SR18DE Motor Siezed Up Week After Buying Car, Tips on Transplant

[bumdash]

Hi Everyone.

First car, a nice 1995 nissan pulsar GT sedan, week after perchase engine has SIEZED! unforseen problem that struck without warning just four weeks after an oil change and service. Just bad luck according to a DIFFERENT mechanic. Basically motor is rooted, of course, and am about to have it replaced. just wondering if there were any tips as to whether i should get another SR18DE motor or are there other options? also wondering if theres anything else i should get done while its at the mechanics for performance and reliability etc. car has done 144,000kms. Cheers
