Hey guys, looking at doing a twin turbo setup in my car, wanting to hit 800-1000 rwhp on pump/race mix with meth injection.

I plan on building a forged 408, or maybe keeping my 376 and forging it... What's your guys opinion?

I'm trying to figure out a good turbo tho. I'm looking at Garrett gtx3071r or gtx3076r, yes they're pricey, but I'll be doing this project over a couple years so I'm not sticking to a firm budget.

The car will be a weekend warrior, not an all out dragster so street ability is what's important to me.

Any suggestions or comments are welcome.

Thanks in advance

60mm S300 is a poor mans gt3582. I like mine on my LQ4.

I went with a pair of 61mm from a non-sponser. Great specs and good for 1400 with 60% efficiency and 1000 with 70+ efficiency

I would do HTA3582R's if your not concerned about the price. GT30s are too small for a 408, let alone a 376.

I was worried the 3582 would be laggy, more reading looks like the 3582 .8 ar spools pretty quick on a large motor.

Anybody have dimensions of the unit so I can get an idea of where things will fit?

And good intercooler? Looking for 2 inlets - 2 outlets? I'm a metal fabricator, so I might have to make my own.

ebay 35R's

Htas are cheaper than the GTX, but the hta seems to be raved about.

The HTA Wheel that Rob came up with is a master piece, takes a little longer to spool, but makes more power.

Using Garret's boost advisor, the GTX3076s look closer to what I want as far as where they spool. The 3582 is really close to the surge line at 3800 rpm, which is about where I want to start boosting. I want quick spool over high hp

I choose turbonetics 6465s. 800-1000whp should net be a problem. Auto or T56 ?

How are they performing ?

The Precision 6262's or 6266's do seem popular.

I have not get got the car running yet. Waiting on a couple parts. Hinson motorsports sucks !!!
The precision turbos are nice but they almost twice the price. I went with a bigger wheel and a smaller A/R.
