which 1 is easier ls swap or a gsr swap in a 90 crx?????

 

They would both be the same amount of difficulty.If you were todo an LS-VTEC swap you need a b18b block(LS)with a (GSR) b18chead which would take more work. Where as a gsr swap is just the b18c engine going in. But if your just talking astockLS andGSRpretty much the same except the LS doesn't have VTEC.

 

the ls swap would be easier. there is no re-wiring assuming you use an obd0 ls swap. the gsr swap would require a little bit of additional wiring, nothing dramatic though.
