ATP GTX3576 OEM to Rotated Later question

4bang4now · 01-03-2021, 06:24 PM

So my factory turbo is done for. I have a closed deck build head engine I am trying to break in. Eventually want to go rotated in the next few months but I need to get the car on the road.

As a work around I was thinking about going with the GTX3576R or 3582R from ATP. These are a bit different and have the EWG located on the hot side. It's this as an option or internally gated.

Since these are true Garret CHRA I would think I could get the vband hot side when I decided to pull the trigger on the ETS rotated kit.

What are you thoughts? If you were to go 76 vs. 82 which way would you go? This car is mainly for highway pulls and drag it is not used daily.

Current fuel AEM 340 on 1050x. only running 93 until I get the tune and big injectors installed. Then I have radium surge tank with a 450/340, and my current 340 feeing it.

Swapping the turbine housing would be fine. It's a pretty common process to keep a turbo and swap setups.

If not a daily 3582. There will be lag when street driving like a 'normal' person, but it will make way more power than the 3576.

For daily 3576 is the cat's meow for big turbo that retains decent streetability. My personal favorite street turbo.

I would use some high-temp copper anti-seize on the bolts connecting the turbine housing to the CHRA. That should make sure the bolts aren't seized when you go to swap housings.
