Here's Tech-53 1.4TSI Swap Mount Kit for the VW MK1. The engineered solution for the 1.4 TSI swap. Precision-designed and built without compromise.
This isn't another adapter kit. Every component was 3D-scanned, FEA-tested, and refined through development to deliver the strength, geometry, and functionality this swap demands.
Fabricated from 100,000 PSI steel with machined accuracy that reflects a decade of learning what works—and what doesn't, with a fully FEA-validated design. All parts were CAD-modeled from 3D-scanned engine and chassis data to ensure maximum clearance, precision positioning and optimal oil pan clearance. Entirely TIG welded in house.
We retain factory MK1 side mount bushings in their correct orientation—no reversal required like earlier 1.8 swaps. FEA confirms optimal torque management across all three mounting points.
Mounting System Highlights
-
Passenger Side Mount
Retains four OEM anchor points with integrated 3D boss provision on the cylinder head. Alternator anchors directly for OEM-grade alignment.
-
Transmission Side Mount
Our 7th-generation 02A/02J design, compatible with 1.4 OEM 0A4 transmissions or 02J units with VSS output.
(Note: 02A transmissions lack the lower threaded provision for dogbone mounting.)
