Additional Torque Rod needed?

[Jdflyer]

Currently planning my swap and trying to work through all the details. I have a 1970 roadster and I'm looking at doing the S15 SR20DE (maybe DET) swap. It looks like part of the swap it is necessary to swap the rear end to the RX7, but I'm wondering if I will need to add a second Torque Rod to the axel also.

Thanks in advance for the feedback.

We have built a LOT of RX-7 axle conversions (for stock or conversion cars) and have never put an additional torque rod on any of them.

Just makes for building the exhaust even more difficult...

planning a boosted launch?

I think so much of what's 'needed' depends on what you intend to actually do with the car..

Couldn't agree more!

Thanks everyone. I appreciate the feedback.

I'm guessing for what I'm doing, 99% street, occasional track day, shows, taking my daughter for ice cream and scaring the bejesus out of my wife during semi aggressive acceleration I should be fine with only one torque rod.

Thanks again

Well, I would not want to drive an SR roadster without them, especially since it really is not very difficult to put it in..

But that's just me..

I'm not running any torque rod right now. I have an 8" Ford rear and SR20DET running 12 PSI boost. Everything seems to behave just fine at rolling start 1st gear full throttle stab. That being said I have not (nor plan on) doing any 6K clutch dumps.

Maybe there is something unusual about my RX7 axle swap but adding a second torque rod was necessary to avoid a sideways jerk when shifting hard on my SR20DET roadster. My mechanic used adjustable rods and they work very well. Yes it was difficult fitting everything together.

Anyone have a pic of a stock torque rod? I have no idea what it is or where it goes.

Thanks, now I get it!

I am rethinking my advice about the second torque rod. I posted before that the second adjustable torque rod seemed to be necessary because my rear end was doing all kinds of strange things on acceleration and when I hit bumps. The second strut helped but did not eliminate the problem. It turns out my drive shaft was too long and may have been causing all my problems. A shortened drive shaft was recently installed but the car is not drivable right now so no way to test. Give me a month. The measurements for the drive shaft were made when the axle and engine were newly installed and something must have shifted with use. The drive shaft was shortened by an inch. Error on the short side when dealing with a chassis that is not "settled". Other swaps have had this problem.

Don't forget, the early roadsters had none.

But the early Roadsters didn't have the power or torque of later models
