hey, my sis has an 89 240sx that she is going to give me in about a year.  i want to do s15 det swap and max out the t28.  right now i have a 93 sentra se-r, i could have also done a det swap in it, but they have bad problems with tranny cases cracking and 3rd gears snappin in half at or over about 250hp.  ive heard that 240's trannies are good for up to 400hp.

So, my question is, what are some problems that will be run into once the power is cranked up on an 89 240sx??  
note: my goal with this car would be app 300+ bhp

well if your swapping in the S15 engine you don't really have to worry about problems with the 89...    The only things you might want to do is inspect the drivetrain, and verify she is in good order, and you will need an LSD with 300 hp.  That was not available on the 89-90 models.

The only problem with S15 DETs that I have ever heard of is the 6-speed tranny.  Some say that it's kind of weak.  I don't know if that is just a problem with the tranny overall or if it is related to high-power applications.

I'm pretty sure they just mean for high power applications.  Like 350-up.  Not Quite as strong as the 5-speed on the older SR's and KA's
