This Lancia Delta Evo1 is the subject of an 112 page modification thread on alive.se by it’s owner, forum member “Pentell”. The project started out innocently enough as a build thread venture to share a few track mods on-line with his internet forum friends. It semi-quickly spiraled into an all-out tube frame revamp which included the install of a Supra Turbo J2Z engine with JZA80 rear end, transmission and axles. Anybody who knows the import tuning scene knows that Supra Turbos are capable of making huge amounts of power, and this build took full advantage of every modification that it could to make it able to produce approximately 1,000 horsepower while remaining reliable enough to race on road courses. In other terms that translates to being able to last more than a quarter mile spurt at a time. That fact alone is impressive enough on it’s own merits before we even jump into the whole home garage, custom fabrication build of it’s tube frame chassis…
Peter Pentell is the name of the madman genius/owner of this epic build who had owned the car for 10 years before starting the complete revamp. After modifying the Lancia’s motor over the course of his ownership for track days and never being satisfied, his obsession to find more power, traction and durability were finally answered in the form of the Italian to Japanese soul transplant.
We are in complete awe of his abilities in creating the tube frame chassis by himself.
The control arms have settings installed in them to allow the option to run 650mm or 680mm tire heights, or can be used to adjust roll center, bump steer and front and rear camber gain.
Three air jacks were installed which came from a Porsche 911 Cup car.
To get weight distribution ideal he set the engine as far back as his race class’s regulations would allow, which made it necessary to cut out the B pillar and move it back 150 mm to make ingress/egress possible.
The engine hardly fit between the bottom of the chassis frame and the windshield.
Normally we aren’t huge fans of cross-pollination between powertrains and chassis from different manufacturers and countries of origin, but somehow the last “Lot-udi” and this one have apparently moved us enough to feature both of them here, one right after another.
Perhaps we have been transformed by these two divine interventions. If that is the case, then by all means we have seen the light, Hallelujah, we are saved!
