Installation Instructions for B-series engines w hydraulic Transmission into 90-93 Acura Integra

For use with Innovative Mounts Conversion Kit Part # 49350 and 49351

Please Read Before Starting: This kit is designed to bolt in B-series engines with Hydraulic Transmission into a 90-93 Acura Integra. Make sure your B-series engine has the left-hand engine bracket (post bracket) from the 90-93 Acura Integra or first generation B16A.

If you need one it can be ordered from us directly or Acura (part # 11910-PR3-010). If you still have it you can also use the original from your 90-93 Integra B18A or B17A Engine.

Before you begin, make sure you also have the proper rear engine/transmission bracket for your engine’s

installation. If your first gen B16A, B17A, or B18A engine did not come with a rear bracket, or you have a 92+ B16A, B18C,

B18B and B20B/Z engine, you will need to purchase one from Acura part no. 50827-SK7-020. It is the rear

engine bracket for a 90-93 Acura Integra. Again if you still have it you can also use the original from your 90-93 Integra B18A or B17A Engine (M/T).

NOTE: The two holes on the rear bracket for the two lower bolts at the transmission will need to be enlarged to accept the 14mm x 1.25 bolts that go with that transmission.

 

Hydraulic conversion installation:
Note: We recomend doing these steps before installing engine into the engine bay.

1. Bolt the release arm lever and bracket to the front of the transmission using the top two of three 12mm

boltholes on the front of the transmission.

2. Install the cable bracket using two 8mm x 1.25mm x 25mm bolts. Torque the bolts to 19 ft/lbs.


Mount kit and engine installation:

Note: We recommend removing the radiator from the car before installing the new engine so that it will not

be damaged. It will also allow for more space to maneuver the engine into place.

1. The rear mount should be bolted into position after the rear cross-member has been altered for

clearance (if necessary). Do not attach the rear bracket to the rear mount at this time. The rear bracket should be

installed later, as the engine is lowered or raised into position. It is best to have help when doing this

if you are installing the engine in from the top. You will need a box end wrench to tighten the rear bolt.


2. If you are installing the engine from the bottom, you can go ahead and install the right-hand mount on

the transmission. If you are installing the engine from the top, you will need to drop the engine down

below mounting position and then install the mount. Then raise the engine back into place while installing

the rear bracket. Do not completely tighten the bolts on the rear bracket yet. Notice the right-hand mount

has slotted holes where the mount bolts to the top of the mount does not line up perfectly the frame rail

bracket you can use slotted holes to shift the mount to the right or left to compensate. This may or may

not be necessary with your car. It depends on your vehicles past history and manufacturers tolerances.

3. Next install the left-hand engine mount, but do not completely tighten the bolts. Use a 12mm x 50mm

bolt and lock nut on the front bolthole and another lock nut on the stud. Make sure you also use 12mm

washers under the lock nuts.

4.  Install the top bolts on the rear engine bracket where it meets the engine and the rear mount. Now go

back and tighten the mount bolts on the right and left mounts. Finally install the two bolts on the bottom

of the rear bracket where it meets the transmission and tighten all the bracket bolts. After 100-200 miles

of driving, check and re-torque all the mount bolts to factory specifications.

Note: We always recommend leaving all bolts finger tight until your engine is properly placed, with the

engine properly secured.

 

Clutch Cable Installation:

1. Make sure the clutch cable adjustment nut is adjusted all the way to the top first, and then slide the

clutch cable through the holder. Now raise the release lever up and slide the clutch cable into the

slotted end. Seat the clutch cable stop into the opening of the lever.

2.  Slide the release rod over the end of the release arm on the transmission as shown and tighten the

bolt until the wave-lock washer flattens completely.

3. Bolt the rod end of the release rod to the release lever and torque to 19 ft/lbs.

4. Adjust the clutch cable adjusting nut as you would normally would for your car. After test-driving the

car, some additional adjusting may need to be done to get the clutch’s release point in the ideal position.
