Tuner Tuesday: 1996 BMW M3 LS1

Why do I like posting American V8 swaps to German cars? Well, in part it’s because they’re a fantastic performance value. In dollar per horsepower produced, it’s just downright hard to beat a package like the GM “LS” line. Yes, they’re a blunt tool compared to the precision work that typically characterized the stock motors the original car came with – but sometimes, you just need or want a big hammer. The “LS” wasn’t just a a unintelligent lump of iron, though – with aluminum construction, they’re often lighter than the engines that they replace. Two of the favorite chassis to stick these engines in are two of the best regarded, best handling chassis out of the box that enthusiasts love to modify – the Porsche 944 Turbo and the BMW M3:

Hello,

Up for sale is my 1996 Hellrot LS1 M3, purchased in stock form back in September of 2010. Over that winter it received a laundry list of fresh OEM parts, proper maintenance and a complete suspension overhaul with the addition of the AST 4100’s. August 2011 I decided to replace the S52 with an LS1. The LS1 conversion was completed by spring of 2012. That year I was able to track the car @ Mid Ohio, PIT Race and Nelsons Ledges, other than a wheel bearing the car has never had an issues. Over last winter the transmission was refreshed and installed a Monster clutch, a mild cam along with the necessary valve springs, pushrods, timing chain and oil pump. Erik Johnson from Back Street Performance in Medina, OH dyno tuned the car and it put down 374whp & 337wtq. The car is always garaged, only driven a couple days a week during the summer months. The car is extremely reliable, leaks no fluids and gets relatively decent gas mileage. This year I have not found time to enjoy the car to its full potential and believe it’s time to pass this along and let somebody else enjoy it.

There are a couple issues:
1. Paint- I bought the car knowing it was going to need paint as someone keyed both sides of the car. My plan was to add fender flares in order to run 285’s and have the scratches fixed then.
2. Driver’s Seat – Bolster leather is worn out & seat bottom is torn. This wasn’t an issue to me as I was going to install a cage, fixed back seats and safety equipment.

Below you will find a list of modifications & replaced parts. If there is an asterisk next to the item that means the part is brand new and installed this year. Due to my busy schedule please PM me with any questions and I will get back to you.

374 wheel horsepower out of a supercharged M-motor is possible, but it’s going to cost you. This swap is not only powerful, but looks really well executed. Outside of the slightly larger single tailpipe, there are no clues as to the performance that lurks under the hood. To me, that’s perfect – it’s a true sleeper. Sure, the no heat/no air conditioning will eliminate a lot of the country’s interest – but as a car you can drive to the track and spank most race cars with, it’s impressive. The second reason I really like these swap, though, is that they seem to raise the blood pressure of purists. So what if it’s not original? It’s faster, handles better, is likely cheaper to fix and you gained a speed. I bet the fuel economy is even similar loafing in 6th to the original S50. This is one great package, and while it has some slight condition issues and I’d change the wheels pretty quickly, overall it’s dollar per smile ratio far exceeds most M cars in my opinion.

Thanks to our reader Ry for the great spot!

  1. Instead of messing up two good cars, I would buy the Corvette and the M3, and enjoy them both for what they are.
    Maybe the next time I get a Rolex, gonna have them put in a Seiko movement, so that it can keep better time !

  2. I didn’t send this in @Carter, another Ry? Last thing I sent in was the Benz wagon 5-speed! Do I have an imposter sullying my name? Zut alors!

    I’m with @Audimans on this, I respect those machines on their own quite a lot and can’t think of a really compelling reason to do a #frankenswap other than an exhibition of my shade tree mechanic skills (purely hypothetical).

    Also the LS1 that this vehicle has is like 3-4 generations behind in SBC development, and those last coue generations were a huge step up. The only thing going for the LS1 is that you can get one easily at your closest junk yard.

    I think the coolest thing to do would be to stuff an M5 V8 or V10 in there, but still the cost to benefit is really not attractive.

    New Vettes are Uber fascinating, if I had the resources I’d totally do a 1-2 yr lease to check out all the amazing tech. They even have/(had?) a deal where you can participate in your own engine assembly along with the master tech.

  3. The LS conversion is so right in this chassis.
    I like it a lot.
    I think the price is a little rich without AC and other details, but offers are being accepted.

  4. For reasons I can’t explain, the Ford 5.0 in the Volvo wagon has probably always been my favorite #Frankenswap.

  5. When somebody puts cone air filter in engine bay where it’s going to draw in hot air and effectively kill HP and then calls it custom air intake, I seriously doubt the quality of build.
