i was racing a turbo eclipse and after i beat him i noticed that my car was no longer runnin on all 4 sounds like 3 werid thing is tho is that it dosent smoke or anything and i had to limp it home 20 miles and it was still runnin the same when i got home...it does have forged pistons...time for a leakdown test...what do u guys think it most likley is...oh the engine is basicly a mini H23 its a B20a from an old school prelude..the engine still has like 19 in. of vacuum at idle also which i thought was strange... also didnt feel hear or notice anything funny while racing the lipse we were doing close to 115-120mph i dont have a FM system just the SAFC 2 stepcolder plugs 450cc injectors and a walbro pump T3T4 turbo timing is at 9 degress BTDC (Base) who knows how much it will advance oh and im on 12psi..thanks

 

Do a compression test, and/or a leakdown-test. This will show busted ringlands/headgasket/valve leak; it's a great tool for diagnosing compression-related problems with the engine.

 

ya i know that but i was just wondering if anyone had an educated guess

 

plug wire came off? plug broke?

 

no i cked that i looked at the plugs they all look ok except number 1 but even that plug dosent look bad...i dunno i went to go get a leakdown tester and couldnt find one at sears...guess i will have to wait until i get back to work to buy one off the tool truck...damit

 

make sure one of your injector plugs didn't come loose (are you running clips to hold them on?)
...dont ask how i know


good luck

 

nah im pretty sure i got something pretty wrong...i cked number 1 cylinder compression it was 60psi so its either a valve or the pistons...my luck its the pistons...guess im gonna have to rebuild it again this is the 3rd motor... not gonna turbo it again with out standalone....i want the EMS
