That ad has some very good imformation and I feel that it should be preserved on this thread as ebay will go away this imfo shouldn't.


It needs some things, but NOTHING is stock but the windshield... Tube reinforced frame, Carillo rods, Arias pistons, roller rockers, Isky cam, Quartermaster clutch, dual SK 45 dcoe carburetors's, close ratio race trans, kiezer wheels, disc brakes, optional different ratio rear ends, accusump, sparco seats, oberg oil screen filter, big custom radiator, oil cooler, full guages, racing springs, adjustable front a-arms, MSD ignition, racing distributor etc. I think it has been a racer since '73.

Good call Calvin, that will save people like me about 2 months of searching on this site, or about 10 years of trial and error.

I wish I had the space/finances for another racer. That looks to be a well sorted car, and would be competive all day long. Although, I would probably never get that one to the track either.

[cherokee]

I agree with you madhatterpdc...I would have been hard pressed not to buy it 12 months ago, but now my car is so far along I doubt that the wife would approve, of me having 3 race cars...anybody want a 85 ITA MR2

[montana]

THanks for the cut and paste. There is a lot of good info supplied to me by the previous two owners compiled here. It took the "Oh crap I just bought a used modified I don't know what" fear out of the picture when I bought it. I hardly knew what a GT was beforehand. I just wanted to race and the car had a good rep. albeit the previous owner/driver was an excellent/consistent racer. As a newbie I did pretty well after I found that peaceful dreamlike groove that the car likes. She likes to be on the pole

[davegt27]

that sounds like a Manta-part motor

i herd about a guy years ago that ran direct connection dist

Rally Bob could probably fill in more info.

Hey does anybody know why only one person made a bid on this car in ebay? It didn't sell and I am considering relisting it. I would appreciate any sugestions on things to change in the advertisment.
It's a great car for anybody that wants to race. It's a GT....
GT's make good racers for a bunch of reasons including: Large frontal downforce, all four cylinders behind front wheel centers...etc.

[GTJIM]

It is not that we wern't tempted - just too far away and another "money pit" is not a priority. Someone wants it! Great info though - and I have an Isky OR-99 cam in a Norris Kit ......

[calvin]

The car is great the price is right.... the market isn't big enough..

That car should be advertised in grass roots motorsports and classic car


the active racers here have cars, stan ,bob, greg and others. the people who look for opel on ebay are opeler looking for a deal

The maybe someday wanabe's crowd (like me) could maybeeeeee afford the car .... but then I could not afford the time and expense of a season. Joining the SCCA isn't to bad ($70) but add another 2 grand for driving school along with competing costs plus a truck to haul the thing... that is a competitive car, it should have an owner that could afford to compete..

there may be people who can afford to compete here but for the kind of money the car (rightfully) commands they might want to build there own.

you need to find someone like me without to much sense, a wife who is out of town and has capital to swing everything. That is your buyer and he is not looking on the opel sight or ebay... no he is reading a racing car mag with dreams of glory and podiums in his head.. take the dream to where he is looking.... GRM


=== now if you don't mind tell me about those spark plug wires.. where do you get them? I go to an auto store they say "what year and model and then they say we don't list those kind of plugs for your car so unless I can tell them I want solid core XYZ plugs I am SOL

thanks,
Calvin

I'd be really interested in it myself...but like someone mentioned...it'd be another money pit for me right now. Anyone up for a group buy in the NW? ....form our own race team...

Most likely because 'tub' cars generally aren't competitive any more, everything on the front row is a tube chassis. That, and Opels need a bit more TLC than a lot of other cars, simply because every racing part on the car is usually custom, very little comes from off the shelf parts bins.

As a historic car, it's tempting, however I have personally seen a lot of 'attitudes' from vintage organizations regarding Opels. Not old enough for many cutoff dates (usually 1968), and not interesting enough historically for the modern-day classics.

And as mentioned earlier, most Opel owners are looking for a 'deal' of the century, few are willing to ante up the cash.....

HTH,
Bob

Montana,

There is lots of info missing from the add that I would consider mandatory in selling/buying a car like this.

In no particular order

There is no indication of it's competitiveness. Has it ever won any races, championships?
Who built the motor? Dyno sheets? Head flow numbers? Measured compression ratio?
Suspension information, bushings, heim joints, adjustable, geometry improvements?
Is the motor fresh, tired, somewhere in between?
Shocks, $15 tired Monroes or $1500 double adjustable Penskes?
LSD? torsen or friction style?
Weight? Weight distribution?

One down side of the suspension being in front of the motor is that it's a long way from the front hoop of the cage. There is LOTS of opportunity for flexing up front. I see no tubes to the firewall let alone the front suspension.

One thing you have to understand about selling a modified GT is that it will never sell for even a fraction of the price you have into it, if it will even sell at all. Everybody wants a pristine car that they can do whatever they want to, not inherit somebody elses ideas. In pieces the car would have sold but all together it will be tough. Just as an example the intake is on my shopping list but not those SKs. There are a few other items I'd be interested in but not the whole car. There are probably a few more people with the same thoughts as to the pieces but not the whole. I wish this was not the case but if you watch what sells and for how much it's easy to figure out. Performace parts are worth alot and a modified car is not, go figure.

[cherokee]

I think that the main reason is because it is an opel. You are trying to sell something to a VERY small group of people (racers), and then you narrow it down even more in looking for an Opel racer. I would doubt that there are 10 running SCCA,NASA any vintage org. that you can think of. If you want to sell it I would list it here and eventually someone will come along (every opel person I would bet comes across this site)...I would have been intrested but my car is almost done. Nothing wrong with the car you are just selling a car to a very small group of people. The price was ok I think, it is less then I have in my ITB car and it ain't done yet.

Montana,

It is a regional butt kicker (depending on where you are I supose). Bob is right about the "tub" factor for national scca, but for regional or club it is a winner. Wanna race?.WANNA WIN REGION OR CLUB?..here ya go... If someone wanted to search archives of Midwestern Council of Sports Car Clubs (mcscc) they have it online. One would look for Pete O'Connell (me)or Ed Key FROM in '93-'99
Some operator error dnfs and one mech... fatiqued driveline torque shaft
Who built the motor? Ed Key w/pro help
Dyno sheets? No
Head flow numbers? No
Measured compression ratio? 11.5:1 theo

Suspension information, bushings, heim joints, YES
adjustable, geometry improvements? YES
Is the motor fresh, tired, somewhere in between? FResh

Shocks, $15 tired Monroes or $1500 double adjustable Penskes? Former
LSD? torsen or friction style? can any body remember what it stand fo? ..lysergenic sodium dioxin..no that's not it....
Weight? Meets #2040 spec with #25 lead low inside
Weight distribution? dunno but car has neutral drift

One down side of the suspension being in front of the motor is that it's a long way from the front hoop of the cage. There is LOTS of opportunity for flexing up front. I see no tubes to the firewall let alone the front suspension.
CAGE IS TIED FROM REAR SUSP TO FRONT THRU FIRE... VERY STIFF

Hi Pete, sorry to hear that you are getting no bites on your car. I sure wish I could buy it, heck it's only a hundred miles away from me.
I never did hear just what you want for it, nor have I seen any pictures.
I'm gonna mention this to a guy I know who has lots of money and likes neat toys, tell me where to see pictures and how much money might be involved...
Speedway GT is just about race ready, we took it to the track last weekend to show to the disbelievers. It drew quite a crowd!!
