angle iron. Drill the holes such that the rotisserie is dead center. Use grade 8 bolts for safety.

"SM" needles. They are made specifically for this issue. I had the same problem as you, changed to these, and no more problems. They give you more fuel up there. here is a link to some I quickly found on eBay for you. when installing the needle height, you want to use a straightedge to make sure the level is correct and not too far "in" before tightening.

Let me know how it goes. Please.

Update, please.

05-17-2025. Today I installed a light kit in the engine compartment and another inside the car. I got both from Amazon. I also went ahead and installed a "Green Filter" on my block breather tube. As soon as I tightened it, it crumpled the green part a tad. It would have been great if it had not done that, but oh well. Here are a few pics. Videos, click below.

05-10-2025. I did a lot of odds and ends today.....little things put off.....I just went around and fixed as I saw them. I used the clear PPF film over the carbon fiber on the inner fender as it was getting real ratty looking on the edges. I also cut some pieces, and put it on the 2 spots the seats are showing wear from being a big guy getting in and out of the car. Will they work on Vinyl? Not sure, but I need something there. Seams showing some cracks due to my poor bodywork skills, this seals them so I can just forget about it and enjoy the car.t Tuch up painting all over the place, then vacuuming....I guess you could call it spring cleaning. I went back to a novel way of richening up the carb a little....washers under the choke know to add fuel everywhere and buy add a washer at a time I have been able to make a lot of progress on getting it right. The other way would be to buy a richer needle, but this is easy, cheap, I already have the parts, and it works. In short it was just a nice sunny day and I got stuff done. I did take A LOT of pics, so the pics I will put on here.....it's pics heavy. so you are forewarned. Cheers and God bless.~Joe

05-07-2025. My custom ordered fender stickers came in. I covered them (and the rear stickers) with some PPF clear to make them permanent.

I imagine you will be saying Sayonara to the body for at least a year. Quicker than that you must have an "in" with the body and paint hop. Here's to hoping you get it back as soon as possible.

On mine, I also used the Z car Depot ones, I had a mobile welder install them.....basically he did what he could with them.....it seems the bend radius is not tight enough and so when welding you have to weld up that "gap? or relief cut, being thick gauge metal, it wouldn't be fun to beat it down flush.

05-02-2025. I got my shift knob with button. I got it from Speed Dawg Shift Knobs. Top notch shop. Shipped it very fast, well packaged and I even got a military discount. If you need a shift knob check this guy out! I got it installed, and all wired in to my Snow Performance Stage 1 Water/Methanol injection kit. I also got my Vacuum Block from Amazon, and got it all hooked up, so the vacuum needed for my Boost Gauge and J&S Safeguard is more professional. I also added a pic where you can see my passenger well is all cleaned up. Good day!

love the custom work. I installed an AutoPower race 4 point rollbar, and later had to cut out the straight across bar down low. I just HAD to recline the seat!! On the diagonal bar I put a piece of rollbar foam on to rest my head. I made it work.

it should, however some guys think out of the box and do their own work.

04-26-2025. Well, I was able to fix a few little things on the Z today, getting it more and more cleaned up. I ended up putting a stainless clamp around the turbo to manifold hose, as it was getting sucked in pretty bad from the pressures, this keeps it from doing that to a great extent. I let it idle and revved it a bit and I could see a real improvement. I developed a front tire rub again, which is weird as it was entirely done and good a long while ago, but it is what it is, so I was able to get that done, changed out the timing belt for a much better one, and ran the wiring from the shifter, through the boot and under the console down to the point where the connections are for the Water-Methanol injection.. It will be on a push button shift knob I ordered. The boost switch just wasn't working like I wanted. I want more control over it. I drilled a small hole at the top of my dash insert and installed a small amber light which when wired in, will let me know when the water/meth is on. I also took 2 video's, once of the finished engine idling, and a walk around. So 2 pics and 2 videos. Cheers! Videos (2) click below (14) Facebook

oh yeah, perfect size for teh engine. Thanks a lot for your help.

yeah, I'm happy with it. Thanks for all of your help.

No problem, have a blessed night Sir.

very nice. You don't happen to make a vacuum line distribution block do you? I have 3 items needing vacuum supply, and they don't like T's in the line.

do you have a pic of your Ace Hardware stopper? Thanks.

Just an addendum. Now DYNO is next. "4-22-2025. Things came into the right alignment today, and I was able to get the exhaust tied together at Bud's Muffler here in Colorado Springs, and get a final tune on the Z car. The exhaust threw all the tuning I had done before out the window. My pilot is now at 50, my needle is on the notch above the bottom groove, so more fuel, and 2 turns out on the air screw. washers are no longer under the choke, running just on the intended circuits. She is VERY quiet now, and the added backpressure seems to have made a difference, she acts better now. here are some pics and a walk around video of it all done. I would like to get a DYNO sometime. Now it's back to washing and cleaning and waxing, etc. pics follow. Cheers and God bless." Click below for video: (9) Facebook

UPDATE: Spool starts at 2600 RPM AND FULL SPOOL BY 2900-3000 RPM. Great turbo for a street Z car S30 IMHO.

ALL DONE, PROJECT LENGTH, 5 MONTHS, 20 DAYS. I WILL POST DYNO RESULTS HERE, OTHERWISE, THAT'S IT!~

UPDATE: she starts spooling around 2600 and fully spooled by 2900-3000 RPM. I will have to wait to see the dyno graph, but it seems to be pulling to 6K RPM no problem.

3 layers of insulation brake master hovers around 200 degrees F. No issues. Couple years when I bleed the system I will go to the Motul 600 degree F brake fluid.

04-21-2025 TURBO PROJECT UPDATE. Well she is done. A 5 month project and it fought me all the way, but she is drivable and just needs to go down and have the exhaust tied in.....but she is running and driving. The HSR carb, being a Motorcycle Carb has a very short throttle when used in a car. I have a 1 inch to maybe just short of 2 inches of travel, but I think it's more like 1.5 inches of travel. So, you have to ease into the power, if you just mash the throttle, it can overwhelm the setup. Granted, this is a hilly billy built, shade tree mechanic, DIY turbo setup. I started with a very dusty box of worn out crown turbo parts that I had to clean up and then order parts that would bolt together, and nothing ever went together like it was supposed to in my mind. I went with a Chinese T04/T3 Hybrid Turbo that I then sent off to the "G POP SHOP" to have them put carbon seals in it (mandatory on draw thru turbos) and go through it and make sure everything was good. I then came up with using the motorcycle carb after seeing other Z car builds other builds, even though they weren't turbocharged, but then finding out that Turbo Corvair guys were using them. My 2.9 stroker with a ported head needed a lot of fuel, even at my 6000 ft. altitude! Endless jet and needles changes, and then finally settling on a 240 main jet, a 45 pilot jet, a Y8 needle jet, a stock needle with the clip on the 2nd to last clip, 1 turn out of the air screw and still having a bit of fussiness, so I then thought out of the box....the choke circuit is a separate circuit. When idling, I pulled onthe choke and the engine got REAL happy! to I looked at the distance of the shaft when I pulled the choke knob. I then took 3 washers and ground them open and stuck them on the choke shaftand then pushed the knob down. Now I had a system where by I could, through trial and error remove a washer or "shim" one at a time to find the sweet spot! 1 washer seems to be it, although still a tad bit extra fuel at the top under wide open throttle. I can udjust some of the fuel out by adjsuting the accelerator pump to not pump during htat situation, which will lean it up and make it run even better, jsut more trial and error. I will fien tune it a bit and then take it and get it put on a syno jsut to see for fun what I have. It would be nice to think my homemade deal would give me 40 horsepower, but we won't know until DYNO day. I have added a few pics and 5 video's of driving the car. keep in mind, the exhaust is loud but you can really hear the turbo. Thanks for all the positive comments over the last 5 months.....and the few that told me "you're going to blow up the engine" ......."it won't work" .........."you're just going to destroy it"....."you are stupid, everyone knows draw through systems and carbs do not work." (even though Corvair guys and air cooled VW guys do it all the time, and were a huge source for info)...... .well, it worked so I guess you aren't as smart as you have led yourself to believe. Cheers! Pics and vid's (5) follow click below for video's. should be 5 total, one after another. If it doesn't work, PLEASE let me know. VIDEO link: (20+) Facebook

04-21-20205 UPDATE: I went ahead and dropped the needle, went down to a 45 pilot and increased the main jet to 230 from a 210. quick drive, starts and idles easy at 1.5 turns out on the pilot screw now, needle movement was too much, as soon as the throttle rolls into the needle, A/F ratio goes to 16/17 to 1 I managed to get through that and on to the main jet, instead of fall flat, now just pop and sputter....LEAN..... SO......I will richen the needle 1 slot, go from 230 main to 240 and see what happens. I lost the plastic washer under the clip for the needle and installed anyway, seems to have the effect of leaning it out 1 slot, I ordered some plastic washers for it, if they don't come in before I work on it again, will adjust needle and main and see what happens. I can't believe it finally idles on it's own. Once this is better then I can take it down and get the exhaust fixed. 99% done.
