3.1L, built for boost. This BimmerHeads M20 Race Stroker Engine is machined in-house and hand-assembled on California’s Central Coast.

A forged rotating assembly is at its core, with a Nuke adjustable cam gear, PPF billet tensioner, Gates Racing timing belt, and our BimmerHeads M20 Fastener Kit among the highlights in this shot.

Next stop is our test stand for camshaft break-in, leak checks, and quality control. Once everything checks out, it’s off to the East Coast. See what goes into our M20 engines at BimmerHeads.com 🏁

CP-Carrillo forged pistons for BMW M10, M20, and M30 engines. After years of building these engines and testing forged pistons from all major manufacturers, CPCarrillo Pistons & Rods is our clear choice.

Options for naturally aspirated and boosted applications, with custom configurations available. Forged from 2618-T1 aluminum and laser-engraved with our BimmerHeads logo. These are the same pistons we include in our M20 Stroker Kit and M20 Race Stroker Engine.

M20 perfection. From the raw block to the final valve cover nut, another Classic BMW engine is officially wrapped up. 🏁

The M20 inline-six is one of the absolute greatest power plants BMW ever produced. Bringing these engines back to life with absolute precision is what we do best—keeping the legend alive for decades to come.

This turbocharged, BimmerHeads-built M20 stroker engine looks absolutely wild! Owned by our friend Frank, this is one of the most elaborate BimmerHeads-powered M20 engine bays we’ve ever seen. We love it!

If you are ready to make serious M20 power, don’t guess the recipe. Trust the experts who back it up.

Thank you Frank LeoGrande of LeoGrande Racing LLC for always being such a great customer and friend. Shoutout to STIM TECHNOLOGIES for the incredible parts on this build as well!

We love seeing customer projects come together—take a look at Mike’s fresh turbocharged M20 stroker engine. This setup utilizes a complete top-and-bottom-end configuration right out of our catalog, including our 885 cylinder head, a stroker kit, upgraded hardware, and gaskets. Engineered for boost and built to last. 🏁

Huge thanks to Mike for sharing his progress. Head over to BimmerHeads.com to check out the M20 platform catalog.

We thought we’d share one more photo set from the recent E30 M3 overhaul completed at the shop.

The owner made sure to reach out and let us know his E30 M3 is performing far above his expectations. We love when our customers are happy with their investment! Let’s make you happy too. Shoot us an email for pricing and availability inquiries. 🏁

BMW S14 cylinder head rebuild recently completed by BimmerHeads. We’ve neglected to share a lot of these S14 builds with you all in the past so we’re changing that!

This head was a good condition low mile example with no surprises. We retained the original OE BMW valves but went with new supertechperformance valve springs. We also used Supertech valve guides. The camshafts stayed OE as well but they were reconditioned while removed.

While we’re guilty of giving the M20 a lot of attention, we’re capable and willing to take on your S14 and S38 projects too. It’s a pleasure for us to work on these special engines and cylinder heads.
