Everytime this comes up I have to remind teh person saying it...
The handling does NOT get sloppy. In fact, unless someone specifically redoes the suspension for drag racing, the handling stays the same as it was before the conversion.

Trust me, years of direct experience with this, both with my own V8 RX7, and with the large number of converted cars that now exists.

Hell, I should give it to ME for my birthday. I lost track of it after it was sold to a guy in Louisiana (I sold it in '98 to a guy in Chicago, who took it to college with him in Georgia, where he sold it to a kid who had it taken from him for speeding, where a guy from Louisiana bought it, put a hood scoop, drag radials, and nitrous on it, and said he'd never sell it.) If I found it, I'd try to get it back.

yep go with the FC t2 rx7, but keep the rotary, there are a lot of parts for those cars. and insane turbo upgrades. doing the engine swap most of the time jacks up the 50/50 weight distribution, keep the rotary.

One, upgraded turbo rotaries GENERALLy have a lifespan measured in weeks, especially if they are N/A rotaries with turbos added. And two, as I already SAID (and can prove), engine swaps do NOT negatively affect the balance. Most of the time, the balance is unchanged or even improved.

Let me put it to you this way: a STOCK RX7 turboII weighs 2800 lbs. MY V8 RX7, with no efforts to reduce weight, weighed in at 2720. Sicne the cars are the same from the firewall back, and the V8 one was lighter, which do YOU think was more "nose heavy?" 50/50 is a nice round number, but it isn't the best for handling. You want a bit more rearward static weight bias. My V8 RX8 had 49/51 f/r weight bias. Most V8 swaps end up the same.

Another thing you have to rememebr is there were various trim levels of the RX7, from the base, SE, GXL, GTU, turbo, and convertible, all of which had differnt equipment and differnt weigh balances (the overall weights ranged from 2600 lbs to 3000 lbs), so 50/50 was NOT what all of them had for weight balance in stock form anyhow. An SE or sport with no options (like no AC or sunroof) weighed less on the nose than a GXL or turbo.

I'm not saying people have to, or should, do a V8 swap in them. I just want people to STOP making uneducated claims about what the swap will do to the car. What it does to the car is make it faster and more reliable, for less money.

Before I got the deposit together and started the payments on my Z3, I had a Ford Fiesta RS turbo. This was a really quick car and a very nice car to pose in

Who in the hell is psycho enough to replace the RX-7's motor with anything other than a rotary engine. You should call the damn thing the X-7 now. Blasphemey and pure evil.

I like that commercial in England with that Sportka chopping that cat's head off with its sunroof. I about fell out of my chair when I saw that.

Actually thats a Ford engine, look at the location of the distributor. If it was a GM engine the distributor would be in back, Ford always places theirs in front on the carb. and not behind. Chrysler places their behind sometimes, but mostly in front of the carb, slanted upwards to the right.

Yeah, I noticed that. Didn't Ford have a 350 though? Or did they just have 351s? Well, regaurdless it looks too big to be a 302. 351 ChrisV?

Ahh, the typical rotard response. I've covered this (as have many others) on RX7 boards before (and here, too). Are you ready to read the novel?

it's not a f*cking religious object. It's a CAR. Mass produced product of commercialism.

I had had many roatary cars for years. R100, RX2, RX3s, and a few RX7s, as well as crewing for an RX2 rallye car, and an IMSA RS series RX3 (the team also campaigned a rotary powered formula car). I've rebuilt rotaries on my kitchen table... (which is fine when you're single...). Iv'e also had many 4cy,l, 6 cyl, and 8 cyl race cars. When my last RX7 died after a season of daily driving an d autocross, and it turned out (this was back in '93, remember) that it was going to cost way more than the car was worth to rebuild the engine to stock specs (and the car was worthless in non-running form), and they were still unreliable in modded form, I decided to do something completely unique.

I had the car sitting there with an empty engine compartment, and I had my brother's 302 being rebuilt on an engine stand to go into his '63 Mercury Comet S22. The RX7s engine bay was considerably larger than the Comet's (or any of my Mustangs), so I hung it in the RX7s engine bay. I was amazed at how much room there was, and how far back the engine sat behind the front axle centerline. There was also very little difference in overall scale weight of the two engines. (350 for the ready to run 13B and 400 for the Ford 302...). I figured teh engine setback would compensate for teh added weight (as would moving the battery to the rear well behind the passenger seat).

At the same time, my buddy decided to take teh built 302 from his drag car and put in a big block, so I had a relatively fresh race 302 available to me for half the cost of rebuilding the stock 145 hp rotary. Which meant that for the cost of a stock 145 hp rotary with very litle torque, I could have a barely heavier engine with almost 400 hp and almost 400 lb ft of torque. And it would be like building a modern Cobra Daytona, or low buck TVR.

After putting the engine in, I found that it did handle better (the weight was actually carried rearward), and it was extremely torquey. At any speed a squeeze of the throttle made it jump. And it had no problems coming out of high or low speed corners. Even with a full interior and DOT tires, it was within a second of a gutted, full race RX7 on slicks that also ran E mod nationally. For a street car, that was impressive.

I drove the car regularly for 5 years before selling it. When looked at as an inexpensive performance car, it was one of the better deals out there. An excellent marriage of an incredible chassis, beautiful body, and inexpensive, but powerful engine. I don't worship at the alter of any one engine, or any one kind of car. A V8 is NOT the only answer. It just happened to be the right answer for this particular project. Had the rotary never died, I'd never have built it.

People have this mistaken notion that just because the V8 came from a car like the Mustang or Camaro, it can only go in a straight line afterward. Didn't anyone learn the lessons of the original 289 Cobra, the Sunbeam Tiger, the TVR Griffith or any number of road racing sports cars with American V8s in them?

Yes, SOME people build V8 RX7 drag cars. I've seen them. And some people make absolute hack jobs out of their conversions. Seen them too. But it's a serious mistake to think that adding the V8 ONLY means that it's good for just straight lines.

Read ALL of this thread, especially my comments:

http://www.teamfc3s.org/forum/showth...pagenu mber=6

Go to the http://v8rx7.com/ site for specifics on the conversion and how to make it work. Also check out Grassroots Motorsports Magazine's site. There are a number of guys there that have built V8 RX7s for road race and autocross use (since apparently, according to a lot more people who have direct experience with them, like myself, they handle pretty damn good as V8 cars)

http://www.grmotorsports.com/board/index.php

Remember, an RX7 in the driveway with no engine in it is still an RX7, but a 13B in the garage with no car around it isn't an RX7.

It's also the car's chassis name (and if you'll recall, the original RX7 was the Savanna, the replacement for the Japanese market Savanna, which we also knew as the RX3). but the RX name was originally invented for the US market, not what the cars were originally called.

The RX2 was originally known as the Capella in Japan. The R100 was the Familia, and the car that started it all was the Cosmo, which was never called RX anything.

Mustang means wild horse. Was the car ever actually a wild horse?

If someone has an RX7 chassis for sale, with no engine in it, does he say that it's an RX7, or just some Mazda that used to have a rotary in it?
