Whats the cost differance in g-force and other such units? I am ready to start this conversion but want to make sure on whats the best for me.

Judge Ito was selling his G-Force transmission awhile ago, I looked into buying it................ but it was $9,000 used.

wow. Thats more than I want to spend on my weekend warrior. I and when I get serious about racing I can see going that route. So I contacted Redneck and they had no clue about rotary's or if the imput shaft would work. Basically said we can not help you in that area. ?? I thought these guys did a few? Or was it other turbo cars you were speaking of?

Redneck doesn't do the rotaries. They just sell built C4's.

Carribean sells the rotary C4 conversion kits.

Picked up a auto bellhousing finally.

Does it matter which C4 I use, a pan mounted dip stick or pump mounted dip stick?

I would use the case dip stick rather than pan due the fact that the pan style case is the large bellhousing ford style and you will run into clearences problem with the starter which you alerady have with the small bellhousing case one which you have to do some trimming but not mutch , check out the pics I posted on this thread its the case dip stick style.

Thanks a bunch. I'm going to have someone local build the converter. The bungs on your converter, could you possibly measure how tall those are?

Is there anymore information they gave you about the converter?..... or did they just say it's a 6500 Converter? Anything about the bearing design, balloon plate, hardened splines, stator or sprag assembly?

Have you weighed yours?

Thanks dude!

FYI, for anyone interested.

I've found a converter race shop that has recommended doing the following. Doing it this way would allow direct mounting to your stock flexplate.

I would send them my stock 13B Torque Converter.

They would use the front half of the stock 13B converter.

They would install C4 guts and put the ass end of a C4 converter on.

Alright, www.dirtydogperformance.com

I just talked to him again, he's going to mail me a C4 hub so I can take measurements. Then, I'll send him the stock RX7 Converter so that he can build me a custom unit. It's going to be a light weight 9 inch 6500 converter.

He said it will be $500. :) Not bad, huh ;)


I'll make a new thread, showing how to re-drill the stock bellhousing ti fit with the C4 pump etc. etc.

9000 bucks! Does that come with a jar of vasoline and a corncob?

Ps. Auto's are for pussy's that can't shift. LOL

9,000 bucks? Where did you get that figure? :dunno:

I could shift if I wanted to, but I'd rather make back to back 9 sec passes with a beer in my right hand :icon_tup:

I just don't see a lot of top rotaries using auto's and I think it's because the rotary has a low torque high power band and does not work well with auto's. You see most of the rotaries using auto's are sitting at the lights for like 5 seconds trying to get the boost up- race is over by then. hehe. You're also adding quite a bit of weight and rotating mass.

oh yeah, his gforce was expensive....... way out of my league

check out the aussie guys and the ricans, those guys have good luck with autos....... its all in the converter selection

what's a little rotating mass if you've got consistancy? refer to erniet

Thats the hole concept of the rotary to c4 tranny converter , mine has the stock S5 AT converter with the c4 guts and c4 pump inout shaft .

I am not sure if you are familiar with Lowe Performance , but anyways He runs a AT Tranny and is in the 7's . In my book is all in having the right combo it's going to take alot of time to find out the right tire size along with the right gears to meet with your engine power band . I have yet to see anyone put a car together to run a specific time and done it the first time out , I take alot of effort and changes . I have been to quite alot of events and seen alot of highend $ car with High $ tranny's and still have hard time getting to shift and miss gears .

What car and Tranny combo you got ? Post up some pics of your setup maybe it might change my mind and go the other route:hahaha: , but for now I'm staying with the AT:lol:

Really? See, I thought you had a C4 converter with custom mounts :lol: :wallbash:

My bad !

Check out this C4 powered rotary

I will post this here also.. Thinking of a future project RX3. What do you think? Would be a drag car only. I can pick it up very cheap..??

nice car...

how cheap?

Shhhh..... have to decide (convince the wife) first... If she says NO WAY then I will post the price and location....

update, dirtydogperformance thinks they might be able to find a billet front cover. Will update when I hear back. Hub is orderded.

Nah have the samething you are having done , were is ultimatejay at so he can check out the vid's and let us know what he thinks about the 9's sec AT cars :lol:

I guess what we are doing is a proven fact it deffenetly WORK'S , I love the cocistency of the R100 9.60's all day into the night try that with a manual :wallbash: goodluck :icon_tup: .

I gave dirtydogperformance all my expected hp/torque figures. He recommended a 5500-6000 converter. Does that sound right to you guys?

He also said with the low torque (500rwtq), taking a few seconds to come up on the converter will mostly be something we'll have to live with. The TH400 Supra cars use nitrous just to get it up on the converter quick. This might be something that we'll have to do.

Exactly, those cars are just too consistant and ET very well. None of that 10.04 @ 150mph business :lol:

all those videos and not one can cut a good light, waiting for the converter to come up,, the 60 foot times look like shit too.. not good

Shhhhhhhhhhh viking , you dont want to stir up this manual tranny QUEENS ! Even though you are RIGHT :)

Oh you already did , Man look what you got started .

Dude what are you talking about ? At first you was aquiring info and supposely you had AT setup and now you are downing the AT . Make up your mind either put on your miny skirt or your shortshort one or the other :lol: .

Oh by the way the driver has alot to do with a good RT , I bet you can't cut a light better than the one of those sorry RT C4 cars !

nice little wheels up C4 launch

http://www.youtube.com/watch?v=WSdMG...eature=related

That was my main point. You can have the most consistant car on the track, but if you're late at the light because you have to wait for your converter to come up.... Goodbye. But if your not racing heads up, then maybe this setup will be just fine for you. I personally just like the challenge of shifting and going thru the gears.

yah, did you see the other car get a 2 second head start while he was waiting for the converter to come up? race lost

oh, shut the fuck up ........... as if you know something that we don't

how long was the light green before he left? waiting for the converter to come up, not good for competition my friends..

I'd like to see some videos of you going through gears. Let me know.

Neutral drop FTW!:rlaugh: :nono:

did you read what i posted? i never mentioned reaction time.. i stated that these auto cars have a piss poor launch, because they cant go when the light goes green because they have to go when the car is ready.. the first 1/2 of the track is the most important part of the race ..if you cant leave out of the gate then go home!!(this is very important in competition)
after watching thse videos im pulling out my c4 setup and selling it!
im getting a jerico

Good, as if we beleived you had a "c4 setup" installed in the first place.
