I have a 95 Integra gsr and I'm doing a b18c longblock from japan. I'm relacing the IM to a skunk2 and I just received my exedy clutch and flywheel to be installed at the same time. The company is suggesting that I change out the rear, front main seals, and camseals,etc while the motor is out and apart. I'm also having my timing belt, water pump and tensioner replaced. Although this seems like a lot to do, I think it's a relatively easy install considering 90 percent of the work will be done out of the car. The company that is doing the install is very reputible(they've done work for me before), but they want like 1000 to do this. Is that too much?
