4G64 con rod bolt torque

[moni]

Hi,
Am rebuilding the engine in my 2001 starwagon which is a 4g64 auto. The balance shaft bearing appears to have failed which has resulted in one of the big ends failing and ruining the crankshaft. Anyway had to get another bottom end which I am rebuilding. I have a workshop manual but the tension spec for the con rod cap bolts seems to high. After a bit of research I have discovered there is a six bolt and seven bolt block which have different crankshafts and rods and different size con rod bolts. 8mm for the 7 bolt engine and 9mm for the 6 bolt engine. My engine is a seven bolt which has the smaller 8mm con rod bolts. Can anyone tell me the correct torque spec for these bolts?

Should be the same as 2g 7 bolt 4G63/64.
14.5ft/lbs + 90° to 100°

o.k. Thanks for that. Was a bit concerned that tension would be a bit high. That is what my workshop manual says but could not work out if it was referring to 6 bolt or 7 bolt engine. The 6 bolt has 9mm con rod bolts and the 7 bolt has 8mm. Have seen other reference to a torque of 32 ft/lb.

For 6 bolt, it's 37-39 ft/lbs.

Interesting. So the 6 bolt with the 9mm bolts is about the same as 7 bolt with 8mm bolt. Did a trial torque on an old 7 bolt engine rod at 14 ft/lb plus 90 degrees. Used torque wrench to do the 90 degrees and went to about 38 ft/lb. Think I will just tension them to 32 ft/lb.
