It has to be because of alot more than not using all mounting locations w/a drag car?.Seems to happen on alot of Dseries ef's ahhahaa and we all know that is no powerhouse!.But anyone who does not buy good mounts when doing a swap w/more than stock hp isn't too bright.We used Innovative 95a on the cr-x swap that was sold on here.The car came w/a nice torn up set of Yonaka's ahhahaa.But I guess you get what you pay for?.You buy quality parts and do everything correct it last and performs great.But if you buy cheap stuff and or install things rigged up you eventually will know what failure is.

Still this problem too me can not be so [common] a real common ef problem would be maybe the relay or something that happens alot! not twice.
