How do I know what size injector to get?

Fuel Injectors are sized by their flow rate. Flow rate is a measurement of how much fuel can be delivered over time. It is listed in pounds per hour (lbs./hr.) or cubic centimeters per minute (cc/min.). The right size injector can supply enough fuel under full load conditions at an 80% duty cycle.

How much horsepower does a H23 VTEC have?

197 hp
The H23A DOHC VTEC Engine is largest displacement in the H Series engines with a compression ratio of 10.6:1. Found in the Japanese 1998-2002 Accord Wagon SiR (CH9). It produces 200 PS (147 kW; 197 hp) @ 6,800 rpm & 163 lb⋅ft (221 N⋅m) @ 5,300 rpm and comes with a “blue top”.

What size are RSX injectors?

They are 310 cc.

Can you run bigger fuel injectors on a stock car?

You can;t do a stock tune unless you can fool the ecu into thinking it is getting more or less air. If you throw in bigger injectors it will hold that injector open for the same amount of time as the smaller injectors and it will dump TONS of fuel in.

What size are K series injectors?

They are a 48mm long body, shorter than normal injectors. The adaptor tops make them “normal” 60mm length and adapt them to 11mm (B series) or 14mm (K series) orings. The K series guys can run the injectors with no adaptors at all and they are the same length as the OEM rsx injectors so no spacers needed on the rail.

What size are RDX injectors?

410cc
OEM (Denso) Acura RDX injectors. These injectors are rated for 410cc (at 38 psi) and 550cc (at 70psi) and offer a much improved spray pattern over the factory Type-S (310 cc) injectors. These features offer the K-series engine increased fuel flow and better fuel atomization.

When did the Honda H23A VTEC engine come out?

In 1998, Honda of Japan produced a rare DOHC VTEC version of the H23A engine for use in Japan only. It has been factory modified with an internal oil passage in the H23A block to operate the VTEC solenoid in the H22A head.

What is the difference between H22A and H23A DOHC VTEC?

The H23A DOHC VTEC has 87mm x 95mm (bore and stroke) and the H22A DOHC VTEC has 87mm x 90.7mm (bore and stroke). The H23A DOHC VTEC Engine is largest displacement in the H Series engines with a compression ratio of 10.6:1.

What is the size of the valves in the H23A?

Therefore, H23A engines lost power and aggression. The diameter of the JDM H23A intake valves is 35 mm, of the exhaust valves – 30 mm. In the versions for USDM and EDM, 34 mm inlet valves and 29 mm exhaust valves were used. After every 25,000-30,000 miles, valves are to be adjusted.

How much CC is the displacement of the H23A engine?

To obtain 2.3 liter of displacement, they inserted a 95 mm stroke crankshaft and pistons with the compression height of 30.5 mm; the rod length was decreased to 141.5 mm. All together, it provided the displacement of 2,259 cc. Cylinder head H23A has a typical DOHC design: two cams and 4 valves per cylinder.
