$2500 for used engine installed? good/bad?
 
ok, got a friend who builds rx7's. He has a complete motor (turbos, alt, water pump...ect) with about 30k miles on it he said he would install it and sell me the motor for $2500. good deal? sounds like it to me.

Only if you get another 25,000mi+ out of it. and your looking for a cheap way to get your ride going again.

Motor and turbo's all stock?

AWD-RWD racer 09-09-06 09:11 AM

yes, its all stock, but I have aftermarket pieces currently on my motor, greddy elbow, 99 spec turbos, pullies, intakes, ect. so im not concerned with the stock pieces, I can just switchthem over, but to the best of my knowledge........it has stock ports. Besides, I think Im going to sell it after I fix it. im not a financally stable as i thought I would be, I have more important things to worry about than having to worry about my engine blowing up and having to fix it.

$2500 is pretty high, in my opinion, for a used motor install. But it is less than half of what you'd need to spend on a new engine and installation. And if you are seriously considering selling the car, then yeah....that isn't too bad of an option.

AWD-RWD racer 09-09-06 09:41 AM

the 2500 includes the motor and everything needed for install + install of the motor.

bajaman 09-09-06 09:46 AM

If you aren't mechanically inclined enough to change out the engine yourself (I mean no offense there....most people simply don't have the necessary experience) or if you don't have the tool or facilities to change out an engine, that pricing looks even better.

I've seen about 12 different posts on your engine troubles, and it seems that you are still grasping at straws a little....
Are you absolutely SURE of what you want to do? Can you afford to just sit back a few months and re-evaluate the situation? Do you have another car to drive while waiting on the RX-7 to be fixed?
Sometimes it is worthwhile to just sit back and assess your options.

IMO...do it right the first time because I might not have the fund for second round.

I look at this way:

1. Spend $2500.00 and take a 50/50 chance
2. Spend $5000.00 and have very low chance of future engine failure.

If I have took option 1 and engine later failed, of course I either sell the car or go for option 2. If so my cost will be $7500.00 instead of $5000.00 if go with option 2 first time.

i dont have the 5k do do it "right". I do not have the time to do an engine swap myself, not that I cant, just being that ive never done it on this car before I really dont want to go through the hassel and time of doing it myself. besides for a $700 install charge....it seems more than worth it. I currently have a 98 subaru impreza that im finishing up a tranny swap on. what a pain. I hate working on cars. (fixing) The guy that is installing and selling the engine is going to gaurentee it for some time. havnt gotten into the specifics yet, havnt had time to talk about it.

IMO, if you "know for sure" that you are going to sell the car, its a good deal to get the used motor/install plan.

However, if there is even a gleem that you "might" keep it, don't do the cheap route. Just let it sit until you can afford to fix it right.

I Agree Fully!

why would a 30k mile motor blow? just because it has 30k? is it possible to do a compression check with the motor out of the car, or does it have to be in a running vehicle?

You can check to see if it has compression at all just by cranking it by hand. However, you won't be able to crank it manually fast enough for about 250 rpms to do a real compression check (that and the engine should be warmed up for a proper test). ;)

just from my lack of knowlegde......could you use an impact gun to get it to spin fast enough?

That might get you closer but I doubt it is anywhere near 250. Also, Mahjik has already mentioned the fact that the engine must be warmed up in odrer to see the correct numbers.

pinkrx7 09-09-06 01:19 PM

you can connect everything on the ground [engine transmission and all to make it run]and screwdriver start the starter i think thats better than a impact wrench

Juan 09-09-06 06:08 PM

An impact wrench wont spin the engine at all. It will just hammer the nut its holding making it even tighter.

glad i asked

RotaryResurrection 09-10-06 04:47 PM

Most knowledgeable rotary shops charge AT LEAST 1000 for remove and reinstall of an engine, some upwards of 2 grand.

IN that light, 1500 for the longblock motor itself is a good deal if it has strong compression with no coolant leaks.

This is the plan, if you are just wanting to sell the car. Just dont start acting a fool when you get it back from the shop before selling it, or you could find yourself in the same situation again.
