  1. Well, my hope was to keep my current z32 NA 5 bolt axles. Not touching the hubs, nor the axles. My intention was to swap the stub flanges on the diff itself; thereby creating an 3.5 r200v from a q45 that bolts into a z32 NA. Internet rumor says the Z32 NA stub flanges will pop into the Q diff (OH how much I hate the 8th party info out there!) Does this sound impossible? I'm not holding you to it ! one issue I have is that there are only a couple bone yards left that will let you in locally here. and BTW - thanks again.
  2. Yup - looks like you are pretty close there. I just dug up some Q45 FSMs on the web and the 90-96 is a 3.538, whereas the 97+ is 3.692. I'd rather find the earlier one if possible. Also, all reports seem to state that the in/out flanges will swap w/ the z32 r200v in/out flanges, meaning that it is quite possibly an easy all factory swap. . Good news all around. I'll try to locate one over the summer; can't rush these things Thanks a lot
  3. Yea- ya know... the 97 to 02 Q45 R200v is reportedly close to 3.5 and a 'bolt in' with the exception of the input flange. The tricky part is finding out if what I've read on the web is true! Of course you're right, unfortunately that translated to higher than desired revs on the highway. With the Nissan engine everything was fine but it just seems wasteful with the LSX since there is so much more there to take advantage of. It would be much better if first were somewhere between what is currently first and second. I'm running factory TT wheels all four corners, with the correct size 245/45/16 rubber. Thanks for mentioning that. I hadn't thought of adjusting things using wheel/tire size. Interesting. I appreciate your replies!
  4. Thanks...! The whole thing was (is) insanely tricky to do. Still plenty of bugs to work out; of major concern is making it handle more safely (tighten the suspension), and try to get out of the 4.08 rear diff blues. 1st gear is useless unless you're pulling stumps. I wish there were a straight answer out there for a bolt in ~3.50 diff, It seems that once I find an answer I find a conflicting answer somewhere else!
  5. Brand new member here. Hi! I'm just a hack that works on cell sites during the day and tries to balance the rest of my free time between family and hobbies. The hobbies mostly include trying to build and fix things. Anyway, after a long break from messing with cars, due to having small children, I figured I'd get another car four or five years ago. I found a 1990 300zx NA that needed body work, and engine work as it just simply ran like garbage.. After a winter of sanding and some injectors she went on the road. I got bored fast (as you probably are now ). Let's go turbo! I rebuilt my motor with TT pistons, injectors etc and prepared for boost. You know - I never rebuilt a motor before and I didn't think the VG was bad at all. The rebuild ran perfect, no turbos yet but ran great on 87 octane which was nice given the $4 gallon price at the time! One morning I was talking to a hot rod buddy and he said "why you gonna mess with all that turbo crap? just stick a V8 in there and be done with it". I once did a 260z with a ford 302 so it seemed do-able.... I said..."OK". sheesh.... ** Here we are so far - I took it for a blast yesterday and the thing goes down the road like it never did before... sorta scary for an old fart like me The thing works! ** This is the second LSX now. I started with a JY 4.8 that quickly spun a bearing. I obtained a tired 5.3 and did a simple rebuild with stock crank, rods, heads but with a ls2 cam, speed pro 4,8 flat top pistons and PAC 1218 springs. I am using the factory z32 NA 5spd. It sits fore/aft in the factory location. Driveshaft and shifter are untouched. I am using a -slightly modified steel SB chevy flywheel 153t (the smaller bore type chevy FW has the same center bore as the LSX FW by the way!) had to clearance bellhousing. -a 10.4" stock type chevy pressure plate. -a later model -ugh I forget- Japanese car clutch disk that had the same spline as the nissan 5spd input shaft, and measured 10.25". - a DIY adapter to mate the engine and nissan 5spd - a DIY pilot adapter - spaced nissan factory clutch fork/bearing - aluminum ford syyle narrow radiator angled like a z31, taurus fan, DIY shroud - DIY engine mounts - modified truck manifolds - microsquirt ECU speed density, batch fire - I am liking the simplicity of this! - Custom oil pan built from a truck pan * - factory fuel pump with S10 filter /reg * - edit: SBC mini starter with a remachined mounting base *next to come: accusump to increase oil capacity (4.5qts now), and bigger fuel pump. Also have to look at the bushings and suspension, it gets pretty crazy when you put the torque down. Just figured it might be of interest here, thanks for reading. I'll try to put a few pics up.....
