I have NEVER seen pictures of a TII with a factory automatic transmission. You?

 

If all FC's in Japan came with turbo's....just what exactly do you expect an auto to have in Japan? It's not rocket science, but perhaps you could use some scratch paper to do some calculations on?

 

find me pictures of a TII automatic. better yet, find me a TII 3.90 gearset. that is what the original point was about in the first place.


get back to me when you find that gearset. until then i will be waiting with my scratch paper, smart ***.

 

i hope this helps you, i never finished reading the entire thread

That is a good thread. There is a lot of good information in there. I do think that the T56 is more than this guy would need though. I can tell you from first hand experience that the T56 is a bit clunkier as far as shifting goes than any Japanese manual transmission I have ever used. It is capable of handling a decent bit of power though so that plays a role.


IIRC The f body T56 has a .75 5th gear overdrive and a .5 6th gear overdrive.


Once you got into 6th the car would proably stop pulling anyway.

 

Then you haven't looked hard enough. I got an S4 T2 front clip from Japan.

Also to the kid who started this thread. Didn't Dave's unfortunate death teach you anything. By the way I checked out your "mods" list at the begining at the thread and your smoking crack if you think your car has enough to truly smoke a 911. Maybe in your dillusions you saw yourself kicking his ***, but from his vantage he wasn't even trying to race you. He probably barey even noticed the kid in the smelly, loud, and and most likely beat-up porsche 944 looking car driving like a fool while sipping his latte. I like how you only cruise at late night....not. The only other cars on the road at that time are drunk drivers and cops. Real smart man...not. Sorry to be a dick everyone, but this thread is rediculous and needs to be sent to the "kills section" with the rest of the morons. Dude before your next high speed run why don't you go and talk to the girl Dave had a head-on and gain some wisdom.

the clip was factory automatic. Sorry

 

ok well I guess this was a bad Idea......I wasnt really gonna do it but, It was just a thought. I'm just gonna go back to a-spec. Icemark, or whoever send this thread to downtown!

 

[/QUOTE][QUOTE]You cant hit 200 in this car. First of all its gear limited. You would need a custom rear end. Secind it takes a butt load of power and good aerodynamics to hit 200. The C6 Z06 is only good to 198 mph and its rated at 505 hp. Most people are dynoing mid 400's at the wheels, so its certainly underrated. 200mph+ is almost an unpassable number on a street driven car.[QUOTE]

? wouldnt mid 400's (450) at the wheels be 500 at the -eShaft
? Wouldnt "good aerodynamics" for 200 mean a .31 cd? .31 is closer to the reg vetts cd then the zo6 34?
im just thinkin outloud

 

custom rear end? What about a motor that makes power at 8750 rpm .
is that possible

 

god, nobody reads the whole thread anymore, look, he wants his car to be around 2k at 60-75 mph thats it, and he said 17year old CAR not his age.
damn.

 

can we please just say "3.90 gears, different final drive in tranny, or power in high rpms" and call this thread slaughtered?

 

I highly doubt there was a 1000rpm difference between the same speeds. That would be a serious gearing difference.

 

Remember kiddies the stock speed o isn't accurate at those kinds of speeds. 172 on the gauge may have been 155.

 

Rumored? All FC's in Japan were turbo'd, and somewhere between a quarter and a third of were automatic. They used the same 4.1:1 diff as the manuals.

You've never seen a picture so it can't be true right?

 

some-one said you people need to slow down..i hear that..people in the NE region threads no what happened to me..in my 87 gxl i was doing 45mph,and some ***=hole in a lexus pulled out in front of mel, and i hit him it was his fault..and my car crumbled they had to cut me out..now i got 2 broken ankles and i cant walk..theirs no reason to do over a 100mph..unless your at the track..later

 

Here is the thread:

I may be in line for this if I can get the dog ring conversion.

 

Get the TII to NA driveshaft and you can use a 3.90 NA rear end in your TII.

 

This thread is amusing.

If the J-spec TII trans has too short of a final drive ratio go the the A-spec trans. S5 TII has slightly taller 5th than S4 TII.

If you do the calculation based on actual ratios and tire diameter a S4 TII is doing 178mph at 7,800 rpm fuel cut.

It is no problem to hit that w/ stock turbo and lots of boost creep as boost creep gives you more HP and torque the higher the rpm.

Dead stock the S4 TIIs did over 150mph. FC was designed in the windtunnel and has better aerodynamics than most cars past/present including the FD.

In 1985 RB did 238 mph w/ *just* 500 hp in an all stock body class TII.

It doesn't take much straight road to top out a modded S4 TII. W/ ~400 hp 1 mile will do it.

It will quickly toast your trans rear seal and you risk getting trans oil on you hot exhaust. The only fix I have heard of is to weld material on the tail housing, bore and install a needle bearing and new seal w/ a modified driveshaft yolk.

Or replace a lot of rear seals and risk fire.

Don't attempt this when there is another living person in harms reach!

 

Thread cleand up as much as it can be. Please keep it clean. There is no excuse for some of the posts here by members who should know better...

 

if you have a TII making big power and a broad powerband, you'd want LESS gears, not more!

I'd be happy with a 4spd in my car, and to be able to trap in 3rd in the 1/4 and have much taller 1st.

 

The J-spec has a lower 5th gear.

Crack it open and put a US-spec 5th gear in it.

Problem solved. (You'd do good to replace the syncros while you're at it)

*pointed out the obvious*

 

The Auto FD has 3.9 gears in it, perhaps you could get some of those?

 

wow Did anyone see that sidewinder missle?! Oh nevermind.

 

Thank you!

You've made every point I was about to, and then some. Glad I read the whole thread before I posted...
