Noob to Nissan, trying to idenitfy the engine. 91 SE-R.

[left footed whooten]

Inherited a free 91 SE-R. It has had an engine swap, necessary after a gas station failed to tighten the drain plug and ruined the original engine. I believe it now has a red top SR20DE, but the car is not in front of me, I haven't seen it in quite a while. Need to pick it up before snow hits.

Can someone delineate between the silver, black, and red top engines for me? I'm a Suby person, not very familiar with Nissan yet.

Also curious what people do about the popping out of fifth issue, seems common. What's the best fix? Rebuild? or is there some Nissan god uber fix that I don't know about. It sounds pretty bad.

Red top with no turbo? IIRC that's a JDM DE. A little more power than the US version.

I've seen kits for "curing" pop out. Many people just swap a later trans (95-98 SE-R or, preferably, 00-01 SE Performance Package).
