I have an MR30 sedan and was wondering if there is a replacement diff that i can get to upgrade to an LSD? I have installed coil overs and adjustable shocks, the car looks great (its about 4, to 4.5 inches lower :wassup: ) and handles pretty well but without an LSD it tends to understeer slightly into the corner, become nutral through the apex and then lifts the inside rear wheel and spins it when accelerating out of the apex. An LSD would really give full driver controll of the under/oversteer and make the whole package come together. I dont really want to spend a fortune, so is there a factory LSD i can pick up cheap or will i need an aftermarket item? Any help would be great,

thanks,

chris

There is a factory R200 LSD (as fitted to the DR30), and you can also get factory R180 LSD's (from 910 Bluebird Turbo's) too.

Neither are cheap....

The 'easiest' option is to get a complete DR30 rear end - this will give you larger rear discs, a 3.9:1 R200 LSD & 1/2 shafts to suit.

Be prepared to spend $1500 to set yourself up.

OK, thanks for the info. If i can get my hands on a DR30 rear end how good are the LSD's? Are there any obvious problems etc. to look for when buying one? Thanks again,

chris

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
