Brian Crower Nissan TB48 Stroker Kit (BC0255LW)

When you’re building a TB48, you’re usually chasing big power, and eventually, the stock internals just aren't going to cut it. The Brian Crower BC0255LW Stroker Kit is the real deal for anyone tired of questioning their engine’s durability. This isn't just a collection of parts; it’s a full rotating assembly designed to push your TB48 displacement up to 5.20L.We’ve seen plenty of these builds at the shop. The beauty of this specific kit is how it balances that extra displacement with high-RPM reliability. You get a setup that pulls hard from the bottom but doesn't feel like it’s going to shake apart when you hit the top of the rev range.

Why the BC0255LW is the Shop Choice

  • 110mm Stroke: This is where the magic happens. That extra stroke bumps your displacement up to 5.20L, giving you massive torque gains that you’ll actually feel on the street or the dunes.
  • 4340 Billet Crank: This isn't a heavy, clumsy crank. It’s a 4340 forged steel billet unit that has been gun-drilled and cross-drilled for better oiling. It’s lighter than the factory piece, meaning the engine revs faster and hits boost that much sooner.
  • ProHD I-Beam Rods: These rods are the muscle of the kit. They come fitted with 7/16" ARP hardware because they are meant to handle the kind of boost pressure that would snap a stock rod in half.
  • Matched Precision: Because the crank, rods, and pistons are engineered to work as a set, your engine builder is going to have a much easier time getting everything balanced properly. It takes the guesswork out of the assembly.

Features & Benefits

  • Forged Strength: Everything in this box is forged 4340 steel, designed to survive the extreme cylinder pressures you see in high-boost applications.
  • Windage Control: The crankshaft counterweights are profiled to reduce windage in the crankcase, helping the engine stay stable and efficient at high RPM.
  • Custom Piston Options: You get custom forged pistons designed for strength and ring seal, which is critical if you’re planning on running high boost without burning oil.
  • Built to Rev: Even though this is a stroker kit, BC’s design philosophy keeps rotational mass low, so you don't lose that snap-your-neck throttle response.

Vehicle Fitment

This kit is engineered for the Nissan TB48E / TB48DE engine:
  • 2000–2024 Nissan Patrol (GU/Y61)

  • Part Number: BC0255LW

Frequently Asked Questions

Is this a "drop-in" kit?
Definitely not. This is for a full engine build. You’re going to need a professional machinist for the bore and hone, and a skilled builder to handle the assembly and clearance checks. Don't try to build this on a garage floor without the right tools.
Do I need a new tune?
100%. You’re changing the displacement and the compression profile of the engine—if you try to run the stock ECU or an old tune, you’ll likely blow the engine in a few minutes. You need a pro tuner who knows TB48s to build you a fresh map.
Are bearings in the box?
No, you’ll need to order your ACL Race Series bearings separately. Make sure you talk to your builder about the clearances they prefer before you order those.
