This page is for personal, non-commercial use. I liked the simplicity. Everything was easy to use, whereas newer cars have a bit of a learning curve with infotainment systems and whatnot.
The red stitching and WRX-embroidered seats added some uniqueness to the car. There was a rattling sound coming from the driver's side A-pillar that I had to fix.
Subaru did a good job with the new model's interior. It feels more elegant than aggressive. The climate control knobs have a nice feel and weight to them, and the steering wheel is superb. There's a digital display on the gauges, a small screen on top of the dash, and Subaru's Starlink system for radio and phone.
A back-up camera is standard and displays on the Starlink's 6.
Plenty of headroom and legroom, too, not that the old model felt cramped. This could be remedied with some modifications, but I wasn't really interested in that, especially considering it was a leased vehicle. I think a stickier set of tires would have added some heft to the steering. I wouldn't call it sports car handling, but there's less body roll, and the steering feel and precision are great. I can fling it around corners faster than the old model. This car is very maneuverable and a pleasure to drive.
It also had unequal-length headers, providing the famous or infamous "boxer rumble. I had the base factory exhaust, so the sound was only for driver and passengers to enjoy. Even though this engine is lambasted for being old tech, I liked it overall, except that the turbo lag could get annoying. It has equal length headers, allowing for better performance, but gone is that rumble. I kind of miss the sound of the old EJ25, but the new powerplant is smooth and slightly more fuel efficient although fuel efficiency is a moot point when purchasing a performance vehicle, in my opinion.
Crawford Built Short Block: STI (EJ257 )
The new model doesn't sound bad, just not as throaty; the turbo sound is actually more pronounced, which I like. More importantly, the torque comes on earlier with the FA20 and turbo lag is not quite as bad. Transmission For the — model years, the WRX was only available with a 5-speed manual transmission.
It wasn't horrible, but it wasn't that crisp, either. Many people described it as being notchy. I had the factory short-throw shifter, which was decent, but still could have been smoother in its shifts. Which one did I choose? Well, it was a difficult decision, but I went with the CVT. Sacrilege, I know, but my long commute was making daily driving a stick shift sort of a pain. I did test drive the 6-speed version before settling on the CVT, and the shifts felt pretty good.
I just decided that with my situation and at this point in my life, an automatic would be more convenient. Before people get up in arms, I'll be the first to admit that the manual version of the car is cheaper, lighter, and more engaging to drive.Herb importers in usa
I miss it. The row-it-yourself WRX is faster off the line, too, but keep in mind that a really quick 0—60 time requires an aggressive, clutch-abusing launch.
Having said that, I'm glad Subaru is offering an automatic transmission for those whose circumstances necessitate it. It's not bad, either. The simulated shifts between gear ratios may seem gimmicky, but it's entertaining and helps keep the engine in its powerband.
If you need some power, a quick jab of the accelerator does the trick there are paddle shifters as well.All components engineered and manufactured by Crawford Performance have been tested for ultimate performance and maximum dependability on and off the race track. For over 2 decades we have tested all combinations of upgrades for the turbo-charged EJ20, EJ25, and more recently the new FA20 Subaru engines. We have pushed these engines to their breaking points to determine which components fail at what level.
From that research we have come up with forged internals to keep your engine strong enough to withstand your desired power level. We recommend that certain parts be replaced new when installing a new Short Block in to your vehicle.

Footer menu Search About us Contact Us.Subaru introduced the FB20 in as a replacement for the very outdated EJ engine family. The FB20 was designed with economy in mind and features many technologies that allowed Subaru to improve their fuel efficiency. Just like many Subaru engines of the past, the FB20 is a flat four-cylinder engine.
The cylinder block and cylinder heads are made of cast aluminum to help save weight which also increases efficiency. The flat engine configuration helps keep the center of gravity low which inherently improves handling. Subaru focused on creating a very lightweight rotating assembly to help improves efficiency. The connecting rods are asymmetrical and the pistons are extremely lightweight.
Subaru also changed from a belt-driven valve train to a chain-driven valve train.TURBO BRZ VS. WRX FA20 Engine Comparison
This allowed them to decrease the angle on the valves allowing for a smaller cylinder bore. With that smaller bore came a slightly larger stroke which further increased efficiency.
The EJ engine family came in pretty much every Subaru produced after Although the FB series is fairly new, it will likely follow in the same footsteps of the EJ. Since Subaru wanted this engine to achieve excellent efficiency they used a lightweight rotating assembly and a high compression ratio.
Those lightweight pistons, however, are known are having poor oil rings. Poor oil rings results in excessive oil consumption as mileage increases. Other than the oil rings the FB20 is a pretty reliable little engine. For this reason modifying the FB20 engine is pretty much never done. A simple intake and exhaust may pick up a couple of horsepowers, but anything past that is a bad idea. Save my name, email, and website in this browser for the next time I comment.

Such builds are made to be the cutting-edge of what can be done with that platform. There are no limits. Every part for that car is intended to be the best one possible, showing that the company is only in it to outdo everyone else's build.
To display the essence of its business, L. SLEEVE has been in the business of sleeving engines for both performance and repairs for over seven decades. To truly show what the performance side of their business is all about, a stock Subaru BRZ was the car of choice, but the word "stock" was soon to vanish from the conversation.
Many have argued that the 2. The FA20 delivers horsepower and lb-ft of torque, which makes the 2,lbs car more of a momentum car. Momentum is not what we are looking for, however, and since the L. SLEEVE build will serve as a demonstration of power and capability, we had to take the BRZ to completely new heights and force some much-higher power out of it.
In issue"Stop the Swap," we focused on the FA20 and why you should consider rebuilding one of these engines instead of performing a motor swap. While tuners have chosen to swap the 2.
The goal is to build a complete, powerful BRZ that can not only reach the whp mark, but to also handle just as well. So, before starting on the engine, we turned our attention on the chassis, suspension, and brakes with the help of Peter Yeung at LMR Development to better handle the increased engine performance.
Now, we propose a supercharged 2.
For any well-built demo-car, the goal is not to show how fast the car can go from 0 to 60 mph. The goal is to show how complete the car is.
We will be increasing the engine power by almost three times that of stock, which means we had to lower the car's height to improve its center of gravity and improve transitional weight transfer rates under various racing driving modes.
Whiteline MAXG were chosen for our coilovers.
FA20DIT vs. EJ257
The MAXG offer mm height adjustment for both the front and the rear, allowing us to control the height for various racing needs. The coilovers feature a The extra width on the dampers strengthen the hardware, enabling them to withstand higher lateral forces during hard corners. This also comes with the benefit of heat-dissipation characteristics to keep the shocks performing reliably and consistently. The MAXG coilovers from Whiteline were chosen for their ability to maintain suspension geometry under heavy lateral and braking loads on the track without being overly stiff when driving on the street.
In order to improve the suspension further, we had to get rid of the factory bushings. The stock bushings are made from fairly soft rubber that serve the stock car well, simply incorporated to absorb the energy transmitted from the road to provide a comfortable ride on the streets.
However, as the engine power increases, we have to anticipate the high speeds and quick maneuvering. We replaced the stock bushings with ones from Whiteline.There is no standard warranty on any Crawford Performance Built short blocks.

Making more power starts inside your engine. The Subaru EJ Series Boxer engines have propelled numerous Subaru platforms in world class motorsports competition and many thousands more on the street. Delivered from the factory with anywhere from to horsepower the latter powering the latest STIthese engines were notorious for oiling issues, block distortion under heavy loads and cast pistons that suffered from failed ring lands that eventually led to a blown engine. For its next generation of Boxer engine, the FA Series, Subaru made some distinct refinements to its design.
This new 2. Its cast aluminum pistons feature a specially designed dome intended to optimize combustion of fuel delivered by the direct injection system. These pistons make the connection to the crankshaft by way of asymmetrical connecting rods designed to reduce friction and wear on the cylinder walls and the piston skirts during the compression stroke.
Direct Injection fuel delivery technology lends to improvements in both output as well as fuel efficiency. Since the FA20DIT engine is still a relatively new mill, it leaves many wondering what its strengths and weaknesses are. Only a handful of owners have been willing to push their new cars to the edge of the envelope or beyond while still under warranty.Recovering windows after installing ubuntu
The good news is that Subaru seems to have improved on its previous design, engineering what appears to be a more robust and capable powerplant. Few have reported issues relating to ring land failures or block distortion, as was the case with the EJ engine. Some premier Subaru tuners have already pushed the factory internals to approximately to lb-ft torque at the wheels.
However, this appears to be the comfortable limit that most tuners are unwilling to push past on a stock block, as even a strong factory engine has its limitations.Fosrestbundle tutorial
Eclipsing the lb-ft torque level with repeatability and reliability requires fortification of the rotating assembly. This is especially true as some tuners have noted that the offset connecting rods are susceptible to bending or breaking when subjected to excess boost at lower RPM i. In addition to the connecting rods, the factory cast pistons are also a potential point of failure when exploring output levels more than twice that of a stock engine.
Just like our presence in the EJ series, we wanted to fully support all the new FA series engines, making development of this piston line a natural choice.
The FSR forging features narrower pin boss and wrist pin for reduced weight, while a specialized 0. Previously, this required looser tolerances to allow for piston expansion once warmed up. This trade-off resulted in piston slap and premature wear on the piston skirts and the cylinders during warm up. With Perfect Skirt, pistons can be installed tighter, without any risk of damaging the cylinder bore. When it comes to direct injection engines, the piston dome design is paramount, as it must reflect the atomized fuel toward the spark plug to be ignited.
This design is unique to the FA20DIT and draws on the factory shape for optimal fuel atomization and combustion. Blog home Product lines. By Richard Fong. Since, the engine has been enlisted to power a slew of Subaru vehicles. The renowned low center of gravity that boxer engines are praised for has been a key element to their handling prowess through the years. They are purpose-designed for competition and high-horsepower engines. Left, a factory piston has reached its critical limits blowing a chunk out of the skirt.
Right, note the unusual orientation of the stock FA20 connecting rods. This relocates the pin-bosses inboard to shorten the length of the pin and reduce mass. This bowl is precisely maintained to facilitate proper fuel dispersion from the factory direct injection system.I did not approve it since it read like a year-old wrote it.
About the data: there are many places on the internet where you can get hard data. In fact, there are several magazine articles that I reference on this blog that have data.
Subaru EJ engine
The thing about data is that it can be read in many ways when using it as support media. You can also make pretty accurate assumptions from the gaps within the details. We know what will fail. It just means that we know where the issue will occur and will know how to deal with it when it appears. Maybe 10 years from now, though. What you do in your own garage is your business. The EJ has been used going on 15 years, with wide aftermarket support.
Who tunes the engine after adding the power-adders that will make the engine just as powerful as the EJ variant that resides in the STI? Either the owner or a tuning specialist. As well, even if tuned, a WRX will still lack a robust 6-speed transmission. The new 6-speed in the WRX is still glassy…up the power and risk your transmission.
It is also still cable actuated. STIs will also eventually cook their brakes again, it depends on the track but not as drastically as the WRX. The first thing that comes to mind is the ringland issue that EJs tend to have.
What do I mean by this? Change your oil as recommended in the manual. Check the oil religiously and ensure the oil is at a satisfactory level.
