I have a HTA35r on my 2.0 4g63 with cams and computer i dont have internals as yet but im working on that and i dont plan on stroking my engine either. I'm thinking about upgrading to a twin scroll hta35 with the same 2.0 motor. Would i get alot more power from this new setup as compared with the hta35r or are the twin scroll turbos only good to run on cars with stroker kits?

you wont really get 'more power' w/ TS setups...its even debatable as to whether it hinders top end performance or not.

what you WILL notice w/ TS setups are a 2-400rpm spool up improvement as well as better 'under the curve' powerband over the single scroll setups.

understand that if you have a hta35 on a tubular manifold, you cannot just buy a twin scroll housing and slap it on and expect it to work...you need the twinscroll manifold as well...

in that case, you MAY be better off building up your motor and stroking it if overall powerband performance increase is your goal...you will be able to run it more aggressively, and get similar/same results out of it as you would just TS'ing it..

hope this helps some.

Until I see proven top end power with TS setup on 2L..............yeah.

Let's put it this way ... if I had the money, I'd swap out my existing kit (AMS 50 trim) with a Full-Race TS HTA35R. Realistically, I'll probably end up upping to an HTA35r on my existing kit, though. IMNSHO the Full Race twin-scroll kit is the only TS kit I'd consider (I'm sure I'll get flamed for that, LOL). It is also the only kit I would consider in favor of the AMS kit. Twin scroll will not give you more topend, it will help to spool the turbo earlier. On a stock 2.0L that's going to be fairly important, as you don't have a lot of RPM to play with. If you're going with a built 2.0L, then it becomes less critical, as a powerband from 4500-9000 RPM is just as good (actually slightly better) as 3500 - 8000 RPM.

See Most Wanted, 9sec9, or search for the Anibal Evo. All trapped 140mph+ on a TS setup.

i understand the need for a twin scroll manifold..the plan is to replace my current kit with a complete hta35 twin scroll setup altogether with a complete built 2.0 motor.
i only plan on doing work to my head i dont really want to trouble my block besides make it stronger (pistons, rods etc.) i dont want to go the stroker route.

Hey I'm new to evo's why you 2.0 and not bigger?

NitrousOxide

2.0s rev higher(less stress on connecting rods), while the bigger the displacement the less the RPM.

Big turbos rev up late and therefore need a high RPM powerband to extract thier power. If you install a big stroker (2.3 or 2.4 for example), you'll be limiting the output of the turbo as thier will be a conflict between the max RPM of the stroker and the neccessary high-rpm powerband of the turbo.(stroker has ~7000 rpm max; big turbos rev to 8500 rpm or more; therefore, you lost 1500+ rpm due to stroking the engine.

If power is the aim, 2.0s are best, for drivability, bigger engine work better.

Hope that helps

go with the twin scroll and a sp engineering quick spool valve ftw.

I have a built 2.0 and am going with 6262 T3 forward facing setup....THE BEST STREET TURBO

Ok that makes sense. Hey I have full exhaust,fuel pump,750 injectors,piping, intercooler,20g turbo,boost controller,fuel rails,280 cams,and apexy fuel management. Now I have $4000 what step should I take next. Thanks for your time and help

HTA with the twin scrool housing and fullrace t4 twin scroll manifold is the only way to go

When it comes time to go big turbo, i will go with a twinscroll setup. I hate lag.

I plan on going with this setup as well and just to think that the hta3586r and a ts manifold together minimize the big lag that the standard 35r and a regular tubular mani have.

Full-race just lowered the price on the t3 ts manifold to $900 from $1,600.
