Yea, rod bearing size is def something I want to get right no doubt. When I bought the 5E block it didn't come with any rod bearings, unfortunately. I would definitely like to get them measured, do you know anyone in Barbados who can take the measurements and recommend the bearing size?? Plan to make a few calls today.possibly bajan?!
i tend to stick to genuine toyota/OEM bearings and that's what i recommend.
regarding the size, you would need to measure up the crank using some professional (high quality) calipers or the plastigage approach.
if you are not sure how ti do it yourself or have the tools, i'd suggest you take it to a professional, its not something you want to get wrong at all.
the toyota/oem bearings have numbers/sizes stamped on them at the back of each bearing half (1, 2, 3), if you have not already disassembled the engine you can check those are you do---use them as a guide as you will still need to get the crank/bearing measured anyways to be on the safe side.
same procedure for the main bearings---toyota/oem come in 5 different sizes (1, 2, 3, 4, 5)
based on the forums, the other popular brands for bearings are ACL, king, taiho-----i can't speak to any of these as i've never used any.
500 whp? but how? lol jeez man id be happy with 300, def going oem. Will check out your build!!stock genuine Toyota bearings are best. i've just stripped my 5E for inspection after 2 race events/many tuning sessions at 500whp and the Toyota bearing were mint.
i'd try one of the credible machine shops with precision measuring instrumentsYea, rod bearing size is def something I want to get right no doubt.
