I know the post is long but still read it and try to help; I did search and couldn't find what I needed. If you don't want to read my little story, my questions are at the end of the post.

I have a B16A with LSD that I am trying to swap into my civic (94 DX Coupe). The swap is from Hmotorsonline for those who want to know. Anyway, I figured I might as well check the clutch while the engine and tranny were out of the car. It turned out the clutch assembly on the B16 was in bad shape. I was planning on getting a new clutch and what not while the engine was out anyway, and I didn't want to have a heavy clutch pedal. I called up my Honda dealer and ordered a clutch, pressure plate, release bearing and pilot bearing, for a Del Sol VTEC.

I took the flywheel to my local shop and asked to have it resurfaced. The guy there said that resurfacing it could be a bad idea (long story short – the flywheel is very worn) and said that a remanufactured one is 50 dollars. So I thought whatever, ok, order me one. It came in and it looked new, and it was right except it was missing some holes for my pressure plate to bolt to. My flywheel has 9 holes, the one they got had 6. The presure plate I ordered for Honda has 9 holes for bolts. I said I'm not putting a car together with bolts left over, and that Honda made them with nine bolts for a reason, I don't want it.

Next I ordered a flywheel for a Del Sol VTEC from Honda. It too had 6 holes. I ended up ordering another flywheel. This one was for a 2000 Civic Si, based on their recommendation. Honda got it in and what do you know? It, too, is missing a third of the bolt holes that my original has (i.e. it has six, not nine bolt holes.)

So now I don't know what to do. I haven't bought a new flywheel (yet) or resurfaced the old one. And my questions are these:
(1) Can I order a flywheel for Honda or Acura that has nine bolt holes?
(2) I don't want to get a lightweight one, I think they are easier to stall and I will drive this car daily, but how many holes would they have?
(3) If I do end up getting a flywheel missing a third of the holes, how much do I torque the bolts that are there to?
(4) Am I getting flywheels for a D series instead of a B series?

I have been trying to figure this out for about two weeks now and it is getting very frustrating.

 

no nothing was wrong with any of em

some of the holes on the pressure plate are for the allignment studs on the flywheel. and yes the flywheel only takes 6 bolts the other three are just there to keep it in place while you put the bolts in

 

When I pulled the flywheel off I took off nine bolts, so I thought that I should use them all to put the flywheel back on. The pressure plate has a total of nine bolt holes plus the three holes that the studs on the flywheel go through. When I put the pressure plate on the flywheel it did line up just fine on the studs, and it lined up with six of the nine bolt holes (the others were missing). But what you said does makes sense, because the casting number on the new flywheel was the same as the one on the engine. So if the number of bolts on the flywheel can be reduced by one third safely, why did Honda use nine bolts in the first place?

 

factory b series flywheel

 

Bump. I want to know why there are only six holes for bolts in a new flywheel from Honda, but an origonal one had nine.

 

rev high and fast,

 

you'll be fine i my ACT has 6
