Section 3b:
Slot frame rail lip (3071 FMII and FMIIR kits only)
If you don’t know what a 3071 or FMIIR is, this doesn’t apply to you
The orientation of the compressor on the turbocharger makes it necessary to slot the frame rail lip on
the left side of the car. This needs to be a deeper slot than what’s described on the previous page.
Refer to the picture on the previous page to get a general idea of what the slot will look like and to
clarify any dimensions specified. The turbos we use on the FMIIR are pretty big, so you’ll need to cut
a fairly large slot. For this reason, we include a weld-in plate (22-62000C). Please be sure to match
our dimensions as closely as possible, as this will make our plate fit best. Be sure that the exhaust
ports are plugged securely, we want to keep the metal shavings / dust created out of them.
1. First, you’ll want to scribe out your dimensions. From where the vertical face (that connects to
the shock tower) would intersect the edge of the frame rail, measure 3/8” towards the firewall and
make a mark (this is the 1” dimension in the picture on the previous page). Now measure another 4-1/4” from that mark (4-5/8” from the vertical face) and make another one (this is the 3.25”
dimension in the previous picture). Scribe another line that’s parallel to the edge of the frame rail
and 1-1/4” closer to the left shock tower. Make two marks on that line, one that’s 1” from the original vertical face (same as the picture on the previous page) and one that’s 3” from that mark (4”
from the vertical face, same as 3.25” dimension in the previous picture). Now draw a diagonal line
that runs from the marks you just made (1” and 4” from the vertical face) to the original marks (3/8”
and 4-5/8” from the vertical face). That’s the template for the top cut. Now run 1” down (vertically)
the vertical face on the frame rail (which runs fore and aft) and make marks that line up with the 1”
and 4” marks made in the second step. Connect those two marks, then trace a line diagonally up
to the 3/8” and 4-5/8” marks.
2. Cut along the lines you just scribed - a cut-off wheel should work well. Try to make all of the cuts
as straight as possible, as you’ll be welding our plate where you made the cuts. Look at the shape
of the plate and make sure that the hole you’ve cut matches it.
3. Weld the plate in (your battery is disconnected, right?), then paint it to protect it from rust (both the
plate and the exposed edges in the car will rust otherwise). You can try to get it close with off-theshelf paint, or some automotive shops (such as NAPA) will mix a spray can of paint to your specific color.
