3sgte is a huge amount of work. we just did a gen2 into 86 with programable, front mount, puck clutch, 4 coil on plug ignition conversion. its was $8500, and that is a bullshit cheap non repeatable deal.
ra60s are the live axle version, theyre not that heavy. a gze would go ok... i would consider it though only if you could get an AA63 cross emeber (not going to happen).
we can sell you a 1 ggte/gze fitting kit for your ra60 pirce is $350. we did the 1ggte ra65 matty was talking about. requires a decenet amount of hammering back the fire wall. but gets the engine nice and far back and low.
i would put an sr in it. sue me.
p.s ra60s ARE worth bothering with. if i wasnt an 86er from way back i would definately consider one. theyre cheap, look good (better with the 65 front) stiffer than an 86, and probably better for high speed shit.
on the 60 even more so that the 65, all 86 mods will work pretty much work.
its t series so lsd is easy. axles are way more common than t18...
DO IT.
