OPEL ASCONA

A 70’s rally legend reborn for the road!

CLIENT NEEDS

Restore my rare 2-door Ascona and reimagine it as a replica of the iconic 400 homologation model only with power courtesy of Vauxhall’s legendary C20XE 16V.

OUR SOLUTION

One of our first ground-up builds, we completed this project in 2011.

A bare-metal bodyshell laid the foundations for a striking homage to the original 400 homologation car.

Power comes from the legendary Vauxhall C20XE, which when equipped with Jenvey individual throttle body fuel injection, a custom stainless exhaust system and MBE engine management, give the car enough “go” to back up the motorsport look!

Seat cloth was custom woven to replicate the rare original material, providing a faithful recreation of the Opel original.

KEY FACTS
  • 200bhp Vauxhall C20XE 16V engine
  • 5-linked Salisbury 4HA axle with LSD
  • Custom woven seat cloth
  • Bilstein dampers
  • Vented front discs and solid rears

Both the Ascona and the Manta 400 have become indelibly linked with Retropower over the course of the last decade and a half or so, a span of time that’s seen us grow to become one of the ‘go to’ places for those seeking to scratch their Group 4 Opel-itch. Curt Pattinson was the very first though, and his XE’d Ascona B 400 replica has become something of a showcase for the kind of work we’re capable of producing here, and all this despite the project itself first taking shape a full fifteen years ago.

Curt’s Ascona project came about thanks to a long standing fixation with Opels of all kinds, a passion shared by most of the Retropower staff. The fact that we’re also huge fans of Russelheim metal helped convince Curt to entrust us with the build, and thus began the very first Retropower, ground-up restoration.

We were aided by Curt’s willingness to get his hands dirty from the very beginning, meaning the shell which arrived at Retropower HQ in 2010 was ready to be put onto the jig, then sent for a media-blasting session. This revealed a degree of rot (it is an Opel from the late ’70s, remember), much of it centred around the inner wing and the bottom of the A-panel. We fabricated the latter from scratch, partly to ensure that the work was done correctly, partly as sourcing OEM replacements is a chore akin to counting hen’s teeth! Fresh steel was also added to the jacking points, floor pans and the Ascona’s infamous ‘swan neck’ chassis rails, both of which were made from scratch.

There’s more involved in turning a ‘bread and butter’ two-door Ascona into a 400 replica, which is why we found ourselves widening the front and rear arches to better accommodate the 9x15in Revolution wheels, and also replacing the roof skin in order to remove the sunroof on Curt’s car. The icing on the cake? The 400 bodykit and coat of Polar White paint of course.

The XE, complete with QED direct-to-head throttle bodies and MBE management, was paired with an Omega gearbox and five-linked Salisbury 4HA axle, a setup not a million miles from the one Opel devised for the ‘real’ 400s. It’s proved more than up to the task in the intervening years.

As we already touched upon, Curt’s Ascona build was effectively genesis as far as ground-up Retropower builds are concerned and we’re proud to say it still looks utterly stunning a full 7 years on from its original completion. Get in touch if you’d like us to build you something similar.
