So what the hell do I do? I'll leave their names out of it because that would just be wrong so I'll just give you some of the answers:

First off I want to buy the Twin Scroll HTA35R setup from ETS. I decided to ask around to see what people thought. Tom(ETS) obviously stated in his thread that it was only made by request and hasn't been "Proven" so no big deal there.

Then I ask another Shop about it and they say "HTA" is crap and Twin Scroll with a basic 35R is best.

Last one tells me that he hears "HTA" is better and not better but couldn't say either way. He did say that he doesn't really like "Twin Scroll" for the street but didn't get into why.

These were all BIG BIG names here on EvoM and I just don't have the convience of an abundance of money to try all of these out.

This is the single biggest aftermarket purchase of any Evo owner...usually. So I'm concerned because now I have the money and don't know what to do. Opinions would be appreciated and some hard numbers would be even better.

No I didn't give an "Other" choice on the Poll because I will be getting the 35R kit. This will be a daily driver with occassional Drag use.

 

I see votes but no comments. I'm sure somebody has a good reason why they picked. It's not like I'm asking which wheels are the best looking. It's a matter of performance, not style.

 

no offense but it is a silly question

obviously the twin scroll hta35r is the best hands down... no one on this forum will dispute that fact. it has the most hp potential (over a 35r) and the quickest spool over a "basic" kit.

The real question is does more HP potential and better spool justify spending more money?

 

No offense taken. You're saying it's the "Best, Hands Down" but nobody has proven it. I'm not argueing with you because that's exactly what I want to buy. I think the ETS Twin Scroll is very affordable and would make your power/dollar question easily answered in my opinion.

 

^^^I agree. You throw some prices out and this question becomes easier... it sounds to me like you want bang for your buck.

 

ETS Twin Scroll HTA35r setup is more than a turbo kit. I would hang that **** on my walls or put it on my dining table (if I wasn't 19 and didn't live with my parents). I can not give you any hard facts as I know Tom just made one for a customer quite recently and I'm not sure it has been dyno'd. In theory, it should spool up a few hundred RPM's faster because of the Twin Scroll setup and then a few hundred RPM's faster because of the HTA'd turbo. There are some dyno pulls that show a GT35r vs HTA35r and the HTA has been shown to spool quicker and produce more top-end WHP.

I am a little crazy about waiting and I get home from school in a week and I couldn't wait the month for an HTA35r, so I just ordered the BoostLogic SC61 DBB Kit through ICS, which is on super sale right now. It is a gorgeous looking kit and if you know what a Supra is you know BoostLogic is awesome.

A turbo kit is a big decision, so you have to find what you want. If your going with a GT35r and you have the money there is no reason not to get the Twin Scroll HTA35r. There are no disadvantages to that setup except price. Happy Boosting!

 

One shop questioned the "effieciency" of the HTA
One shop didn't like the "Twin Scroll" setup but didn't get into detail

 

how is the boost logic kit for you ...any numbers ?

 

I've seen a bunch of scenarios where the HTA35r has outperformed the GT35r, but I have only seen one case where the HTA and GT were identical in performance. I do know of one shop that does tell its customers that there isn't a difference between the HTA35r and GT35r and they back to back tested them. I'm a believer in the HTA after seeing so many positive results.

I can not speak for the Twin Scroll setup as I haven't seen any hard facts on it (assuming were talking about ETS), but as with everything Tom and ETS comes out with, the quality looks amazing and I am sure results from the twin scroll setup will be available soon (hopefully).

 

I drop off my car Monday morning the 12th at ICS and should have numbers by the end of the week. I'm hoping for 500whp+ with alky injection. The kit was a great price I don't think I could have gone wrong.

 

There is so much more to choosing a turbo kit than the actual turbo. The choices you have listed won't get you a winning combination. Since this thread will turn into a pissing match quickly that is the only input I have to give.

 

from what i have gathered twin scroll spools up ''hits full boost'' faster then HTA or reg turbos. i have only 1st hand experience with hta 30 and 35r and twin scroll 30 and 35r. right now my stock block/head/ecu/on a flash evo8 with TS 35r hits 26.5 psi at 4500rpm. my 30r hit 26psi at 3750. but anything bigger am im a lost duck

i have yet to see any HTA come close in spoolup or peek boost by a given rpm.

the topend of a TS setup is always a factor for some. people just do not understand how to properly setup the right hotside size to answer there questions and to fix the problems there having. im not a smart man but anyone should be smart enough to know you cant go putting a small *** hotside on a TS setup and expect it to keep climbing to and past 8krpm ''35r like turbos'' you need the big 1.00 to 1.15 side hotsides to make up that top end. but then people cry about spool up. holy crap its TWIN SCROLL. thats the point. i dont know. i voted twin scroll NO HTA.

 

Even if the HTA35R twin-scroll doesnt make more power, dang it looks might fine. Something about twin wastegates makes it look hot!

I have order this kit. Even if it only give me marginal gain, I wont be upset. Some gain is better then no gain, and because I only plan on ever buying one turbo kit for my evo, might as well try and get the best.

Do it right first time.

 

I believe the OP is intending on going with a quality and proven kit from a reputable company (i.e. ETS, AMS or Buschur). It is understood that the Turbo doesn't make the kit, but it is an important aspect when deciding which kit from a company you would like to purchase. I know you alone have a huge range of turbos to choose from along with cast and tubular manifolds, etc...

 

So give me a winning combination in a PM
