This can be a very difficult exchange if you try it without any instructions or instructions. However, these step by step instructions can make it easy. The H22 engine in the CRIS 88-91 or CRX chassis exaggerates the old theory of power to weight for incredible acceleration.
Let's start with the fact that you have already removed the stock engine. We will begin this engine exchange by preparing the engine compartment. The first step is to remove the transmission mount bracket, which is welded to the frame. This will require the use of a drill with a large drill bit or an orbital drill for drilling in factory welds and pull this bracket out of the frame. After removal, use a grinder or similar tool to smooth out the frame of any debris or sharp spots left over from the drill bit.
Then secure the passenger's gearbox bracket, which is included in the Hasport mounting kit, to the rear of the passenger frame using the 12-mm battery tray bolts and factory-installed tapped holes. You will need to use a wit or other marker to trace the outline of this bracket on the frame. Remove the bracket and grind or grind paint from the area that you traced to prepare it for welding.
Replace the bracket and attach the bracket to the frame. Be careful to penetrate the weld completely, but do not burn the factory frame. After the zone has cooled, spray the primer over open welds and apply paint to select a color on the primed area to prevent corrosion.
Next comes the hard part. The factory transmissions of the F / H series are very large and will require some modification of the lower part of the rail below your newly installed bracket. This is easiest if you lift the engine partially into place to see which area should be cut off. After reducing the clearance, you will need to make a bracket from sheet metal or similar material to properly reinforce the frame guide. You can skip this, but be careful!
Now, some fun stuff. By this time you are already in a fright in your car, so it will be a light breeze. Use a medium sized sledge hammer and place a large dent in the upper part of the firewall to make room for a huge H22. This can help partially lift the engine in place to understand where to “put” this dent.
Screw the Hasport back mount to the bottom crossmember using the supplied hardware supplied with the Mount Mount. On the belt side of your new H22 engine, remove the timing belt covers and unscrew the engine mounting bracket. Screw the new Hasport engine mount to the installation location and install the factory chrome covers. Covers may require some trimming to clean the work holding bracket.
Remove the H22 vehicle speed sensor and replace it with your factory 88-91 civic / crx speed sensor. It should be right on the spot. The Hasport cable bolt to the hydraulic equipment converter arm to your gear H22. Because of the large size of the H22 engine, you need to either shave the external power steering pulley or install a low-drive crankshaft pulley that does not have power steering grooves.
Screw the supplied Hasport Alternator Bracket to your h22 engine using the hardware supplied with the Hasport H22 mount kit. Then secure the D-Generator Alternator Bracket to the Hasport Alternator Bracket. You may need to slightly bend the measuring tube for clearance. Using the remaining factory equipment, slide the D-Series spare generator upside down onto your H22 engine. For easier installation in the engine compartment, you can wait until the engine is installed on the generator bolt.
Now comes the interesting role. The easiest way to install an H22 engine with the Mount Has Has Mount Kit is from below. You will need to raise the car on the lift and "lower" it on the engine. With the engine close together, slide the rear engine “L” bracket into place using only the two upper bolts. Leave the two lower bolts for the rear bracket until you fix the remaining mounts. Now you can secure the timing belt bolt in place and then mount the gearbox. So far this is only a hand. Return to the rear bracket that secures the engine to the rear mount and install the two lower bolts. Now tighten all engine mounting bolts to factory specifications.
For wiring, you will need to modify your spare engine harness to match the Prelude engine. For simplicity, you can also purchase a new special wiring harness. The axles that you need to use are made by Hasport and must be installed using an H22 intermediate shaft.
