i need some info. on fitment with nissan chassis

[DDDsquad_s13panda]

ok well im a noob on this site and i've been looking around if theres any chassis to chassis fitment that might work out for the S13/SR motor from a different chassis of nissan/ infinity. e.g. the VLSD from the Q45 bolts right on the S13 chassis WITH the Q45 axle.

which might be a good idea if there isnt one. so please dont flame me if there is

well anyways. i have recently purchased a 1993 infinity Q45 from a neighbor for $500, and i was planning on going VIP with that car. But the mechanic that rebuild the motor from its recent blown head gasket was bootleg. He didnt even use a head gasket, he used the make-a-gasket glue type. And it looked like he just bought a bad water pump from a junkyard. So when i drove the car to san diego, in a 110 heat, the car went ballistic and the engine blew. rod knocking everywhere. And yes i did check the oil. and theres was atleast half in there.

So yeah. I have an infinity Q45 sitting on my driveway.

And i was wandering what parts i can canvas from it to fit my S13 coupe.
Q45 to S13 coupe SR20:
VLSD fit with the axle
90 mm throttle body. ( i have an SR also)
MAF air sensor.

and correct me if im wrong but i read somewhere i can also fit the fuel pump because the Q45 and the Z32 has the same one which can also fit the S13.

So please give me some advice on what may fit on my S13 coupe from the 1993 Q45.

if you help me.... YOU ROCK and ill buy you a soda when we meet eachother at a meet or event

thanks alot, i hope i get alot of response because im ready to send that spaceship to the junkyard.
