Stiffen my 240's chassis

[240sx Fastback]

I am preparing my 1993 240sx Fastback for it's new motor. And for the amount of HP I wont to push which is 600HP to the wheels. I must first stiffen my chassis so it does not twist. I was wondering if anyone knew of any company that might make subframe connectors or do I have to do it myself. And how difficult is it to put a 300zx rear on my 240sx for possy rear with better traction?

If you are just wanting LSD, you can swap in just the pumpkin from a J30, canadian 240, or NA Z32. No need for the whole rear.

It's not only to get rid of the one wheel peel and get better traction it's also because I will need a stronger thicker axle to handle the HP and torque.

Stock 240 rearends and axles are pretty strong - it is the transmission you need to worry about.

NE way, there are tons of suspension and chasis parts out there. Start with Enjukuracing, Heavy throttle, PDM, and Phase2motortrend. If they don't have what you eed they can at least refer you to someone that does.

btw - what is your plan to putting down 600rwhp?

If you get any of those diffs mentioned above make sure it comes with axles. If you don't you'll have to buy z32 outdrives like me. took 1 month to get them. You'll need left and right and they are $220 each.

btw if your going to have that much h.p. your going to burn that clutch type vicous right up. You should just invest in a Quaife. Sure it costs $1200 but if you can break it, you get a new one. If you got money for 600h.p. I'm sure you can buy an almost bullet proof diff.
