I cannot comment on that setup, but most guys stateside who actually do run a diff pump setup will use something like this with a small mocal or setrab cooler, similar in size to yours pictured. : https://www.pegasusautoracing.com/productdetails.asp?RecID=156 Depending on HP, etc, differential temps are a legitimate concern, even during 1/2 hour sessions. My memory is a bit hazy but I was seeing temps above 250 degrees prior to the pump. -
Apologies for dragging up such an old thread but this was the only applicable one I could find via a search here and thought I'd share. I plan on running a GPS speedometer as well, and was fully prepared to machine something up but on a whim image searched "datsun speedometer pinion delete plug" and found a match: https://zcardepot.com/products/transmission-pinion-gear-plug-delete-racing-oem?srsltid=AfmBOoqKAdugm1tF7u0EpsepQLggtB1_N4C0VGzhN7Azlut4rc0esj0F As well as here: https://datnissparts.com/rwd-speedometer-drive-pinion-delete-plug-32707-aa000-replaces-nla-99996-c3040/ It's a Genuine Nissan part, p/n 32707-AA000 with a long compatibility list of boxes - can confirm fitment on a 71C tail housing.

View Advert N36 Manifolds The infamous N36 manifolds!! I intended to use these for my current project, but I came into another N36 set and thought I'd put these up for sale as the threaded coolant tube ports are intact. Not the case with my others but I won't be needing them anyway. The two vacuum port tubes are busted off (circled in red), but most guys will drill and pipe plug them anyway as they were only for some nightmare vacuum apparatus on the 73/74 flattops. They would clean up nicely. I can sandblast & glass media blast them for an additional $100. Offered by: preith Date 11/20/2024 Price $100 Category Parts for Sale

View Advert Speedometer pinion, white/19 tooth New in box 19 tooth speedo [white] pinion. The p/n shows this to be the later ZX housing variety with the keyway 180 degrees out from the early ones. It's difficult to see through the NOS wrapper in my picture, but I can confirm the gear offset is as the one on the left in relation to the keyway. Make me an offer, I want it gone!

True but in that case they'd probably have a donor bellhousing available anyway. I'm looking/hoping to find a buyer interested the machine service wanting some convenience. Thanks for the well wishes.
-
Images added, apologies for the delay. Zed Head, the front cover needs to be sourced from the donor SX/C trans to accommodate the larger countershaft bearing. See pg3: https://zhome.com/ZCMnL/tech/240SX5spd/transmission.htm This will be going on ebay at some point but I'm not in any hurry to sell it at the moment.

View Advert Bellhousing for 240SX swap F4W71B Bellhousing for 240SX [FS5W71C] swap I had originally planned to use this for an auto->man conversion on a local Z I was going to buy, but the deal fell through so it's up for sale. Godzilla Raceworks is offering the machining service and charges $275 if you source the bellhousing through them - I'd be happy to drop ship mine to them direct to save you some shipping cost. https://www.godzillaraceworks.com/drivetrainfs5w71c/l-series-bellhousing-for-240sx-5-speed-swap A great in-depth write up detailing all steps can be found here: https://zhome.com/ZCMnL/tech/240SX5spd/transmission.htm Offered by: preith Date 08/09/2024 Price $100 Category Parts for Sale

View Advert 3 screw SU's on E88 intake, non-EGR balance tube, complete linkage Would like to sell complete as-is, but willing to remove the carbs & linkage for anyone needing a suitable core for a ZTherapy exchange, etc. The dashpots do have oil in them and are operable, but the butterflies are seized open. They were pulled off a complete L24 that was in a garage, but everything was sitting for a very long time. More than happy to box up and ship, however I will only entertain the contiguous 48.

I have an early 260 door you can have cheap. The outer skin is good but as with most doors the bottom seam is not optimal. Can snap some pics for you, PM me if interested.

Hello, late to the party but curious if anyone has some second hand info on the Moroso oil pan? This looks VERY close to the Nissan Comp one I had at one time, and it was around the same price circa 2000.... p/n 20976 https://www.moroso.com/oil-pan-datsun-nissan-l24-l26-l28-road-race-baffled20976/ EDIT/UPDATE: I reached out to Moroso, this is currently out of stock but will be available later this month or early the next.

Hello, long time no talk on this forum, dragging up a thread from the dead, even though my original pic is no longer visible, thought I'd post this car is now for sale: can be found here: https://hsrrace.com/classifieds/

Ouch!! Glad you made it out ok, thanks for sharing. Similar experience myself, not going as fast, but LF suspension failure, happened right as I nailed the brakes, tire rolled under the fender and immediately took me off the track driver's left (right hand turn approaching), on dry grass it seemingly did not slow down one bit... the worst feeling knowing you're just a passenger at that point. Didn't go airborne but went into an embankment. I had additional front bracing and the chassis was ok for the most part. Sore shoulders from the belts but that was it. The ego was bruised more than anything. Anyway the experience really cemented that the car could easily be a write off at any time.

Thanks, but just to clarify, some people might look at that link and wonder WTF we're doing, what I was really after is this, p/n 40-4185-075 in particular: http://ubmachine.com/balljointspins.html Which enables the use of a relatively common spherical bearing & housing, like these: http://ubmachine.com/monoballhousings.html May not be worth mentioning, but if there's enough room (depending on the brakes there most likely isn't on the s-30), you can also go with a "screw in" style ball joint with a threaded sleeve: http://www.speedwaymotors.com/Steel-Upper-Ball-Joint-Sleeve-K772-Style,2126.html http://www.speedwaymotors.com/Howe-Racing-22320S-1968-89-Chrysler-K772-Style-Upper-Ball-Joint-Steel,7935.html Also, to further complicate matters, it appears the K6024 ball joints have changed dimensions over the years, now requiring a taper ream to retrofit on an older truck for which it's originally intended. So if someone were to pick up an OEM unit off an old Chevy to compare, or perhaps the one linked above, they'd probably be more confused, see notes: http://www.speedwaymotors.com/Speedway-1963-71-Truck-K6024-Style-Upper-Ball-Joint,2245.html

My pleasure, and both, measured it first, ordered a stud (going with a monoball solution) and confirmed fitment once it arrived.
-
Thought I'd post this here in case there are some racers like myself who are looking to build tubular control arms, using US/domestic parts to retrofit, and I was unable to find this info elsewhere. Anyway, the OEM tapers of both the ball joints and tie rods are 7 degrees. The K772 and K6024 varieties WILL fit the 280z steering knuckles. I have personally confirmed this with the K6024's at least - the K772 p/n is used interchangeably in some cases, and shares the same stud dimensions with a .59" small end & .75" big end. The K727's will NOT work. Same taper, but the small end is already too large. I mention these as they seem to work with some of the later Nissans, and are also used extensively in other strut suspension cars. As for tie rods, the "pinto" variety seems to be the most popular amongst the circle track community. I've confirmed these studs will also fit the 280Z knuckles, but are a bit on the tight side and a light amount of taper reaming will be in order.

This car turned up again, this time on Ebay, now white: http://www.ebay.com/itm/Vintage-Datsun-Z-Race-Car-SCCA-HSR-SVRA-Road-Race-/271766724560?forcerrptr=true&hash=item3f468f1fd0&item=271766724560&pt=Race_Cars_Not_Street_Legal_

Very cool! I had completely forgotten about your old car getting tore up and agreed with the previous poster, a blast from the past! Great to see you're getting back out there.

It's a custom build from the ground up using commonly available circle track stuff - for the most part the norm here in the States for the SCCA GT cars. The rules are written to promote that type of construction too, even imposing a 2.5% weight penalty for IRS builds after 1990. The original idea (post '90) was to create a flexible platform from which one could easily update to various manufacturer engines and/or body styles, even switching marques, but it never really took off. Regardless it's still an exhilarating drive, with good brakes and low weight - typically under 2k pounds. You'd think the live axle wouldn't perform too well, but it does surprisingly. Operating costs are relatively cheap in comparison to other 'spec' classes as well.

I know it's not a Z, but a Nissan nonetheless and one could convert to an L-series under the current ruleset if they were so inclined. Anyway, an insane deal, I came very, very close to pulling the trigger on this but passed due to various reasons. The owner started out in the 40's from what I hear and is now down to 20k, including the trailer and all spares - you can't get a spec miata for less than that! Unfortunately he's lacking on the pics (however available upon request) but it's all professionally done, alot of trick stuff on there including a Saenz dog ring box which alone would probably go for about $3k used, here's a vid of a Bimmer with the same box: You probably won't find a better deal any time soon, here's his Ebay ad: GT3 1991 Nissan 240 SX 89 scca National Race Wins | eBay

Interesting history on Don's car too, when the SCCA first classed the 240/260 in EP ('98?), Sportscar (SCCA's publication) featured the construction of that car. Was quite exciting to finally see a new tub build which wasn't an IT car, no offense to the IT guys out there.
