I want to drop in a 20v silvertop or a redtop into my 1991 hatchback ae93 toyota corolla , what is involved in the process ? would i have to change the engine mounts or anything like that? will the 20v drop straight into my car? thanks for your timee

I bought a toyota corolla sx ae93 1991 model , and it crunches when i change from or to 2nd gear , It doesnt happen all the time but it happends often . what do you guys think could changing the gearbox solve the problem?
