Hey all, Im lookin for comments, opinions, suggestions and things of the like aboot my project car. I also posted this in the lounge, but I figure you guys who have done converstions before would apperciate this more, so...
First off its an Austin Mini (well it will look like one )
Second heres what it will have;
-full tube race chassis built to withstand 500-600hp
-either carbon fibre or fibre glass shell
-a fibre glass body kit w/ 5-6" over fenders
-M3 style mirrors
-Intake on roof above windshield for the kakpit (rally styles)
-Intakes for cooling both front and rear brakes
-Rotor shaped tail lights
-Adjustable (from inside the car) front spoiler
-Adjustable (from inside the car) rear spoiler, which when down is flush with the roof but has a small whale tail and when up is GT styles
-One of those rear valiances that curl up to create down force
-A functional Shaker hood scoop, but will provide air to cool the engine bay instead of feeding carbs
-215/50ZR15's on the front, and 225 or 235/50ZR15's on the rear
-Security system is: Windows that black out when car is off, no door handles, hidden electronic swipe or remote door opener, hidden start button (linked with the electronic door opener), and 4 motion senative digital cameras (one in each mirror, one on the roll bar facing forward, and one behind the rearview mirror... also will be used for racing)
-Front and rear disc brakes (vented, drilled, slotted, havent decided yet) with 4 piston calipers
-Havent decided on all engine conponents yet; Rebuilt and pp jspec engine, performance rad, intercooler, T-76, Haltech or Motec, fuel stuffs, etc. (nothing will be stock really...)
-T-56 6-speed transmission
-Custom straight piped exhaust 3 1/2-4" with rotor shaped tip?
-Racing seats w/ 4 point harness
and whatever else I missed...

Hows that look? Any suggestions, comments, opinions or whatever? My goal is to run around 500hp at full boost. Car will also be street legal and driven on the street on occation, as well as taken to the strip and track.
The way that the 13BT is designed, it will sit behind the front wheels in the engine bay therefore tecnically making the car a mid-rear car.
I put my order in for the chassis to be built the beginnin of next month.
I drew a pic of what it will look like after its finished if anyone is interested: https://www.rx7club.com/forum/showth...threadid=61266

Thanks guys!

ummm, wouldn't just the 13b engine and th t56 tranny together be longer than the car, much less if you stuck the engine behind the front wheels?? If not then how long a drive shaft would that have?

I dont really have a choice as to whether the engine goes infront or behind the front wheels, cause theres no room infront of the wheels! Yeah the engine and the T-56 will be long but it will fit and yes the drive shaft isnt going to be extremely long, 3... maybe 4 feet long. Id go with 3 over 4 tho.

yayarx7

Here are the dimentions.
13b=16",
T56=33",
9inch=12"pinion.
mini=80 inch wheelbase.
This leaves 19 inches for a driveshaft.
I do not know anything about driveshafts, but the front and rear yolk should take up about 10 inches or so, so that leaves you with 9 inches of tubing. I suppose that is doable but would check with a driveshaft builder.

Of course that would probably preclude you from putting in a IRS as all I have seen that can take that power have longer pinions than your ford 9inch.

Good luck and keep us posted with pics

Yeah your right aboot the whole 19inch thing, I dunno maybe it will work.
I was hoping to get a 6-speed transmission, but I dont HAVE to have one. After I start putting things together (before I get a transmission) I will decide, it will end up being the T-56, T-5, or the one out of a TII.

peejay

You wouldn't NEED a transmission - just direct connect the clutch to the rearend

Okay, you lost me on that one peejay!

yayarx7

the t56 appears to be the same size lengthwise as my 12a tranny sitting in the garage, so changing tranny's probably will not help much. maybe a transaxle?

I know a guy put the 13B in his mini (its a work in progress) and he used the 5-speed out of a second gen, so I dunno...
That would be cool if I could find an adaptor plate or kit to hook the 13B up to a transaxle, that way I could shove the engine in the back of the car!

http://www.phykell.freeserve.co.uk/Others.htm Thats the page with it on it, you can see how far the transmission goes back and how high up it is as well. How long is the T-56 in compairison to the FC 5-speed?
This guy on that page is kind of a putz if you ask me, cause as soon as he gets that thing together, the floor is gonna crumple! Ah well, I wont have that problem

rxrotary2_7

i think what he was trying to say was(trying to be funny)...b/c of the cars size, you may not need the trany?????? *chuckle* i guess..

Mr. ImportGuy

ok you want a full tube frame if you dont plan on building this its gonna be one of the more costly parts of your project if you want one made for you contact someone who builds GT-1 or TransAm frames they can put their TransAm frame in cad and drop the size like 60% lol then just have them anjust the roof suports of the cage to be a little taller and boxyer to fit the mini body you can either buy a glass body or make a mold from a normal mini then make one yourself and by the wide fenders or you could get someone who is racing a GT-5 mini to make you a mold of his car go to some SCCA races track down some guys with GT-5 mini's and talk to them I crew for a guy who runs a GT-1 camaro and all the guys love to talk about their cars go to some races get a paddock pass and go talk to people they will help with telling you of good shops in the area and if you can find a RW drive mini they will tell you how they did it this project is gonna be one hell of a project but its gonna be pretty cool if you get it done

http://www.mrmini.com/ <- thats the place Im gettin the chassis from
http://www.mrmini.com/racing.htm <- thats their race car

The guy seemed to know what he was talking aboot. I was there while he was building the "Cafe Racer" hehe (I still have yet to figure out that name) full tube chassis, s10 rear axel, chevy front spindles, a toyota corolla jspec engine turbocharged to 300hp...
The guy quoted me $3500 for the chassis set up for s10 rear axel and chevy front spindles. But I dunno if I want an s10 axel, how much can they withstand?
The only other mini shop around here is run out of someones barn... I guess I could go to one of those transam frame guys but I dont know where any are. Anyone else know?

yayarx7

there's a guy in GRM that has a rear engine rear wheel drive triumph? I think? 13b powered. So you could adapt it to a transaxle.

That's a pretty cool idea! Post some pics when you're finished.

Flamin' NOS

I've heard that you can use a VW Bus tranny and just fab a custom adapter plate for the 13b. Some guy on here did it on his car. Don't remember what it was, but it's been done.

yayarx7

You should be able to use the VW adaptor with a 914 transaxle to get a rear engine RWD car.

BTW the link you posted the mini in it has the motor intersecting the front track meaning it will have more room than yours, course the motor is further forward. Also meaning his will be less than ideal weight balance.

peejay

if you're talking about the rotary spitfire project, it is not rear-engined... it's front engined. (in fact the engine pic is in the Electromotive ads!)

Felix Wankel

If you use a 914 transaxle in a rear engine, rear drive car, you'll have 5 reverse and 1 forward gears. The 914 is mid engine, rear drive.

MazdaEbrahimi

don't know a whole lot about this, but how about a 924/944 transaxle?

yayarx7

I meant the mid engine rear drive as in a 914 as you correctly stated.

In the october 2001 GRM they have a 13b powered Fiat X1/9 with a transverly mounted motor and the Fiat tranaxle. bit of a codge job but it apears to work.

Does anyone have any pics of the rotary powered X1/9?

Jeff20B

iTrader: (13)

I looked for that issue of GRM but the book/magazine store was out. This was shortly after I first read this thread. Is there an archive or something?

I'd like to do a streetported 12A in an X1/9. Some pictures would be really great.

tarnell

I just did this in my rail buggy. You can get the adapter from Kennedy Engineered Products for $400-$500. I mounted a 12A to a VW transaxle. Not got it running yet but I'm close.

hootch52

I love the idea and am interested in what you have done so far. Any news? Let us know.
