Yea sounds like he's low on transmission fluid.

I got a 1987 supra 7mge + 5speed MT Not auto transmission so fluid won't affect power transmit

check the cat convertor...

I had a similar-ish problem. I re-zeroed out my timing and reset all the timing stuff. Cams to TDC and pully to zero. Make sure it is EXACTLY right, mine was only off by a notch and it gave me almost now power. Good Luck!:x:

Thanks , I will do it tommorw, I wish get some power!

the 3 holes on cam sprockets
 

there is a pin for the cam sprocket and camshaft to line up, the pin should go to the middle hole of the cam sprocket right?

Yes, you are correct.
