A friend of mine was also thinking about putting a TREMEC behind his turbo charged 3-rotor, but when he saw my set up and drove my car he did a complete 180. My 20B motor puts out about 900rwhp and I’ve been using an FB street/strip overdrive trans called the 4STB. The best decision I ever made! They have a total conversion package and I was able to easily install everything myself. I think its much stronger then any stick. So far I’ve gone 9.50s at 148mph in full street trim. You guys gotta take a look at what they’ve got for Rotary engines.

wow, nice find. too bad its not manual shift.

 

I really would like to see some t56 trannys behind the 20b. A good friend of mine is making 1100whp in his supercharged viper and hasnt had one problem. there is a differnence between the vette and viper versions though. apparently the tranny is a little clunky but its also supposed to be ridiculously tough. he street races the car and is an amazing track driver as well around the neighboring states as well.

 

a trained driver will surely aid in saving the transmission.

 

Hey rotary 3man what size convertor are you using with that transmission,if you dont mind me asking.

 

I assume from the comment that you have a stock trans. How much HP/torque are you running through it? I thought I've pampered my trans but still having trouble.

 

I was gona start puting in the same setup this evening and run in to this post,

is there a way to make the auto bell and starter work with the manual rear iron?

thnx

 

No, there are a few differences.

 

well I will pull the box out order the clutch and put it back togeather,
will put the t56 on the back burner until engine or trany brakes,

thnx IronMdnX

 

im going to have to bump this again, i want information on the bellhousing and adapter plate. by reading i gathered that the t56 is stock, with the bell housing and adapter plate being bolted to it. i had this idea when i was at school and the tranny we learned on was the t56.
if someone could pm me the info on bell housing and adapter plate.

Lloyd

 

nevermind, helps when i read.
auto bell housing, auto end plate, adapter plate that will need to be drilled and tapped, and the bellhousing shaved down .30"
am i missing anything?
and, by reading, since i am going to use a 13brew, i can use my stock style clutch and flywheel, as long as its 26spline? as well as the stock clutch hydros?

Lloyd

 

dont forget the driveshaft.

 

but besides that, i got everything?

Lloyd

 

tilton hydro throwout bearing

 

he did his way because he could, but there is this option of using the stock clutch with a 26spline clutch disk

Lloyd

 

Maybe Im misunderstanding do i need a different rear iron? is there a difference between the rear side housing?magus2222 mentioned needing an automatic end plate?

 

yes you will need a auto rear iron as the manual starter want fit because of the size of the gear box.

 

Well an auto rear iron shouldn't be a problem for a 20B lol....

 

im confused Im going to need to tear my whole motor apart and use a a different rear iron to use a different tranny? couldn't i just use an auto starter?

 

sorry for the misunderstanding. I didnt even know there was a difference between the auto manual motors as far as there rear side housings! learn something new everyday i suppose. but it does look like i dodged the bullet on this one since 20bs obviously use an automatic side housing since all cosmos where automatics to my knowledge.

 

so i need the cosmos auto bell housing or will the autmatic fd bell housing be fine?

 

I have an auto bell housing. Pm stevenoz...he has a few and wants half what others do

 

pm sent wating on a reply

 

good thread

 

i have an exedy twin carbon disk clutch for the fd is it possible to use this and just change out the center peice for one from the t56 or will i also need a different flywheel too?
