R150F-1GRFE marriage.

After mesuring the R150F put on the V6 engine without the bell, the front of the of the A750F bell with the rear of the R150F were cuted and welded









I used a Hilux KUN 2.5L cluth flywheel. A spacer be putted on the center of the KUN clutch flywheel to fit on the cranshaft of the 1GRFE





The circumference was lowered to fit the of the ring gear automatic flexplate.



The center of the KUN Clutch flywheel was perfored to fit the bolts on the crankshaft.

The bolts used was from a 2RZFE clutch flywheel.



Now I can use a presure plate and a cluth disc from a Hilux KUN





Pilot bearing its from a 2RZFE crankshaft

I used the KUN clutch set, because its a comon replacement part in Chile.

Have you looked into having a billet steel or aluminum flywheel machined with only one flywheel bolt to crankshaft pattern? Only problem I see so far is I think that flywheel is going to crack between the 2 sets of holes eventually.

Awesome build. I loved my 1st gen 4runner, but got rid of it to get a 2nd gen with 4 doors.

Looks like plenty of meat between the holes. I don't think there will be an issue.

Some where i saw this scenario and the unused holes were filled by machined pins with a slight interference fit . Pins frozen and flywheel warmed up in the oven and they fit right in.

I think that the mecanical flywheel from and FJ cruiser would fit on the R150F.... but it not exist as a auto part replacement in Chile. I could have imported it from USA va amazon or Ebay and include the presure plate and disc. The problem on that is that take a month or more for the parts arrive to Chile.
The clutch its a "fuse", a normal spare to change, and I cant wait a month or more every time that I would need to change it. So the most important reason to make an hybrid flywheel was to have the KUN clucth spare on every corner store in Chile.
As you said, the holes are a concern, and I did not welded and filled it, only for fear of losing the balance of the flywheel..... but still a concern.
A friend of mine did the same solution on his Hilux without problem untill now... does not mean that is not a failure point

Having those extra holes there is probably like having someone in the back seat telling you how to drive, be careful don't beat on it to hard I think the main concern would be any nicks in the old holes to act as a stress riser .

I dont think you will have any issues with the extra hole.
