thanks for all the useful info. ive had the car for 6 years now and done nothing to it its imported from the states and has imsa fenderflares on it now. looks like about the same that bob sharp cars had the small ones with the standard front end (not the g nose vwide fender)

 

its been standing in a car museum a few years now next to a NISMO skyline gtr r32 1 of 3 group N cars in europe in the motorsport section. very nice skyline by the way 100% original and never restored.

 

were these cars running under FIA? any body know? https://www.youtube.com/watch?v=ZAcyY4Sv70o

 

in the text it says year 71 and ly28 2870cc thats how i would like to make my car.. i have the group 3 homologation papers just to a look at them and im shure there are papers missing. is there group 4 or 5 homologation papers separetly to order?

 

here is some specs about the GTS car http://nissannews.com/en-US/nissan/usa/releases/datsun-and-nissan-fairlady-z-heritage

You are misinterpreting the data on the Nissan Heritage Collection web pages. The 'Oppama Test Car' seen in the Best Motoring video was originally a 1973 car, but was developed - and tested - in many guises through the 1970s, and eventually became one of the fleet in the Nissan Racing School. It didn't race in 1973 with an LY28, let alone in 1971.

 

Cars in roughly that guise did take part in FIA-sanctioned races, but they were in the Group 5 class and occasionally in Group 4 (depending on final spec.). They didn't use N42 or F54 engine blocks. Generally speaking, you won't be allowed to use an L28-based engine for properly enforced FIA events in Europe.

 

As I said further back in the thread, the people you really need to talk to are the eligibility scrutineers for the series/races that you intend to take part in. You need to pick a class that you have a chance to be competitive in, and build the car to suit the rules for the class.

thanks,

 

were these cars in this video clip 1min40sec fia cars? i dont speak japanese but i understood that it is from 1973 and gts competition???https://www.youtube.com/watch?v=h71XNJVCj8k seems to go pretty well and thats how id like my car to look like if its "legal" in europe.

 

we have 2 types of historic racing in finland FIA and roadsport both for old cars only. in FIA car has to be period correct in road sport you see cars like sunbeam stilettos with supercharged suzuki hayabusa engines.. and MK1 cortinas with BMW multilink racing suspension. so if i want race in road sport i just but a 4wd skyline or a WRC car and transplant it in my datsun.. but i ilike my datsun way too much to destroy it. and it was built like a racing car in the US a long time a go so have to get it back racing on the track again. easiest would be to build a Rauno Aaltonen safari replica and sell it for profit. but thats not how my 240z want it im shure of that.

 

i want to build a period correct car not any cheater car. have seen many escorts in historic racing with 3way öhlins adjustble shock absorbers and xenon light pods for example!! thats just wrong if you ask me. for historic racing the car has to be 100% period correct exept safety equipment rollgage and so on. thats how i feel.

 

if they ever raced on track with 240z in europe is there separate group 4 or 5 homologation papers for it? or did they use different homologations for them? fairlady z called in japan did it have different homologations in japan? or maybe us did they do racing under FIA there??

 

for example a Lexus is is 6 cylinders in europe and when they started to make them like rally cars in finland they used toyota altezza (same car but 4 cylinders engine in japan) fia  homologation papers for them to put the altezza 4 cyl motor in the car... less weight for rally use.

 

maybe they have done stuff like this in the past too?? and some people say its ok in a 240z from year category 75up with a 2.8liter engine? its homologated in my papers too but as a fuel injected motor and underlined 280z. but my papers came with the car and seems to be some missing and also dirty and poor quality.

Like Alan suggested, go to a FIA type event and talk to the workers in Tech and also other competitors.  If you go to the Copenhagen Grand Prix look up Stefan Winquist.  He runs a 240Z  and I supplied him with chassis and suspension parts a few years ago.  He had to jump through some hoops for the brakes but we ended up getting the Sumitomo S12W calipers approved after doing some machine work on them (removing some ridges) to make them look like the period correct FIA calipers.  Most vintage racing organizations do not require 100% FIA Group 3,4 compliance.

Hi i have 4pot callipers already on my car they look the same like sumitomo i hope they are the right ones... but in the rear it still has the drum brakes.

 

 

 

some videos from historc racing in finland.

Here is my brothers 355 hp M3 in rally finland last year very nice sound https://www.youtube.com/watch?v=4nSzd5E2-Nc unfortunetly he jumped over 45meters on the 2 stage and broke the radiator, oil sump, front suspension, bumper, sump guard and so on.. he was leading RWD class at the moment. WRC cars didnt jump any further.

Going by that 'historic racing' video it looks like there are no rules, drive what you bring As the experts have said, check out the situation at the tracks where you want to race, talk to the officials, check the cars out, see what you have to do to get to go racing. Enjoy.

Im not trying to hunt you away from classiczcars,......

 

This is the racing forum, why would you want to encourage people to go to another site?

Sorry forgot to say that in this video you see historic racing cars and roadsport cars mixed, its a trailer for a video. In road sport you can do basicly what you want with the car it just has to be 1997 year or older.

Did get some info today about the l28 from the motorsport organisation in finland. It is homologated 75. Still waiting if it is homologated like a evolution or just a ad on part. If it is a evolution part then the car has to be probably made to 280z specs lights and stuff like that. I Hope not! if its a "ad on" part you can put it in a 240z for 75year category in fia racing! Im also waiting for a list of parts they banned in group4 racing in 76 by fia. A bit same what happend with rallying in 87 after grop b was banned. So i hope i can use the 2.8 in a 240z?

There is also the question of how much money do you want to spend on the engine and what modifications to it are allowed. For the right money good power can be made from a smaller capacity L series engine, see http://www.performanceforums.com/forums/showthread.php?67302027-Doing-some-stupid-$^!#-to-an-old-datsun-head

How does 237hp @ 7250rpm from a two litre suit you?
