I have a 2002 Maxima and I'm considering a custom turbo kit being made for it. Plan on getting some eagle rods and some upgraded pistons. I wanted to know if anyone in here has had any problems with snapping or breaking axles with all the power that boosted cars make? I plant on making about 420-440ft-lbs of torque....don't want to ruin those axles. Just trying to put the feelers out there. I called this place called raxle and they only make a heavy duty axle for driver side ONLY for my year. Then he recommended this place called driveshaft shop......they custom make axles but I know that is going to be hella expensive.....

I currently have Raxles on my car, both are clanking like hell (I gotta send them in for rebuild/replacement), but yes, OEM axles should be fine. Raxles are supposed to be factory replacement, just that alot of guys have had good experience with them so they use them for heavy abuse. I got about that same power to mine, probably why they are making noise.

Some guys here have done some pretty damn good 60' numbers on slicks and I have never heard of a snapped axle. You'll be fine. btw i have eagle and pistons too, at 15-20psi 3.5

Thanks for the response....

DAM!!! OK...I'm not going to boosting THAT much...probably like 10PSI maybe even 12 PSI. Right now I got a SPEC stage 2 clutch, which is an EXCELLENT daily driving clutch, says it will hold 390 ft-lbs...they have a stage 2+ that will hold 440ft-lbs, they say its just the same as the stage 2...but if I make more torque than that I have to go to stage 3 and I heard it was a little harsh on the engagement and I drive this car daily to work and back, grocery store, everywhere and I don't want to be annoyed with that harsh engagement! I think I will upgrade to stage 2+ and then leave it at that. I think you reach a point where you have too much power and the car is not streetable anymore because you have to add all this crap on to hold the power.

no reason to upgrade. i can think of any people that have broken axles due to too much torque. wheel hop maybe. you'll almost certainly break your trans before you break an axle.

This is my main concern too... the transmission acting like a fuse.
BTW, if this is you daily, dont put a Damocles sword over your head by boosting above 10psi on a stock engine.
With a good turbine choice, the VQ yell's good numbers at 8-9psi.

I been turboed for about 5 years now with no problems. Still oem axles. I am using a stage 3 clutch by Clutchmaster and its held up just fine and very streetable. But then again I`m a measly 389 torque. lol

like stated above the trans will break long before the axle, btw the only axle you have to worry about is the drivers side. For some reason the passanger axle never breaks

really? Why only the drivers side? If that is the case I spoke to this guy at Raxle axle and he said they offer a heavy duty axle for drivers side only. I will buy that then just for extra security. Im going to put pistons and rods in the engine and probably boost about 8-10 PSI but going to do meth. I dont want to go down to 8.5:1 CR because I dont want to lose any low end power just to gain more up top. I want to keep same CR. I seen some JE pistons at 10.5:1....I believe stock in the VQ35DE 2002 Maxima is 10.0:1....and stock 350zs are 10.3:1 and seen those turboed all day on stock motors no problem so I dont think that will hurt, especially with the meth I believe it will be fine.

MEASLY??? LOLOL!! Yeh right. If 389 is measly then my 250ft-lbs is terrible...lol.

Sorry, off topic. But you have a typo on your sig. says SC, supposed to be TC

Maybe he have the Vortech supercharger.....I don't know.

the only VQ35DE that is 10.0:1 is the pathfinder. all the rest are 10.3:1.

OK.....cool. Then even better a 0.2 increase in CR won't hurt

tbh i would want a weaker axle, i would rather break it then a transmission.

Isn't the tranny in the 5.5 gen max the same as the 350z tranny? I've seen 500-600hp 350zs on stock trannys no problem.

no, they aren't related in any way... how would you use an RWD trans in a FWD car lol
