I'm considering all the possibilities before I start buying all the parts needed for a t2 swap, and I just found out you can run a na rear end with a t2 motor and tranny with a mazdatrix drive shaft. Now what i am asking is that is it worth it? Will it break on me down the line? Or should I just keep waiting till I come across the t2 rear end components.

 

search. For the most part the n/a rear end is garbage when power is pushed through them, however a few guys have had luck with them.

What are you using the car for? If your going to be drifting or launching, get a turbo rear end.

 

I've been running a 87 non turbo car with a stock turboII engine/transmission with non turbo rear end for over five years with no problems. It's a daily driverr type car. Mazdatrix driveshaft.

I prefer that car to my stock 87 TurboII car.

 

There seems to be a lot of varied opinion on this, but ~300hp seems to be the point that the NA diff doesn't hold up well past - below that, you may get years of use out of it. Do you at least have an LSD diff? If not, I'd go looking for a TII diff and axles anyway, no point having power and using it to light up one tire at a time.

 

Well i tend to use it as a daily driver with some autocross fun. I dont plan on upgrading it any more after that. I just want to have a turbo, I dont think there is a point to have that much power since I wont be using it most of the time. also is this the drive shaft there talking about... http://www.mazdatrix.com/getprice.asp?partnum=2691-799

And I dont have a stock LSD, would that be something I should look into?

(and i did search, but I wanted someone's opinion on it.)

 

If you're autocrossing it, I'd say yes, get an LSD, S4 na or TII - even my NA with bolt-on mods is way too easy to light up the inside tire autocrossing.

 

So far 2.5 years with an NA LSD & a stock turbo @ 12 psi. Daily driven and occasionally launched when I get the urge.

 

awe but who doesn't love the one tire fire. =] i have it on my truck and my 7. it sucks havin that

 

yes, run the NA rear, IF it breaks than swap in the turbo diff. this is the easiest and simplest way. its a TON of work to change everything out just because it *might* break someday.
