Picked up this non-running '73 240Z in Wisconsin, it came with an R200 (which I had planned to use, but am now going Ford IRS 8.8) and a mess of other stock parts.  It looked to be perfect for what I was building and after media blast it's quite solid other than floorboards so here we go. 

 

Parts already here

-LS3 TR6060 dropout from a 2010 Camaro w/ 30k miles (lookup Midway Mustang Dewitt IA)

-CXRacing LS swap kit w/ headers and y pipe

-CXRacing Front LCAs and TC rods

-CXRacing adjustable coilovers

-T3 Rear LCAs

-Silvermine billet front 5 lug hubs

-Silvermine front wilwood brake kit

-Zedd FIndings Floorboards

 

Parts to order

-T3 rear backing plates

-T3 rear strut tubes

-Ford Explorer 8.8 Diff

-Z32 rear 5 lug hubs and brakes

-Wheels/Tires, S71B ~17x11 (5.5 backspace) and 17x9.5 (4.9 backspace).  315/35R17, 275/40R17

-Flares (TBD, maybe SSWorxs???)

 

My rear end will largely be based on Sunny Z's build.  Digging through the wheel forums it looks like 5.5" backspace on the rear is doable, any advice here on whether 5.5 is too much?  The T3 plates should put the wheel in the stock location.

What's your opinion on the CXR fronts LCA's and TC rods? I brought those up awhile back based on price, never saw them in person, but they were generally shot down as "Chinese junk" by most of the community....... To be honest, I've been very happy with my CX LS swap kit, but will admit it has no critical moving parts to fail under load. Looking forward to your build. Thanks, Jim

I guess I don't see a big difference in the design of the LCA and TC rods, others seemed quick to dismiss the CX stuff tho...whatever.  

 

Update on build - floors are out and 1 of the 1x3 subframe connectors is in.  Also ordered a set of WELD S71B wheels in "low pad height", which should clear the wilwood front and stock Z32 rear brake calipers.

The Z32 TT brakes and hubs showed up.  Unfortunately RockAuto lists Raybestos 711011 (Timken 511011) as a TT hub/bearing assembly, it definitely is not.  The axle flange wouldn't fit into the bearing.  Did some research/measuring and turns out I'm not the first to find this out.  RockAuto told me multiple times "the part is listed correctly" and wanted nothing to do with fixing the real issue.  The TT hubs are harder to find and more expensive.  Ended up going with Z1 motorsports for the 46mm I.D. hubs.

Lots of parts going together.  Floors and connectors are done, Sparco R100s mounted, front suspension has been mocked up and the wheels clear.  Not sure my rear wheels will ever show, so I went ahead and ordered some 15x10 Aeros and Mickey Thompson 26x12x10's.  Hopefully it will be off to get a roll cage soon.

I'm thinking of going LS3 for my Z as well. Also thought about utilizing the the spare tire well as a fuel cell holder, but I want a cell big enough where I can hop in the car and drive 3-4 hours without worrying about a fill up. 

 

How big is the cell you put in? Can't tell by the lettering.

Thanks. Probably too small for me so I may still mount a larger cell in the stock tank location. 

 

I have a few other questions since I haven't started ordering parts yet - still stripping my Z down to send it out for sand blasting and primer. 

 

For the trans..are you having to custom fabricate a trans mount by hacking up the original one? Or is there a bolt-in mount? 

 

I was thinking of going with the bougie LS3/T56 combo but I wasn't sure what trans mount options were available - if any.

Making progress, I was in CA for all of June, so that slowed me down a bit.  The engine/trans/diff are in and mounted.  I was able to mock the headers up with the engine in.  I was only able to thread 7 out of 8 bracket-to-diff mounting bolts.  Zcardepot said they had never seen this before, we settled on a $100 refund. 

 

Driveshaft and CV axles are on order from Driveshaft Shop, now it's on to wiring and getting fuel to this thing!

Well it runs and drives!  I was covered in media material after the first drive, but well worth it.  Doing a 4 wheel alignment in the garage this week and plan to hit the drag strip Fri and maybe an autocross Sun

This is literally exactly what I want to do, except with a t56 magnum and a more built LS3. I was thinking more dual 3" exhaust but I'm not sure it'll fit. I really dont want a single 3" :unsure: though.  I have a couple questions though.

Just thinking here: Since you use different front differential mounts now,  could you cut the middle piece of the old diff mount that has the exhaust bump (that causes pipe fitment issues) and leave the brackets holding the LCA? Also, have you looked into getting aftermarket drop-mounts/dogbone? The stamped sheet metal holding the other end of the LCA scares me, but I'm not sure what aftermarket ones could fit behind the ford diff cover you know?
