i just need to know if i can put a 88 short block in my 87 and just put all the parts from my 87 on that block. im pretty sure its the same and the only thing i hear is you cant use the injecters from the 88. so will the 88 motor/tranny be ok to put in my 87? both n/a. ummm....i think thats all....let me know if you need more info or anything. thanks.

 

AFAIK, it should be OK. Are you going to keep the harness, and just reinstall the low imp injectors? Are you even sure the injectors are different? What's the build date on the 87?

 

short block is identical for 87 and 88

 

And 86? (future reference)

 

86,87,88 N/A blocks are all the same.
89,90,91 N/A blocks are all the same.
86,87,88 Turbo blocks are all the same.
89,90,91 Turbo blocks are all the same?

 

thanks... yea i was reading up on the 88 motor and i found out the the injecters on the 88 are a diff type so im going to keep the same wireing harness and everything and just put everything from the 87 on that 88 block...well as long as the compression is good on it. i gotta check that out on sat. so pretty much im going to rip everything off the 87 down to the block and put it all back on that 88 bare block. so besides the injectors is there anything else anyone can think of that i cant use...incase something else on the 87 isnt workin right?

 

It is the 87.5 and later that use the high impedence injectors

It switched halfway through the 87 model year.
