Hey guys i have an H23 turbo in my car and i was woundering what could be wrong with my car. See i have had two fullt built botton ends and they both spun the main bearings. The H23 blooks have bin both sleeved and balanced crank's with JE pistons and Crower rods.

 

Your going to have to give way more info, before everyone can make guess's..

Could be 100000 things with that info...
