Hey guys, I just purchased a Fd and it needs a replaced engine and I would like to fix it up and sell it for a profit. I also know that v8s can be swapped in it. I was just wondering what would be more desired and what I could sell for more, a v8 or 13b. Thanks

 

V8 RX's are more reliable but price is relevant to what someone is willing to pay for the car. kelley blue book is a good resource for finding a base price for a stock car.

IMO V8 RX's are not any more valuable than a rotary powered RX but that is a very controversial issue in the rotary community and goes back to what someone is willing to pay for a piston powered 7.

 

dont be crazy. an fd is sought after (especially here in mn.) because its different. if they want a v8 they will get a mustang. dont ruin the chance you will find an enthusiast that loves the car! ROTARY AND ALL

 

Personally, I would pay more for it with a rotary and everything else as much stock as possible. The further away from stock, the less I would be willing to pay for it. However, that doesn't mean I wouldn't enjoy the V8.

When (notice I didn't say if) my engine goes, I will likely be going back with a V8. But I'm not looking to profit for it. I think I'll keep my project car for a while and maybe someday, it will really be something. For now, its no prom-queen. Its more like a junkyard dog. But will be running powerfully/safely here real soon.

Cars are rarely a good investment. Very little if any profit to be made. How many miles on the chasis can make all the difference whether the car is worth anything or not.

 

The car has 120k on the chasis and I bought the car for around $5,000. I'm also kinda scared to put in another rotary and have it blow within a year or two.

 

Consider parting it or selling the chassis. Added to the cost of parts, will also be labor, meaning its not really a smart investment.

 

The car is in excellent condition besides the fact that the apex seals are blown and I need to replace the enigne. Since I probably won make a profit I may just replace the rotary and keep the FD as my toy.

 

Ok here we go.

Ask the Piston FD guys and they will all tell you that yes it's less of a headache and damn they love the torque but in the end they still somewhere miss boost.

(Gonna get flamed for this one) Do a search for the essence video. If watching that video wakes somehting up inside of you you must go rotary power. If not Piston is the logical answer.

Lastly, if you have mad money and wanna go 3 rotor by all means do so.

Look for Rx-7 Specialties, Acosta Racing, Cam @ Pettit and @ many others.

On a final side not I am a pro Rotary so my decision may be biased. If i wanted an LS motor I would buy a Corvette!

With 400HP V8 you are not going miss boost you have power in .25 seconds. Besides you can supercharge or turbocharge V8 as well.

The V8 conversion isn't all that cheap though new subframe, trans and rear would all be needed.

 

Troll sheesh

 

i would personally take this time to get a 3 rotor 20B and pop that sukcer in, you are gonna need a new wngine anyways why not make it worth your while to dish out a tiny bit more, cause my theroy is ifyou are gonna fix it fix it right then only replace parts down the road that need to be, if anything i would stick with the rotary, cause it's stays true to the RX 7 name (notice the "R" in RX 7) or would you rather put a 350 in and call it a LX 7 ? your choice, my advice talk it with a grain of salt and everyone if happy

If it were and RX7 without a rotary I would not even have a look at it. I would just drop it as soon as they told me so.

As it has already been said 7s as sought after just because they are so unique.

 

After owning a rotary powered RX and currently having a v8 RX, I have to give it to the V8, no sh*t.

 

I'd be worried about a V8 being heavier and therefore affecting the balance of the car and reducing the handling - go the 13b...

 

if the original engine lasted 120k, unless your putting 60k a year on the car, it wont blow up in a year or two? 120k is about 10 years of driving for me...

 

no, you are wrong.

 

Go LS1 if you want a more reliable car. With boltons and a nice cam, you'll make over 400 rwhp on pump gas.

I don't have first hand experience yet with an ls1 powered fd, but I've read that handling is not at all affected with having an v8.

Check out torquecentral.com if you plan on going v8

 

Are you saying a V8 doesn't effect the weight distribution of the car?

 

There's at least 20 threads that cover this topic. Or for quick reference, you could check out http://www.hinsonsupercars.com/faq.htm. But at any rate, don't start making up bullsh*t if you don't know ;p

The turbo system for the FD also serves to add weight. The long block for a V8 setup and a 13B setup are close enough that you wouldn't notice the differences- if any, they will be negated by the better low end and overall power of the V8.

 

Bullshit. You obviously haven't talked to many (if any at all) V8-rx7 owners, and you definitely have never driven or probably even seen a decently done conversion. Do a little research before you try to pass off your own opinions as fact.

change the wankel for a ferrari modena engine or maby amg 7.3 engine .......... HAH AHah ha ha hA you asked for it

 

Well said saxyman, jbhaynes.

For the original poster - Your biggest concern should not be if it's rotary powered or not. It should be money. You're going to find plenty of people who think removing the rotary is sin - who cares. They're not going to buy it. Then, there are plenty of people who hate spending $3,000 to rebuild an engine because a $20 part failed. Those people will buy it. But in the end, chances are, you're not going to find someone who will spend more than about $17K for an RX-7...unless it has excellent paint, interior, etc...

How much have you spent on the car. Add about $5-7,000 for the conversion. Can you do it yourself? If not, add x $$ for the labor. Then add x $$ for profit.

In the end, there is only so much money you can get for a 10-13 yr. old car. If you want more than average, can you finance waiting a year for it to sell.

There is a guy trying to sell a V8 rx-7 for $40K right now. $40K! It's insane.

As for the V8 - I have been in one and driven one several times. If I had the extra money, I would have put one in mine. I couldn't tell a difference in the handling of the car - short of the extra torque.

good luck with the project.
