So, is the best update placed here or at the zhome site? I have one to add.

Good to know, I suppose helical gears give out less frictional heat than clutches. Installing EGT at those cyl locations sounds optimal, should be my next upgrades, only have a boost gauge for now. Our track days here are 4 or 5 x 25 min sessions, and it does get hot, 95+F in summer months. Any best recomm for Z32 tranny fluid, Nissan OEM synth, Redline, ? and what viscosity?

This shouldn't decrease value, need to beef up the R200 for tracking, will watch temps and change fluids often.

As I said, the cage is not a 'full' cage per se, it ties the front and rear hoops with the low door bar and welded at the below location, and under the roof. At this point I'm not pushing for the legal SCCA/NASA rules which requires a dash bar across the width of the interior by the windshield, this may come in the future. The current cage ties at 8 points, actually, on the chassis and rear strut tower. But, it IS easier to access the passenger compartment with this design. An underdash bar will be added for side impact protection. Pic of how it was years back when pre-built

I want to get baselines first, now on stock turbos, minor tune at 8.5 lbs boost, just under 260whp. Car was also cornerweighted, 2450 lbs with 8 gals gas, no driver. My target is the E46 M3 I'm pushing now at the track, which I will sell soon. We'll see, but I'm looking for stepped upgrades w/o destroying much of the exterior aesthetics. But, safety has to be addressed first! Yes, and I understand while driving it occasionally on the street there is the risk that cage can do major damage, but can't do anything about that, keeping my belts tight is the best I can do.

Points well taken, I can in no way compete with stock value. But my goal is to track safely, this is an OLD structure, hence the 6-pt roll bar/cage to tighten it and under-floor mounted ATL cell (will be per SCCA specs) for crash safety. It is after all an RB26DETT hybridZ, not going back to stock. Also keeping most mods period correct (BRE, ZG), and planning on only 5-8 track days per year, the rest enjoying shows and Z car events. Right now car and mods are about $20-22K.

Yeah, the Reserve was not met on that recent auction, thanks for the link and example. I am keeping any upgrades, esp. requiring welding, to the minimum, preserving the chassis as much as possible. For tracking, though, I do need at least a solidly braced frame, hence the roll cage, much safer to reduce flex and better crash worthiness. I suppose keeping upgrades to a time period might be more desirable - ZG flares, Watanabes, fender mirrors, engine type, etc. - targets a more specific market. I'm not adding a wing for aero's sake, BRE spoiler will do.

Good points, makes sense that back-to-stock would be the harder conversion. The spare tire well has been cut out, but the only mod on the floor so far is the sheetmetal to cover up the tire 'hole'. I'm all for keeping the rest of the floor stock which is still in great shape. The fuel cell location matters, must be totally out of the passenger compartment, safest per most race orgs. What I want is, instead of cutting out the floor area the size of the tank, I'm opting to mount the tank underneath with 1" sectional 'cage', and a trap door for fuel filling. Hopefully the trap door can be at the same tire metal cover so not to cut out any more of the stock floor. The cage will welded to the side frame rails behind the rear tires and the Aeromotive fuel pump and dual filters will also be mounted under the floor. Great idea to take before and after pics of any area to be welded for chassis bracing or fuel cell mounts. I'm already documenting on a spreadsheet all the mods, install dates, vendors, etc. My track days will not be too extensive, 5-10 events per year, other times will be attending club meets, shows, cruises etc, the fun social stuff Keep the suggestions coming. Oh, another aesthetic, will my body colored ZG flares add or diminish value?

I know this is a 'tech' forum but just can't find the best place to put this. Chit chat forum, or ? And guys, I searched did not pull up anything. Anyway, I'd like to keep my S30 as clean as possible to keep its value. I know that my 240Z is going towards a track day build but still keeping it streetable (brakes, lights, signals working, registered). This is not a daily driver, though. It has a 6-pt cage and will add box section for secure fuel cell under-floor mount (road race legal) for best safety, etc etc. But, compared to orig stock examples out there, how can I preserve its value? Do tracked Zs fetch much less than stockers if not abused? For example, will cutting into the floor for the cell and welded-on chassis bracing lessen its value, marketability? How about my engine swap? Or, it won't matter as long as the car is kept away from rust and maintained in and out? I know there are different markets out there but comments and past experiences? Thanks for your inputs.

Hi all, I figured to post here before looking for more inputs, suggestions, experiences. Basically my track day project is almost to completion, and I'm excited to report upgrades, issues, misc set up comments. The year of tracking just begun, glad to jump on this site, been looking at other posts, nice community. Yes, I'm also on hybridz but hoping to get different views here. More details later but this car has an R32 RB26DETT with Z32 5 spd, Z31 R200, EMI/Eibach coilovers, Wilwood discs, 6-pt cage.....not done yet. Will be installing a better fuel cell system very soon as I'm really pushing for best safety. Current tune/baseline is mild, 8.7 lbs boost, 258whp on Dyno Dynamics SAE corrected. Car with 8 gals fuel weighs 2450 lbs, cornerweighted, my weight addtl.
