Were the Works '70-1 GT-Rs ever fuel injected?

Many of the Works cars lower down in the pecking order were on carbs - but the top-level Works cars were often on varying forms of experimental FI.

Just to add, the other day one of the roadster vendors let me see a possible "works" head for a SR311 U-20 motor. This head was cast with injection ports directly into the combustion chamber and an additional boss at each port for injector hardware mounting. There was no question that these changes were cast as original instead of machined on afterward.

Nissan Motorsports, Gardenia, was Very interested in the head and took many photos and measurements, but could supply no history or source information. Since only one of these has surfaced, we can only assume it was an expiremental platform built by Nissan.

Alan, were any of the injection methods Nissan used you mentioned a "direct port" method? or were they all throtle body injection?

Well I have evidence and thanks for welcoming me to present it;

1974 James Hardie Bathurst 1000, Datsun 240K came 7th overall and was driven by Doug Whiteford who raced many a Datsun.

And sorry, please tell me why it would have been beaten by a stock 120Y???

There are other links and info I have but the above is just a taste, well enough for you to eat your words anyway.

:sick:

Thankyou! I guess it was raced, just not by Nissan themselves...?

As for you, ben, ignorance is bliss?!?! I thought you knew a bit about these cars...

[JMT240KGTR]

So he thought...:classic:

If you look back on that site and refer to the late '60's/early '70's you'll see the 510 was a pretty competitive car as well.

Also, I think in '76 a 260Z had to stop the race because of overheating.

Some interesting stuff there anyway...

[Ben]

Bah!

Struth - it beat an RX-3, was the Mazda driver asleep?

I still maintain that a 120Y would out-do a L24S-powered 240K as you could run it flat to the boards around the whole track - and it wouldn't need to refuel more than once

I must admit that I haven't really looked into what other models were raced in the ATCC (or previous championships). I believe that that a 1200 coupe still holds a class record around Bathurst....

Now now Ben is like the rest of us he's not perfect. He's pretty good with his history but I think the point about the 120y and 240k was that the 240k is such a big car and a 120y is lighter.

It was a bit of tongue in cheak but I don't think he's having a dig at you 240k guys. I think Ben knows as well as you do that with a bit of work and modification you can extract plenty of ponnies outta a L6.

I've seen turbo 240ks before and I reakon they'd go like the clappers .

Anyway just don't think it's worth getting all worked up over.

If you're in Melbourne and want to see a turbo L28 240K coupe in progress then go to see Lindsay at Z Shop.

One of his blokes is building it; I'll give you a little history on that car. Used to be my mothers car, then mine when I got my license. Then I bought an L28 turbo with my 260Z, so I sold the K to my cousin and said "you can have the turbo if you're going to use it, if not give it back".

Alas, he went overseas and sold the car to Lindsay w/turbo and accessories for a mere $500. I was not happy.

Anyway it's their car now. Got rear GTR flares with huge Jap race rims and tyres, he reckons it'll put out 300+ HP.

By the way, it's straight gas!!!:stupid:

Have a look on http://www.autopics.com.au - there's several pictures of early Datsuns that are cornering so hard that they are to roll. On cross-plys too!

(e.g. the Datto 1000 entering the Dipper).

If only we did get the KPGC10 & 110 GT-R's here, they would have given the GT's & GTS' a real run for their money....

Here's a shot of a 'K' in '75

Don't forget to broaden your search & see various other makes being abused to within an inch of their lives!

[Gav240z]

I have seen that 240k at Lindsy Drife's workshop. However I haven't been in there for a long time I usually see Waz at Zworx these days.

It was a pretty mean project in progress I wish I had that turbo motor for my Z .

[JMT240KGTR]

Thats a great pic Ben; you've redeemed yourself! :classic:

I'm off to buy a 260Z 5 speed now for $70, what a bargain, but I've got to remove it myself. Oh well, a half hours work for a good buy isn't too bad!

After that it's a matter of fabricating the tailshaft to suit the K.

Cheers

[Ben]

Why thank you! :classic:

Why would you need to do anything except balance & replace unis on that tailshaft? It should bolt straight up.

PM me if you don't want to contaminate this thread any further!

[JMT240KGTR]

G'day Ben.

Got the gearbox out of a 2+2 last night, took about 1/2 hour. Before I bought it I checked the first and second gear ratio's (now correct me if I'm wrong, but turning the input shaft

anti-clockwise in selected gear and comparing output yoke turns is the method; correct?, haven't done this in years!)

Now it seems what I have is a 2.9 first gear, and 1.9 second, the rest not measured but at least it looks like I have a genuine 260 box. (if my method was correct!)

I was also under the impression the Z boxes had output flange, not yoke like the 240K. But as I say, the ratios tell me it's a Zed.

What do you reckon???

Jim,

As far as I know, it was only the very early 240Z boxes which had a flange to bolt the tailshaft to, and this was also used in conjunction with a two piece shaft. The later Z boxes (well all the ones I have seen) have the slide in system where you just slide the shaft onto the splines. hope this helps a bit

Cheers Chris
