I have a damaged but unopened engine in my garage and soon I will remove my current engine (water seal damage) so I will have 2 spare engines.

What would you suggest; should I pull these engines apart and clean all parts and store them like that or not make a mess and touch the engines until I need them? I don't want to end up with a jigsaw puzzle in my garage.

But asking this because I am not sure if useable parts would get rusty (or how fast) and becoming useless. Having said that it may already be too late as one of the engines have already been sitting in my garage for a year and the one with water seal damage has been in the car and sitting in my garage for at least 3-4 months.

 

Pull them apart, Label everything, and make sure you clean and thoroghly clean everything. That way when the time comes... everything is ready to go. You may even be able to put together a spare motor and have it built in the spare time. That way if anything happens you'll have a ready to go donor

what engine do you plan to put in the car?
honestly, if you have a third engine I would part out and sell these two
but you being in istanbul, not sure what the used parts market is like there
unless you plan to learn to rebuild engines yourself - its not really worth learning if you only plan to do it once

 

Frankenstein all the best condition parts together, keep spares. but thats just me as im cheap, and love hoarding.

 

^^ This was the initial idea but I have also been dreaming about a 3 rotor, not sure if I need 12a for that though. Another idea would be to own a track/show FC with a bridgeported 13b. Of course these are only dreams at this stage. I have to get my FD back on the road first. Your build thread is an inspiration btw

I bought a brand new engine so now I have 3 engines 4 turbos and 2 gearboxes There is no market here, I own the only original FD3S in the country, there are 2 others but one has 2jz other is a repaired wreckage. Most buyers would be from US and Australia and maybe some from Greece but the parts are too big and heavy so shipping would be the deal breaker.

My main concern is parts getting rusty because I'm pretty sure at least one of the engines have good condition housings and rotors.

 

Part them and hit them with wd40 and bag the parts to kkeep them from rusting... and it let's you see what parts are good

 

Just get some big plastic containers that seal good (finally a use for the wifes tupperware) coat them in oil like mentioned, wrap them in some nice oily rags, and store the parts away.

I'd recommend keeping the spare parts. With an rx7 you will need them.

 

maybe i'm odd but i usually just dump some oil into a core motor, run it around a bit and leave it alone. i hate having tons of random crap lying around also, i got enough of that already.

 

Yeah if you have room it's not so bad, just hard if you need to move stuff around. Them short blocks are hard to move by yourself

Also if the OP has never done a rebuild it's a great time to become very familiar with the engine. that's how I learned, bought a couple used engines and had at it. It's a lot less stressful when you're not learning on a working car

 

If you have the time take it apart. Usually coolant is noncorrosive, so just wipe the parts down and put some oil or grease on any exposed metal and try to keep away from humidity. Eccentric shafts are cheap (i put a brand new rx8 shaft in my FD for <$200). The rotors placement can be swapped during a rebuild, so you don't need to know which goes in the front housing and which one goes in the rear housing. The rotors, front counter weight, and rear counter weight/or flywheel need to be kept together as they are balanced to each other. If I was you I would build it up, slow and right, reading the factory service manual engine section several times. Then drive your car for decades!

 

Thanks for all the advice guys. Coolant may be non corrosive but I don't think I had any coolant in the system because the water seal was damaged so I had to keep adding water.

 

distilled water is non corrosive..

 

I had to top up too many times so I used tap water but eitherway, i'll empty the motor and the cooling system as soon as i get a chance.
