I've officially become a "wanker"

[geeaj]

Just thought i'd share. I picked up a 89 rx7 turbo II. Now I have the best of both worlds, a s13, and a fc.

Observations...

The rx7 handles very nice, the factory limited slip and 50/50 weight distribution makes it a very forgiving car. More so then the s13. As for the wankel engine, its pretty #### quick, especially when the boost kicks in after 4000rpm.

So, I am gonna put around in my s13 until i get the FC running nice. Anyone else here own a 2nd gen FC?

[S13Grl]

How many miles on it? Has it been maintained properly? How does it pull? I raced one with my old S13 and didn't see much competition.

[geeaj]

89k miles. It actually runs pretty good considering the rear apex seal is leaking a bit, so I suspect its down on power a bit. My brother has a volvo c70  turbo and we did a little "race". I lost him by time i shifted to 3rd gear, we were doing about 75mph.

Nothing exciting until about 4000rpm and then it throws you into the back of the seat. I've been shifting at about 6700rpm and its smooth as #### in the upper rpm range. Once I get it tuned up, I am going to try to mash on it some more.

When I test drove it, I had it chirping all the way up to 3rd. But since its my car now, I am not gonna abuse it until I get everything running fine. From what I hear, new exhaust, downpipe, and CAI will yield about between 25-40rwhp. Then I get to play with boost and the intercooler. Yay!

a turbo rx7 should spank a 240.  you sure you didn't race a NA rx7?

[200sx]

Hey man, I saw a guy racing his 83 rx7 at a track ('king of the hill' thing... two cars, one lap... basicaly a drag)  He desroyed an 89 Mustang 5.0 that was built pretty good.  I talked to him after the race, and he said he shifs at about 9-10K rpm!!!!!   With the newer rotary, plus a turbo... you should  be able to do the same... or better!  Just got to have a good ignition system that will keep up at 10K rpm+.

[Takumi]

Better replace that leaking apex seal. That's the most common thing to go on RX-7's and it's the biggest weakpoint in the engine. Don't be surprised about the car's down time. My friend got a problem with his ignition sometimes after running it for a while. There's a leak in his fuel system or something that caused his spark plugs to get soaked and he'd have to wait a while before he could start up his car. I heard it's a pretty common problem. Other than that, it's an awesome car.

[geeaj]

I hear ya. Na, your friend needs to remove the sparkplugs, clean em, or even better replace them, and dis connect the fuel pump fuse.  Then, he needs to crank that son of a bitch until all of the gasoline gets pumped out by the rotors. Should be a 30min job at most. This is the common hot start problem with rx7s..

The 13B engine there is a problem with the injectors dripping after the engines been turned off,  which makes it easier to flood and thats where you get the problem with car not starting.  if this happens all you have to do is go to the fuse box on the driver side strut tower(its about 5" long) and take out the 2nd fuse from the left(INJ) and try to start the car.  That should get the excess fuel out of the system and just plug the fuse back in.  what my friend did here was go to the local autozone and bought a toggle switch and wired it to the fuse so he can turn the injectors on and off from inside the car(helps out alot when it rains outside).  Also, you can run the 13B 8000rpm and above without hurting the engine.  run can run those engines up to 10000rpm stock, but you'd have to either get a kouki AFM , go standalone, or carb(my choice).  If you have a over 140000 miles on the engine you're going to want to rebuild it because it need it , and while you have it out you might as well bridgeport it and rememdy the 6th port problem.

what's the scoop with r7's, what engine is in which model?  I like the one's that were around in 93, was it, anyway the last generation.  Is that an FD motor?  the ones before I think are kinda ugly.  No match for the stylings of the 93 240.

[wherezmytofu]

the none fd3 rx-7 has a engine mount kit the allows for a direct swap in of the 20b-rew engine...300hp!!!!...babi babi!

[Ni5mo180SX]

Congratulations.  Thats pretty sick. Im trying to get my hands on an FD right now. Too bad so many of them have crapped out motors due to negligent previous owners. Yea right, the TII would blow away a NA 240.

[S13Grl]

I didn't see a turbo badge, I didn't see a hood scoop, but he said he was turboed. I was pretty surprised myself, to be honest.

[Ni5mo180SX]

Yea I know the NA ones werent nearly as quick. The TII's usually compared to the S2000 back in the RX7 forums.

[Ni5mo180SX]

Nice kill though.  ;  )

[geeaj]

The n/a ones can be pretty quick. With I/H/E your pushing around 175 hp at the crank. Throw in a street port and your pushing 200hp easy. The 86-88 are actually faster because they are about 200lbs lighter then the 89-91 FC's.

N/A rx7 against s13/s14 with same mods would be a very close race. Its up to driver skill and the launch. However, if the race goes beyond 120mph, the rx7 should win because of the ability to rev.

[geeaj]

s13 girl..

If you didn't see the turbo hood, then most likely it wasn't a turbo. Although, if he said he put in a 13b turbo motor, its very easy.

My TII is running pretty good, I would estimate it does a flat 15sec quarter mile right now. Once I put I/downpipe/exhaust I should be making about 220hp at the crank.

Next, I'll start playing with the boost, but i gotta make sure the fuel system and ignition is up to spec. But overall, it runs pretty good. I raced my brother, he has a turbo'd Volvo c70 coupe and I spanked him once I hit 3rd gear.

My s13 sohc is still my daily driver tho, its so #### reliable!

[200sx]

Hee hee... I might not have the top end, but my 85 RX7 will destroy any other RX7 off the line. &nbsp;Put in a chev 350 V8. &nbsp;It is insane! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=':p'> &nbsp;(I bought the car with a blown rotary for $300) &nbsp;This little car will almost lift the front tires off the ground when I launch from a standing start. &nbsp;I can give a 5.0 stang a good run, but I run out of gears after about 120 MPH. &nbsp;gota get a 5 speed!

[silvia240]

i used to have a rx7 like &nbsp;years ago.. that is my favorite car of all time. &nbsp;I had a 88 nonturbo. &nbsp;I was fixing that car for a long time. It had problems like no other.... but after i fixed it it was perfect. &nbsp;That sucker was fast. I was pushing 198 hp at the wheels. &nbsp; I spanked many many cars. &nbsp;

[junia]

gotta give props to the rotary engines. &nbsp;same amount of power with about half the displacement.

[DuffMan]

Well actually rotaries displace their full displacement every turn of the crank, while a 4 stoke piston engine does it every 2 turns. So the a 13b rotary displaces as much air as a 2.6 liter engine at the same RPM.

If I ever go rotary I want to get a ported non-turbo 13B and put it in a FB and do some weight reduction. That way I'd have a fast cars without all the issues turbo rotaries have.

[PSI240SX]

I have allways said I would never own a rotary car simply because of reliability issues that I've seen. But if and when I sell my 240 I found an 87 Turbo II also. It's a friend of mines who's had it forever, it hasn't had a motor in years, just been sitting in his garage in pieces. He had it painted right before it blew up, 3rd gen silver, still no scratches or dings, and a lifetime warranty on it. It has 3rd gen wheels and brand new tires, all the a/c parts, factory interior and a set of 10th anniversary black leather seats and door panels. He told me I can have it for $500.00 &nbsp;Yup thats right $500.00
His motor is destroyed, and he sold the turbo, not sure on the manifold. Where can I get the motor/turbo complete? Also about how much are we talking to get it running?

[Tuck&Poke]

man those rotarys are amazing. &nbsp;they have fewer moving parts than piston engines (no valves etc.) &nbsp;and they make a crap load of power out of such small engine. &nbsp;for some reason though the seals on those cars suck ass so expect to replace a lot of em and have a lot of leaks. btw psi240 try getting a 3-rotor swap. &nbsp;mad power from them. &nbsp;they are the engines used in the cosmo over in japan. &nbsp;thats a very popular swap for rx-7s.

[MK]

Im sorta hesitant to believe the myth about seals going in rotorys, there was one owned by a friend who had an RX3 which was rallied pretty heavily (flogged like a red headed stepdaughter) and was constantly screaming its guts out through all kinds of abuse. Couldnt kill the bastard, for 2 years this thing had two speeds- redline and not moving. Just wouldnt stop and god knows he tried to kill it... probably still wandering out there as a class 2 rally car somewhere to this day!

Rotorys intrest me a lot, but I dont feel confident to work on them or even give someone a good breif on how they work. If the old SR20DET dies in mine I'll consider getting a 20B 3rotor twin turbo out of a late model mazda cosmo and sticking it it for shits and giggles. Lets face it, if it can drag one of those 1600kg luxo-barges from 0-100km/h in 6-7 seconds imagine what it could do to my 1100kg S13 silvia K's <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> hehe!!!

Yeap-
I've got two 10th Anniversaries putting out 400+ on the ground...Any tips you may need lemme know!

[redsuns3838]

no FC here, but im working on getting a FD. Only as a track car , and ill probably take it up on cruises in the mountains / PCH. but no way im daily driving those things. With their apex/coolant/oil seal issue i dont want to be putting high mileage on it.

MK- www.howstuffworks.com if you just want a overview of rotarys with a few diagrams.

PSI240SX- for a motor your best bet is going to rx7club.com and checking the vendors list.
a rebuilt motor and tranny can be pricey from what ive seen. but then im only interested in FDs .. you could go check out a junkyard, and grab a junked motor and tranny, and rebuild them yourself for somewhat cheaper though or even send the motor to be rebuilt. (much cheaper with a core than buying a new one)
