ok b4 u guys start asking why i would do this just hear me out.

i have a turbo d15b2 with dpfi to mpfi swap at 199k miles and its burning oil like ****,
i got a free d15b7 from a friend, gonna put that in so i have something to drive with to the street races hehe, but before i do is there a problem using the new motor with the old obdo engine harness?? The only thing i can think of is maybe the actuall connectors might not be the same type. eh anyone with experience

any help would be good even a yes or no will do...

 

if you're just swapping the motors i dont see a problem with the computers...

 

im confused here...what motor does a 1991 DX Hatchback 4spd have??.....D15B7 or D15B2?

 

a 4th gen dx hatchback's got a d15b2, but that's not a 4 spd. A 4spd hatchback is a Std model, and it has a d15b1

 

is the STD model a 16v ?

 

yeah i dont that exact changeover and i just used the mpfi intake manifold off the d15b2 and took the water sensor off the back of the B2 and put it on the back of the block on the b7, they're like a screw there in place of where the sensor should be, but u can use the water temp sensor on the b7 if u get the plugs for it. also u need the drivers side motor mount off the b2 and if you dont have a alternator for the b7 just use the crank pulley off the b2 and the alternator for the b2 to go with it. i think thats all. piece.

 

std is a 16 v
