FUEL INJECTED WORKS S30 - HAVE A LOOK AT THE IMAGE

Hello,

I am looking into building an race car but still want originality.

Does anyone know if the image of the works  no.63 car would allow for homologation with injection. I just found this image in a magazine and this car definitely ran fuel injection on an L series.

This car was running the same time as the LY28 powered car.

Anyone ?

On a Visit to the UK once I had the pleasure of looking over HS30-H collection of parts. Alan had in his collection a set of Nissan DCOE throttle bodies from the 70's. I believe these were used on the works rally cars, the car you have shown and on some S20 powered cars aka C10 GT-R's.

Alan would be the best to answer how they were homologated  - however the FIA papers don't show injection for the 240z or Z432 - the only injection shown is the standard L28 stuff for 240z/260z/280z homologation.

What class do you want to race it in? Once you decide on that then look up the relevant rules.

At left is a group s historic production sports car, one of the quickest in the country, and for sale, fuel injection all sorted out, flows quite nicely, bolt on a set of 8x15's, and some slicks, upgrade brakes and you would have a reasonable marque sports class race car., or leave as is and you have a top ten finisher in most events.

Or if you want to win spend $250,000 on 911Porsche group s race car.

Our Datsuns are a lot less costly!!!,

Just to repeat what 260det said what class are you looking at competing in?

Haven't even looked yet, I was concentrating on the budget for the build at this stage....... I was hoping to utilise all the running gear from my current 240 (except engine) and return it back to stock standard.

Any suggestions as what class I could run an injected 240z? Looked at the reg's for Historic and it said no injection, but then also says:-

3.1.1 General: Except where specifically identified these general requirements are applicable to all 5th Category vehicles. Further detail requirements for individual groups are listed separately in articles 3.2 to 3.6.

3.1.2 Philosophy: The express purpose of these regulations is to ensure that vehicles in the various groups compete in a condition, mechanically and visually, compatible with the period of racing being portrayed. “Updating” in whatever form is not permitted. CAMS reserves the right to reject any vehicle which it considers not within the spirit of these regulations. Vehicles must conform with the appropriate group date specification in concept and in detail and which must represent one point in time in the vehicle’s history. Where any conflict exists between the requirements of current Historic regulations or the relevant period regulations, and the original period specification of the particular vehicle, the latter will take precedence except where:

• components in a vehicle’s original period specification have been deemed to be unsafe for use in current historic competition;

• components not in compliance with the relevant period regulations have been the basis for the vehicle’s exclusion from a period event; or

• a substitution of component/s has been approved. The following evidence (given in order of priority) may be accepted to prove period specification:

(i) Manufacturer’s specifications as evidenced by manufacturer’s handbook, workshop manual or spare parts list, sales brochures or magazine articles all of which must have been published in period.

(ii) Any document, drawing, sketch or specification produced in period, which demonstrates that a manufacturer’s specification was varied in a period competition event. Specifications in magazines and periodicals of the period should desirably come from at least two sources.

(iii) Reports from recognised experts who have inspected the car. (iv) Of lesser value will be:

(a) Books and magazine articles written out of period by reputable authors. (b) Recent letters or statutory declarations by manufacturers, mechanics, engineers, designers, drivers and

team members of the period. Where acceptable evidence of a car’s actual period competition specification is not available reliance may be

placed on any FIA or CAMS recognition documents published in period for the relevant vehicle model.

In a perfect world I would like to use it for Targa and other road rally events, but track work would also be good.

Looked at CAMS, Aust. Classic Tarmac Rally Championship would be what I would like to compete but I cannot find any reg's.

From a much earlier discussion with Alan T & working from a possible memory deficit, the works 240Z rally car that had the prototype FI was based on a 2.5L engine. They where not homologated as I understand. If Alan has his radar turned on he might tune in otherwise I'll try to track down the discussion.

Incidentally, when you mention Historic, which one? Rally or Circuit?

In CAMS circuit events you can race a fuel injected S30 Z in two classes, Group 2B Marque Sports Cars, like I race in Queensland. In NSW or Vic you would be wasting your time as a Z won't touch the modern cars that race in those states. The second category is Group Sc Historics, if the car is presented as 280Z. This will take a fair bit of effort and you will be in the front half of the field.

The easiest way to get a Sc car would be to take Dat2kman up on his offer and buy his already built Sc 280Z, this will be a lot cheaper than building one.

If you go rallying, I'm not sure on what the rules are, but there are a few guys here who know.

Running injection isn't as easy as you may first think, my set up is going to be upgraded once I can find the money, will probably take the best part of $10k to do what I want. The standard logs are pretty ordinary for flow and the standard computer isn't that good, and if you play in Historics that's what you are stuck with.

Page 16, no.1.10 is the one for you to look at.

I've had a good look down this path, and If you want to run Targa type events buy some 48mm Webers. Other than this rule C3 is a ripper!!

Remember Club level racing is free, So running  lap Sprints, regularities, Hillclimbs etc etc etc it doesn't matter what you have to squirt the fuel into the head.

Bluerat, I think C3 could be the direction I go.

Can swap many parts from my current car to the tarmac car.

Thanks for your help.

Mate, the smart thing for you to do now, before you start building anything is to join your local CAMs car club, if you havn't already. You'll be amazed who lives locally, we have ex Rallyart and Glen Seton racing mechanics, the local TV antenna guy is a gun engine builder, also switched on mechanical engineers, fitters and turners and electricians etc etc. Put your hand up to help out at events, which will give you a heads up on how it all works and runs and takes that pressure off when you do compete, it also puts you in the good books with the above!! If you get a chance try and navigate for someone in local club rallies and pester someone doing a Targa event to be in the Service crew, again both will give you a heads up on how it all works and will be invaluable when it comes to competing in the event yourself. Remember the golden rule..the best money you can spend in motorsport is entry fee's!! get those flying hours up.
