So is mine. What does that matter?
I believe the .84 housing is just to small. You ell Spool up fast yes but your topend will suffer greatly. Both the 6262 and HTA have a 62mm turbine. Your going to choke the crap out of it. And if you plan to push it to its limits then your asking for even more problems. I ran every turbo I listed on a stock engine except the HTA86 and the 6466. My engine spit a rod just driving down the highway at 55 mph. I was just driving like a normal person to so I can't say its bad for a stock engine setup. But why would it be?
My 6466 with 1.15 and STM 650 cams spools up actually the same as my HTA 1.06 with smaller BR BF-272 cams. The 6466 is making 140 more hp the the HTA did.
nd no one and I mean no one should ever use the ATP T4 1.06. Been there on 3 of them. There junk. Use a garrett 1.00 or any PTE housing.

Here is a picture of both style ATP housings:
This is the original Revision 1.06 housing:
And the newer Rev2:

Sorry to hijack the thread, I'm looking for options to get my auto 1g up on the converter quicker and switching to a T4 twin scroll kit sounds like it will help.

the new housing def looks better then the old one BUT compare that new one to mine.
yes mine is ported but just the overall hole casting is cleaner, and way smoother inside and out.

A T3 .78 on a 35r is possibly the worst turbine housing to use imo. It's much smaller then a T3 .63 non twin scroll housing.
Stay with T4. Don't be afraid of the "bigger number" it will only benefit your setup in twin scroll. Unless your looking for maximum spool up but your gonna be completely dead up top and generating a lot of heat.

I agree with Dan as well on the housings, bigger is better. Remember the turbo will spool like its 60% the size of the housing so a 1.15 spools like a 0.68 T4 single.
So you think going on stock block ,using fullrace t4 ts kit,with a 0.84a/r t4 twinscroll housing 6262 turbo is not a good choice?
Will be better for spool and power use a hta 86 in 1.06 t4 ts ? any ad/disadvantages to use hta 86 1.06 a/r instead of 6262 0.84 t4 ts on same car ?
Thanks.

At 27psi we saw 34psi of backpressure with the 0.84 TS T4 on the 6262 with a 2.5L motor (non Evo) on pumpgas. So at that point the top end would die off as head pressure in the turbine housing is sapping energy to the turbine wheel.
We have a 2JZ customer that has this housing on a 6466 but we havent got everything setup to log backpressure on this combo. Once we have that information I will post it somewhere for all to see...probably the Twin Scroll thread.

The 0.78 T3 TS is the worst housing ever made. It was only ever meant for diesels and even then lame diesels. We have seen it exactly once and it was so restrictive I think it hurt spool.

I think Aaron is referring to the divided housing 60 / 90 rule
Spool like an open housing 60% its size
Make power like an open housing that is 90% its size
so the divided 1.15 housing will spool like an open .69
and will make as much power as an open 1.0

John-
Yeah 0.69...I forgot it was an 0.68 I actually compared it to on the dyno.
Dan-
What Johnny said.
el.guerrero-
3586 whomps the 6262 in spool housing to housing, motor to motor. I have a 6262 car that didnt make 20psi until 5300 on a 2.0L and a 3586 that made 40 at 5300 (made 20 at 4700).

and about hp for the same setup and boost ? 6262 or ht86?

so what would be the best ar choice?? im thinking of switching it to a 1.06 atp twin scroll t3 housing or should i go with the .82 twin scroll?? my car will be daily driven so spool will be a factor
damn so the .78 is really that bad... i thought about it too when i saw how small the housing were
