For the engine
For the B58b30
Built BMW B58 Engine for 1000Hp
  • Forged Pistons - Custom Compression
  • Forged H-Beam Rods
  • Stage 3 CNC Port & Polished Cylinder Head
  • AMSE Ductile Iron Sleeves
  • AMSE Coated Rod & Main Bearings
For b58b30C
Same rod, Coated Rod & Main Bearings than B58
New piston and Cylinder Head
Block?

Do you now were arsenalmotorsports find B58 Forged H-Beam Rods?

Stock sleeves should be good for whatever you throw at it. Coated OEM bearings should also be good unless the price difference is negligible to AMSE's. IMO Forged pistons and rods should be more than enough for 1000HP. The rest is just complementary.

A black A90 Supra with the following mods would be the ideal for me...
- Top Secret wide body kit with extending trunk spoiler to give the car the proper proportions
- VOLK TE37 Ultras 19"
- Flat carbon roof to eliminate the factory one
- Aragosta Coilover suspension kit F/R
- ENDLESS 6-piston / 4-piston w/ CC-X pads F/R
- TRUST Front mount intercooler kit
- Boost-up ECU tuning
- Downpipe / Titanium exhaust

You want replace the air/water intercooler by a air/air intercooler? :popcorn:
Was it confirmed that it's going to be air/water intercooled? I thought only the exhaust manifold was water cooled...? I know this is off-topic but I've been thinking about the reason behind why they did this but it just doesn't seem logical to me. Shouldn't the exhaust gas be hot to increase air velocity going into the turbine? :what:

Yes. The intake manifold features an integrated air-to-water intercooler. Not my first choice. However, the relatively-high (yet stable) temperature of the intake-charge makes for easier OEM tuning.

I'm not sure where you got the idea that the exhaust manifold was water-cooled. Maybe it's because all 6 cylinders expend their exhaust through only 2 ports in the head. Not a fan of this design either. Anyway, the center section of the turbo is definitely water-cooled, but since there's no real external exhaust manifold, claiming that it too is water-cooled is nonsense.

That's not the exhaust manifold...

The Z4 M40i derivative gains further visual touches including trapezoidal exhaust tailpipes. The car is powered by a 3.0 straight six engine. This twin turbo, direct injection unit has design features including water cooling for its exhaust manifold.

Plunging the hot exhaust passages through the cylinder head's coolant paths allows a cold engine to get up to operating temperature much more quickly, reducing wear and improving fuel economy. It also reduces exhaust temperatures, a task that's usually accomplished by running a richer (and thus less economical) air/fuel ratio. Lowering exhaust temps helps extend the life of the catalytic converter, too, and the short distance between exhaust valves and turbocharger improves throttle response and power output. Volkswagen first started using this type of design in 2013, as did Ford with the EcoBoost three- and four-cylinder engines.

Of course, there are potential drawbacks to go along with the benefits of this unconventional exhaust setup, mainly in the form of increased load on the cooling system. And the integrated exhaust manifold makes it nearly impossible for tuners or the aftermarket to come up with a higher-flowing header design—changing the manifold would require completely re-engineering the cylinder head.
Doesn't sound good for us tuners...

6 to 2 Exhaust manifold "cooler". Looks to be built into the engine head meaning it cannot be removed, only bypassed. It's sole purpose seems to be saving the catalytic converter. :dunno:

I've based the premise of my post on the parts drawings that were leaked on realoem.com. There is no proper external exhaust manifold on the A90's variant of the B58 engine.

Yes, the exhaust makes a tortuous path through the head (which is of course water-cooled), but that's not the same thing as a watercooled exhaust manifold. No matter what automotive journalists write.
