BILLY COLEMAN - Manta 400 Replica

First step was to strip the shell, bolt it onto my spit, remove the rusted chassis rails and weld in new rails and covers, which were also lengthened beyond normal length to increase shell rigidity.

BILLY COLEMAN

Manta 400 Replica

Ever since I was a small child, my dream car was the Opel Manta 400. 

It really started with the 1983 RAC and Manx rallies, and that well known "Dear God" moment with Ari Vatanen and Terry Harryman and the infamous cattle grid.. 

I just had to build a Rothmans 400 replica, and initially my first Manta was supposed to be it, but that became the Billy Coleman replica, hence this new project car, acquired in 2003 and stored since, was to be the one. Initially I had intended on simply 400 kitting and painting the colour scheme on, leaving the GTE interior factory spec, but delays meant time to rethink, and slowly the boundaries were pushed out, additional 400 features were added, and the workload and cost increased dramatically. 

Chassis modifications to 400 specification, 400 roll cage, floor strengthening plates, rear axle top link tunnels, shock turrets, and front wheel clearance bubbles were among the changes to the standard Manta shell. 

First step was to strip the shell, bolt it onto my spit, remove the rusted chassis rails and weld in new rails and covers, which were also lengthened beyond normal length to increase shell rigidity. 

The boot floor spare wheel well was also removed, ready for a 400 spec battery holder and oil tank, as well as a 400 fuel tank. In the interior, the 400 cage and dash bar were welded in place as tight to the shell as possible, and extended out to the front cross member bolts. 

Once the shell prep was completed, it was sandblasted and wire wheeled to the bare metal, before rust preventative RustBullet primer (marine grade) followed by an epoxy primer. 

Two pack paint in Opel OP452 was applied to the engine bay, boot and underside (after which the underside was coated with Upol Raptor with OP452 tint). The interior was painted in a satin black, and the dash was wrapped with a pattern vinyl similar to that of the original 400, the restoration of a works Ascona 400 Mota Lita steering wheel, and the acquisition of Russell Brooke's Terratrip ARC to complete the dash was a nice finishing touch.

 As it stands currently, my specifications are as follows:

  • Getrag 240 Manta gearbox
  • Safari spec Grp4 radiator
  • 2 turn rally quick rack
  • Rally oil cooler below 400 spec Dzus clipped light pod
