hi i am new here

i successfully made some power out of the car...modifications ihivf30 turbo external wastegate mounted on stock manifoldfmic with ss pipings3 cat back avcrsafcstock injectorsstock mafstock ecu stock clutch

i tuned the car on 7 psi safe boost for some nice power ,becuz its a lightweight car

results were better thn a supra 2jz stock..but heard piston slap on number 3...

then opened the motor to findout it was a spun bearing..i had a spare block completely fine only oil pump was finished ...so i borrowed a piston and a bearing from it...i again start the new build ok f9 but after 100 kms same problems.......

i have left some spares such as3 pistons ok and 3 bearigs okand a crankshaft

All of those parts look good on paper, but what are you doing for an engine management system? Your engine could've failed again for a number of reasons, so I say build it right and repair or replace the parts that are suspect. The stock rods will support your power desires.

Have you checked oil pressure? Are you sure that the oil gallery going to the 3rd bearing is OK? Have you had the crank checked out, maybe the journal on the 3rd bearing is out of spec?
