well its time for a rebuild on my TII FB project. but now im not sure what to do.
i found an 87 S4 TII chassis that looks in better shape then my Fb.
if you look at my sig thers not much left to do to my FB or not much that i have not upgraded or changed. the Fb still has a solid body to work with just needs some minor body work that just started to rust through like the fenders.

this Fc i found only has 85000km on it. its has an LSD diff all power options. comes with 2 engines in precises and a rebuild kit some aviation 2mm apex seals, full 304 SS exhaust bran new, 5speed trany S4, new links and bearings. im thinking i could just take the best of all parts and dump them in the FC seeings as 85% of my Fb is FC parts any ways.

the real question i guess i have is what would be a better car for drag and road courses. im aiming more at road courses. in one since i think the FB is a lighter car but solid rear axle don't handle as good as the FC would i think.. i could be wrong tho.
any one have both cars and have a preference???

I like having a turbo-ed FB its somewhat different but body parts are hard to find as apposed to the FC.

Both cars do have their strengths and weaknesses but i dont personally think the FC is a better handling car than an FB if given the right suspension setup on an FB. Sure in stock form the FB is not amazing but it is a very good performer. But to this day with the proper setup the seemingly deminutive FB is still capable of taking on modern high performance. The FC may be a slightly bigger and more comfortable car but the FB has a certain fun to drive factor the I feel the FC lost. This along with the ability to make the FB capable of stomping Corvettes in autocross give it the upper hand in my books.

I however dont have both cars and but I have experienced the FB on the track and in daily driving. I say it does both fairly well.

I owned a few FB's. Some in better shape than others. Some with more power than others. But I'm on my 2nd FC now. I'll never go back. The FC has pampered me, and there;s much more aftermarket.

I've driven them all! Old School, SA, FB, FC, and FD. Out of all of them I still love my FC and probably will never get rid of it. It has a solid stable feel, while still feeling small and light. With an adjustable suspension setup you should do well at the strip and at the autocross. I've driven a few modded FB's with a lot of stuff done to them, and I think my low mileage all stock TII still handles better. It really all comes down to preference of what you want. Some people just love the look and the feel of the FB and they'll stick with it for life.

If the chassis is as good, as you say, go with the FC set-up, much better car for what you want to do. Only thing i would suggest is to ditch the aviation seals and go with OEM or some carbon 2mm seals...Good luck.

cool thanks for the input guys i did think i would go with OEM seals so FC3s i might take you up on that for a good price
i guess the next time i go see it il have to look at the car inch by inch. just o make sure shes as solid as i think it is.

Well with the FC you're starting with a far superior suspension, and a car that's quite a few years newer than the FB.

Then again, you've invested a lot of time into the FB which you'll have to start over with on the FC.

For road course use, an FC with basic upgrades will tear a new one into an FB with basic upgrades. Sorry, it's the truth. Just down to a newer and better chassis.

Carbon seals on a turbo car?

Pretty much agree with Mr. Cake's analysis. Including the carbon seals question - aren't they intended for extra-high rpm applications - like PP na engines?

I'd add that FC's aren't necessarily loads heavier than an FB - my 91 na FC weighs in at 2735lbs, and the S5s are supposed to be heavier than S4 cars. That's with no real weight reduction beyond an aluminum hood (not quite 15lbs lighter than the stock steel one), and I haven't carried the spare or factory jack in years - since, like the rest of my cars, I haven't made use of a spare in nearly 25 years, and so much of the time when I'm driving it, I'm on the way to or from autocross or track events, and have a floor jack and a complete set of rims and tires in the back. With my lighter BBS vert rims and r-comps, subtract 42lbs from that, and I'm below 2700lbs, in a car with a complete interior, 6 speaker stereo, and a/c. Turbos are of course heavier due to the turbo, associated plumbing and intercooler, and beefier transmission, diff, and prop shafts.

Sorry....should, i meant to say ceramic seals

I'd go with the FC. The improved suspension and turbo options make it much more competitive.

The 1991 Infini IV FC3S is one of my dream cars.
