Current revision

Datsun 1200 originally fitted with automatic transmission has a much larger tunnel. It makes it easier to swap in larger transmissions or larger engines.

Contents

Overview

Comparo: Manual transmission cover vs automatic transmission cover
18963.jpgAlbum 18963

Manual Tunnel is very small to fit the small stock transmissions and increase space inside the passenger compartment:
884.jpgAlbum 884 2133.jpgAlbum 2133

The manual body has one piece lower dash panel with no joins whatsoever - the bellhousing part of tunnel is one piece with firewall.
26010.jpgAlbum 26010

By contrast the Auto body has separate dash panel and floor. The transmission cover is spot welded in. The welding seam is clearly noticeable on the firewall at the back of the engine.

Manual tunnel has no seam
7476.jpgAlbum 7476

8197.jpgAlbum 8197 174_57f59d054a0b9.jpgPost 295233

NOTE: Unlike a B110, the B210 has the same floor auto and manual - the stick and slushbox tunnels are the same on a B210.

Swapping Tunnel panels

You can swap the larger automatic tunnel into a manual transmission car. The B210 tunnel is nearly identical to the 1200 automatic tunnel. In turn, the 610 (180B) tunnel is nearly the same as the B210 tunnel. See #Tunnel Swaps below.

Modified Tunnel

Just take a big hammer and bang the tunnel sheet metal ("massage it") to get more clearance.
880.jpgAlbum 880

Or cut part of the tunnel and weld on a bigger section
438.jpgAlbum 438

You can also move the gearbox mounts back to suit various transmissions
5008.jpgAlbum 5008

Maddat Tunnel

Product No TT1200SR Transmission Tunnel. Suit 1200 with SR20 or CA18 Gearbox. Comes with rubber gear stick boot. These can be installed in about half a day.

Note: fitment requires removal of heater box.

For 1200 SR conversions, it will allow the gearbox to be removed while the engine is still in the car. Very simple to install, just sit over existing tunnel, trace with texta. Then cut out inside the line by 10mm, weld the tunnel from inside the cab. From underneath now tap up that 10mm lip (can be made easier if heated up with oxy), run some seam sealer around the joint to finish off.

Custom Tunnels

Others have successfully bolted or welded in tunnels from:

Tunnel Swaps

The standard B110 uses one piece lower dash. The Auto dash is two pieces (lower dash + cover).
26010.jpgAlbum 26010

The rear half of the tunnel is part of the floor
26009.jpgAlbum 26009

In actual practice when swapping, the "tunnel" is cut out of the dash and floor.

Auto Tunnel Swap

Auto tunnel is very large to fit the 71-series Automatic Transmission, but still fits under the heater box.

Auto Tunnel retrofit - tunnel can be cut out, then the new tunnel welded to the floor & firewall:

NOTE: All B210/120Y use the larger size tunnel

However the B210 floor pans differ:

  • from 1200 as to where the transmissions mount points are. You can move the brackets if necessary
  • B210 used eight different tunnels. See Tunnel Comparison.

A10 Tunnel

Several club members have fitted an A10 Stanza tunnel to the 1200.

the satnza tunnel in- looks ok, but i wouldnt recomend it as an easy swap(my first one but piggys 3rd or 4th one). 120y was most stright forward he said, but heaps of room around this one
