19 tooth white gear is for 3.9

Fast Idle is on balance tube. Part in question would have been connected to emissions device, dash pot? Anyway, here is a photo of what it use to be connected to. - Mike

I've used the 3M kit on two cars with very good results. No swirl marks when it was done and the lenses were clear.

I've been doing the EFI learning curve as well for my 240. Patton Machine uses low impedance GM TBI injectors and you use existing SU carb bodies, manifold, throttle linkage, and air filter housing. You just drop his adapter in place of the piston and notch the domes for fuel supply if you want to keep the domes on with hidden injectors. Stock appearance with EFI technology and it can be switched back to carbs. Obviously have to change fuel pump with any carb to EFI conversion. Jenvey, TWM, Weber, Extrudabody all have throttle bodies that can be mounted on triple carb intakes from Mikuni or Weber DCOE style carbs. Extrudabody and TWM both have options for using SU carb intakes with Dual TBIs. Both use Bosch style injectors. Of course you could also go with a 280 EFI manifold and an aftermarket EFI ECU. I've narrowed my choices down to PattonMachine adapters and Extrudabody dual TBIs. With these you only need two injectors. Both use existing SU manifolds that flow plenty of air. Looking at going with MicroSquirt ECU (MegaSquirt's little brother) since its already built, small weather resistant case, it can run 2 low impedance injectors, ignition control all for $400(not including sensors and other hardware). Caen Fred is running Patton Machine adapters on his 240z - Mike

With 4 screws the nozzle can be adjusted by loosening nut underneath the carb. If you take the needle from the front carb and place it in the rear, does it still stick? - Mike

If you are going with new springs, Isky has a "268/Mechanical" grind that has very good street manners. Adv Duration: 268 .050 duration: 232 Lift: .480, actual installed lift on my motor was .497 intake open/close: 23/65 exhaust close/open: 65/23 overlap: 46 LSA 111 It is very similar to the Isky L-480, except the overlap is less, 46 versus 62, and the LSA is 111, instead of 109. .050 duration matches that of the L-480. - Mike

Those that have bought this aluminum radiator, did you go 2 or 3 rows on the core and could you post some dimensions on how thick the core measures. Thanks, - Mike

Since your in Alexandria, I would try Banzai Motorworks in Upper Marlboro, MD which is near Andrews AFB. Also Eiji of Datsun Spirit is in Manassas. - Mike

I have been in contact with Dave Patten with FutoFab on having molds made to make their 240Z BRE style spook fully enclosed. The ducts will be made in a similar fashion to the 510 BRE style spook, bonded, not overlapped. "Here is a little background on FutoFab. We purchased all of Joe Vondrechek’s QuikSkins molds several years back. QuikSkins parts were held as being some of, if not the highest quality in Datsun 510 fiberglass components. Now, personally I am not a composites fabricator; my expertise is in rollcage/racecar fabrication which I have been doing for local racers since the late 80’s. These molds sat in storage virtually unused with the intent that I would someday “learn the trade”. As we all know for some things there never seems to be enough time to get them done. Learning composite fabrication was one of those things for me. FutoFab, not having the internal expertise or proper facilities, decided that we would team with Composite Component Engineering to make our 510 composite pieces. CCE is a full time racecar composites shop, specializing in short run production parts, one off component fabrication and carbon fiber restoration. The owner Steve Maxwell gained his experience as a composites fabricator working for Bob Akin Motorsports (IMSA GTP Porsche 962 Team owner and driver). CCE's now manufactures CF parts sold by HRP Racing and others. One of CCE's latest projects was the carbon fiber body panel restoration of a Spice GTP car. They restored and in some cases totally reconstructed over 30 individual body panels to return the car to trophy winning vintage race quality." - Dave Patten The attached pics are of the 240Z BRE Spook in black gel coat. The new spooks will be an orange gel coat, not black, if you get the fiberglass version. The pricing is the same as what is currently listed on the FutoFab web site: "Orange Line" Gel Coat fiberglass w/ enclosed ducts - $135 + packaging/shipping Fiberglass/Epoxy w/enclosed duct $180 + packaging/shipping Carbon Fiber w/ enclosed ducts $225 + packaging/shipping These prices are comparable to MSA and their version is not fully enclosed. I need to get 2 additional orders for these spooks by Sunday October 11th. If there are at least 3 orders, including my order, then there will be no charge for having the molds created for the top of the duct. I don't know if he will be increasing the price for these in the future and I am not aware of any other vendors that currently sells a fully enclosed 240Z BRE style spook. If you are a willing buyer, please send me an email. Payment needs to be made directly to FutoFab on Monday October 12th through PayPal. I need to coordinate with Dave on who the buyers are before hand. Fabrication time is roughly 7 to 10 days after the order is placed. Thanks, - Mike

Racer Brown article is a great read on camshafts. Datsun camshafts & valve timing by Racer Brown Read it, take notes, read it again. If you want to cheat, jump to chapters 7 & 8 and he talks about selecting camshafts. I used the "weekend warrior" as a guide to getting Isky to do a regrind camshaft. There is alot to camshafts then just adv duration and lift. Schneider 290/495 with lobe seperation angle(LSA) of 106 is going to have a rougher idle then Isky 290/490 cam with LSA of 109. Both cams are going to have a rougher idle then a 270 duration cam. Decide on a cam for how you are going to drive most of the time, not an occassional track day or you can get a deal on it. One cam is not going to be perfect for street, autox, and the track. To me, 290 is too much duration for autox. To someone else, it may be perfect. - Mike

24F is for switching the positive to be closer to the engine and away from the inspection lid

Lowe's carries 3 in one motor oil for $2.37 I found it in the tool section with WD40 and PB Blaster

How about contacting Wolf Creek Racing and seeing what it would cost for them to rebuild the troubled carb or better yet, have all three carbs rebuilt? I'm guessing it will cost you less then buying another set of carbs. I wouldn't go from Mikunis to Webers - Mike

FYI The Datsun Comp is a 6-2 header, but the design allows for running duals all the way or allowing the end user to determine at what point they want to have the 2-1 collector placed. Placement of the collector close to the header or near the rear diff does make a difference. My memory is bad so I'm not going to guess which placement causes what changes. I just remember discussing this with someone involved in Datsun SCCA race engines and they tend to place the collector near the rear end and on a street the collector tends to be near the transmission - Mike
