Fast road cams are one of the most significant mechanical changes, but they must be installed by someone who knows what they're doing and they are not always easy to source but you might find a local firm to regrind a stock camshaft.

Engine Tunes - engine tuning/remapping provides the most advantage in terms of cost savings, aftermarket ECUs, and piggyback ECUs are all alternatives.

Be sure to keep up with our latest YouTube content and subscribe. Please watch our video which covers the 5 principles of tuning your car. The engine timing and fuel pump and injectors also have an effect on the torque gains you'll achieve.Ī longer valve duration can alter the torque band and on most engines the exhaust and intake durations do not need to match, although most cams and tuners use matched pairs there are some advantages to extending the intake or exhaust durations. This is because a competition cam causes a very lumpy idle, and makes the car more prone to stall or jerk along in stop start traffic, sadly though many ignore this and end up ruining a perfectly good car and having to revert back to a fast road, or OEM cam profile.ĭifferent L15 engines respond better to less aggressive cam durations than others.

You will never find a L15 Motorsport cam is a pleasure to live with when driving around busy urban areas.

In a typical daily driver must carefully try to optimize your bhp range to your cars usage. Motorsport and race cams, push up the higher rpm power band but as a result the car will not idle smoothly and low end power nearly always suffers. The intake and exhaust durations will alter depending on the chosen cam profile, so large torque gains are on offer for cam upgrades.įast road cams normally push up the bhp and torque through the rpm range, you may lose a little low end power but your higher rpm power will be higher. The cam profile plays a big part in the engines power output so cam upgrades make quite a large difference. Just because particular parts are popular with L15 owners it doesn't mean it is good, instead we will concentrate on the ultimate parts that will give your L15 the best power gain for you spend. Tuning the Honda L15 and best L15 performance parts. The L15 was fitted to the following models

All engines respond well to tuning, but you'll get a lot more power for your money from the turbo units.Ĭheck out our video introduction to Honda Tuning, all you need to know about mods and upgrades on your Honda.

The L15 is the most popular L series engine on our site and we should note that the L15B7 and the turbo L series engines make for fantastic project cars, L15BF, L15B7, L15B9, L15BE, L15BE and the L15BG. The VTEC heads and turbo models are generally the highly sought after items. "Franken builds" are popular with heads, and cranks from other L series engines being swapped to create a higher capacity engine. Let us look into L15 tuning and summarise the optimum modifications. The Honda L15 are popular engines and with carefully picked performance mods like remapping, turbo upgrades and camshafts you will noticeably improve your driving pleasure. We are also sourcing/developing a proper head stud and other components to be able to hold the power as well."All you need to know about performance parts and tuning the Honda L15 engine!" A ~10.3:1 compression ratio is a rather comfortable number for us as well, as it's high enough to keep turbo spool and response there, but not high enough that we are worried about detonation/knock issues. This will be extremely important for fuel atomization and combustion with the direct injection system. We will be working to develop a drop-in piston set designed to mimic Honda's factory piston design. The build will most-likely consist of forged H-beam rods and forged pistons. Our goal is to offer a short block capable of holding ~500 whp. The left side is a 2.0L Type-R piston, right is a 1.5T Si piston. The left side is a 2.0L Type-R connecting rod, right is a 1.5T Si connecting rod.

The rotating assembly can ALMOST fit an a USPS Large Flat Rate Box! Such a cute little factory connecting rod! These pistons also have quite a bit of material between the rings A rather beefy design. The factory piston features a narrow piston skirt with a unique "spotted" friction coating. Honda's past K-Series motors featured a factory girdle system.Īwe look how cute! 73mm Si 10.3:1 compression piston. Also notice the aluminum cast around the top layer of the iron sleeve. Notice the coolant passages at the tops of where the sleeves intersect. We have considered doing a built engine program for the 1.5t, but since then have decided not to further the project.
