Default ACT Clutch/Flywheel

hey everybody, I have a question regarding ACT clutches and flywheels. I have a '95 Impreza with a 1.8 that I will be swapping out in favor of a buddy's '97 2.2 set up. I am planning a build for the 2.2 in the near future, so I'm buying a clutch that will handle my hp goal now, rather than later.

The part numbers I'm interested in are as follows:

Flywheel - #600185
Clutch - SB2-HDG6

Upon doing more research, I found out that those parts have diameters of 225mm. The '91-'94 Legacy turbo parts are 230mm:

Flywheel - #600175
Clutch - SB3-HDG6

Could I run the Legacy parts in my 2.2l setup [engine & trans]? I will be purchasing a Ver. 3 or 4 swap in the spring, will this clutch setup work with an STi transmission? If I chose to upgrade to a 6mt later, will I need a different clutch setup? Thanks in advance for any advice!

p.s. I've been searching for these answers for like 2 weeks already. sorry if there is already a post similar to this in the archives, must have missed it.

Out of curiosity, were you searching in the transmission forum instead of an engine forum? Just asking.

You can put any push-style clutch/flywheel combo in any car with an EJ-series motor that came with a push style in it as long as you keep the components together, with the exception of the Legacy GT turbo/'06+ WRX push style setups. E.g. something for a first gen Legacy turbo will work on any NA Impreza.

I was searching all forums I could think of. Different sites, etc.. You never know where the answer will turn up, and I've built a few cars, so I'm pretty familiar with searching the usual channels.

I appreciate the information. Sounds like I'm looking for a parts-matching 'push' setup. Thank you for answering my next question in advance!

The flywheel is a good choice. The clutch, not so much. Save yourself a ton of money and quite a bit of hassle during driving and get the Exedy Daikin OEM clutch kits off Amazon.

As far as fitting, you'll be fine so long as the clutch disc, clutch pressure plate, and flywheel all match up. Assuming your clutch is push-type, you could easily use the ACT 600185 fly and Exedy KSB04 clutch kit and you'll be good to go.

ya, the OEM exedy/daikin kits are a great value, and what I use in all my oem/light-street builds. However the one currently in my 1.6l miata w/fidanza flywheel started slipping after about 10k mi of hard driving. There is absolutely no way whatsoever that an OEM clutch will hold up to the 350+ hp ass-whipping I will be bestowing upon it.

If your OEM clutch was designed for a tiny NA engine with torque in the mid-hundreds and now you're using it on an engine with torque 150-200lbf-ft above that, you'd have to be an idiot to think it was going to last.

lol pretty much what I was thinking. car will be boosted before summer, so I can deal with a couple months of difficult driving before the power gets here And like I said, I've built a few cars, I know exactly what I'm getting into here...
