S13, SR20det OR RB20det ?

[superduner]

Hey there guys i am a proud owner of a 91 S13 Hatchback LE with a Ka24de. And i recently went to a shop where they sold imported engines of all cars from Japan. So this guy told me i should either get an SRdet or an RB20det for it. Altough the RB was ALOT cheaper.. he told me that it made ALOT mroe Hp and Torque. if i remember correctly the SRs were going for $2,000 and the RB20det{s were going for $1,200. So im thinking.... the SRs are everywher eand parts would be more easyer to find since i really dot hear much of RBs... im thinkign if somethign broke down it would be a BIT.. to find the replacements part. as for the SR... i could get many parts that SRDEs have. (im guessing) so im guessing since im shuer theres guys out there alot alot more knowledgebla of what engine is better. What engine should i get. the SR or the RB .. and WHY? i mean.. am i right or wrong the parts for the RB would be alot more scarese and expensive. and is it true that the RB has more balls ? what would be the easyest inexpensive swap ? WHAT WOULD YOU GET ?
