r31_skyline

hello all, I've got a R31 rb30 auto skyline ( ok, hold the applause LOL ). I'm just about to convert it to manual 5 speed. The next piece of the puzzle is the turbo setup. questions: 1. a stock reconditioned turbo setup including everything to suit a VL turbo i've priced at $1500, good deal? 2. The pinging and detonating problem? I've been told many theories on how to get around the pinging problem that will occur putting a turbo setup on a N/A motor. Some of them sound a lil dangerous and dodgey. theory 1: jump 1 tooth on the timing belt retarding it more than steady eddy! theory 2: ram the adjustment around on the distributor so far that u put the bold on the outside of the adjustment bracket - too yet again retard the timing to hell and back. theory 3: Use a spacer type head gasket to lower compression, retard the timing as far as the the distributor will allow you, then install a rising rate fuel pressure regulator. The first 2 theories sound very lame to me, theory 1 sounds like a bush mechanic solution. theory 3 sounds reasonable to me. and yes the $1500 does include the WORKS, including big injector, turbo computer and manifolds etc. The engine has 184k original on it so it should be rather low compression by now. Can somebody gimme some insight??? thanx all.

Yet another r31 question, The rb30det in stock form is supposed to put out 150kw at the flywheel stock. My R31 was originally auto and non turbo. With the rb30det and a 5 speed manual, will the borg warner auto diff put up with the punishent that the rb30det and 5 speed put out? And would anybody be able to tell me what the diff ratio for the auto and manual is ? I guess the speedo will be affected if a diff change is done?

Hi all, Just a few technical questions concerning gearboxes to fit rb30 motors. From what i can gather, r31 rb30 gearboxes are getting more and more expensive and harder to find. I have found that VL commodore boxes, ( called M7 's) will also fit ( using the VL's tailshaft ) to the skyline, but these boxes are even harder to find! The turbo VL box ( MX7 ) is impossible to find and usually retail around the $1000 mark. Long story short, I wanted to know if R32 or R33 boxes will fit onto my rb30 motor ( Like bolt in, perhaps a tailshaft change ). I have found that r32 and r33 boxes are MUCH easier to find, just wanted to know if they are an easy fit. Any help would be greatly appreciated.
