My Twin Turbo ls2 Chevelle I have been ready and learning from this site for a long time. I have done a few Lsx swaps into various cars and trucks. I just wanted to post up some pics and info on one of my current cars I just completed.
This is my 69 Chevelle. It has a LS2 408 with twin gt-32r. The motor has l-92 heads with an l-76 intake. It has a mild tubo cam and a fast 92mm throttle body. I used Trans Adapt mounts and a Moroso oil pan.
The trans is a full manual th-400 with brake. It has a Continental 3200 converter and a large cooler with a fan.
The rear is a 9" ford with auburn posi, 35 spline MW axles and 3.50 gears. It has double adjustable upper and lower arms and Qa1 adjustable shocks with anti roll bar.
The fuel system is a Stainless steel sumped tank with -10 feed and -8 return. An aeromotive A1000 pump and filter with controller. The fuel rails are fast and a aeromotive boost refrence regulator. I have 79lb/hr RC Component injectors.
The car went to the Dyno last week. On a Dyno jet it made 613/637 on 8psi with pump gas. On 16 psi on leaded 111 it made 822/863. There is room to grow this was only on base tunes and it split my th-350 case in half. Now it has a th-400. Thanks for looking and any questions or coments would be great.

Nice ride. That's one of my favorite cars. I did a frame off on a 69 SS that we originally did as a hotrodded stock car. Then he wanted to go racing. So out came the 396 and in went the 540BBC, 800hp 10 second motor on pump gas. Heres a pic. The owner sold it a few years ago now.

pretty cool-i started out with twin turbos, but ended up with another procharger on the LS motor-i mounted my pump same as you did, except i used a filter in front of the pump, another after
how do you like the controller, i never used one but wondered if it saves the pump(i bought a spare pump cheap)
im guessing your using an a/w intercooler, from the size you might be max'n it out-i know some of the blowthru guys find the a1000 maxed out around 800 hp, i just never hit that mark-do you use a resv. with ice, or a small rad in front for cooling the i/c-i had made a setup in another car with a rad., worked pretty good(still have a spare small rad im gonna sell)
i mounted a procharger 3 core sheetmetal i/c in front, seems to work good, was a little tricky clearing everything, glad the 69 has the openings in the front bumper for air flow, back in 69 GM new it would be getting an i/c, lol
the turbos really seem to make power in the LS motors, maybe one day i will switch
good job

I like the GTO seats. still have plenty of room. I do have a w/a and if you look on the drivers side you can see an aluminum water cell. I also run a front mount. With the A1000 on my turbo mustang it has made close to 900 and didn't run out of pump.
