some say its not, or it need to cut something in the chassis, i have 98 lx and i want b18c from a jdm integra

 

The amount of work it's going to take to get this done is crazy.
You will need to mod the frame.
Im pretty sure youll need to fab a mount or two.
The amount of wireing thats is going to be needed scares most people away.

There rumors of it being done by someone on here recently but he never came with solid proof.

 

Here is a link to a thread which should give you an idea as to just why its such a bad idea to attempt this. --> https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/honda-gsr-swap-getting-pita-2364737/

I've seen a fair number of these threads now, and I have yet to see 1 person actually complete one of these swaps and have everything work the way its supposed to. Usually the OP just disapears. However you want to look at it, it is infinitely easier and cheaper to convert to a manual.
