i am building a 2.3L storker and was wondering what peoples thoughts were on the 68HTA turbos as i am looking for a new turbo and like the stock turbo look. Thanks Justin
 
i've read a few user reviews on the american toona sites (dsmtoona,dsmtalk), a quick search should help you out.
 
There's a lot of discussion for and against this turbo, a lot of it seems to be people against but with no real reason than that one person hated it for its all forum hearsay (as what i'm about to tell you a summery of my forum reading)


What i have read though is that it runs a wheel that is 68mm at exducer (hence the 68HTA name) and is 53mm on inducer, so 1mm bigger than a 20g wheel.
It is a billet wheel, meant to help spool.
It is the same wheel but reversed as in the FP "white" turbo they released before for the later evo's.
"Apparently" these wheels spool same as stock turbos (but people say that about a 20g as its only a reasonable increase in lag) but more top end.
The weight of the billet wheels is meant to help it.



Now the reason so many hate this turbo is the E3 exhaust housing perfectly matches the compressor wheel in flow, so a larger compressor wheel with the same exhaust wheel wont be able to flow any more. So why have a bigger compressor when you choking the motor with the exhaust side so many claim. Mind you the american soom to love running these turbo on the choke limit, not trying to get say 20psi with the most flow an efficiency, they really look at the choke limit of the turbos.


FP claim 47lb/min flow but so many people say with a stock exhaust side its impossible.
But the Americans run the E316G's till they are on fire all the time. so they are running the turbos to the choke.

What i'm more interested in personally is will a 68HTS flow more, and more efficently at say 20psi.

Someone has also posted that they have spoken to a bloke called Aniel, (who's name iv'e seen come up before, worked for FP from what i gather), about the hot side and he said the exhaust wheel is the same size as a stock E3 but different design and mean to flow more. This would mean the turbo can make more power, but guys seem to be getting 40-41lb of airlfow on 21psi. Not 47 as they claim.


There has been 2 people i can see that have supposedly shown an improvement with the turbo but the tests compares the the E316g isn't rigorous. They've had great results but its too variable.

P.S im really drunk (its my birthday, nights over and i cant sleep lol) i hope all this makes sense its just what ive been reading as i want one of these to.)

Im putting links int he next post.

Taken form link forum.

I asked him about sending just my complete center section in for the upgrade and he said it wasn't as "simple as just tossing another comp wheel on the mitsu center section."

He went on to say that other things needed to be done and there were things that "needed to be done about the turbine wheel" and "things with that were "different"" as well.

He wouldn't give me any more detail about the wheels than that. Just that it would be easier for me (and probably them) if I purchased one brand new instead of doing an upgrade. He made it sound like the 68hta is 95% different from a regular e316g, other than the housings.

There are some rumors on the subi forums that the turbine wheel is identical to the regular td05h wheel except it's hollow and therefore much lighter . I don't know how well that would work out in the long run if it were true, but hey, stranger things have happened

Did a quick search for the threads i been reading. I'm sure there's more info i got side tracked on.
The main thing im thinking is i probably wont max the exhaust side out, (there figures on what flow rates max out a TD05 housing and TD06 housing for eg. you just have to find them. Not often published, they are on the forums)
So if i can make more flow a a decent boost of say 18-20psi and make it cooler its got to be good. But trying to figure that out is fun....


This bloke went from pump fuel to E85, with a E316g, then with the same setup to a 68HTA, showed a great improvement then everyone look at the logs and the air temp accounts for some of it. Still leaves a bit left for the gain of the turbo. Also the logs are different, some are goin 1-2-3 then others are rolling 3rd. so the spool is hard to compare.
If you dont have ecm link and cant read his logs, read the second link i posted as he summarizes it all.

This bloke ran a 10 with it. But then again the yanks can run like a 10 or 11 second quarter (cant remember) on a 14b with a bigger rear housing.

Read this if you want to see what they run on a 14b.

To answer your question you probably looking at a turbo with a less restrictive hotside as you have the capacity to spool it compared to a 2L.

With the whole E316g vs the FP turbo they keep going on about the extra cost of a few hundred bucks, as shipping is stuff all if you live there, but we have to pay so much just to get either turbo over here, the difference then isnt so great.
 
I run the same size garret compressor wheel with a modified exhaust housing,cut back exhaust wheel, modified wastegate port and flapper and saw 272 on 18.5psi on mine with very good spool
 
Thanks heaps for your input guys! I probably should have mentioned that i am not goin for all out power as this will be a daily driver still. So i dont want a laggy turbo just something that will spool nice with good useable street power.
 
Mine arrives on Thursday. It is for a built 2 litre.

Will take about a month before it is all tuned up.
 
Do i need to order the "2G DSM Install Kit for 16G" aswell for this turbo? or can i just use all my current water and oil lines?
 
It is sitting on my computer desk at home.

I bought the intake pipes and adapters. Will just be using my standard oil and water lines.
 
My next package just arrived. 4 days from maperformance to brisbane. Fantastic service. It took longer for forced performance to deliver it to map.
 
can you buy the j pipe separately? i couldn't find it on their site. Does it go back across the top of the exhaust manifold or does it take the standard route? And which adaptors did you get?
 
Hey what size does the flapper come stock? do i need to upgrade it? And does the exhaust housing come already relieved to allow the flapper to open fully? I have ordered the turbo but have about 2 weeks before it gets to MA to have exact details sorted out. I am having the exhaust housing ported and ceramic coated before he sends it over, so just wanna make sure i don't need to modify it after it gets coated. Thanks Justin

Mate it would have to be the upgraded 34mm flapper MINIMUM for that turbo......Let us know for sure when you hear back from them!
 
on some of their turbos FP state they keep stock waste gate size and flap to aid in keeping the boost up, rather than ported and 34mm to help keep it down. So i would say it depends how you plan to use the turbbo, ie. how much boost you want at minimum, and also how hight you want oto go.
Also the larger flap can get blow open easier.

Also, porting the housing to allow the flap to open fully wont do anything unless you have more travel in the arm of the actuator.
On my 16g, i started to doing this on my turbo but stopped and blew the actuator open with the air compressor, its the amount of travel it has that limits the flap opening more, not the arm holding the flap hitting the housing behind.
