damn, triples! more pics of car? It looks well done

Its pretty much a engine bay at this point (rest is undergoing rust repair), he got the car from a shipping container last year up in Norcal. Weird story behind it. It hadn't been on the road since the 80's had a bunch of aviation stuff in it and was locked away in a box near a local airport. And when he finally got it driving on the original motor found out it had a 5 speed and defiantly a cam.


Next time I'm over ill take a bunch of pictures, he also has a very clean auto 240z that he's building a 3.2 using the Robello kit.

I took a picture of my friends L24 in one of his 240Z's just yesterday.

I wanted to share this video. Its not a new one at all, in fact it is a period piece

but the real joy was the emotion / reaction that people still have to this day about it.

Bring a Trailer has reposted the video a few times now and the commentary is fun

add to that is the fact that Peter Brock himself is still around and well, so he just gave his take on the matter too

enjoy!

Great looking car!

I'd like to see dyno charts to back up the 500hp claim though - that would seem a lot even with the 2.2L stroker kit.

Rather than throwing SR20s into everything though, if I was going to mod a Nissan that way these days I think I'd go an S14 with the Rocket Bunny Boss kit. Retro looks, but with out hacking up anything that's actually retro, and it's not like S14s are going to be in any way collectable.

That is cool looking. S13/14s may become collectable with the way the drift crowd is destroying them. I looked for a s14 a few years ago, everything I found was hacked up & 5 times the price it should have been. I was really hoping Nissan was going to build the new 510 concept the put out years ago, similar look to that body kit. Or at least give us a new version of the z car for the 50th anniversary.

Could have sworn I posted this, but I guess I never did.

My buddy’s 510. He’s had this for 20 years. I remember when it got t boned and sat at the body shop did 6 months waiting for a quarter panel replacement.

He had the worst luck with his cars being involved in freak accidents.

You figure out what it was?

Twin DCOE 40s? Mikuni equivalent?

Hitachi SUs with a harmonics issue. I replaced literally every possible thing that could cause the issue, aside from the solid insulator blocks that go between the intake and carbs. (Trying to find a set of the early, rare rubber ones.) A friend of mine in Australia chased this exact issue for a year. The fix was the rubber carb mounts.

The weekend really irritated me. I spent literally every daylight moment working on the car and couldn't get it to work right. My personal car is 18 seconds a lap faster than this thing. That is about the distance from turn 11 to turn 2.

Still the opportunity to race at Monterey was hard to say no to. Also the opportunity to drive a car that has gone to the Runoffs 6 times and finished as high as 4th place (1986) was hard to pass up. No, it didn't run like it should, but it wasn't something easily fixed without knowing what was going on and having the right parts. I'd guess there were 40 people who looked at the car trying to figure out what its issue was, and no one had the answer. There were a lot of people saying ignition system so I replaced 100% of it to no avail. Then people were saying the carbs are too lean and to fatten them up. Ok, well they were partly right, but the cause for the lean condition was wrong.

Considering it was the cars 2nd time on track in 25 years and I had successfully fixed all but the carb issue from the first time out only two weeks before, I'd say the car actually did pretty well. I could have been in the mix with the carbs working, and I wouldn't have been tearing my hair out trying to figure out what was wrong with it. It likely would have been like running my car. Show up, check the valve clearance and tire pressure, go run, come back, give it a once over and go enjoy the rest of the day.

My in car video from qualifying. I had an issue with the carbs the whole weekend that caused the engine not to rev past 5500 rpm. It was tough, but at least I was out there.

I'd rather watch some gentleman vintage racers than a drift even any day of the week. :) Some really sexy cars there. Thanks for the pics.
