Ted B.'s HTA3582 Twinscroll Project
Ted how would this HTA82 compare with:
GT35R with a T3 1.06 Twinscroll hotside
vs
T04Z with a twinscroll T4 .84 hotside
vs
GT4088R with a .95 Twinscroll hotside
I am considering one of these plus a Autronic + 1000cc Injectors as my next upgrade...
I want max power with min lag yet torquey and drivable streetcar.
Thanks

It will certainly make much more power than your 60-1 + .78 TS T3, but I suggest better cams and an upgraded valvetrain.
For your 2.3, so long as you aren't aiming for more than 700whp, I see no reason to use anything other than a HTA3582R + 1.06 TS T4 if you want best possible spool and transient response.

Ok, I'm just afraid of Lag as I am above 5000ft... so want to use the smallest housing I can to compensate for the thinner air.
The 60-1 on the .78 TS T3 only gets full boost at 4000rpm and makes 320whp on a mustang type dyno at 12psi... 91oct ; at 27psi it can make 420whp on the same dyno on better fuel and some timing... We tried a bigger 1.06 housing and the spool was like 5500rpm.
MY GT30R with the .78 TS T3 had full boost at 3500rpm and started spooling before 3000rpm - I am thinking the 35R or HTA35R with a T3 1.06 will spool better than my 60-1, not sure if this logical or not...
thanks again

ps. After seeing Teds progress I am sweet on the HTA35R with a T3 1.06

Sal,
Why don’t you think about a 35R 1.06AR TS or a 4088R. Both are similar except one does a bit better on top end….marginally! I have housing sises from 0.85 – 1.06 to see the spool difference and I can tell you that a 4088R can be a very very streetable turbo that will leave any 911 standing.
Look at what Johnny and I have done. There are two good examples setting the standard in SA of 450 – 500WKW daily drive cars running 4088R TS. One is a built 2L (mine and built for my 4294R) and the other a built 2,3 – Jimbos) Also the numbers we have are not directly comparable to the US figures. Most SA wheel dynos seem to read a lot lower!
If you have a 2,3 already and its decent enough, may as well benefit from that displacement and boost it. Depending on the headwork you have, 2 - 2,5bar is reliable on 95+ T&X, especially if you have water injection. I’m in SA end of Feb to refine Johnys tune as he wants to make north of 480WKW on my stingy dyno at 2,3bar, so you’re welcome to come watch. FYI - on a dynapack that’s about 520KW or 696hp at our sea level! Not bad considering peak torque at 4500RPM.
As the Autronic dealer for South Africa, let me know if you want one and I can always arrange. It’s a great ECU and I have built 3 Evo’s that smack the living daylights out of mega power Scoobs on the track ..reliably!

Thanks Pops, have been chatting to Johnny... very impressed with his setup and results...
Yes I'm keen on the 35R 1.06AR TS (If I can get it with a T3 housing I won't have to change the flange on my Manifold that will be a bonus)
but I am also considering the:
GT4088R with a .95
or
HTA35R 1.06AR TS
and
maybe even the GT3788R when its released haven't seen any results yet.
As always I would sacrifice peak power numbers for a good area under there curve with minimal power drop-off.
Will give you a shout when its time for the Autronic.
Thanks

OK
Some closing thoughts

Some closing thoughts
- 3788R is a poor turbo - mismatch of note and I think everyone cried for it and now Garret released it for all to try! Presure ration and flow of the turbine vs teh compresson is worse than going with a 4088R and a 0.85 AR turbine housing. Its availabel if you want at $1 790USD
- T3 Twin scroll will choke the heck out of a 35R.....just make peace with having to either modify the manifold, or get another one. The housing for a 1.06 T4 may look large to the eye, but mathematics show its actualy a good fit.
- HTA is overrated when you going twin scroll. Its like the cherry on the cake...doesent add much substance, just a nice to have. For the non TS its a good addition.

This is quite a build and from reading many of Ted B's posts around the forum about this setup it looks like this is definintely the way to go. Awesome work man I can't wait to see what kind of numbers this puts down. There are many non believers of the T4 TS setup on an HTA style turbo but it's great that someone actually has real life feedback and the willingness to try new things.
I have a PT67R right here with a 1.00 A/R TS T4 turbine housing. Someone just needs to take it off my hands and send it in for the HTA treament.
Anyway, we had two issues to resolve with my car:
(1) A fuel regulator issue of which everyone should be aware. A discussion on that topic is forthcoming.
(2) A boost leak at the Hypertune TB shaft - patiently awaiting a replacement TB.
Despite these aggravations, the car is real pleasure to drive. No large turbo deadness anywhere.

Ted waiting to see the results on your setup. i want to see how much quicker the ts spools compared to my set up. also to see if the ts runs out of breathe in the high rpms.
Ted- not sure if I missed it in this thread...who makes the 1.06 div t4 housing for the 35r? Was it machined to fit? Thanks for any input.
EDIT- is it the ATP housing?
