Looks like it went for $15,600, with 14 bids. Quite surprised by that, but obviously it struck a chord with a few people.

I've long since lost any faith in Nissan to build anything small and light when it comes to a sportscar... Too bad really, since it's something they used to be great at. Now they would rather over-engineer everything and give us a big, heavy, lump of a car, rather than a small, exciting, spritely and fun drive. Ah well, I own a 240Z, so it's not like I would buy whatever new car they release anyway - shame to see a legacy die though.

Very polarizing car, done to a very specific taste. Not my thing at all, but to each his own. I feel like the paint job seemed like a good idea in theory, but doesn't quite work in practice. Something about that car makes me worry that the buyer will find a lot of "gremlins" in it. I also have to question the outlandish HP claims, and seeing nitrous is always a red flag to me when I am looking to buy a car. Maybe some 18 year old with lots of money will buy it though? Simple explanation: Loud music. It's not so much a pursuit of sound quality as much as it is the pursuit of being able to blast your tunes at outrageous volume levels - the sort of levels that your neighbours would call the cops on you for if you did it in your apartment. I actually miss having a good car system for this reason. It can be kind of therapeutic actually... Too bad my Z is such a sports car, so I'll just have to settle for the scream of that straight six instead

Might as well post an update, as I have been going through a pretty epic struggle with my 44's over the past few months. I'll post more on all of that later though, as well as a very detailed strip down and rebuild of a Mikuni 44PHH to help others and save them from the potential mistakes I made. So, as it stands, I am now running: Pilot: 55 (1.75 turns) Main air: 200 Main fuel: 150 Outer venturi: 34 Idle: 12.4 afr 3000rpm in 2nd (30mph): 13.0 afr WOT in 2nd: 10.5 afr Still running very rich, in spite of running a much larger air jet. I do have a set of 140's to try though, but I find it a little confusing that others are running 160's and getting much leaner figures... I also have a set of 37 outer venturis that I will throw on and see what happens with. In spite of my AFR's not improving, the car does pull remarkably harder now, and it seems there is still room for more improvement. Before I had some stumble when flooring it, now I don't. I also used to have a little stumble in 3rd gear around 5k RPM and it is now gone. Best of all though, I can now floor it in 2nd gear at around 30mph, and the rear tires will actually break loose around 4k RPM and not catch until I go to 3rd. Very addictive! I also now get 115 miles from 30 litres of gas, whereas I was getting more like 75 miles before. So I went from about 9.5 mpg to 14 mpg. This is under spirited driving and city driving, obviously. I get almost 25 mpg on the highway at 70 mph. Winter is now here though, so into storage she goes. In Spring I will be trying: 50 and 52.5 pilots 140 fuels 37 outer Venturis Will probably go ahead and see what the venturi does first, with my current jet set up.

Thanks for sharing. I've no idea what I have for internals with my engine, purely the previous owners listing and an old barrett-jackson listing that state the car has a 3.0 stroker in it. Given all the other toys on the car, it's likely true. I should go ahead and at least see what cam I am running though. I think I will head towards the jets you have posted though, shouldn't be too far off what I need. I am running a 34 choke already.

Can't log, not set up for it. Have the gauge mounted on the steering column though, so my eye is on it as much as it's on the speedo and tach. Might take the car out into the country for a good rip tomorrow, and record the main cluster while doing so. Would be good to review. Either way, looks like I need a higher number for my main air jets from the looks of it? Not sure what's up with the pilot's fluctuating in numbers like that. When I bought this car 2 years ago, it ran very poorly. Suspected it sat longer than the previous owner indicated and I took it into a Z-specialist shop to have the carbs cleaned, rebuilt, and properly tuned. It ran me $1350 for this service - I'm questioning that investment now. I knew it was running rich, but couldn't tell just how excessive it was until I got the wideband installed. Ah well, the rest of the car is doing well, so I am ready to sink some time into this area and learn all I can.

Just opened up the suckers today to see what the hell was in them... Cylinder 1 - 2 - 3 - 4 - 5 - 6 Main air jet 170 - 170 - 170 - 170 - 170 - 170 Main fuel jet 140 - 145 - 145 - 145 - 140 - 140 Pilot Jet 52.5 - 55 - 55 - 55 - 52.5 - 50 Pilot screw was 2 turn out from seated.

Great thread, very informative! Time for me to join in all this fun... Just got my wideband (AEM UEGO) up and running, and was pretty shocked at the numbers I was reading... Warm idle AFR @ 1000RPM - 11.4 4th Gear @ 2000 RPM - 12.5 WOT - 2nd gear @ 6000RPM - 10.5 A little rich, shall we say? Running 44's on a 3.0 stroker. Pulling the jets tomorrow to see what I have in there. Had these carbs rebuilt just over a year ago by a reputable shop, so all else should be good.
