Like most things in. There are many paths to turbocharging. Bocage O Triunfo Do Amor Download Adobe here. You can use the best parts money can buy or you can use junkyard parts.

To many times. I have heard people complain about how poorly their system performed, or how. Hondas are unreliable.

If done correctly a turbo Honda can be just as. The key is research. An excellent source of information.

Though not specific to Hondas, this book is one. This FAQ does not cover supercharging. Integra. The Jackson Racing SC does not clear the fire wall on. Integra, there is also an issue with brake master cylinder clearance. One G2. IC member.

The relevant. information can be found here: http: //www. Information on an attempted Jackson.

SC install can be found here: http: //www. Contents Turbo. Basics: The mechanics of a turbocharger are closely related to the mechanics of a jet. If you were to modify the turbo so that the compressor outlet fed the turbine inlet you would be on your. A turbo's relationship with a jet engine should. A turbocharger harnesses. The exhaust flows through the.

After going through the exhaust. The turbine is connected to the compressor wheel on the intake.

The center housing will. The above. picture does not show ports for water. Fresh air is brought into the turbocharger. The air is compressed by.

Above we see the basic layout of. Exhaust gases leave the engine via. One thing. missing from the above diagram is an external wastegate. The wastegate is used. In a. turbo Honda, the turbocharger is bolted directly to the manifold.

After moving. through the turbo, exhaust gasses exit the turbo through a downpipe which connects. Fresh air ,after being compressed by the. An intercooler works exactly like a radiator except pressurized. The intercooler is mounted on the front. This cools. the pressurized intake air charge.

This is necessary because when air is pressurized. Another component missing in the above diagram is a blow off valve. BOV). The blow off valve vents pressurized air when the throttle plate is closed. Another component not shown is. POV). Often not used on turbo Hondas, a POV is a safety valve. This prevents an overboost.

Back. to Top. Setting a Realistic. Goal. It is very important to establish. You should consider your budget and also. Do not base your goals on a certain PSI. PSI. is not a valid consideration because the turbo determines what PSI will result. For instance 1. 0psi on a tiny T2. Also keep in mind that generally the higher.

Be. realistic when setting the horsepower goal, 3. Honda is A LOT of power for the street. It is a good idea to keep in mind.

Many. people setting out on the forced inducting path throw around horsepower numbers. Back to. Top. Component List: Other. Things to Consider. Engine: There are many decisions that need. These options include whether or not to go with a stock motor or a motor. Whether to run the non- VTEC LS, VTEC, or LS- VTEC.

Realize. that an entire guide can be written on this topic, as such, no attempt was made. This section will present the advantages and. B1. 8A/BThe B1. 8A/B is an excellent engine. Integras come with. The stock compression ratio, at 9. The horsepower to torque differential, on average.

LS motor (stock stroke and displacement) and 2. VTEC equipped. counterpart. This motor is particularly reliable as well. Stock LS motors have. Boosting at these.

Built LS motors have seen 5. B1. 7The B1. 7, which came in the 9. GSR, is a VTEC motor which has some characteristics that need to be addressed.

The 9. 7: 1 compression ratio must be kept in mind when tuning. With the higher compression ratio less boost will be required to reach. Also, due to. the VTEC system, cam timing on the B1. Reversion occurs during valve overlap and exhaust. Obviously this is not a good thing.

Fortunately with the. B1. 7, and all other. VTEC motors, will put out more horsepower with less boost than a non- VTEC motor. Stock B1. 7s have seen 3. B1. 6The B1. 6 is a very common swap into. Integras. As with the B1.

The 1. 0. 1: 1 or 1. With the higher compression ratio, less. Also, due to the VTEC system, cam timing on the B1. The valve overlap, intake and exhaust valves. Reversion. occurs during valve overlap and exhaust gasses are drawn back into the cylinder. It can lead to detonation and generally poor.

Fortunately with the use of adjustable cam gears the overlap can. B1. 6, and all other VTEC motors, will put out more horsepower with. VTEC motor, about 1. Stock B1. 6s have seen. B1. 8CThe B1. 8C is not a very common swap. Integra. However the larger displacement over the B1. As with the other VTEC motors, the B1.

C has some characteristics. The 1. 0. 1: 1 compression ratio must. With the higher compression ratio, less.

Also, due to the VTEC system, cam timing on the B1. C raises. some issues that need attention. The valve overlap, intake and exhaust valves. Reversion. occurs during valve overlap and exhaust gasses are drawn back into the cylinder. It can lead to detonation and generally poor. Fortunately with the use of adjustable cam gears the overlap can. B1. 8C, and all other VTEC motors, will put out more horsepower.

VTEC motor, about 1. Stock B1. 8Cs have. B2. 0The B2. 0 motor is a direct replacement. B1. 8A/B. The only advantage of the B2. LS motor is the extra.

This extra displacement comes at a price. In order to achieve 2. B series sleeves. The. design of these sleeves varies slightly from other Honda sleeves which accounts. A simpler way to achieve the 2.

LS motor and bore it to 8. Also consider that the B2.

LS motor. B2. 0 compression ratios are 8. However it is also the hardest to build so that it runs reliably. By using the LS block. B1. 6 head (with a stock bottom end) a compression ratio close to 9.

If rebuilding the motor, the block can be resleeved with aftermarket. A reliable. LS/VTEC motor is very difficult to build, as such it should only be attempted. LS/VTEC motors. Since building. LS/VTEC motor is such an art, engine builders charge a premium for their. Also keep in mind that the bottom end of a LS motor was not designed. VTEC motors are meant to shine. Stock. Most stock Honda motors take boost.

B2. 0 being the exception). But before hastily slapping a turbo. Any mechanical deficiencies will.

If the compression pounds. Prior to installing the turbo it. Preparation is key in creating a reliable turbocharged. Built. Honda motors built with aftermarket.

The parts needed when building a motor for use with a turbocharger. Crower. and Golden Eagle. JE/SRP. and Arias) with a. Honda crankshaft. With new pistons, a decision about compression ratios. The most popular ratio is 9.

Higher ratios can be used but. With. the higher compression ratio a lower amount of boost can be used to attain a. One advantage to a higher compression ratio is better low end. Since Honda motors use a floating. The two options for doing this are aftermarket sleeves (Golden. Eagle, Benson's) and blockguards (Golden. Eagle, Nu. Formz, STR).

One downside to aftermarket. Another concern is that. Blockguards. fit into the water jacket that surrounds the cylinders preventing them from. Block guards need to be pressed into the water jacket by a machine. One disadvantage to the block guards is that since water flow near the. This hot spot in the cylinder wall expands the cylinder wall which.

Some modification to the head should. The standard port and polish is a good idea as is port matching. Of particular importance are stainless steel.

Stainless steel valves (Crower). This will help to prevent burned valves. Aftermarket cams that are designed.
