I just got a 91 SI trany and a ZC engine and need to know what clutch parts to get? Thanks!

 

If his ZC has the flywheel just buy a 91 Si clutch, the flywheels are the same. Starters are the same, clutches are the same. 88 is the only odd year where you would have to change the flywheel too, because no 88 had the larger diameter clutch. the 91 Si was, thats what I have on mine, ZC flywheel 91 Clutch, had a 89 and a 90 Si box both were crap (long story-involved fraud) got a ZC trans and kept everything I had, and I had the '89 DX starter.

 

I forgot to mention that the place I got it from did not give me a flywheel. All i have it the HF one....should that have come with the engine? Can I use this one? I know I'm sure it's not the same size as the SI but will it fit?

I would venture a guess and say a definate maybe. I am sure the HF has the smaller clutch. It may work if you go with a really good Aftermarket clutch. an OEM type clutch will slip on you. THink the hf has the same clutch as a DX, STD. not the larger diameter one. I have a B&M and it slips when I get on it. and I did take it easy for a 1,000 miles after it went in and I did have the original ZC flywheel resurfaced. And I do have the larger clutch. Anyone confirm the HF flywheel issue? Same or different than the DX? Never saw one myself for a compairison. I know the ZC has the same flywheel as the '91 Si. and I do know a '89 DX flyswheel will work but it has a smaller diameter clutch. But if you went with Exidy , Clutchmaster or one of the others (I forget which ones were best) you should have few problems. But I would want to know from someone who has tried or done this for themselves, HF to ZC. I only have experience with the DX to ZC swap. And I know A DX starter a DX flywheel and a DX clutch would have worked. I still have the DX flywheel in my garage, My engine came with a flywheel.

I'm honestly not 100% sure, but from what I could tell on the autozone website, all 1991 2 wheel drive clutches are the same, so if the aftermarket replacement is universal, I'm thinking you should be able to use a resurfaced HF flywheel.

DON'T GO STRICTLY ON MY RESPONSE THOUGH!!! I really don't know for sure.

 

I'm going to Autozone today to talk to them...can anyone else verify that this will work? Thanks for the imput!

this one says it is for 1.5's AND 1.6's...I guess that means that you can go from a 1.6 to a 1.5 clutch.

He's got a '90 hf not a 92. I think the HF has a 110mm clutch the 90-91 Si was 118mm if I remember but it is larger for certain than the DX and STD. It has to match the flywheel, only '88 had a different spline count on the shaft. I have matched up DX and ZC flywheels and clutches. Mine came with a Flywheel and clutch still on it. THat flywheel is a perfect match for the newer Si but has a larger clutch than the '89 DX and I am certain the HF also., If the clutch application shows the same part for the 90 Si and HF and DX I would be highly surpised. I know for a fact the '89 is smaller. If he keeps his HF flywheel thats the one a clutch has to fit. I took my flywheel to the parts store to match up the size. THats how I know the ZC came with the same clutch as a 91 Si. Thats the one that fit. and I knew it was larger than my stock DX clutch as I had them side by side.

 

The 1990 HF, DX and Si all use the same clutch and flywheel. This is based on the Majestic Honda website.

 

Ok then '89 was the last year where they were different. If the Book shows the HF and Si clutcj being the same then use your flywheel and starter, save money. But do the new clutch before it goes in I did the piolot bearing too just to be safe. Its a pain in the *** to take apart for just a clutch 6 months from now (in middle of winter) because you wanted to save money now by using an old clutch (not that you intend to, just making a point).

 

My as well have the flywheel resurfaced while you are at it. Virginia Dude is right, changing the pilot bearing is a good idea too.

 

I agree, and I am going to get a new clutch assembly and not use my old one to save some $$$$. I just needed to know if I should get the SI of the HF one. Thanks for all the help.
