Dragger First Gen
Hey guys! As of this point in time I am enlisted in the UNited States army, but not for too long. I am looking to ge a first gen and drag it. the setup I wish to use is this...
48mm sidedrafts webers
bronze 4 puck
small street port
Turbo II tranny
GSL-SE rearend
as well as proper spark
the interior will be stripped, and a roll cage added. I dont like NOS (for cheaters I believe)
NOw my question is, well two actually....
1) Is this a valid setup
2) anyone run a similar setup and what times do you run
thanks guys!!!

If that's a 12A you're talking about, I wouldn't imagine you'd be running any better than mid-high 14's with that setup.
Just curious, but why the T2 tranny if you're just running a small port and weber?
IMHO, RX-7s don't make good drag cars. The car is built for road racing and cornering, not hooking up on a drag strip. Also the rotary makes no torque, especially if you start porting it.
My advice is to stuff in a streetported 13B 4 port motor, with a big *** carb like a 650 holley or equivalent. You could also do the T2 conversion, but then you're talking about fuel injection and turbos, which is a whole different ballpark. For good times and reliability at this point though, you'll need to beef up the rear end, somehow get some big rubber on there, etc, etc.
For all that cash, I'd build a crazy road racer, but that's me.

I'm considering doing a T2 trans upgrade. 180-200hp seems to be about the power handling limit of the stock trans when you start drag racing. You could probably get one to live OK if you're gentle on it, but with the low torque we have you CAN'T be gentle if you want to be fast.
Remember, we're talking about as much or more HP than a stock T2. Granted we don't have as much torque, which is a plus, but our launches are probably harsher because we need to rely on inertial mass because the engine doesn't have the torque.
Supposedly the Racing Beat Holley set-up is the best thing for power out there.... but the intake is so TALL... and the kit costs about $800. They will charge you $200 for "Race Float Bowls" that you can get from any speed shop for $40-50... so I wonder what's up with $800. I'm considering just getting the manifold and modifying it as necessary so a regular boinger-spec Holley will work properly.

The reason for the T2 tranny is I drive really hard. I broke my drive shaft in my 84 GSL, I crunched the rear end of my 88 and well i blew everything up in my Saab 9000, so I want a strong tranny.....

The set up you mentioned will be pretty good. just a few sugestions though.
BIG street port. If you want to race why would you even consider anything but the biggest port you can get? Even if you want to drive the car on the street you will have no problems. If this is a race only car go for a bridge port.
4.44 rear end. this will help you accelarate big time with out robbing too much top end.
The T2 tranny is a good idea. The stock tranny is Extremely weak.
You did not mention if you where using a 12a or 13b. let us kow.

I wouldnt worry about tubing and a ford 9" unless your planning on putting some serious power in there. Like over 250hp. The most you will be able to get out of your set up will be less than 200hp at the wheels. It will take a lot of work to get that.
If you really want to be fast your going to have to go turbo. You can do a turbo blow through kit with a carb on your 12a. It would be very trick and very fast. Also very hard to set up and and it won't make near as much power as a turbo 13b wich would be easier and cheaper to do.
