1990 T2 Body, Marvelspeed 20B.
Stock seats, stearing wheel and speedometer, tranny and rearend, headlights, carpet and sunroof.

Everything else is replaced, upgraded or customized somehow.

Located in Central Illinois. Should be roadworthy within 2 weeks.

 

The T-56 is very common, as it is the current stock transmission found in Camaros, Firebirds, Mustangs, Corvettes, and Vipers. I may just get one from the salvage yard so that I can at least put my car on a dyno and determine what gear sets would be best. It would kinda suck to pay a lot of money for a new transmission, only to learn that the ratios are wrong. I don't know what I'm going to do with the rear end, as it depends a lot on which transmission I use. However, I am going to try to retain an IRS if at all possible, and hopefully a stock TII rear will work. Yes, I will need a custom driveshaft (the stock FC shaft is a lousy design anyway). Some T-56 links:

That's the impression that I got, too. However, my engine is being built as a low-rpm engine with basically a stock redline, so it will have pretty much the same redline as the high-output V-8's that the T-56 was made for. You guys who are building high-rpm engines may want to look elsewhere for a transmission.

Thanks, I didn't know that there was a high-torque model. I found it now.

LOL, no, you have a lazy moderator who knows how to copy and paste from the text file that he has been maintaining on his mods for several years now.

The 20B Corvair idea sounds pretty cool, but you may want to price high-torque transaxles before you commit to that project. I'm not sure what will fit in your car, but here is a nice 560-600 lb-ft transaxle for only $29,000 USD.

Corvair engines are reverse rotation. V8 swappers flip the transmission around so the engine sits in the back seat but I'm told the transmissions are lucky to last 1000-2000 miles when run backwards like that.

Just a FYI...

 

reverse rotation? hmm i didnt know that. i bet those cars last forever down under...

mike

 

Um, the stock Corvairs had 80-180hp. I hardly think that you would be albe to use the stock transmission with a 20B, hence my note about transaxle prices.

Yeah, some aviation engines have "reverse" rotation, especially on helicopters. I guess this is where the Corvair engine drew its lineage. It certainly looks like a helicopter engine, anyway.

 

Don't some Honda engines run 'reverse' as well? It's odd to see the transaxle on the wrong side, not that I'd drive a Honda .

 

damn that sucks, no one from dallas or EVEN tx posted here, i'd love to go see one if it was near by

 

There are a few in Texas. Not everyone posts on the forum or pays attention to all the 20B posts.

San Antonio at least has 2 20B FD's in town. There may be more since Tito was working on a couple of new orders for the Petit cradle.

Derek and Tito (Alamo Rotary) have 20B FD's running in their cars right now. Tito has the stock twins and Derek has a T66 single. Both are engines so clean looking you could eat off of it.

hondas are actually wierd cars.

mike

 

Hondas are reverse rotation 'cos they're ***-backwards

 

All of em except the S2000.

 

Yep. It's a high reving, low torque... wait, isn't that like a stock NA rotary? Oh wait, the S2000 engine is full of parts that still go *** backwards (after they went *** forwards and stopped a couple of times here and there with a valve or two, and a spark or sumpin... hmm, itza miston potor ). My goodness, what was Honda thinking? Maybe they hired a dyslexic engineer? It's still a cool car I guess. I wouldn't want to try to stick a 20B in it though (or would I? No, no crossbreading for me... yet. No no! ?!).

The 20B powered Corvair would really be something else!

 

yes it would, i was thinking today to put my s4 t2 motor in the tr3 so i can
A) confuse the guys at the british car shows
B) confuse the guys at 7 stock
C) confuse the cops (they dont look at cute british cars)

1959 tr3a 20b????

 

Where: Westminster, MD

Mods: See www.cris.com/~Asam/20B.html

BTW, since I have four kids in college, it's for sale. $39,900, and I'll consider taking a trade-in.

 

I e-mailed Pineapple racing a while ago about some info ona few things, I.E. thier 4 rotor( i want it bad) and what the different types of ports are (But since i have learned the differences) can anyone help me on the 4 rotor costs ? since i have not gotten a return e-mail yet.

 

I believe that it is about $7500 (with your 13B core) for the 4 rotor from Pineapple...depending on options.

The cost of everything else is what is scary...and you will "definitely" be cutting into the firewall (according to Rob/Pineapple).

 

Oh, Satan, get thee behind me! I love the concept.

 

its one of those idea's thats better in concept, the tr3 suspension is bad with 100hp, 200 would be nuts. we are tossing around the idea of a super7/ 550 spyder/ some kinda custom hot rod thing to get a 13bt in a >1500lbs car.

mike

 

I assumed that the Triumph suspension would be completely replaced with a real one. Even with all the mods the SCCA would allow, the TR3a was an exercise in self-induced terror. I liked it.

Three years ago, at MADS, there was a Super 7 clone (Caterham?) with a 13BT in it. It was the first time out for the car, so there were some teething problems. However, when it ran, it ran away and hid from everybody else. I liked it.

When you say 550 Spyder, I assume you mean the Beck 550 Spyder. (http://www.kitcar.com/beck/home.html for those of you who haven't seen it.) I don't know anything about the Spyder, other than what's on the page. However, there was a Beck Lister (same page) in the 2000 One Lap of America. As soon as I saw it, I knew what my next 20B project would be...in my next lifetime. In the One Lap, it had a 550 hp Chevy small block and was crazy fast. "Crazy" is defined as "would spin the wheels in fifth gear when already doing over 100 mph". With an 1800 lb. weight and a full-boogie 20B, it would eat Hennesy Venoms and Renntech Mercedes for snacks.

 

yup, i was talking about the beck, those things are cool. im not looking for insane amounts of speed, i just want a lighter package than any mazda platform (my r100 is about 1800ish), or something really cool

Hey guys, how would I go about sourcing a 20B? Websites, phone #'s, etc.? Thanks.

 

Search!

You may also want to start sourcing psychiatrists, stock brokers, and machine shops while you are at it.

 

Psychiatrists! LOL!
Off topic, but if anyone knows this, it'll be you Evil Aviator - do you have any info or webpage about tri-turbo 20Bs?

 

OK, OK, no more shanghaiing this thread (including me). Start a new thread or use PM if you want to deviate from the thread subject.

Here are some 3-turbo 3-rotor links:
