How to Swap an H22 Into a CRX Chassis Using a Hasport Mount Kit
This can be a relatively tricky swap if making an attempt it without any guidance or direction. However, these stage-by-action directions can make it a breeze. An H22 engine in an 88-91 civic or CRX chassis exaggerates the outdated power to bodyweight ratio concept for unbelievable acceleration.
Let us start out with assuming you have already taken off the stock motor. We will start this engine swap by prepping the motor bay. The to start with action is to clear away the passenger side transmission mount bracket that is welded to the body. It will require the use of a drill with a substantial drill little bit or place weld drill little bit to drill by means of the factory welds and take away this bracket from the framerail. Right after removing, use a grinder or identical software to easy the framerail of any debris or sharp places still left from the drill.
Future, bolt the passenger facet transmission bracket that is incorporated in the Hasport mount package to the passenger aspect framerail working with the 12mm battery tray bolts and factory threaded holes. You will have to have to use a sharpie or other marker to trace the define of this bracket on the framerail. Clear away the bracket and grind or sand the paint from the region you traced to prep it for welding.
Bolt the bracket back again into area and stitch weld the bracket onto the body rail. Be careful to absolutely penetrate the weld, but not burn off as a result of the factory body rail. Following the space has cooled, spray primer above the uncovered welds and apply your color preference paint more than the primed space to avoid corrosion.
Next will come the difficult section. The manufacturing facility F/H series transmissions are very substantial and will have to have some modification to the decrease portion of the rail under your freshly installed bracket. It is best if you elevate the engine partly into put to see what space needs to be lower. After chopping ample clearance, you will want to fabricate a brace out of sheet metallic or similar substance to properly fortify the frame rail. This can be skipped, but be advised!
Now, some entertaining stuff. You will have by this time already gotten around the fright of slicing into your auto, so this will be a breeze. Use a medium sized sledge hammer and place a large dent in the higher part of the firewall to make place for the large H22 consumption manifold. It may perhaps aid to partly carry the engine into location to get an idea the place to “place” this dent.
Bolt the rear Hasport Mount onto the reduced crossmember using the equipped hardware incorporated with the Hasport Mount Kit. On the timing belt aspect of your new H22 motor, get rid of the timing belt covers and unbolt the factory engine mount bracket. Bolt the new Hasport motor mount bracket into position and reinstall the manufacturing unit timing covers. The handles may perhaps need to have slight trimming to crystal clear the billet hasport mount bracket.
Take out the H22 transmission auto velocity sensor and replace with your manufacturing unit 88-91 civic / crx cable driven velocity sensor. This should be a immediate suit into place. Bolt the Hasport cable to hydro conversion lever assembly onto your H22 transmission. Due to the substantial measurement of the H22 engine, you will have to have to possibly shave the outer power steering pulley, or put in an less than-travel fashion crankshaft pulley that does not have a electricity steering groove.
Bolt the involved Hasport alternator bracket onto your h22 engine utilizing the hardware equipped with the Hasport H22 mount package. Then bolt your manufacturing unit D collection alternator bracket to the Hasport alternator bracket. You could need to have to a little bend your dipstick tube for clearance. Employing the remaining manufacturing unit hardware, bolt your inventory D collection alternator “upside down” on to your H22 motor. For simpler installation into the motor bay, you can wait until finally the engine is mounted to bolt on the alternator.
Now arrives the exciting part. The easiest way to put in an H22 motor utilizing a Hasport Mount Package is from the base. You will need to carry the automobile up on a hoist and “decreased” it down on to the motor. When the motor is practically in place, bolt the rear engine “L” bracket into spot utilizing just the two higher bolts. Go away the two reduced bolts for the rear bracket out till the other mounts are bolted in. You can now bolt the timing belt aspect mount into location, adopted by the transmission mount. Only hand tighten these for now. Go again to the rear bracket that bolts the engine to the rear mount and put in the two decrease bolts. Now tighten all of the motor mount bolts to manufacturing facility specs.
For wiring, you will have to have to modify your inventory motor harness to in good shape the Prelude motor. For simplicity, a new customized wiring harness can be also acquired. The axles you will need to have to use are custom made made by Hasport and are to be mounted using the H22 intermediate shaft.
