I'm looking to do a whole new build. I've been on the forums for a while with over 1k posts. I've done my search and cant seem to find a TS35R vs HTA35R thread; all i find is single scroll vs HTA or TS vs single scroll.

my question is very simple and i would like some professional insight. I'd like to see input on people who have done both of these.

My current setup is a Single Scroll 35r. I make roughly 460whp but the lag is not my cup of tea. I'd like to be over 500whp on pump and over 600 on race fuel.

No comments by people who have neither please UNLESS you have a friend....

 

Ya have a basic 35R on my car and My Friend has the HTA 35R and all I can say is that HTA35R's kick *** His spools up much, much faster The HTA 35R has my vote and will probably be one of my next upgrades If you are comparing a twin scroll to a HTA I pick HTA

 

Got the HTA35R on my car, just love it when the turbo starts to spool
go HTA

 

I have a TS HTA35R on my car, right now. I used to have a single 35R on the car. If you want absolute minimum lag and best possible street feel for a turbo this size, get TS HTA35R. It's the best of all worlds. There is no better way to do it.

 

I wish more people had video footage of they're gauge cluster showing spool up on both TS 35 and SS HTA 35R

 

What rpm would you guess I will see 20psi of boost on a TS HTA35. The motor is a 9.5:1 2.23L. Thanks Ted.

 

I see 20 psi right at 4000 rpm with a 2.0L. Yours should be faster. You can't ask for better than that from a 700+whp turbo.

 

i too have a twinscroll hta gt35r with a t4 1.06 hot side and let me tell you it spools fast. 20psi by 4k rpm.

This is my twin scroll hta gt3582r with the t4 1.06 ar turbine housing on a stock motor. makes 200whp 220wtq by 4k rpm and 20psi by 4k rpm

 

TS HTA35r,

best of both worlds, no question about it.

 

is the TS HTA35R gonna flow less then a SS HTA35R up top?

 

No one can answer that question definitely just yet. At the present however, given what has already been done with TS T4 turbine sides, there is no indication that a 1.06 TS T4 is too small for anything short of 900whp.

 

If thats the case why aren't we seeing any TS HTA86 combinations? I would rather run the 86 than the 82, but I was under the impression that the 1.06 housing would be too restrictive to make use of the top end power. Maybe I'll be the test mule.

 

thanks ted, ive read up on your following TS HTA 35r, good deal, thanks guys

 

Possibly because most present TS cars are primarily street cars, and the HTA82 (a 700whp turbo) gives quicker spool response.

 

Ted do you know the surface area of the volute on a T3 .82 housing compared to a a TS T4 1.06?
