LS1 in 1st Gen questions...

[powermetal]

Steve68-

My subframe is the stock subframe that came with the car, just modified for the LS1 and rack and pinion steering. I went with the BRP steering kit that uses a stock 4th-gen F-body rack. The other side of the subframe is modified to make room for the steering shaft to connect to the rack. The shaft runs through that channel that was created. I two ears in the rear are the motor mounts. My car uses the stock Vette perches and pads. I really like that setup. The pocket that was created to make room for the A/C compressor is pretty big. Once the hole was cut, the subframe was welded up on the inside everywhere that could be reached, and the hole was boxed in. I planned on using the stock GM A/C compressor, but it turns out that a Sanden unit actually works better with my A/C system so that's what I have now, and it is smaller than the stock compressor.



I also went with a Rock Valley tank. I can't think of a fuel-injected car made today that has an external pump, so there must be something to it. I have a Vette fuel filter/pressure regulator, so I have one hard line run to the motor. The final two feet or so of the line is the stock braided piece.

Since my motor sits so low in the subframe and my car is also lowered, I was concerned about long tube headers hanging down too low. My car is a street car and I want to be able to drive over speed bumps etc without dragging. I chose Mac mid-length headers and am very pleased with them. I have a stock '02 LS1 except for the headers, and it made 337 rear-wheel horsepower and 347 lb/ft of torque.

Steve,
As soon as you mentioned R&P, I knew what the ears were for, do you have any pics with engine in place, and which model sanden compresser, I too have factory air, I was just looking at the space you created, the driver side must be for the headers,

I'm going to have to go with the Vette reg deal, one line and clean,

I like headers but stock manifolds are supposed to work well' I think LS6 it's on LS1 tech site, Thanks for a ton of info, Steve

you better read up on those headers. i think they only fit a rack and pinion conversion, but i may be wrong. I bought a new set of pace setter long tubes and modified the front two drivers side tubes. they fit with my factory power steering and only cost me about $300

when you order those stainless headers they offer them with or without the BRP mod just FYI
