my logs It's hard to say because Gofer was right about my timing tables, Had I run a modded 1g table to begin with in the 68 my findings could have been vastly different.

I'm not sure the results of 20psi on the 68hta is what I'm looking for

I agree with Brett 100% If you are keeping the boost low I would avoid this turbo, I'm flowing nearly the same amount with my 16g right now (got my boost leaks fixed and logged 39lbs a min @ 22psi) Search for the original or stick with a 16g variant. I won't make any other recommendations as my experience is limited to stock frame turbos.

I see full boost at about 4,200 on stock motor full boltons and E.

That's a little bit slower then I was boosting, are you running cams? I thought e85 helped spoolup a bit because you can get more aggressive with the timing cruve

GST with PSI said:

If your end goal is 20 pounds of boost, you should have just stayed with the 16g. You'll literally be downgrading by running the new 68HTA on low boost.

People need to realize the new 68HTA is a completely different animal than any TD05H variant. Unless you're shooting for 30+ psi, this turbo is not for you.

Like I said, that's what I'm starting to realize. Especially with this new 8cm housing. I was on a "conservative" tune with 20psi on the e316g. I guess I'm not too sure where my psi level will end up after tuning. And I'm also trying to leave myself some room in the turbo, with upgrades like cams to follow next year. But I'm wondering if a different frame turbo would yield better spool response, with leaving the same potential for higher hp with increased psi.

So to sum things up a bit, the newer 68hta, spools a few hundred rpm later, because of the larger turbine wheel and 8cm2 housing. Only trumps and EVO 3 16g in the higher boost levels (say 22+ psi?). That's what I'm gathering from the last 10 pages. This turbo is so close to the FP green (54 lbs min), that one could assume the only reason to chose the new 68hta, over the green, would be to retain the td05h compressor cover (stock appearing).

I think that about sums it up, except I'd say higher 20s might be more accurate, 25+
I'd say the difference would become quite noticeable and any issue with lag might fly out the window. I just upgraded to ARPs and a new headgasket this past weekend so I'll post up a log with my 16g at higher boost levels and when I get my 68hta back I may swap over if I get bored come winter.

Seems with the v2 they are moving this closer to the FP Green. I will be trying this out, since I've bought it and installed it on the engine (now I just need the engine back in the car, ).

Also, there was someone in the past pages looking for Dyno results of this turbo on stock longblock/stock cams. Those will hopefully be posted up in the coming weeks.

Never even noticed you were from my neck of the woods. were you at STMs dyno day/open house?

Yes, I DJ the event every year. Just didn't get a chance to get any of the cars there this year.

Out of curiosity, what would people pay for a mint HTA68 V1 with a 7cm turbine housing, TD05H turbine wheel, and FP 18psi actuator? I'm debating whether it's worth holding onto mine or moving to the current one, as I'd be chasing a max effort stock appearing setup, and there might be some gains up top. I had originally planned to keep what I have and make the most of it, but from the comments I'm wondering if the old one's worth more to some people than the new one.

i wanna know where i find info on these turbos? I've been sorta out of the loop sicne the holset rage kicked in and all the HTA and such compressors i hear about i can't find because i don't even know how makes or sells them (god i feel like a nooob)

I'd imagine probably a bit more then a 16g.. 550 or so in good condition? with the release of the v2s and the sale.. I would imagine it drove the price of the previous model 68hta's down with it as well, It dropped demand for 16gs hard as well, Why pay 500-600 for a 16g when you can pay 100 more for a larger, brand new turbo? Same rule still applies as the 68hta is still a low price.

That sucks, I mean it's awesome that you DJ it but I'm sure you would've liked to check out some of the cars there, I was amazed I saw about 10 dsms locally, and my friend showed up in his almost identical white 1GB eagle talon so it was nice to park two side by side, even though not many people seemed to know what they were.

Not everyone wants a larger/laggier turbo. The EVO3 16g strikes a good balance between spool, response, torque, and power. I found the torque almost scary above 28 psi. Running that turbo below 20 psi was almost a crime, it's such a different animal at higher boost levels. For $599 when FP had them on sale, they were hard to beat bang for buck. I wish I had gotten one from day one but I enjoyed the hell out of it while my engine and trans lasted. It's a shame they are over $1100 new but given the state of ebay knockoffs and cheap DSM owners, it was inevitable the low prices wouldn't last.

Agreed.

In addition, I'd say hands down the best bang for the buck "upgrade" is the bastard 20G, IMO. You can build one for a few hundred bucks, gain a few lbs/min up top, and still keep your 16G-like response.

To date, that's still my favorite turbo I've ever ran on the car.

Seems like a lot of folks of purchased the 68hta (from the beginning stages V1) up to present day, but I don't see many results posted (searched threw a few threads google brought up this morning. Where's everyone at!

I hope this turbo preforms well. It will be on my car soon and the boost will be set around 25 to 30. I don't daily drive this car. Mainly a weekend warrior. I will take some videos of the trubo spooling on the car and post them and some drag videos. I run 264/272s so i am not sure what rpm the boost will hit. If i do try another turbo for the street im going to see how much i can get out of the small 16g.

FWIW: I had genuine HKS 264/272 setup. Also had the v2 68hta. Sold the cams (was going to switch to GSC S1's. Ended up selling the 68hta, as well as the car before it happened). My thoughts: The 264/272 setup added lag but didn't really pull that well after 6,200 - 6,400 rpm. Car was on Link v3, SD, had all the supporting mods. I personally didn't like the 264/272 setup, hopefully you'll have better luck!

Honestly if I were to build another setup around the (v2) 68hta, it would be GSC S1 cams, along with a JMFab street or race (not drag) intake manifold with the "curt brown" extended length runners. 63mm T/B, a good FMIC, and external wastegate. Pump with 100% meth or e85 (boost in the 30+psi range) 2g head, 9:1 compression, with a good shifting trans and twin disc clutch... Just my 2 cent's though.

Bumping this back up there. I picked up one of these during the black Friday sale. The car has been down this entire season, just got it all together and scheduled a tune at Boostin next month. I'm coming from an evo 3 that I loved, they got me with the sale price, I was really happy with the powerband I had. Like others in this thread I'm almost regretting it before even running it. However, of the results and reviews I've seen of the v2 nobody has really had a setup like mine so I'm holding out hope. Quick overview of the setup:
Stock 7 bolt longblock
GSC S1
Evo 3 intake mani ported by Curt Brown
FP exhaust mani
Punisment o2 w/ Tial MVS
All hotside parts were thermal coated inside and out by FFWD

I won't mind if the spool is a little slower than the evo 3, as the torque hit made me question drivetrain longevity.
I think what this turbo would really benefit from is an evo X turbine housing. I don't understand how twin scroll technology hasn't trickled down into the dsm marketplace. The only time I see it in a dsm is on some t4 setup or something. If FP made a cast manifold that allowed you to bolt on a X turbine I'd buy it in a heartbeat.

Had mine on STM's dyno Sunday night, with some of the other shootout bound cars. I had a VERY conservative tune done at 21 psi. Let me say that I'm on a stock longblock, 181k miles, pump 93, and stock cams. I just repainted the engine bay, and cleaned up all the wiring, so I didn't really want to risk not making it to the shootout.

Even with stock cams, I'm seeing full boost right around 4K Rpms. The pulls feel a lot stronger all around, even though I am sort of missing some of that torque.

I still have plenty of room to go (as long as my motor wants to play ball). After the shootout I plan on upping boost and maybe doing an e85 tune, since I'm already set up to handle it. A nice streetable cam set, will probably be a mod for next year.

I'm not far behind you on fp2 cams at 26psi, I'm still dialing the 68hta in but I think I'm about 4100-4200rpm. What did you put down if you don't mind me asking?

I had my GSX there a couple weeks ago getting it dynode with the 16g, 292whp. I've got to finish tuning it before I get back but Ecmlink says I'm making roughly 80 more hp then my 16g logs, so we'll see! I wish I could go to the shootout with you guys. I'm definitely going next year!

What kind of power did it make, and can you post the dyno sheet?

Well I was going to get this turbo but plans changed. Liking the v1 better after talking to a few people. Holset it is just grabbed some stuff plus room to grow.

***DISCLAIMER: I knew I was going to get asked how much power it made, haha. The only reason I didn't post it was because I'm such a baby when the thing is on the dyno, and really pleaded for a safe tune. I have FULL faith in Emery as a tuner, just not in my 181k mile motor. The car didn't have any knock whatsoever though. So I don't think the numbers are very indicative as to what this turbo can put out with a stock setup, even at the same 21psi. These results should not be taken as any evidence as what this turbo is capable of, or the tuning abilities of STM (not that it's even worth saying since they have various 800awhp+ vehicles already). Cory (EvilTSi) and Austin were already ragging on me as soon as I pulled the car off that I've wanted more power, but I'm afraid of this thing blowing up! After the shootout I'll be back on the dyno though.***

But.... Since we are putting numbers up, I believe it put down 283awhp and 230???tq. I'd have to look at the sheet again. 300awhp+ was honestly just another pull away, but again, shootout is the goal first. You can feel it in the pulls that the turbo really hasn't even "waken up" yet at 21psi .

283 on STM's dyno is nothing to sneeze at even on a conservative tune. I wish I could have Emery tune my GSX but I'm just too cheap to pay an extra 500 for him to do it.

Don't forget that this turbo doesn't wake up until 24-25psi, so you're in for a treat if you plan to turn the boost up!

You've definitely got room to grow if you decide to. Thanks for sharing, and I'll be on the lookout for those purple wheels at the Shootout
