Hello yall, I know my clutch is on its last leg so wanna install a heavier flywheel when I replace it. Heard nothing but good things about this upgrade. I have a 86 toyota pickup 4x4 with slightly built 22r, running 33s with 4.88 gears. Specifically speaking about ones LCE offers, my question is between the 30lb flywheel using 8 7/8 clutch vs the 35lb flywheel using 9 1/4 clutch (even though the 35lb ones aren't listed anymore) . Is one of those better than the other, is it worth the extra 5 lbs or is there a sweet spot the 22rs like? Apparently I can still order a 35lb one from LCE if I do it over the phone. I know 9 1/4 clutches aren't as common but 93-95 pickups use those, so finding an asin off rockauto wouldn't be too hard. Or are there better heavier flywheels out there yall would recommend?


Thank you all in advance.

 

Whether a heavier flywheel will serve you, or not, depends on what you expect from your truck.
Other things being equal, a heaver flywheel slows the engines ability to accelerate rapidly.
At the same time, a heavier flywheel gives a little more torque at constant revs that helps in slower speed 4wheeling situations.
As for the clutch, I'd probably opt for the bigger one.
You ought to be able to find a standard weight flywheel that will accept the larger clutch.

 

I'm pretty happy with the 30# 8 7/8" setup from LCE with 4.88's and 31's. No opinion on whether the heavier setup would be better since I haven't tried it.

 

I bought my 88 from a friend and it had a heavy flywheel. It was good for what he used the truck for. Mainly driving in sand washes and trails while hunting. It was still the 22RE and W56 B trans at the time with Detroit Tru-Tracs in both diffs, 4.56 gears and 31" tires. It was SLOW to accelerate on the street. I didn't like it and went back to a stock flywheel. It's good for lugging around at slow speed. The 22RE is slow enough in commuter traffic and the heavy flywheel made it slower. Just my experience.

 

Ive accepted that my truck will and always will be a turtle unless i do an engine swap (1kzte down the road). Yeah im looking for some more low end grunt and read around truck with big tires like them. So either way a heavier flywheel is going in my truck.

Aztoyman, u recall what the weight was u had? Im tryin to figure out which to go with (30 or 35lbs). Yeah i dont wanna put on too much weight for that little engine.

 

The heavy flywheel keeps your momentum once you get rolling. It also makes your engine SLOW to rev. It is noticeable, especially on the street. It annoyed the hell out of me. Keep your stock flywheel for a while in case you don't like it.

I'll look through my older posts and see if I can find the weight. It was in the truck when I bought it from my buddy. I think it was either from Downey or NW Off Road??

My 22RE that I built for the truck ran great for a 4 cylinder. It had a 270 cam, bigger valves, blended the bowls and gasket matched the ports, header, 2 1/4" exhaust and even passed emissions. I had 35's and 5.29 gears. GOT RID OF THE HEAVY FLYWHEEL. I could get it up to 100 MPH on I-10. (On my speedometer, I didn't have GPS back then.)

My 3.4 is definitely better though.

 

I found it on an old post on Marlin Crawler. It was a NW Off Road Billet 30 pound flywheel and it had a Centerforce clutch.

 

I appreciate you looking back through your posts aztoyman. That may be the one I go with then since your telling me the difference was pretty noticeable, My engine isnt anything crazy, got new itm head and a 272 cam with some valves from sunwest automotive (already pitting so wouldnt recommend them nor itm heads), offenhauser dual plane intake manifold, hedman header with 3 inch dynomax exhaust I think. Deleted emissions, and a weber 32/36.

Ill def keep it, im still kicking myself for selling the factory carb and intake.

Thanks again for your feedback.

 

I put a Downey 2 1/2" exhaust on my wife's 86 4Runner when the original exhaust rusted out. Completely stock engine. It seemed to help at high RPM a little bit but it absolutely killed the bottom end torque. My wife actually said to go back stock which at the time was an expensive dealer item. (Back in the 80's)

I would think that 3" exhaust would hurt more than help on a 4 cylinder. I could be wrong. Just throwing it out there.

Good luck with it. I hope it works out for you. Make sure to post up your results in case anyone else is looking to do the same.

 

Really? Well now that you mention that, it kind of makes sense. Similarly to the design of the 22r intake manifolds. Yeah they look restrictive but those engines had a problem with plenum velocity apparently so that why the narrowed to ports of the intake to increase the plenum velocity.

Ill have to find my receipt and see what size he put on (this was over 10 years ago so my memory is a little fuzzy). Hopefully I am wrong about the exhaust size, but I do know that it is a dynomax.
