US Tuner Tears Down The Supra's B58 Engine To Kick Off 1000bhp Project

This hugely insightful video from PapadakisRacing shows what's going on inside the Toyota Supra's BMW B58 engine
US Tuner Tears Down The Supra's B58 Engine To Kick Off 1000bhp Project

It was inevitable that we’d see a fair few 2JZ-swapped A90 Toyota Supras. The first few - including one from HKS - are already here, and it probably won’t be long before 2J’d GR Supras with four-figure power outputs emerge.

That’s all well and good, but what about the B58 BMW inline-six the A90 leaves the factory with? Munich’s modern turbocharged straight-sixes have gained a reputation for being highly tunable, and we’ve already seen Litchfield raise the 3.0-litre twin-scroll turbocharged unit to 420bhp with a simple ECU tweak. Over in the US, meanwhile, Papadakis Racing is hoping to take things much further.

The Californian firm - which you might remember for Frederic Asbo’s 1000bhp drift Corolla, among other mad projects - intends to push the engine to 1000bhp.

Company owner Stephan Papadakis admits that “this engine is all new to me and I honestly don’t know how I’m going to get there,” although that seems to be a driving force behind the project. “It’s exciting: I live for the challenge of exploring the unknown and pushing toward a goal,” he said.

The first step is a complete teardown of the B58 engine, to give the team an idea of what they’re working with, and the direction the project might take. The process is detailed in this informative video, where we’re given a look at the B58’s interesting features such as an internal exhaust manifold and its variable valve timing system.

We’ll be watching this one with interest…



I think the powertrain warranty will be canceled

I hope this engine can have the same level of tunability as the 2JZ in the future

These beemers have proved themselves in the past. Take the 335i for example. One simple tune and a couple bolt ons can get you 500+hp.

I think it has more, it’s better than the JZ on paper

to be fair i live in the US and never even heard of this guy or his firm, chances are the brits at CT barely know of him either so we wouldn’t know if he’s some big tuner or what

That Engine looks very promising. 1000HP are not going to be a problem. I like what BMW’s Engineers did, not neccessarily the thing with the timing chain at the back but I guess thats not a Problem they’re not VW after all so I guess you won’t need to change it every 5 miles.

The thing is, the normal 2JZ would not have had this amount off 1000+ hp builds, if it weren‘t for the massive amount of tuning companies providing development and parts. Once this starts with the B58 it will be no different. The insane, 2000+hp drag cars for example, do not use any stock parts anyways. They have billet blocks with minimal to no cooling structures and share nothing but the basic construction with the original engine.
