C4 auto to 13b rew quick question
 

Thinking of running a ford c4 auto in a gslse with a single turbo rew motor for drag racing. I think i need a 20b bell housing but not sure. I also have a gxl 2nd gen auto bellhousing i saved , will it work?

Thats what I am using on mine a 2nd gen bellhousing bolted to the c4 pump , you would need to tig weld the factory boltholes and redrill to match to the c4 tranny .

Here are a few pics also the web where I got my tranny combo from http://nctransmission.com/

you will have to grind the tranny case and pan to get the mazda starter to clear..
this is the same setup i have..
what size stall converter are you going to use? i chose a 10" with a 5,500 stall..
my car still isnt running so dont ask how it works , lol

[QUOTE=680RWHP12A;8088602]I don't have that problem with mine , I am using the 2 gen at starter the long skinny one . I went with the 10" also 6,500 stall 550hp to 850hp .

mine either its all in pieces over $9 grands everywhere LOL . This combo has been in the mid to low 8's so I assume its going to work !

here are a vid of c4 rotary powered .

Do you have a picture of your convertor/flex plate ? and the mounting holes from the bell housing to pump ?

looks awesome

if mine runs like that i will shoot myself!
it took 10 seconds just to come up on the converter= race lost

look at the second pic I posted thats the actual bellhousing bolted to the c4 front pump , I will take pics of the converter and flexplate . the engine that I have the tranny bolted to is just a dummy I am going to be using for building the chassis with .

Yeah tell me about it , I dont know what happen to him he stayed at the tree for a while but when he left it went and the best part did not even missed a gear . There a more vids out there of him and other with the c4 set up and they launch hard.

i know what happened, listen to the video, he was ready to go but his car wasnt!.. the motor struggled to come up on the converter, so he sat there and waited till it did come up.. he needs to loosen up the converter or add an 80 shot to get it up :)

I think it was a transbrake issue .I'm going to try on finding the other vids if I do will post them

Thanks for the post , I was trying to find it and no luck .

Thanks for the link and the info! That sounds great ,i have the 2nd gen bell housing ,my REW is an auto motor so it already has a balanced auto counterweight and flexplate.And i saved the auto starter, I also have a C4 that was built for a mustang that was never completed. being dontated by my retired old shool rotary drag racer mentor.He also said there was somebody here in Kansas within a hundred miles of me that is a nationally known custom stall converter builder,I have a streetported motor and leaning towards a gt 35r turbo with1600 injectors and a Microtech L10s. So i guess i have everything but the turbo, fuel upgrade ,and the stall converter.

that video was horrible, it took too long to stall then did a huge wheelie= lost the race twice as bad!!

im not sure about you ... your starter sits on the motor side, so the s4/s5 auto trany bellhousing is not the same......

[QUOTE=13BT_Starlet;8089396]Starlet, can you post a picture of you auto starter? 680 are you sure you are using the auto specific starter? I dont see a problem but i do not have the C4 here to mock it up for clearance.

ill take some pics later today and post them up.. its definatly an auto starter, it runs right into the pan/ case.. i clearenced the pan/case so it fits now..

Thats strange, i wonder why starlets fits with no problem? I hope to get over to where the c4 is today or tomorrow and test fit it. i will take the camera with me and get some shots.

680, who mounted your convertor to your flexplate ? Are you guys able to find decent deals on those convertors, I remember looking before and they were in the $750 range.

i mounted it :)
the converter is a custom unit,(8")it bolts directly to the mazda factory flex plate and there is a pilot that fits perfectly into the back of the e-shaft.. i got a smokin deal on my by a converter genious for $1,300

as far as price converters you get what you pay for, most top dogs are running niel chance or continental converters at around $2,000 a pop.. plan on pulling the converter out to get it set just right too... the niel chance units are a bolt together deal so you can adjust it yourself at the track if you really have to..
remember the converter will make or break your auto setup

not enough stall = too tight, the car will never get into the rpm's to get a good launch
too much stall=too loose, the car will blow through the converter, similar to a slipping clutch..

there are tons of adjustments to be made,stators,pumps,vein pitch,etc, etc..

Well, I meant……………… who fabbed the convertor to the flex plate. Not, who just screwed it to the flexplate. :)

why do I keep mispelling convertor ? what's wrong with me

Here are the pics of the starter bolted the bellhounsing and torque convertor
