I need to know if this engine (http://www.streetimports.com/product_details.asp?id=977) will fit in a 1988 Nissan 300ZX GS? Thanks for any help.

 

Physically it will fit.

 

your better off not trying to fit an engine in a car were it doesnt belong. you should research the Z31 VG30ET and i think you would like what you see. the Z31's came with an awesome powerplant. i suggest http://www.z31performance.com

 

dont listen to him i have a inline 6 twin turbo rb26dett swapped into my 98 240sx that originally came with 2.4l 4 cyl ka24de. it can be done but i dont know what engine mount , trans mount, driveshaft, custom down pipes, etc. just try all the z31 boards and im pretty sure someone on one of those boards would have an idea on what is needed to be done to swap the vg30dett. good luck and i say go for it.
