Me and a buddy pulled the RB20 out of the wrecked car yesterday and today I cleaned it up and removed some caked on oil and all that stuff. My question is, now that the engine is out and before it goes into the new car, what should be done to it? Since everything done to the engine is 100x easier while its out, its important that I do it now. The engine was used for 2 years by me before the car was wrecked, it then sat under a tarp for 15 months until now. So what is the rundown as far as what I need to do?

I figured pulling the sparkplugs and replacing them would be a good idea as well as replacing the water pump. A buddy of mine said it would be a good idea to replace all of the gaskets, is this necessary?? I didnt have any issues with leaking fluids before.

Thanks guys

For some reason I was expecting to either be told to use the search function or read the stickies.. I read the sticky that goes through what you need to do before a swap, but I assumed my situation was a bit different because my engine came out of a car that i was using previous to the wreck. Was just wondering what you guys would do in this situation

"[C]ame out of a car", all RB's, at one point in time, were in a car. So your situation is NOT AT ALL different than a new swap. Read the stickies and you should be fine.

What maintenance stuff did you do when the motor went in 2 years ago?

Here's a few things you might want to think of doing:Leakdown testWater pumpTiming beltTiming belt tensioner, guideOil pumpHead gasket3 angle valve jobExhaust manifold gasket and studsNew belts, rubber hosesPressurize the manifold to test for any boost leaks (my old TB/TPS leaked)

Other than that, change the fluids, change the spark plugs, it should fire up if it was running good when parked.

Why the hell would I sell my engine? I came here asking what I should do as a next step, not because I want to get rid of my engine.

Three years ago a shop here in town put the engine in the car. I really dont know what kind of maintenance they did to the car before they put it in, they never told me. I should have asked, but back then I didnt think to. June of 2006 a girl pulled out infront of me and I T-boned her, the car sat for over a year and I just pulled the engine out and thats where I am at with the swap.

I was going under the assumption that most people get their engines straight from a japanese vehicle that may have been sitting in a junkyard for who knows how long. I took into consideration that I used my engine for 2 years before it was wrecked and then sat up, didnt know what the typical rundown on that kind of situation would be, thanks

I say this is a very good idea if your not in a rush to drive the car.I would have done alot more myself but b4 I put my motor in I did this.

-water pump-idler and tensioner-timing belt-rear main seal-machined the flywheel-new clutch-spark plugs-drained all the old oil out and changed the filter-all new vacum lines etc.-3 coolant flushes

and I'm pretty sure thats it.Ran absolutley flawless for a full year before the ecu went and I decided to fix the wiring mess and upgrade a few things.
