Performance parts package 1.8 NB SG195

This package represents our ultimate stage in naturally aspirated engine tuning. With 195 HP from a fully rebuilt 1.8L engine combined with an individual throttle body (ITB) setup, this is the top of the NA food chain – uncompromising, reliable, and motorsport-proven.

All products, including this performance package, are developed by SPS Motorsport on the racetrack, adapted for street use, and continuously refined. We place the highest value on the quality, function, and OEM-like appearance of every component we install.

Power Upgrade to 195 HP – Components Installed

• Fully rebuilt 1.8 NB naturally aspirated engine (Stage 2)
• Jenvey T45 individual throttle body kit
• SPS header kit incl. sports catalytic converter
• Programmable standalone ECU incl. wideband lambda sensor
• Fully reworked cylinder head with new seals, lapped valves, upgraded camshafts & adjustable cam gears
• SPS Motorsport oil cooler kit
• Half-size aluminum radiator
• New water pump, timing belt, and spark plugs
• Fresh oil change with Motalin 10W-60 HP Racing incl. oil filter

This setup delivers razor-sharp throttle response, high-revving character, and maximum durability – ideal for spirited street driving and track use.

Note: Full power is only achieved when paired with an exhaust system featuring a minimum pipe diameter of 55 mm. We recommend our Group A exhaust system, which can be added as an accessory during checkout. Without it, the 195 HP target will not be reached.
