I am buying my 240 this weekend or next week most likely and am going to swap a RB20 into it. I have read up on Z32 brake upgrades and whatnot, but since the front clip comes with the brakes, axel, and hubs will they fit? This would save alot of extra money having to go to z32 hubs and brakes seperately.

I believe the calipers will fit, but the rotors will need to be redrilled. You'll also need conversion brake lines. I seriously doubt that the hubs will't fit if you planned on going 5-lug(even the 300zx front hubs don't fit). And there's no front axle just in case you didn't know.. ;)

Thanks for the info. Yea I don't know why i said axel haha.

Another good question is, Does anyone actually know the size of R32 GT-S brakes and if they are really much bigger than the stock 240 brakes, just to gauge if the conversion would actualy be worth it.

I think they're a little bit bigger than the 300zx iron calipers which are 30mm 4-piston. I think the gt-s brakes are 32mm 4-pistion.

I put 1990 Cefiro(RB20DET and 4 lug) brakes on my 1990 240 last weekend. Rotors are ~1" larger in diameter and the calipers are a bit bigger. Only issue was pushing the dust shield back a bit.

Skyline front hubs won't fit.They use wishbone as opposed to mcpherson struts.
