Gen II 3sge piston noise when cold

I have been lurking here a bit...
I have also searched for info at this site on the above noise, albeit unsuccessfully.
I have a gen II 3sge in an AE 101. (actually CDN AE102)
The pistons are very noisy when cold. This is noticed usually
for the first few minutes of driving when the accel is released.
What I was wondering is does anyone that has one of these motors have any similar experiences?
I have put about 4500 kms on this motor, nothing seems to have changed.
I do have another motor avail to buy, I wondered if I should do this while I have the chance.
I ran it on the dyno,
131 whp, 130 ftlbs Torque.
1/4 mile 16.321 @ about 85-86mph.
I have it running on a gen I ECU. JDM ecu's are difficult to get here.
I appreciate any thoughts on this,
Mike

Yes, I am in Canada, cold refers to 20-25 deg C in the morning.
I was wondering if the pistons are normally noisy in this motor?

The piston noise is just the internal combustion efforts not being completely muffled by the oil....solution run a thicker oil.....my 3SGTE gen ii does this also on 5W-40 synthetic oil....if you want run a 10 or 15W and that should get rid of it, I dont mind this because I don't drive it until its warm anyhow.

ae102_3sgte,
I'm from Malaysia & I'm using the 165ps ( from the Celica ST183)engine in my ST150 Corona. I do agree that's rather noisy in the mornings but I was thinking that it may be due to the valve train components i.e. the tappets instead of the pistons. I'm using Mobil 1(5W-50) but I'm not really bothered by it as I allow about 3-5 minutes of warming up before I drive it.
Greetings from Malaysia

i dont know much about that type of engine, but alot of toyota engines have forged pistons instead of the usual cast type, and due to characteristics of forged pistons they are very noisey at start up
