Ok my question is will a 3.4 clutch fit on a 3.0 flywheel?
I have a 91 4runner that I picked up with the 3.4 swap already done. I started having some transmission issues and so first thing I did was change the clutch. Long story short it ended up being that I blew out the syncros in the trans so I got another one. Now that I put the new r150 in it is almost impossible to get into gear and reverse is impossible. Now when the pedal is fully engaged I can still feel the clutch grabbing. I am running the 3.0 throw out bearing as we'll and have replaced both the clutch master cylinder and slave cylinders. Anybody have any ideas? I'm about to throw the old clutch back in as it still had about 85-90% life on it.

 

Nope wont work
you either need a 3.0 throwout bearing, 3.4 clutch, 3.4 flywheel. or all 3.0 clutch stuff cant mix a 3.4 clutch with a 3.0 flywheel
pretty sure the 3.0 stuff is smaller and weaker
