Stark automotive – Helping you build your dream Lotus

Welcome to Stark automotive, home of DIY Honda engine swap kits for Rover-engine’d Lotus Elise and Exige.

Update October 2025: we will shortly cease production of our swap kits. The remaining sub-kits and spares will shortly be made available – more information, pricing and available stock will be shown in the table below. For a quotation, please email us with your requirements and delivery address.

Sub-Kit	Description	Price £GBP	Available stock
Engine Mounts (standard black powdercoat finish)	Our mounts were CAD designed by professional engineers and have undergone continual refinement based on feedback from our professional installers and DIY convertors. These optimised parts are designed as ideal mounts without excess weight, each is constructed from mild steel, plated or powder coated black for corrosion resistance (optional colours available). The kit consists of a new nearside engine mount, offside engine mount, front and rear engine torque steady arms (pre-fitted with rubber bushes), front and rear steady arm chassis brackets and all necessary fasteners.	£910	TBC
Exhaust Pic: Stark manifold with standard decat link pipe for S1	Our exhaust kit includes a custom designed, free-flowing 4-2-1 exhaust manifold made in stainless steel and matching link pipe to meet up with the factory back box (or any aftermarket back box which bolt up to the the original system) plus new gaskets and fasteners. A sports cat link pipe is available as an optional upgrade. Our exhaust has been extensively dyno-tested and proven to make good power (we have seen 236bhp without a cat, 225bhp with a cat, when coupled with a good intake and a professional remap).	£1040 (standard decat option, sports cat optional)	TBC
Gear Linkage	Our CAD designed gear linkage kit gives an incredibly positive and direct gear change using self lubricating bushes. The gear linkage is also adjustable to suit personal preferences. The original gear change cables are replaced with high quality items, custom made specifically for our application. These follow the optimum route to the new linkage providing a smooth feel to gear changes. The kit consists of a pair of heavy duty cables, gear linkage plate assembly with rocker arms & bushes, spacers, swivel joints and all necessary fasteners.	£660	TBC
Driveshafts	Two complete driveshafts which feature incredibly strong 300M steel axle bars, custom boots, grease and all-new inner and outer CV joints. The S1 version includes a machined toothed ring for the dash speed sensor.	£880 + £40 upgraded grease	TBC
Sump Baffle	The sump baffles are custom designed for the K20 engine (with aluminium sump) and are a bolt-in fitment for security. Sump baffles are an essential part of the conversion to prevent engine oil starvation under hard cornering and track use.	£210	TBC
Coolant & Fuel	A full, high quality, silicone coolant hose kit (black as standard, other colours available), including a custom silicone reducing hose assembly, jubilee clips, water/oil cooler hose, hose elbows and metal hose joiners. Fuel parts includes high-pressure fuel injection hose, fuel hose fittings, brass T piece, Sytec motorsport fuel filter and a Webcon fuel pressure regulator.	£320	TBC
Completion	The Completion sub-kit includes a number of custom-made items plus all the “odds and ends” required to complete your conversion: large sheet of heat shield material, edging tape, rivets and washers, custom machined inlet manifold blanking plug and temperature sensor adaptor, non-aircon ancillary drive belt, custom clutch hose adaptor assembly, head outlet water fitting with sealing washer, cam cover breather filter, heavy-duty electrical junction box, strip of reinforced cable edging, roll of cloth loom tape, set of undertray spacers and a length of induction hose and clip.	£270	TBC
Build Manual & Wiring Notes	A 50+ page colour pdf manual providing concise step by step instructions on every aspect of the conversion. This covers useful tips in advance of your installation, advice on sourcing donor packages, through to recommended insurers, maintenance and servicing of your replacement engine. Plus, a set of detailed instructions and ECU pin-out tables covering the electrical/wiring side of the conversion. These include instructions on splicing the Honda engine and starter looms to the Lotus looms, wiring of the Lambda sensor, how to retain the Lotus MFRU and all the connections necessary to get your Honda engine running and Stack dash working.	£40	TBC
