The compression ratio was reduced to B16A2 — here camshafts with the following specifications were used: duration at. The compression ratio was B16A3 — this motor was designed for Honda Del Sol. The power was HP 7, rpm, and the torque was Nm 6, rpm. The power was HP 7, rpm; and the torque was Nm 6, rpm.
B16B was top version of B They decided to use a B18 cylinder block with the height of The size of fuel injectors was cc; the flywheel weight was 7 kg. Specifications of Type-R B16B camshafts are the following: duration at. Attempts to improve this engine were successful, and B16B power reached HP 8, rpm, the torque of Nm 7, rpm, while the redline was set to 8, rpm.
B16B head may be identified by a red valve cover. This may sound strange, but these engines have no problems and weaknesses; B16B and B16A are incredibly reliable and durable engines. However, long time has passed, and all these B16 engines are already worn out, and any component may fail. You just have to regularly and with good quality perform maintenance of your B16A or B16B, and they will run a bit longer.
The best mods for a regular B16A are a cold air intake system, B18C 98 Spec R exhaust manifold or another manifold and a 2. This will give you up to HP. Want HP and more? Hondata will help you configure all these performance parts. Still want more? These upgrades will let you get HP or a bit more.
This is the limit for this engine that may still be used for daily driving. Then you will have to increase the bore to 84 mm. This is best done by replacing the native cylinder block with a B20 cylinder block. However, such a hybrid will not last long; you need to buy aftermarket rods, pistons and sleeves.

In some cases, as the factory ECU is locked flashing is not an option, so an aftermarket ECU is the route to take, and many of these will outperform factory ECU's but make sure it has knock protection and that you get it setup properly. Air Intake manifolds take the air during the suck phase from the air cleaner and allow it to be pulled into the engine and mixed with fuel. Design and rate of flow of the Air Intake manifolds can make a noticeable difference to fuel atomization and engine efficiency on the B On popular production engines intake headers are in dire need of aftermarket tuning parts, although some manufacturers provide reasonably well designed intake headers.
Big valve conversions on the B16, getting port work and head flowing will also improve power, and importantly will afford you a better power increase on other parts.
The more air to get into an engine, the more fuel it can burn and uprating the induction with a turbocharger upgrade makes massive power gains. NASP engines need quite a lot of work when you add a turbo, so we have a separate guide to help you take into account the pros and cons of going this route on your B There are reliable limits for every engine, with some being incredibly solid and some only just able to handle stock power.
We recommend you find these limitations and upgrade to higher quality crank and pistons to utilize the power. It's not unheard of people spending a lots of money on turbo upgrades on the B16 only to have the B16 go up in smoke soon after it's been finished.
Going up you'll find 4 bar air sensors coping with quite large power gains, whereas the OEM air sensor limited bhp at a much lower level. Adding a supercharger or additional turbo will make large power gains, although more challenging to get working. We have a twincharger power adding guide if you want to read more. Don't forget to improve the fuelling when you are increasing the bhp and torque - it makes the car more thirsty. You should look to boost your exhaust if your current exhaust is actually creating a flow problem.
On most factory exhausts you'll find the flow rate quite well even on modest power gains, but when you start pushing up the power levels you will need to get a better flowing exhaust. Do not go with the largest exhaust you can get this will reduce the exhaust flow rate - the best for power gains are usually between 1. It is the shape and material more than the bore size. Common exhaust restrictions can be traced to the emissions filters installed, so adding a higher flowing race alternative such as a sports catalyst pretty much removes this restriction, thanks to it's larger size and surface area, and will effectively raise the performance to levels you would expect without having a catalyst installed, but keeps the car road legal.
The B16 engines are generally extremely reliable and solid as long as they are regularly serviced and maintained. Problems and weakspots are thankfully unheard of if the car is well maintained and looked after. Regular oil changes are vital on the B16, especially when tuned and will help extend the life and reliability of the engine. Camshaft seals can leak, they have been known to burn oil, especially if not properly serviced and looked after.
