    Is the 68hat still arguably the best street turbo for pretty decent power with not too much lag? Or has someone come out with a better "version"?

    If I'm not mistaken the 71hta is the replacement and spools a little bit slower but provides 51lbs of air.

    I think Fp is rating the 68hta at 49 lb/min and in stock appearing fashion, i cant think of a better sleeper turbo. Spool is quick and has great top end. Easily a 400hp turbo.

    I'm sure others will just tell you to get a 20g or an hx35 but IMO you won't find a better comparable turbo. Yes you will pay a bit more but it is definitely not a waste. Support the vendors that support our platform. You can never go wrong with Forced Performance. I'm currently running their 76HTA (Green XL) and couldn't be happier in regards to not only the turbo itself but also the experience I had dealing with them.

    Check out TurboLab Inc on FB. They are out of North Carolina, I think, and have been doing some crazy things and experimenting with different compressor wheels.

    They other turbos he suggested are legit but HTA stuff has really been most of the innovation in bolt on turbos in the comunity from what I can tell. I am on the fence with this myself being that I have an hx35 that needs rebuild, access to a td05 20g and I for some reason cannot shake the thought of an HTA68 or 71 for a quick spooling street car. Im interested to see what others have to say.

    Define "better".

    Sure you can fit bigger wheels behind a stock-appearing cover...hell I built what is basically a stock-appearing FP Green in the past- it's still on a shelf somewhere in the shop. The key thing to remember is that anything bigger is going to be laggier and will produce a smoother torque curve. The 68HTA is fairly small being nearly identical in spec to a MHI 18G but has the potential to outflow a 20G compressor.


    There is a newer billet extended-tip 20G wheel available from KTS which is 1.5mm bigger on the inducer and 3mm bigger on the exducer tips than a 68HTA, but nobody's pushing one of these wheels to the max on a DSM platform so who knows what it's capable of when matched to various turbine wheels.

    I have built a handful of stock-appearing 20G's using the KTS wheel mated to a TD06SL2 turbine because I truly feel the TD05H turbine is out of it's league mated to anything larger than a 68HTA compressor. The bad news is nobody's really given me any results on those I've built, so I have no clue how it performs in comparison to the 68HTA. The 06SL2 turbine upgrade does effectively reduce backpressure and allows for easier tuning with pump gas. The end result has a slightly larger compressor and slightly larger turbine than a 68HTA, and looks something like this:

    BilletTD06SL220G-1.jpg
    BilletTD06SL220G-3.jpg

    Does that mean it's better than a 68HTA? Well I suppose that would depend on what your power/spool demands are. :D

    FWIW my car has a Td06SL-2 turbine wheel, in FP's 8cm housing. Mated to a KTS 55mm inducer 76mm extended tip exducer all behind the TDO5H compressor cover.

    What's spool like on that monster Tyler? I thought you guys were using a td06h4 turbine?

    I'm making 15psi at 3500 on my lower limiter. Thats at 10:1 afr and 0* timing. makes 20+ at 4100. Its an auto car so it would be hard to compare to a stick. Plus 11.5:1 and methanol, no intercooler. So the setup is pretty specific.

    Doing some testing with my setup just these last few days.

    Stock 7-bolt bottom end - SMIM - Evo III TB - VRSF FMIC kit - FP exhaust manifold - BEP 8cm housing - HTA68 - FP2 cams

    19psi @ 3.8k // 30psi @ 4.3k // 37psi @ 4.7k

    I was logging 48lbs/min on the 7cm housing and stock 2g exhaust manifold running 28psi and I'm hopeful to get to 50lbs/min on the 8cm and FP manifold, still getting AFR's and timing where I want it.

    Nice thread im deciding on another turbo for the street setup on my car, that fp manifold should help out with that set up, I already enjoy my manifold on my setup, thinking about those fp cams as well too corey.

    Hahn Racecraft's S16G uses a 10cm2 T3 turbine housing - wouldn't the 68HTA make a bit more power maxed out with that and a T3 manifold, as opposed to the 7 or 8cm2 housing that it comes with?

    You'll probably make more but you'll add to the spool time kind of defeating the purpose of why a lot of people buy these things.

    Only if the existing available housings prove to be a huge restriction.

    Sometimes we get too wrapped up in the whole "more flow = more power" concept and we forget that eventually you'll reach the point where the compressor just can't keep up. It's the same reason you wouldn't put a .96 a/r T4 housing on a T25 and expect to run 10's....adding lag with no additional airflow benefit.

    I'm certain FP has done all the R&D and would offer the 68HTA with a 10cm2 T3 housing if it actually performed better. ;)

    the 68hta is a bad little thing. People have ran crazy times in full weight dsm's. for the sale price now I would jump on it

    my 71hta with a bigger wheel and same 05 turbine is amazing as well. I went 123 on only 22ish psi with supporting mods. I'm now spiking 33 and holding 27 at 7000 and have a few more mods. Im fully confident in close to 130 traps on a td05 turbine in a full weight 1g.

    the 6sl2 will be better on pump and i'm sure you can get a nice extended tip 20g with a 6sl2 built for a fair price but i have yet to see results for one of these. maybe there is a reason for that.

    I hate to ask a dumb question but is this on pump gas or e85 or something else?

    I am being told I should shoot for a hta71 over the hta68. I can get a tdo5 20g for a good price but I know after running holset in the past I may want more out of a DD. The HTA68 seems like it bridges the gap between the 16g and the hx35 in a bep. The performance out of the 68 is just impressive for a stock appearing turbo.

    Read my signature. :D Yes, I'm running E85.

    Since I've been running the HTA68 on E85 (March '08) the DSMer's I've known running 20g's, 50 trims, or HX35's in a bolt-on housing have ran similar times/trap speeds. With that being said, I can't comment on the HTA71 because I have yet to see a dyno sheet, time slip, or log from a DSMer running one. I guess it's because it's a fairly new turbo from FP?

    I had a 16g on my car before I installed the HTA68 so even if the HTA71 was an option back in 2008, I still would have gotten the HTA68 because it was direct bolt-on for me. Now, if I was running a t-25 and didn't have all the IC piping setup, I'd probably consider the HTA71.

    It's personal preference, really. I like the fact that when someone's looking under the hood of my car it looks like a basic 16g turbo setup with a bunch of unnecessary bolt-on's to support it. If you've got an HTA71 that wouldn't be the case...

    I hit 30psi at about the same exact rpm with a new 76hta red with a clipped td06h turbine in a 7cm housing.

    Very interesting indeed, I'm waiting to rumbthe 68 since I never got to run the 16g at the track this past summer but looking at flow numbers and results I'm getting pretty excited to see some times, i don't know of anyone has ran it on a 10;1 compression built motor either, I'm going btobtry to clock the compressor cover downward to eliminate the j pipe just to experiment lilk on another thread I saw, but it definitely looks like a fun turbo to be honest. The sleeper look under the hood is unreal.

    Yeah sorry I missed that my spanish isn't all that great and didn't think anything of that.

    See thats my issue with running the HTA68. From what Ive been told it seems like they only perform like that on better octane. I think it would be cool to to have a stock appearing turbo that makes more power then one like you said. I guess its just not as important to me although when you pop the hood and have the monster of a hx35 sitting in there but not doing what its capable of being in a bep housing well that kinda sucks too LOL. Like you said all preference. From what I understand the HTA 71 can basically do what the hta68 does but on pump gas and nearly no spool sacrafice. Bolt on turbo that can make 400whp with great spool times, its just a matter of coming up with the price tag.

    Like I said, I can't comment on the HTA71 but I wouldn't be too confident you'd see 400awhp on 91 with it either. My car put down ~360awhp on the HTA68 but I was knock limited and could only run 24psi and 8* of timing... You might be able to get away with more or maybe even less, every car and setup is a bit different even using the same turbo.

    I get what your saying. So basically that turbo would make what you are on pump gas and maybe a little more depending on what mods there are. We roll with 93 octane around here haha :hellyeah: If e85 was more abundant Id probably run it in at least 1 of my cars but I gotta drive a half hour to 45 minutes the other direction from where I work to get it. Its not worth it to me.

    Even without much real world data on the HTA71, it does come in a anti-surge compressor housing and my HTA68 surges in WOT.

    Yeah I picked up on that but what does it help with, the intake air coming into the turbo or preventing back pressure from going to the turbo? Im just really trying to decide on the next choice of turbo like the OP and I was looking at this exact turbo. Ive had 4 different Holsets and I love them but only on 9:1CR or a 2.4L to make up for the lack of bottom end. I currently have an hx35 8 blade I could put into a .55 bep housing and make decent power on the street I just would have to make a lot of changes right now and im not sure I really want to do all that. Ill probably spend the same money buying the mods needed to support the turbo as I would just buying a direct bolt on turbo.

    I picked up a stock 2g gsx and I have a bad habbit of over building when it comes to the turbo and going t3 and I love the power just not the power band so im trying my best to back it down a notch this time around so I enjoy having low end and the power I need for daily driving and stop and go.
