Boosted motors use cams designed for them. Don't use an NA cam for a turbo motor.

Look at the air filter on your daily driver. Want that stuff sticking to your cylinder bores?

Wrong forum...sorry.

If anyone is looking for the correct color, here's my "solution": After searching for a decent price on 240z rear tails lights, I found a set, cleaned them up and installed. Look great. Installing these on a 260 or 280 requires cutting some metal and getting new gaskets (or making your own which I did). After looking at many different pictures to deterime the original color for the tail light housings I found "Dupli-Color" at Autozone. The "Duplicates Original Honda colors" appears to match the original Datsun color right on or at least close enough for me. Any my build: http://forums.hybridz.org/topic/103487-san-antonio-31l-z/page-3?do=findComment&comment=1078715

Obi-Wan came back to Luke in the Trench with a phrase....one I paraphrased and used once with a co-worker long distance..."Trust your instruments, Tim!" In the heat of the moment it gets easy to overthink things. Since that time, now close to 20 years ago...Tim has called me several times laughing as he was out on a site troubleshooting, getting frustrated, at the end of his rope exasperated and the "I hear your voice from that damn phone call at XYZ 'Tim, trust your instruments'...and I just go back to the troubleshooting chart, MAKE SURE everything is set up like it says, and I find the problem!" It's a joke between us now, it was kind of a joke then...but in humour lies underlying truth...which is why it's funny. In 30 years of NOT trying to outthink the guys who made it, and just listening to their advice...it hasn't steered me wrong yet. And infecting others with that mindset has made their lives easier as well! "Connor, use the FSM! Trust your instruments." Tony, I've read many of your posts. Maybe most of them. Above is one of your best. Yes, I was over the top. It was a quick response to what I mentioned before, the "go check xenon" stamp response. Really got tired of it over on Zcar.com. Saw it too many times. One particular problem came to mind when I posted that response. I had a problem that I couldn't find a solution in the FSM. Car would run fine and start choking off after about 30 minutes. Let the car sit for 5 minutes and I could get it home. That was 5-7 years ago. I went through the FSM back them and couldn't find a solution to the problem. What was the problem? Car acts like its out of fuel after 30 minutes. Let it sit and I can limp it home. Did I guess the problem/solution correctly? Yes. Did I find it in the FSM after looking? No. Right now I just went through my hard copy FSM for the early 74 260z. As it sits in front of me, the solution is on page EF-11. Under "Condition" it says: " Fuel pump fails to discharge sufficient flow." "Probable cause:Clogged Filter". Bingo....Well, its not so simple. To the novice mechanic or wanna be mechanic, which I was at the time, I had no idea the; "Fuel pump fails to discharge sufficient flow" was the problem. Actual problem could have been a bad coil, bad plug wires, degraded wiring from the steering column on down, bad fuel pump and ok filter, battery terminal corrosion....list goes on. Would FSM be a better reference if it addressed the RESULTS of a clogged filter upon the fine car? Hell yes. So, is the FSM perfect for the novice? Nope. Not at all. Is everyone here a competent mechanic? Nope. Am I? Nope...... steve

T, I knew once I posted that someone (probably you....!) would torch me for it. I hear ya but I've been in the same situation before and been frustrated with the manual. Yes, tracing wires is troubleshooting. You are correct. I just get tired of people responding to other peoples problems with the here: "go to Xenon and read the manual". BTW, you're much better than the FSM!

The FSM provides little, to no troubleshooting or insight into solving problems. Besides how to rebuild items, disassemble parts and track every single part or electical wire, its not useful for these types of problems. If it was, the above "answer" would solve 90% of the posts here.......

Nice job Tony.

If anyone needs 40 pump jets here is a good deal: http://www.ebay.com/itm/WEBER-DCOE-PUMP-JETS-SIZE-40-SIX-GOOD-USED-/151066901452?pt=Motors_Car_Truck_Parts_Accessories&hash=item232c49fbcc&vxp=mtr

Test the compression, good place to start.

Btw, how the hell do I use this? Am I suppose to open up the diaphragm to allow more air through? Obviously, if I place it over the air horn the motor dies...The only air traveling through is from the tiny hole. Thanks steve

Good idea. I can see that....Yes, I have 18s with brass floats as well. (I JB'd mine..Ha!) See how long that lasts. I expect seeing the broken off piece laying in the fuel bowl soon. steve

Holy crap. I broke mine today too!! I was looking at all the weber retailers and didn't see any replacement tops. They gotta sell them...No way we need to buy another carb. What timing are you running? Initial and full? steve

Webers are coming along. Just bought 36mm Chokes. Better low end power and smoother running engine. Most of the tuning issue are posted on the tripple webers forum page. I ran a compression test for the 1st time. Pretty pleased. #6 is certainly strong for some reason. Have about 150 miles on the motor. #1:170lbs 2: 166 3: 175 4: 168 5: 175 6: 200 steve

Great. Did you think the car drove smoother and rev'd more freely with the 36s?. I have the same bog under 2,500rpm WOT. That was the result on my 3.1L. One jetting difference is I'm running 160 air correctors. Think I should be running something like 185s? Here http://joltfreak.tripod.com/id28.html It suggest main jet + 50 for air corrector size. I'm running 145 mains so air corrector would be in the 195 range. steve

Let us know how those 195s do....I'm currently running the 160s. Need to purchase the wideband. Maybe stupid question but here goes....Since I don't have welding unit is it possible that JB Welding the sensor bung would work??? Too much heat? If not I can get it welding in. Just a (dumb) thought.

Yeah, that's strange. Certainly cheaper than the $23 bucks on their site. My cam is .480 lift and 274 degree. ss

Awesome!! Whats your engine build? Unfortunately, I'm still getting traction on smaller tires..... Did you post it previously?

Best way to describe would be a free-er reving smoother engine with another 10-15hp. For example, in 2nd gear under hard acceleration I get more hood lift with the 36s. The motor feels stronger and more aggressive. Funny thing is from 5K on it feels about the same. Little smoother but not more powerful. I was thinking the top end would see the greatest difference. Also didn't expect the motor to run smoother either.

Well, I haven't fully researched the jetting set up. Actually, I told the guys at Top End my complete motor specs and they suggested the jets. I do have 55F11 idle jets and F2 E-tubes on hand. What would you suggest?

I drove it some more this morning. It certainly has more power and actually runs smoother but, it will fall flat if I go WOT below 2,500 rpms. Other than that its a better running weekend car. I still need to do more tuning. Only have the carbs kinda sync'd at this point. Motor is under 100 miles and need to re adjust the valves as well. Head had a valve job so, this certainly is not definitive at this point. Steve

Ya, I saw your chart a few weeks ago. Assuming the tuning goes well with the 36s I'll set you up with the 34s. steve

T-Bone, Just got the 36s. Off Ebay for thirty bucks from a guy in Alaska, of all places. "Came off a racecar".....I think I can count the number of racecars in Alaska on one hand. Anyway, only blasted around the neighborhood for 5 minutes. Only time I had but great power! Very, very noticeable. I'll make a longer drive tomorrow.............

No Dyno plans but certainly 1/4 mile. ss
