Hi this has probably ask numerous times? But is 20g turbo on 07 sti with forge pistons and supporting mods pretty reliable? Or just stick to the stock turbo? It's because it's my daily driver. It eats up about 25000 miles a year

 

Wow, 25,000 a year. How hard do you drive your car? The 20g will work just fine and be reliable, it's all in the tune.

 

20g will be fine, i ran a 18g on my 02 wrx

 

I rarely push my car I try to baby it. Hahah but I'm asking cuz it's nice to have the power. And use it when it's needed.

 

I would go with the Blouch 1.5xtr with 10cm. That turbo is nasty, someone installed one on 2011 STi and it out spooled the 20g buy a lot. Check that 1.5xtr out, if you want some more HP I would check the 2.5xtr out! Both great turbos, ATP makes a nice ATP3071 that works great.

 

Get in touch with an actual tuner and see what they can do for you.
My opinion is that it would be fine for your car if tuned correctly and you drove properly as well as maintained the car properly.
Seems pretty self explanatory but I will leave that to the professionals to decide.

 

Ok I'll look into those. Btw are the turbos you mention good with the stock top mountv? I'm trying to Stick with stock top mount. Yah I'm going to have a talk with mike from gst and ask for his recommendations.
