Where are you?

Where are you?
I'm not sure of all the things you will need? I would think you are going to need a repu oil pan,Front cover(repu or 12a),motormounts and more.If you are going to use the rx7 trans you will have to cut a hole about 6 inch back of stock.

on a budget here is what i would do....

you are already making it NON-Stock so go ahead and cut the hole in the floor it will allow you to easily use the Rx7 87 tranny, (i assume this is naturally aspirated engine with a turbo there are a bunch of ways you could go but infintely more expensive) we (atkins) have a webber wrapover manifold that when used with a 45 DCOE is making 184hp when using a 48 DCOE is making over 200hp. As for the ft cover and oil pan and such, they are right if you are putting this in a REPU..... however you are already going to have to make custom motor mounts so you might as well save costs and use the stock mounts from the 87, they mount in the center of the engine you will have to build your bracket to meet them. This way you do not have to change the ft cover and mess up the end play or even change the oil pan. You do need to ensure that you use and oil cooler in addtion to your radiator, i would either have one made or use one from an Rx7(possibly first gen) as the courier radiator is def not big enough. You will need to get a distributor from a 81-5 Rx7 with the black boxes(ignitors) on it as the crank angle sensor will not work without the computer and coils. Also do not forget that you will be needing to get an electric fuel pump as well.

In the other thread i did mention the superchargers they will bolt right on to this engine and have considerably more hp but they also cost alot more as well

"For what it's worth":

If anything from a yard is more than a core... evaluate it by how well you can make it run, and how badly it smokes, (and for how long), after startup. If you can't run it, odds are, it's a core at best. (You never know though, you *might* get lucky!) Can you turn it over by hand? Are the compression pulses more or less even on all sides of each rotor? (Feel 'em by hand after pulling leading plugs.) Look at what's in the cooling system, look at what's on the dipstick, look at the plugs--as well as the general condition of the heap, and the numbers on the odometer.
Personally, I have to be cheap, so I tend to think of non-running 'potential cores' as worth $50. Of course, it all depends...

i agree with Klaus wholeheartedly, if the car is straight why is it in a salvage yard, i have one yard in Texas that has 22 engines in the yard, and "all of them are good", "if you buy one and it is bad bring it back we replace".... yea right i have heard that one before, mean time i am out about 2 days cleaning and prepping and gaskets and such..... If you happen to find a wrecked one that could be an all together different animal then i would look at condition, milage etc.... for a good running motor i would not pay more than 350 unless it is a turbo, as for cores the only reason to buy one really is because you don't have one. Most salvage yard cores we go through at Atkins we throw away, how can we afford to keep buying them two word... quantity and luck (large quantites so we get them cheaper, also we take all of them not caring if they got pulled off the bottom of a lake and luck every now and then about 1 in 20 we find one that is absolutely beautiful.

I got lucky with the motor in my REPU. I got it pre-pulled from a yard $600 delivered to my door. It had 83k miles and they assured me that it ran. It did run and it runs pretty good I must say. Knowing what I know now about rotaries I dont know if I would be so trusting and go that route again. At the minimum I would check it out myself, pull the spark plugs and turn the motor by hand listening for even pulses. There is alot of work involved when installing a motor, do you want that all to go to waste when the "good" motor from the yard turns out to not be so good?
