FP 68HTA turbo

[Bmxr152]

So i ordered the 68HTA turbo from forced performance. Ive read every post i can about it, but all i can find is stuff on english racings e85 car. So anyone that has the 68hta please give me some feedback about the turbo. Anyone have any dyno specs besides curt browns car?

Im not trying to talk sh*t but why would you make a post with all the info completely wrong especially knowing that owner/builder/tuner will end up reading it.

... sorry to everyone who read this thread about my false info in my OP, I was wrong about the way he controlled boost.

My bad.

All internal gates kinda of blow open surge is a whole different problem which I have not seen on 16gs yet.


2.3 is not one of the mods our record EVOIII 16g # was on a stock 6 bolt with 2g pistons 450whp 510 ftlbs. Mod path is very simple.

Know what you mean on pushing it the tune hard for 6hp. Did that with my EVO for the 522whp on Stock IX turbo. My 9.9 was a very pushed tune, but the normal 10.0 10.1 is not pushed much at all.

I know this is an old thread, but there's really no need to keep starting new ones.

I was wondering if some of you guys that are running (or have ran) the 68hta, could post more results (pump gas, e85, or other fuels). A quick mods list and boost level / fuel would be helpful. I'm interested in pump gas (91-93 oct), personally, I have access to e85. Thanks.

I saw cory's (gofer) thread, that was really inspiring..

I actually just picked one of these up and I'm about to get it tuned on both 91 & e85. My current setup is the turbo that the HTA68 replaced (FP 18g-6sl2) which died around 25psi. It did end up making 387hp/355tq with supporting mods on the same dyno and tuner the Gofer went with. In all seriousness, the HTA68 is a solid 400hp turbo with some sort of race gas. I'm chasing Gofer record with my HTA68 but I'll be happy with numbers higher than 400.
On a side note, i know there is generation changes between the early HTA68 and the current ones for sale. My friend has the newest version of this turbo (8cm hotside w/ 6sl2 turbine) vs my (7cm hotside w/ tdo5 turbine?) and said he would be willing to use my car as a guinea pig to see the actually difference between them (spool/peak HP & TQ) on the dyno. I just need to talk to my tuner and see if he would be down to do some scientific research without killing my wallet.
You guys can keep up with my build if interested here: https://www.youtube.com/user/daniel1997gsx

What kind of turbine housing are you gonna use?

 

[danielsl1999gsx]

I will be running the 7cm evo III hotside because thats the one i bought, however in the near future i will be dynoing both to compare (8cm vs 7cm)

You can't directly-compare the "new" 68HTA to the "old" 68HTA's results. The old model was made from a MHI turbo and used a TD05H wheel in a 7cm2 housing. Spool monster, but may be limited by turbine flow. Think of it like a TD05H 20G. The new 68HTA has a larger turbine and an 8cm2 housing....users are reporting slower initial spool, laggier transient response, but bigger horsepower numbers and better airflow production at high boost because of the increase in turbine flow.

 

[danielsl1999gsx]

What i want to compare between the two is to see if the new version is really worth it. I know a couple of guys have the older HTA68 and want to send it out to fp for the bigger turbine/housing conversion. However by comparing the two back to back i can hopefully put this question to rest. Does the slower spool and laggier response really outweigh peak numbers that it will put out compare to its older brother.

Guess it depends on what your goal is. I really like the way the new version performs.

 

[gofer]

I'm one of the guys running the older HTA68 that uses the TD05H wheel but (with Justin's help) fit a BEP 8cm2 hotside to it. I know the newer version of the turbo claims 51lbs/m whereas the older version that I'm running was advertised at 47lbs/m, but currently I'm logging accurately 51lbs/m out of the TD05H version. Prior to that, when I dyno'd the 440awhp at RRE, my logs were showing 47lbs/m which was expected...

I do need to get back to the dyno with the most recent setup but I've got it flowing 4lbs/m more with this setup than I was when I had it dyno tuned at RRE 5 years ago.

Keep us posted Daniel, I know you update your build thread but it would be nice if you started a new "HTA68 new vs old" thread to post that info in.

 

[danielsl1999gsx]

Yeah that is my plan Gofer. I just got the turbo in the mail today so i still need to get it on my car and what not... Ill start the comparison thread once i actually have everything installed and my tune/dyno appointment set.

 

[90laserRSfwd]

I also have the newer version. I bought mine sept. 2014, but didn't have a DSM at the time to install it. Early Christmas present.

I'd be interested in seeing the td05h / 7cm vs the newer setup
