They have been on there since my first dyno. I think the difference would be minimal. Like changing tire pressure or air temperature you might be able to get a 1-2hp difference, but really... c'mon.

They are much much heavier. The stock 7.5" wheels are 16 lbs, the 350Z wheels weigh in at a collossal 23 lbs for the front and 24 lbs for the rear. It is why I mounted my race tires to the stockers and roll around on the 350Z wheels for everyday use. I'm more concerned with the weight of the car in race trim than for everyday driving around.

I had planned on purchasing a new set of lightweight 17" wheels with a greater width for street use this year, but I may just get new tires for the stock TT wheels that I have (17lbs) and run those all the way around with a 245/45/16" ExPerf Tire and run Street tires at Autocross this year.

Hehe. I've actually never owned a car with nitrous and though the idea is tempting, especially with some Branson Drag racing coming up, I keep having visions of taking everything out every time I want to Autocross and what a pain in the flipping arse that would be.

I'm not quite sure what my next power adder modifications will be, but they will be after my next suspension modifications for sure. It'll be sometime in fall, probably right before the KCZC Fall Dyno day before I make any more power.

Here's hoping for a sub 15 second pass at Branson... woot.

definately love everything that youve done...in the process of doing the exact same mods to my J...ive already done the underdrive and overdrive pulleys, popcharger, and full exhaust from manifold back....

glad to see that the ecu helped everything out...

currently waiting on cams and bigger injectors as well as my ecu from JWT...that should be here this week hopefully....next will be bigger throttle bodies, p/p intake and head, and HKS ALC(b/c i have an automatic)

unfortunately N/A headers wont fit my J because the steering column is in the way so im gong to have to have those fabbed...ill probably do them when im doing the port and polish...

definately interested in the finished product...

keep up the good work

Welp, I finally made it back out to the drag strip during Branson Z Fest last Friday. I was a little upset as I only got 5 passes before the shifter support bracket gave way. I really think I broke it and Paul finished it off on run 6 as he said he was having difficulty finding reverse after he tripped the staging lights. Anyway, I'm not super happy with the results. I could never quite get out of the hole. My 60 foots were ***. 2.34 being the best of the bunch. I red-lighted my last three runs, though all were really close to perfect. One just 0.0006 too soon. The car had some great MPH a couple passes (90 mph) and picked up a ton between the 1/8th and the 1/4 as high as 21mph. Here's a breakdown of the times. Fastest Time run by me was a 15.2124 @ 88.620 mph; Paul ran a 15.2XX @ 90 mph for the last run before we retired the car for the evening. I know it had a 14.7 in it, I was hoping to try again once it cooled down and the DA got a little better. I'm planning a trip to KCIR here in a few weeks; hopefully I can find it then. Here are all the slips for posterity’s sake.

haha those last 3 runs are pretty damn close to perfect reaction lol. must be because of that license plate ;P

You could definitely run 14.7 with a small 60 shot 'cause I did and I don't even have headers (but I do have wider tires and cooler temps). Hell you could have probably made it close to 15 with a few more practice runs! I'm going to be hitting the strip one last time before I swap just to put to rest some rumors around here about slow N/A's.

the guy in the right lane on the last run had stickier tires

I actually think he let out at the 1000ft or something weird. Look at the mph difference between the 1000ft and the 1/4, not a lot of gain there. Ozark is sort of odd in that the end of the track isn't really clearly marked. There is a line sort of, but you just look for the last sensor in the middle there and make sure you get by it or check out the guard rail on the left as at the end of it is the end of the track.

I know the car could've made it to the 14's if I would've been able to run it later in the day as the temperature cooled down and I got my bearings in the car a bit more. You have to remember, I've drag raced the Slicktop exactly twice. I've now had 10 total passes in it. 5 bone stock and these 5. I mean, hell, the first two runs, I tried to launch it like it was my TT... which didn't really work out as you can see with my pathetic 2.5 60 fts.

It'll get there.

What'd it run when it was stock? Was there a noticable difference in how it pulls now compared to when it was stock?

Keep in mind that the engine was on it's last leg as it blew to pieces the weekend after I went to the track (see page 1 of this thread) but my best pass was a 15.9 @ 84mph in bone stock trim. It's picked up ~6mph in the trap speed and should be down over a second in 1/4 mile time... so yes, it runs quite a bit better. It's smoother, has a better power band and doesn't feel like as much of a turd as it used to.

It's no TT, but it's the fastest NA Z32 I have ever driven or seen with my own two eyes. I'm still going on the project. We haven't even come close to seeing full bolt on potential of a NA-Z.

I haven't yet decided on which way I'm going to head next. The drivetrain is untouched. I'm still running the factory flywheel and driveshaft. There is some power to be had there. I haven't changed to lightened accessory pullys. I only have the UD crank pully. I am still using the factory fan clutch instead of electric fans. I have not touched timing, ignition or fuel.

There is still ~15-25hp in bolt ons there. Though I think my next major modification to the car is going to be suspension.

I know you've mentioned it before but any definite plans for cams or nitrous in the future? And would you ever consider any internal work such as bore and stroke or heads?

Not to speak for the man, but I doubt he's going to do that. It's not very cost effective and I think hes trying to see what an N/a can really do without going internal into the engine and stuff like that..

I think the scope was bolt on so a re-bore would be out of the question, but cams and high comp pistons would be a possibility I suppose.

WHen I put my one-piece driveshaft on it was like night and day in terms of putting the power to the ground -- never thought a driveshaft would make that much of a difference in power transfer but it made a big difference. flywheel and electric fan is where i'd go for now as they're both relatively easy and cost effective and have been known to give good results.

I just watched your dyno vid and lmao, "what boost are you running?" "Zero". Read the plates *****!!! haha

Anyways I was wondering if you ever pulled off the dampers on the subframe and trans mount? They are pretty heavy so I pulled mine off. I don't know of the ill vibration effects, I never got to drive the car with them on. All together the 3 of them should weigh over 10 lbs, maybe even more.

Finally got my new shifter support bracket in this week. I ended up co-driving with Jared at Autocross last Sunday which was quite a treat, his car is absolutely great. I can't wait for the suspension portion of the Project Slicktop show later this year, it's going to be great. I thought I'd throw a couple pictures up of the broken and new SSB install. Ow. From the underside. Comparison from the top Comparison from the bottom All ready for my next trip to the drag strip.

I'm getting tired of spending money.

There is a ton of stuff that I still need to do and I need to get on it pronto.

My shift knob moves very freely in neutral, is my SSB broken??

not necessarly, Its usually just the shifter bushings that needs to be changed, the oem ones doesnt last as long, get like an after market one... but its not that hard to check if thats the case or not...

Just wondering if you saw this post I made about those counter-weights. I didn't notice any effects while driving mine but then again, I have only driven without them. lol I figured since you stripped the interior these won't make any difference to you whether they be on the car or not. I would weigh them but I threw mine in the recycle bin.
