Forced Performance Hta Turbos

[34GeeTeeTee]

So where are these genuine T4 divided rears for GT35's? I can only find genuine divided T3 or crappy T4 divided ATP housings?

I was saying last night at our SAU meeting that someone was chasing a T4 rear... It was you I think Lithium had a heads up on where to find them?

Dumb - I went to get a link and realised it was only T3 divided, not that it should be a show stopper - but T4 would be more ideal due if nothing else to the commonality of T4 Divided "things".

I called GCG and apparently they only have non-genuine T4 Divided housings to suit GT35's.

Wouldn't recommend using them if you intend on pushing it at all

I found some T4 TS housings for the Ita3582 I'm on my phone will post link when i get my laptop they're proper garrett housing aswell

My mates Evo has run a few twinscroll HTA Turbos.

HTA3582R with 1.06 A/R Rear Housing - Made 450kW

HTA3586R with 1.06 A/R Rear Housing - Made 500kW

Difference is about 2-300RPM in spool.

The HTA3586R is the BEST all round forced performance turbo you can buy unless your running really big boost like 40+psi. But under 40psi, the HTA3586R will be more responsive and make similar power as the HTA3794R's.

I ALMOST went to a HTA3586R. But just didn't due to $$ that I was spending elsewhere on the car..

On a pissy 2 litre youd be right , on a Rb30 , the 3794 should walk away easy on less than 30psi i would have thought

I'd love to try a FP4294 or 3794 on a sohc, just the normal garret 4294 was a very good thing with a auto and

small 8.5 inch torque converter

cheers

Yeah I reckon! The new Super94 (which basically outperforms the 3794/PT6766/pretty much any 67mm turbo in spool and flow apparently) is actually for sale for a REALLY reasonable price considering what it is capable of, here's hoping there are other turbine housings available on request for the bigger motor guys as the .85 seems a little small - though the Boostin Performance DSM trapped at 177mph so it would have to be putting out near >1000hp with the thing, so maybe the flow is suited and conventional wisdom could be overlooked in this instance:

I'd expect it would be totally streetable on a 3litre - imagine of street/drag weapon something like that could be?

here the link for the T4 TS housings for the GT35R 1.06A/R. I think the A/R is a bit big for me because im just chasing 400kw with something with reasonable response.

They are not very expensive aswell

[Lithium]

Looks like an ATP housing, we were playing with a BW S300SX 8375 and a GT3582R (with ATP 1.06a/r T4 TS) housings a while ago comparing the general turbo stuff and there was a definite difference in quality etc - GT3582R on the right:

[B-rice]

are ATP housings that bad, i guess if you polish it inside and clean it up a bit. Wouldnt it be a good housing

[Tonba]

^ I think its got to do with the casting process and quality of steel used.

The Tial housings dont seem too bad...seem to flow + spool better then the traditional T3.. not TS though..

Yep - that is my understanding too. Here's one a 1.06a/r one from a E85 guzzling S15 race car from here which demonstrates what concerns me:

[Tonba]

Wow.........

[34GeeTeeTee]

Top Quality right there!!!

[C BOMB]

Anyone managed to find the T4 twin scrolls for the HTA3582 i would probably just bite the bullet and get one.??

Thats the ful unit though im trying to source out a housing and maybe would make it cheaper because $2269. Is a lot and its not proven on RB25 though it has some serious potential packed

You know its going to make insane power and lag will be very little in comparison to equal sized turbos, the results would be the same sort as mine just on a higher scale!

the price is what is holding me back but if i get a fat tax back this is what im getting. if its not as i like resale shouldnt be hard with a few hundred off the price

Depends on where you want to compromise and what you think you will get the most reward from, you can definitely save a reasonable amount of money and still get respectable performance - however with this there is less risk you are going to look back and think... Maybe this could be better, but now I have spent the money.
