Ejkej Posted January 11, 2010 Share Posted January 11, 2010 Hi! I hope to get some help from You guys! I bought a 280Z recently, and want to register it in Poland as a vintage car. It is a special category for special vehicles and it has important to me advantages. There are some restrictions though. One is that I need a 75% originality of the car... and my Z has willwoods, and coilovers on 4 corners. The question is: Does anybody know if those modifications were made at the time Datsuns were in production? Thanks Quote Link to comment Share on other sites More sharing options...

Ejkej Posted January 12, 2010 Author Share Posted January 12, 2010 Well, I know who makes them, and I always use search option before asking anything on any forum. What You should learn is to understand people who use english as their second/third language, and might need some extra help from such a skilled members like you. What I wanted to find out is if the conversions mentioned by me in the first post (4 disc brakes, coilovers) were made to Zs at the time they were produced. E.g. - somebody bought a Z in 1976 and than went to a racing-shop and did those conversions to have better driveability. Thanks Quote Link to comment Share on other sites More sharing options...
softopz Posted January 12, 2010 Share Posted January 12, 2010 I think you should ask arizonazcar I do know they have been around in the 80's iam not sure 70's . How could you prove it though? Quote Link to comment Share on other sites More sharing options...
Daeron Posted January 12, 2010 Share Posted January 12, 2010 This sounds like an awkward situation. Being unfamiliar with the laws in your country regarding vehicle importation, most of us are at a severe disadvantage. On top of that, alot of us are Americans, so some of us kind of ignore the fact that other countries exist. Sorry about that!!! The modifications that you mentioned are in no way stock or factory, and although they may have been somewhat contemporary I doubt it would count as "original." In other words, unless "period-correct modification" is allowed I would say the suspension and brake mods count against "originality." Coil-overs are basically just macpherson struts with adjustable height, though, and brake upgrades (especially something as simple as adapting Wilwoods to the car) have been around as long as we have had race cars... so I may be wrong. There are a few European members here (one i believe is frank280ZX but that may be frankS280ZX or some other variant.) You might want to try to send a PM to one of the moderators requesting a title change for your thread indicating that you are in Europe and have questions regarding importing a vehicle. Or start a new thread with a different title. Quote Link to comment Share on other sites More sharing options...
Ejkej Posted January 12, 2010 Author Share Posted January 12, 2010 Thanks for the advice - I will ask them . However, I don't think that I need to prove that wilwoods were used in 70's. It would be enough to get some info of any 4 disc brake setup being used in racing Zs from 70's. Some pictures, maybe advertisments will do the trick. Same goes with coilovers... Any idea where should I look for it? Daeron: You are right on the originality issue with suspension and brakes - there is no way they will go as original parts. However, if I prove that those modifications are "period-correct" I will have strong argument in fighting for my Zs "vintage car status". I don't think that changing the title to one regarding importing is what I should do - I want to find some info on Racing Zs from 70's and modifications from that period . I will ask them to change the title to a more precise one or move the thread where it belongs. Thanks! Quote Link to comment Share on other sites More sharing options...
ModernS30 Posted January 12, 2010 Share Posted January 12, 2010 Sorry I misunderstood what you were looking for, I didn't think about English so I won't be an @**. I believe they did use coilovers and 4 wheel disks in racing on the datsun's back in the day. Even if you threw ZG's on there it should still be period correct. The info below doesn't state there were 4 wheel disks or coil overs, but every trick part known in that day means it had disks, and I'm pretty sure we had coil overs then as well. 1972 DATSUN 240Z The old race car. Bought it new in 1972, and sold it in 1980, but this is where the love affair began with this breed of cars. Mostly fiberglass, 280 block .40 over, early 240 head with triple Mikuni Solex carbs and every trick part known then. Car weighed 2100 pounds and turned out 310 bhp. Handled like a dream! Won a LOT. Picture of this car. Quote Link to comment Share on other sites More sharing options...
Ejkej Posted January 12, 2010 Author Share Posted January 12, 2010 Thanks for that answer Notsurewhattoput. It was probably my fault You didn't understand what I was looking for... ;/ Peace. Quote Link to comment Share on other sites More sharing options...
MAG58 Posted January 12, 2010 Share Posted January 12, 2010 If you're looking for old race-car information, including if any cars ran what kind of components you'd like to run, and may not be able to find such a race-car, PM TonyD. He probably has a race-car that will get you in, either in the states or Japan. Quote Link to comment Share on other sites More sharing options...
Pharaohabq Posted January 12, 2010 Share Posted January 12, 2010 Though you may be able to just tell the authorities that it is all stock, since it's VERY unlikely that they would know that 4 wheel disc brakes weren't availible of not in the 70's. Much Less any other parts So likely you wouldn't have to worry about it. Beside that, 75% originality is still very easy to prove. it's 3/4 of the car. so all body panels, seats glass and engine would qualify as 75% I would think.

Jon 74 260Z Posted January 13, 2010 Share Posted January 13, 2010 I was thinking the exact same thing that Phar wrote... Having zero experience registering cars in Poland, I would still advise you to talk to someone else who has gone through the process. I would thnk that they would be able to tell you if the inspection is detailed and thorough enough to know what is original and what isn't.

johnc Posted January 13, 2010 Share Posted January 13, 2010 (edited) Look at the rule sets for US based vintage racing organizations.

310z Posted January 13, 2010 Share Posted January 13, 2010 I also was thinking the same as Jon and Phar. However, the book How to HOTROD & RACE YOUR DATSUN 1994 By Bob Waar. is a era correct book that has all of the old factory optional components listed that were and are available through Datsun/Nissan Competition. If they were dealer options and or factory race parts you will probably be able to get away with it. As long as there are not any classic Datsun freaks were you are registering the car, I would think it should pass easily. Breaks and suspension do not add up to a large percent of the car. G noses and ZG flair are all factory parts that were available through Nissan and much more. The book is a cheap way to check things out and if any questions are raised, you have the book to show anyone who might question you the factory Nissan parts numbers.: Quote Link to comment Share on other sites More sharing options...
