FYI: The 1991 BMW 318i has been revamped with a supercharged S52 engine. Is the $27,000 price tag warranted for this modded classic?
BMW enthusiasts have long cherished the E30 generation from the ’80s, and its models have become a beloved pillar in the brand’s storied history. Today, we’re examining a 1991 BMW 318i that’s undergone significant upgrades—most notably replacing its original underpowered four-cylinder engine with a supercharged S52 inline six-cylinder. Let’s dive into whether its asking price of $27,000 is justified.
High-Powered Transformation
The BMW E30 platform has always been admired for its driving dynamics and timeless design. The 318i originally came with a 1.8-liter four-cylinder engine, which, while adequate, didn’t deliver the thrilling performance that many enthusiasts crave. Enter the S52 inline six-cylinder, a venerable power plant, originally rated at 240 horsepower from the factory. This particular 318i has taken it a step further by adding a Vortech RMS supercharger, ramping up the power and turning the car into a performance beast.
Professional Overhaul and Modifications
A detailed look at the photos from the online advertisement reveals the S52 engine swap was executed with precision and professionalism. The engine bay appears tight but well-organized, hinting at meticulous craftsmanship. With the chassis logging 189,000 miles and the engine only 80,000 miles before its transplant, the combination aims to offer a blend of nostalgia and enhanced performance.
Significant Additions and Replacements
Supportive mechanical modifications accompany the engine replacement, according to the seller. These include new bearings, bushings, gaskets, and seals. While it’s not confirmed whether this 318i retains its original limited-slip differential (LSD), it’s a critical factor to consider as the S52’s increased power may challenge the longevity of the original 318i’s drivetrain components.
Cosmetic Enhancements
The car’s appearance has also been refreshed with a recent repaint in its factory color. Although some trim pieces appear missing in the photographs, the seller assures potential buyers that these will be installed before the sale. The ESM wheels featured in some images will not be part of the purchase, leaving the factory BBS wheels as standard equipment.
Interior updates are another highlight, with a well-preserved cloth interior. However, it’s important to note that some imperfections remain, such as a cracked dashboard and a worn driver’s seat cushion. The seller includes fabric for seat repairs, which is a thoughtful addition. Other interior updates are a bit of a mixed bag, including an out-of-place silver Kenwood stereo and a funky carbon-fiber steering wheel.
Functional Shortcomings
There are some notable drawbacks to account for. The car’s air conditioning system is non-functional despite featuring the original controls, which may be a deal-breaker for buyers in warmer climates. Additionally, the car boasts a "truck" exhaust and a newer Z3 steering rack. These modifications might appeal to some but detract from the vehicle’s original charm for others.
Smog and Registration Woes
Prospective buyers must consider the vehicle’s smog compliance, especially since it’s listed in California. The car still carries a three-year-old California license plate tag, raising questions about its smog certification and whether it can easily pass current emissions standards.
The $27,000 Question
With an MSRP of $27,000, this 1991 BMW 318i invites robust debate. For some, the extensive modifications and stellar performance enhancements justify the steep asking price. For others, the price might seem too high given the hidden costs of interior fixes and potential smog issues.
Conclusion
Is this supercharged, S52-powered BMW 318i worth the $27,000 asking price? That’s for you to decide. There’s no denying the allure of a classic E30 with modern performance upgrades, but balancing these improvements against the purchase price is crucial. What do you think of this high-octane E30?
