r32's came with the motors rb20det, rb26dett, rb20de and the rb25de. rb25de's are cheaps as chips, picked up a replacement motor for my blown r33 rb25de for $400, worked perfect ever since, guy even claimed it only had 67000 on it but i dont live in lala land and know that isnt true.
so if your smart and car work on cars yourself you can have a mad running r32 non tubro for around $500, which is wayyy cheaper than trying to fix up your unturboed rb25det-t.
