Help with value on Porsche race car

I am considering the purchase of the following car, and would love some input on what similar stuff is going for these days. Intention would be mostly for HPDE events, maybe some NASA type events. No concern with being competitive or winning anything. Just want to learn and take the next step from my Miata track car. Maaaaaybe eventualy do a WRL effort if the car would be acceptable to that body. From searching listings online there seems like a large spread, aside from obvious differences from car condition and prep level. I have not discussed a firm price yet, but wanted to have a rough idea what the ballpark even is before proceeding.

Here is what I know:

RSR body
PCA logbook
It's a 79 chassis w an 84 3.4L twin plug engine
JE pistons
Pauter rods
JRZ coil overs
Big Red brakes
New MoTec ecu, dash, with new fuel injectors and custom wiring harness
ATL fuel cell
All lexan
Halon fire suppression
Driver seat + removable passenger seat
Red top battery
Harness/fuel cell have 2-3 years left
Raced about 8 weekends a year for last 2 years. Private track club stuff.
2 sets wheels/tires
Do not know hours on engine but compression and leakdown are good, serviced by well respected Porsche race shop.

the nice thing about used race cars is they make the depreciation on an FF look spectacular (half kidding).

This car resembles (closely!) my old Porsche race car....started out as a 76 930 tub, and in the end was a caged-out, plastic bodied, up-modified (every component) car. Fast as hell, challenging to drive and a lot of fun. Perhaps not the best developed or refined package though....(we referred to it as "Frankenstein", and when people asked what year it was, I had to respond "which particular part"?).

FWIW, in 2010 I paid $50K for it with a really good 28' Classic trailer included. Swapped the trailer for something smaller, drove the car a LOT, serviced it perfectly, did a few enhancements (brakes/bias control, new ECU's, shifter), sold it on a few years ago for $50K. Had I had much more patience than I do, I probably could have gotten more, but the "used old modified Porsche race car market" is a bit variable; particularly with what you can get in a used race-spec Cayman.

Wont' judge this car at all

I was literally thinking the same thing. Excellent.

Sorry for being off topic.

What is up with that cage? Looks like an off the shelf cage that is a bolt in that was modified to be a weld-in. That already is a negative to me. Then there are the unsupported pseudo NASCAR door bars which are the worst in safety design. At a minimum I would reinforce the psuedo bars and support them at the door sillplate. That means more welding and new paint. If you are not taking passengers you can leave the passenger bars alone and save yourself some money. NO race ready turnkey racecar is ever race ready!!! That is just life. That unicorn does not exist. Take it from a long time racer.

Good observations. He said the cage was to PCA specs, but I'm not sure what specs and as of what date. I also noticed what looked like bolted connections that were then welded. I will find out more history/details on it. When you say to reinforce the NASCAR bars, do you mean with connections like I have drawn in red? That is how I have typically seen them done. Our Miata chump car has three drivers side door bars and two passenger side (although no ability to install passenger seat in that car).

Also, what are your thoughts on the short sections where the tubing is a larger diameter? Almost looks like a coupling or something that was welded in. Is that an acceptable thing to do?

I'm very conscious of safety stuff when it comes to any track time, I'd rather spend money to make the car safer 10 times over before spending any making it faster.

Would you recommend adding anything more than what is drawn in red? I think I'd want a third longitudinal bar as well. Circled areas are "coupling" looking spot I mentioned.

I would add your red bars plus these pink bars supported to the sill plate with white outlined square plates welded to the sill. You want the square sill plate supported to be bent 90 degrees so they are on the sill plate and on the vertical wall of the sill too for best support. It looks to me that the collar big tubes are slide and bolt as part of a bolt in cage. That set-up of welding to convert a bolt-in cage to weld-in is legal for SCCA I'm pretty sure but I would have to read the rules. However I think the sleeves as they sit are not SCCA legal. I think you can sleeve tube for example when doing crash repair but you have to rossette weld in addition to welding around the big and small tube junction. The rosettes would need to be 6 places equidistant over a joint not a bolted in welded over bolt.

So I would say to the OP. What do you want to graduate to? HPDE buy anything and any cage is mostly better than none for HPDE. If you want to race SCCA then look at their rule book. Google SCCA GCR and start reading for a possible class and rules for cage construction. If you got questions I can probably help a bit. If a car is SCCA legal is usually meets NASA too. SCCA is just a bit tougher in standards than NASA. NASA has a good HPDE competition program and racing. Bigger dogs still race SCCA. If you want to race PCA or POC then read those CGR's. If you already have a PCA logboog but it's cage standards were lower at that time can you still get a new POC logbook or SCCA logbook? Many organizations allow crossing over with less headaches if there is an existing logbook. If you have no logbook and start fresh you need to meet today's standard as a new racecar build.

..
The 3 bar nascar bar can be unsupported and often is because of rules. Many rulesets limit the number of cage attachment points often 6 or 8. If you weld to the sill plate you just added 3 connection points. Under your conditions in a 3 bar doorbar the lowest bar is call a sill tube. It is welded near the sill of the car in an area that is typically below the bumper impact zone of another car hitting you. So the two upper bars are really the nascar support protecting you and the 3rd lowest sill tube supports those upper bars.

If you are really into safety full containment seats are what you want if you can fit them in a spec miata. In chump you got guys out there in 3500lb volvos and you got a 2200lb miata. At least in SM everyone is the same size.

This is pretty much what I have been thinking. I like the idea that it's a little of this and a little of that. Therefore it's something that can be used as strictly a tool to go have fun, without worrying about damaging a more original, valuable car.

Maybe 30-35k$

I might end up getting a dedicated track car. Right now have a 930 with a bunch of safety equipment added. I know it's no longer a virgin now... But there will always be a buyer for a 930 I figure.

If you ever plan to sell, get something that fits a race class. Spec boxsters seem to be $35k to $50k...

Gutted 996 for track work, but no race class, about $25k...

What seems like the best deal for a car to beat on, is a spec 944... Maybe $15k... Not fast, but cheap. And I do see them run in the fast groups...

eBay seems to have tons of cool, cheap, race cars...

Yes! How freaking cool is this?!?

Formula Mazda Race Car, FM, John Player Special | eBay

Long term I'd love to have a formula car of some sort, although honestly would prefer Formula Ford or similar with no downforce. I also like the idea of vintage racing in general, so could get two birds with one stone with FF. I'm afraid I may not fit though, at about 6'1", 230 and broad shoulders.

More on topic, here is a similar vintage 911.

I have seen used Indy cars for $40k...

Safe? Probably not...

Practical? Hell no...

Lots of places to run it? No...


But how cool would it be to have one in the garage?

Drool...

IMO the original FM's are not safe. They are formula contintal fast, with a formula vee cage. Very bad combo.

It's pretty cool. Mine's only a roller, but the steering works and people like to sit in it and have their picture taken.

I would say mid thirties for price. If you have the pcar bug and can swing it you may want to look for a 996 cup car or a retired Conti race car. From what I have seen in the market they tend to hold their resale value, have excellent safety equipment, are pretty reliable and can be run in multiple series if you decide to race.

Agreed. 996 Cup is the deal right now. Also, the 997 GS Conti cars, built by a pro team like the ex-RumBum car, would be awesome.
