|I'm speaking with Doug from Z Fever of Florida about buying a JDM motor and this response from him confused me:
5) actually, this is not a true statement. We often get JDM VG30DETT engines with right at 200psi of compression and 180-185 is common. If we re-test teh compression with a little oil in the cylinder it will be higher.
Sounds very shady as I thought the "perfect" compression for TTs was 174..should I pass up this motor or is there some truth to this?
