What's up guys . Got a sr20det built last year by a shop. Engine ran fan before stock but decided to build to get to 450 to 500 reliably with a gtx3076r . Did pistons, rods , new all ARP hardware. The whole 9. Tried to get it going last week with a tuner etc . Did the proper break in procedures and that crank wont really budge. Spins maybe a 1/4 turn by hand and then just stops. . Engine ran for 10 seconds and shut off. Drained the oil and no shavings . Undid the trans , starter etc and still hard to turn by hand with a 2 foot breaker bar. So yanked the engine out and having another shop take a look at what's wrong . Is it possible for that engine to be complete crap?
I'd appreciate any feed back or similar related issues.
