You young fellers sound like doubting Thomas's! Its a FJ24. These were a Nissan Competioin special engine, no they are NOT a bored out and stroked fj20, so forget your thinking about Nissan 2 litre internals.
The fj24 was a purpose built ( approx 500 units made) to go into the 240RS rally cars to compete in the World Ralky Championships, in the early to mid 1980's. Back then they wete developing approx 280 hp and 230 ft lb. They ate a full race engine, dry sumped, external pil pumps, block bracing and thicknesses like nothing else Nissan made, the cylinder heads wer unique, not like fj20 at all, intake and exhaust manifolds were unique to the 2.4. Good gains wete made by changing cam profiles, and going from a 50 mm carbs to 55 mm carbs.
Thete were only 200 240RScars made, and only 30 were the full house competition version for rally use, plenty were converted and up-specced. My engine is one of rhe 30 special built ones. When it eas purchased new, in 1983 the price paid eas $25,000 AUD, or 9000 british pounds from Blydenstein' UK workshops.
There you go, a bit more history!
No disrespect intended, and I don't have a drama with the power output. Keep the gas flowing at 9000RPM and I have no doubt that power level is achievable. It was the specific torque value I was querying. As I said, it sounds awful high. Big cams / big carbs, massive bottom ends and flowed heads are generally built to flow more gas, hence increase power. Getting torque values that high is much harder to achieve, and specific torque values are less sensitive to engine configuration / spec. As I said, even F1 engines are struggling to get over 100ft-lbs per litre, so your claim of 250 ft lbs from a 2.4 seems a bit optimistic.
I remember the 240RS's in rallying in the early 80's, even though I was still more of a tarmac fan in those days. It wasn't till the late 80's I started getting interested in rallying. In fact, rallying is probably the reason I don't own a 2000 Sports today. I bought one in 1995 (U20) to restore, but since I was rallying, I realised that all of my time / cash went into the rally car, so the poor old 2000 sat under a tarp for 3 years till I finally sold it, having done nothing to it in that time. Yes, another of those "if only" stories. I sold it for a song, too.
Thanks for the young fella comment - I haven't been called that for a few years.
Don't get me wrong I'm envious of your fantastic collection of cars there. I think I just realised what car your FJ24 is housed in, too. I'd very much like to come and have a look at it before you sell, even though I'm going to be a drooling tyre kicker with no intention (or $$$) to buy it. Would love the opportunity to see such a piece of Australia's motorsport history. Oh, I'm sure the 2000 Sports will be nice too
