dont want to switch out the trans, who is running the most power through their N/A reliably?

 

I will give you a few examples. I have 151rwhp with my n/a and my trans is taking a **** on me for the second time. I believe Kevin Landers use to have a 88 vert with a stock t2 engine with n/a trans in it and he lost fifth gear one day when he was driving on the highway. So my answer would be not too much more than the stock n/a puts out, any more power it won't last long unless you really baby the car, but what fun is that. There is no doubt that the trans is the weak point in the n/a drivetrain.

 

What exactly are you doing? Turbo swapping? If that's the case, you have a choice. Replace the transmission with the much stronger TII trans now, or replace it with one after the NA transmission dies on you while you're out driving. It will work with the NA trans, but the question is really how long will it last? As mentioned already, a number of people have found that it doesn't last all that long when you start putting 2-3x the torque through it.

 

Two years and 400HP didn't damage my NA transmission until I was at the 1/4 mile on a very cool night and hooked up rather well. Now it whines, but still works fine.

 

I am really rough with mine sometimes. Stock t2 engine na d-train all the way back.

It will be 2 years this may.

flip a quarter and your n/a transmission might not even handle stock output when abused. reliably? with about 40 less horsepower than stock.

they're crap, even though some people have abused them that is no gauge on how well it might work out for you.

 

Might get lucky, might get know.

 

I Dont plan on dragging it, just some AutoX, so I guess I'll stick with the NA trans till I find the weak spot and then change it all out then.

 

Look at it this way, NA transmissions are dirt cheap, and you can find them all over in decent shape. So even if your tranny does crap out, just throw another one in there. Even if you go through two transmissions, you'll still have spent less than buying a T2 transmission and either had a custom driveshaft welded up, or obtaining and installing a complete t2 rear-end.

I'd recommend keeping with the N/A unless you start blowing through them fast

 

Good logic there... last time I went to a rotory specific shop they had tons of transmissions lined up and he asked me a couple times if I wanted one for cheap.

 

they won't always be dirt cheap if people keep blowing them up needlessly, just saying.
