Don't laugh.
i am pretty sure i have changed my engine swap plans from the VG34 build to just put a VH45DE in my truck. the cost will be about the same, the work will be about the same, i will have a reliable 300HP, and it is possible to bolt to my transmission with a slight modification/ machining.
basically you use the front half of a Z32 transmission bellhousing, send it to Mazworx ( http://www.mazworx.com/index.php?l=prod ... ail&p=2770 ), who machines it and gives you an adapter to bolt the VG transmission to the VH engine. the Z32 front half of the housing bolts to the back half of my tranny, essentially making it a bolt on.
looking for a Q45 now...
everything i have is for sale now. will make a FS thread. ok lets hear some comments! lol
