CAR ACCELERATES ON HALF THROTTLE ON WOT HESITATES N SLUGS .... ON IDLE THERES A CLUNKING SOUNDS COMING FROM NEAR THE TURBOS AND THE INTAKE MANIFOLD ...... ANY IDEA WHATS GOING ON HERE

 

Your question and description is tooooo vague. We need more details.

Thats like saying, "O doctor, i coughed today, whats wrong with me?"

 

well i just got the car a week ago it has a history of a weak secondary turbo .... the motor just recieved a fresh rebuild so far its got 300km's on the rebuild .... the car makes a clunking noise from near the turbos and intake manifold on idle the sound goes away once u rev it up to abt 2500 .... the cars smoking like a bitch its running way too rich ... its grey smoke evrywhere on startup ... the car accelerates fine on half throttle but once u go WOT on it it behaves very weird hesitates and slugs forward .....

 

I haven't broken in a motor myself, but going WOT on a motor with 200 miles on it is probably a Bad Idea. (every rebuilder has their recommended break-in procedure, but I'm pretty sure none of them recommend you doing WOT within 1000mi).

You may indeed have a shot secondary turbo causing the smoke. Blown turbos blow a load of smoke when you get on the throttle. To rebuild the engine and not at least consider installing a set of decent used turbos ($200-400) seems like a serious oversight if it was known the secondary could be going out.

What is your boost at? Do you have a boost gauge? If not, you really need one.
