Although readings do vary a bit between compression test gauges and depending on the exact procedure used for the compression test, (fwiw) I've never seen (only) 100psi in any 2jz-gte that is "fine". In other words, I agree with Suprra_girl & MrNickleye that the internals of this 2jz-gte need further inspection, and likely some (or a lot of) work+parts. |
Hey great link. Yeah from the TSRM itself compression should read at 1079kpa/156psi and at least 128psi the difference between each cylinder should be around 14psi. So in essence there is a serious problem with the motor. Going on what t88widebody has told us and the diagnostic readings we have so far I would recommend a complete tear down and place some forged goodies in your motor.
Now of course the 2jz blocks are strong to begin with but like every motor it has its limit. 1400cc injectors with a T88 turbo is obviously pushing it. Also we dont know what type of engine management you are using but if its not adequate then that could mean problems as well. Now imho I would tear it down and do a complete engine rebuild with forged goodies to prevent that from happeneing again. Oh and if you are running that much boost and fuel I would highly recommend getting a standalone or at least the emanage.
