hey

i am planing to buy 7 soon so my brother was wondering can he put v8 in the FD. it looks small for v8 but a friend of mine says it is possible ( the 02 corvette engine). i like rotary and the only reason i would consider this is i want to build about 800 hp on the engine so i can make some money on the race track. my friend knows corvette engines pretty good so he said he would help me also get me a cheep one too.

BTW, I DONT WONNA KNOW HOW YOU FEEL ABOUT THIS PROJECT.

Thanks

Search for jimlab's thread "taking rotary blashpemy to the next level". It is about 20 pages long.

Nevermind, I did it for you.

well i know u dont care about thoughts but i think u just dont want the bad ones..hehe. anyways i think this is a great and original idea to put a new vette engine in. i think it will be awesome and i love rotarys but this sounds great and will definately eliminate some of the reliabilty problems. :1party:

$$$$$$$$$$$$!!!

Paying all those G's for this project will probably be equivalent to 2 motors and 2 turbo sets...which will probably last you 160,000-230,000 miles on the rotary. 160,000 miles is atleast 12 years driven. You make the call

refa

i can get the parts cheeper then others. and i got a friend that has a good experience in the vette engines
i will do all the hand work my brother will help me too
so that should lower the cost
i know it will cost but the reliability and power of the v8 would make up for the 2 rotories and 2 turbos
expecialy if i put the nos in it and the economy is not bad at all for the v8 19-28 mpg

i think you need to get off the REFA!



what do you mean SupraJoe

REFA, you know. Wacky tobaccy. Grass. Puff the magic dragon. He's suggesting you've been hitting the peace pipe.

Hey Joe, did they swipe your old account or are you just looking for an image change?

GsrSol

Anything is possible if you got the money money mooneeeey.

I don't think it would be a good idea because seriously, it doesn't sound like you know what you're getting into or talking about. Not many cars can have 800hp and still be reliable.

DAMN nice...sumthin about ur post. its alllll true too

suprfast

im sorry, i just cant stand the fact that people want to buy one of the best cars in the world and put a POS motor in it. granted the rx7 motor isnt the most efficient(reliably) doesnt mean to put a different motor in it. i think if you want a V8 buy a CRAPSTANG. if you are going to swap get the 20B. i also think that the supra motor in the car was gay as hell. if you dont like it, dont buy it.

man_of_steel

hell, let him do it if he has the time and money. Good luck, too, honestly. That is a major undertaking. I'd rather do a 20b, but thats me. And Jimlab can say whatever the hell he wants to, but I stand by my decision. Anyway, I hope it turns out to make a badass FD, if not, for much less $$$, I will say "thbbbbbt" as you stare at my taillights...but seriously, if you are completely intent about doing this, good luck with your project.

You never learn, do you. No matter how many times I tell you, you never retain a shred of information concerning Bill Hagen's car. Let's do this one more time...

1. Bone stock Camaro 275 hp LT1, not an LS1
2. Full emissions equipment
3. Stock cast iron exhaust manifolds
4. All accessories
5. Added 100 lbs. of ballast to the car, weighing in at ~3,000 lbs.
6. First time at the track with the car.
7. FIRST TIME AT THE TRACK WITH THE CAR.
8. DID YOU HEAR ME??? HIS FIRST ATTEMPT AT DRAG RACING THE CAR. What did you expect. 9s???!?
7. His swap cost about $5,200
8. Great platform for mods. $2k more spent in the right places would put him at ~380-400 RWHP.
9. 18-26 mpg
10. Much stronger transmission with 6-speeds
11. Never have to worry about apex seals ever again
12. His trap speed indicates that he's got a potential high-12 second car, as-is
13. Stock FDs run, on average, about 0.6 seconds and 5-6 mph slower...

hmm that should keep JoeD in his place.

Yea I've thought about this quite a bit lately since my motor is blown. But I'm going to give the rotary a couple of more tries before I just simplify it jimlab style.

I've thought about a conversion (seriously) for about a week now.

I've been through rebuilding 13B's several times for my FC (modded heavily with E6K) and FD (single w/ lame G-force ECU).
I also had considered the 20B since it would cost me about $8K to do it myself. I had the 20B front end lined up for me to purchase. However, the bump steer frightens me.
About Petit's 20B car, they don't use the engine cradle that they sell for the FD. They did it right by pulling in the driveshaft so that the 20B is not pushed forward (causing a modification to the steering rack).

About the comment with 2 motors and 2 turbos:
You're not guaranteed 160k miles. The previous owner went through 4 engines trying to get his FD into 11's (11.4). You have a higher probability of getting more life in a V8 than a rotary engine.
About every FC/FD owner that has modified their car (to any degree) has had at least 1 rebuild.

Furthermore, my friend (race shop owner for Mustangs: www.prewittracing.com) has a very reliable 800rwhp Mustang. It's driven on the streets (when the cops are away). It has been getting 9's consistently for about 3 years now. He has another all motor mustang that runs high 9's consitently too. Yet, I believe there are not MANY reliable high horsepower cars out there.

Finally, the originator never asked for your opinions.

It's lame to search for good information on this forum when everybody puts their opinions in it and most probably haven't even done their own engine work.
As much as I like the rotary engine (probably stemming from my engineering background), I'm rather sick of rebuilding my engines. At least when you rebulid a piston engine, you can spank on it almost immediately. With a rotary, it's the 600 miles before any boost and then some more TLC.

Good luck to your project, refa. I wish I had a hook up on the '02 Vette engines.

Thanks for the information, Jim.

for who? I put 35k on my car in 2 years, so


35000/160,000 = about 8 years for me

With the cost of all those motors and turbo sets you put down you still wouldn't be over 400rwhp+. It would take a couple more grand to go single and get that 400rwhp+. It would take much less to get a LSI, LT1 with 400rwhp+ in there.


Compare the 2:

Rotary: You said 2 motors w/2 turbo sets = probably about 9k.. Providing you then spend 500-1k on ecu, 1k+ on intercooler, 1k on exhaust, 300 on intake and then whatever else you need. You are at around 12k for 375 rwhp, Then add on what's need to get 400rwhp. Single turbo, fuel, etc. You are roughly around 16k right there.

Chevy v8: 1 v8(esp. LS1 or LT1) you can get power out of easy, much more forgiving when leaned out, and you have loads of torque, that v8 grumble. You may eventually at say 100k-150k end up needing some motor work if you are hard on it, or if it's just a higher milage motor, but sometimes if you are easy on it most of the parts can be reused. You don't have to buy a new block like you would rotor housings. And this isn't a have to because I have seen stock v8's last way past the 230k mark. And you can do it for way under 16k..

Yeah, I read all of that thing. Pretty interesting.

Okay guys.....
.
.

to finish this once and for all....

an FD should have a rotary engine. That is the main "draw" of the car. Mazda Was praised for putting the rotary in a production car. An LT-1/LS-1 is an American Non-rotary engine. To add that much weight, you would lose the perfect 50/50 weight distribution in the car (which makes it handle so well)....

.
.

Stop whining. If you want an lt-1, spend $5,000 on a complete Z-28.... It's cheaper than a swap......

Rjuge:
You obviously didnt spend any time to read jim's post. Weight can be kept 50/50. And as for the rotary being the main draw for the FD, for some people it's just the look of the car that they like.
