I’m exploring a long-term project idea and would appreciate serious input from people experienced with engine swaps or fabrication work.

The base car is a Hyundai Creta 1.4 TGDi (FWD, DCT). In other markets, this same chassis comes with a 2.0L NA petrol, so there’s already some headroom in the engine bay. I’m considering the possibility of fitting a V6, ideally the 3.3L Twin Turbo from the Kia Stinger or Genesis G70.

Before I go down this rabbit hole, I want to know whether this is physically and mechanically feasible — as in: • Would the V6 fit in the Creta’s engine bay without total reconstruction of the subframe and firewall? • Could custom mounts, driveshafts, and transmission adaptation make it workable, or is the geometry completely incompatible? • Since the 3.3TT is part of the Hyundai–Kia group, would ECU integration and sensor compatibility be less of a nightmare than an LS or JZ swap?

This is a cross-over project build, i ofc want it to be daily driver. I’m not concerned about cost or time — just engineering feasibility and which UK shops or fabricators might be capable of tackling something on this level. Im interested in seeing how this body performs with a v6.

If it helps, I’m fine running it on a standalone ECU and fabricating custom engine mounts or exhaust routing. What I need to know is: is there enough physical and structural space to make a V6 swap possible in this chassis?

And most importantly — which UK tuning or fabrication firms would realistically say yes to a build like this and execute it reliably without cutting corners?

Any insight from people who’ve done Hyundai/Kia platform swaps or custom fab work would be much appreciated.
