Default What turbo’s for Ls1

Hi I’m new here thanks for the add admin,
I’m building a budget twin turbo Ls1 combo for my
race car, it’s currently running a t56 manual gearbox
4.11 gears, 9 inch diff, mini tubbed,
vh commodore, I want to use the Chinese turbo’s
till I can afford to upgrade ,
my engine is stock but I will be putting a cam
for this application, will also be running reputable external waist gates, really would like to make as much as power as possible with my stock engine,,
hoping to run a 9 down the 1/4 mile,, any suggestions on what turbo’s to purchase off eBay,,? Item number would be appreciated. Thank you for reading

I have twin 61mm’s from ON3. My last full pass was a 10.3 at 130. The next pass I broke the drive shaft at about the 450-500 foot mark and I was almost 3 tenths quicker at 330 Mark leaving at 8 pounds of boost so I feeel would of been in the 9s on that pass, car weighs 3380 with me and 15 gallons of fuel

2006 Stock bottom end LQ4 with the factory 317 heads, with a BTR stage 2 twin turbo cam and springs kit, 80 lbs semens deka injectors in a stock truck intake. On the dyno it mad 540 to the tire being conservative because I had a boost creep issue, I got the boost creep fixed and it holds ten pounds all day long with no issues

Cool. I got the 61s so it would spoil quick, I hit my 10lbs before I hit 2500 rpm. My converter is tight I can only foot brake it to about 2400 but I have a trans break in the car so I can stage it higher

The 72 I got have the same exhaust wheels at the On3 61's so hoping they'll light off decently on the brake
