the number refers to the size of the crown wheel (R200 crownwheel is 200mm in diameter) Its like when you hear people talk about 9" diff in their ford/holden etc. So from the outside the R180 housing looks smaller.

thanx.if i want to put on a lsd on my a31 rb20e auto,which lsd can easily bolt on only?can i use a abs type without changing the long shaft?

I think the ABS diff has a longer housing to fit the ABS sensor? Not sure though.

From what I see everyone uses R200 LSD. Make sure you get one with halfshafts to suit your driveshafts, skylines use 5*1 bolt pattern as opposed to S13/A31 using 3*2 bolts.

I have two diffs, both from cefiro's - both R200's one is a Viscous LSD with the Sensor plug, the other is a cusco 2 way LSD.

If you want an LSD you just change the whole diff, OR rip it out, strip it down and bolt the LSD centre to the crown wheel and reassemble. Be careful with torque settings on reassembly - you're best off getting a professional to rebuild it for you.

      Pete knows these cars well, he does my car too, if he was concerned about the traction arm length for your use he would have said so. Do you have adjustable bushes in that arm, maybe he got enough adjustment there (or maybe the bump steer was not material for your use of the car)

      Hmm. Yes. I should have been clearer. 1000s for Haltech, for extra headroom. 725s for Nistune. You might even be OK with 640s, but if the possible power ends up much more than 300 rwkW you will run out of headroom on the 640s. That would probably be OK and a signal to not push it to that sort of power with Nistune anyway. At that level you probably do want to be thinking about engine protection functions. Oh, and all of that presumes 98 only, not E85. Well....the 1000s would allow you to run E85 at ~300rwkW territory, again, maybe sort of running out of headroom. Hard to tell with E85 - depends on the tuner as to how rich they like to set it up.

      Yes.  The only scenario I can imagine when the answer isn't yes, is if you drive like there is highway patrol behind you at all times.  If your car currently runs, enjoy it and keep saving. Better costs more, keep saving until you can budget the better ECU. It's worth it.  Nope. Plenty of us making >300kw on unopened motors. Mine is unopened and makes about 350kw if I turn everything up, its fine (lots of caveats here, how the car will be used/abused, how long you expect the engine to last between rebuilds, how has the engine been maintained prior to coming into your ownership, etc etc).

      Sorry just wanting to clarify, at this power goal, which should I be going? Also, More info regarding suspension, the rear upper camber arms were used to get the camber back to i believe around -0.5 ~ -1 degree (@ Road and Race in Rydalmere), I forgot the exact figure, but ALOT less camber than what it came originally which was like -2.5degrees. Are the traction arms still recommended? The bilsteins from SydneyKid, they've got 400lb/in fronts & 275/in in the rear, revalved to his specs. Intercooler, I'm just having a look at some on Rakuten.jp and some other japanese sites. Might get something from back there, GReddy, Blitz or HPI, all crossflow. Looking at roughly $450-$500 AUD + shipping... Theres not many choices except that chinese branded Justjap unless you go for blitz return flow. Yeah, only downside with Haltech is the price ahhaha, so expensive, and with all the sensors if I go that route... $$$$$ yeesh. Are headstuds/gaskets needed for <300akw?
