RWD SR20 Civic Part 4 – Its starting to come together

We have been flat out over the past week with plenty of progress, our aim was to try and keep this car rolling as long as possible. Impossible Fabrications have lots of different projects on at the moment and having this car take up a hoist for too long simply isn`t an option. So we set ourselves 2 goals, Get the motor sitting in the cradle cut the tunnel for the gearbox.

The first step to this was to remove all the hard brake lines and fuel lines that are clipped into the firewall. These lines can be bent but not forced, We want to retain as many factory parts as possible, this includes hard brake and clutch lines, factory booster and clutch as well as the headlight loom and factory fuse box.

Firewall

Once these lines were off it was time to clean it up and strip the other side (inside the car) because Honda didn’t want anyone cutting a tunnel in their little Civics, they made sure to run the body loom and the only other wires that we are keeping right in the middle of where we need to cut, This wasn’t a big issue, just a time consuming one.

Now we are all ready to Go, Daniel (Grub to his mates) got to work with his magic pen and removed enough room for the gearbox without taking to much strength out of the floor of the car (key to having a tight car)

Tunnel

Here is the weight reduction mod we completed on our firewall, it is just a guide to make sure the gearbox will even fit in this car (6 speed) we will clean it up once we know where it will be sitting.

We wanted to retain as much of the firewall as possible, but the most important factor was making sure the motor sat in the cradle in the factory position, a common mistake people make when doing something like this is moving the factory mounting position forward to fit the motor, this changes the weight of the front end and can drastically change the way the car handles and feels. (blue tubing is simply there it hold the shape before we secure everything in place)

gearbox tunnel

Here we go, the moment of truth, we removed the shifter but left the gearbox attached as it was easier to check the motor and box at the same time, our aim with this was to keep as much of the motor together as possible, the more we took off the more we had to bolt back on once its in.

We needed to make some small adjustments to the floor to get the box in as it was longer than we thought, this is going to move the shifter location back about 6cm behind factory but i think i can live with that.

Almost in

The hardest part of the front end was to make sure we had it centred and level, Luckily when Grub was putting the front end in he took his time, the box is DEAD centre and fits perfectly into the body.

As you can see once we made some minor adjustments to the tunnel for the gearbox and trimmed some tabs off the firewall the motor sat perfectly. So perfectly in fact that we can still use the factory engine fan, radiator and airbox, The Dump pipe lines up with the space provided, the factory loom enters the firewall in the same (factory) hole.

There is even room for a front mount cooler inside the rad support which means it will not be seen from the front of the car. Although the steering shaft doesn’t line up we are sure Daniel will fabricate a knuckle or an adjustment so that we will have no dramas.

The Civic stock rear end is still in the car so the front is sitting low (1oomm) off the ground, This should change once we lower the back onto its new rear end.

Using the factory cradle means we have HEAPS of after-market parts available, sumps, suspension arms, knuckles, bushes… the list goes on, i think its time to go shopping
