Anyone running a 5.3 and a s400sx3 (83mm 1.10 T4) in a STREET car?

What an Odd question... Why would it matter? Anywho... I am. Street legal anyway...

Haha! Hey man. Im sorta familiar with your combo. Endless reading.

What converter? How does it spool? Maybe I need to read up on your car again...

Depends on alot of things. I ran a low compression setup (8.6:1) and a cam that was lazy in the low rpm's. My converter was a custom PTC 9.5". Stalled around 3500. Prob 3800 on the T-brake.

I may not be the best to compare spool times with. At the track I'd hit 24lbs around 4800.

Anything above 12-13lbs on the street was pretty useless, even with 29" slicks.

IMO it's a great turbo for quick spool 700-800whp goals on a 5.3.

Any opinions on the 75mm version? I'm thinking of building a Sierra or Silverado with one, strictly street. I may take it to the track once just to see what it does.

Are you talking 75mm compressor or exhaust wheels? This is the 75mm compressor version. I believe it uses an 83/74 exh. wheel.

Cool! Thanks! Just the answer I was looking for!

Im slowly buying crap for the car and turbo will be the next thing on the list.

Thanks again!

The 75mm compressor version. I believe the hot side was 1.10 AR.

I was also thinking 2" up pipes. Looking for 550-600 rwhp.

Thanks black89z51. I asked this question over on the Buller and got my head ripped clean off. Lol
