Just had to post this. May take awhile on dial-up (lots of pics). All it needs is a 240Z next to the Porsche. dream garage?

Great pic Carl! Except for the muscles it actually looks like Bill! MIchael

Oh and one more thing maybe a little more applicable to the discussion. I found this chart while doing my own research for a SU setup on my 210 (still working on that by the way). Anyway, this could be helpful. The 240Z carbs are 1-3/4". According to this triples would work best on 2L-4L - which fits the Z engines nicely. I got that here: clicky

Another triple setup for you guys! (I have no clue if this is real or not! My guess is not....) And anyway, there are probably more than 3 - maybe 6? Michael

Zspecialties.com sells a heater/fan that mounts in the corner of the window. But to work your original circuit has to be working to power it. defroster fan

Here are a few shots I pulled from the show. Turns out the white Cherry HB that sold on Ebay is Jesse's personal car. I don't know where the yellow one came from. They didn't use any of the 350Z's suspension because it was too wide. The front is from the HB and the rear came from a datsun pick-up. I guess over all it was pretty cool though I would have rather seen it done right - not a hack job like the MG guys do all the time. michael

A friend recorded it for me. PM me if you want to see it and don't have access to cable. I haven't seen it yet but I'll pick up the dvd this weekend. Michael

Thanks Bruce, I've sent you a PM. Oh and just to put a little bit of Z content back into this thread, I found some nice ram pipes that will work on the Z carbs. aptfast.com is a site for British cars but since the HS6 SU's are equivalent to the Hitachi SU's many of the parts there will interchange. Here's a pic of the HS6 Ram pipes at $32 each or so. They also have several filters available.

Thanks Victor. I haven't seen any 510's with 46's but I was wondering if they went to the larger ones later. Looks like they didn't. Bruce, do you know if Ztherapy has an A series dual "SU" manifold? There are 2 different ones - I need the later one with the oval head ports. It should be for 38mm carbs. Also there is a "cross-flow" manifold made by Lynx in Australia but I'm having trouble getting info on that (mainly the shape of the head ports). It's designed to fit HS4 SU's which are used on Mini's, MGs and other British cars. But I think the bolt pattern is the same for the 38mm Hitachi SUs but I'm not sure yet - still looking for info on that. I know the HS4's have 2 bolts per carb, 3" centers at 45 degrees. Does that sound like a Hitachi 38mm bolt pattern? Thanks for the help Michael

Worse for me are the bolts that attach the front fenders to the chassis down at the bottom near the doors. They're not hard to reach but they're always rusted through and snap off. Removing the broken off screw is the really hard part because it's very close to the floor and you have to work upside down. Implementing Escanlon's drainage system shoudl fix that though.

Well I may have found what I really needed. There were 2 different sized Hitachi "SU" carbs - 1.5" bore and 1.75". The 1.75" (or 46mm) carbs were used on the 2.0L Roadster and the 240Zs. The 1.5" (38mm) bore ones were used on early Roadsters, 510's, and the 1200GX which is the one I'm interested in. So basically the Z carbs I have won't bolt right up to the manifold I was hoping to use them with because the manifold bore is smaller. There are other differences betweem models that i haven't quite figured out yet. Also the size comes right out of the part number: HJG46W is 46mm etc. I'm still not 100% whether or not the later 510s moved to the 46mm bore later. Anyone know of any other Datsuns that used Hitachi "SU"s? Michael

Thanks for the pics Chino, Michael

Could someone attach a pic? I can't get the site to load. michael

Thanks Bruce. When I figure out what questions to ask I'll do that. I'm just getting into it so I'd probably just waste his time at this point. Michael

Here's the thread Chris mentioned: clicky I just did some searching for a manifold. Z Specialties quoted a price almost 9X what I got elsewhere ($175 vs. $20). Both used parts, similar condition. Maybe it was a fluke, I don't know. But anyway shop around before you buy.

Hi Chris, I'm not necessarily looking for Nissan P/N's, more the Hitachi P/N's like the one you just listed. So far we have info from the '71 and '72 FSM, so I was wondering if there was any difference in '70 model. But if I had been paying closer attention I woudl have noticed that ChrisA may have already answered that when he posted that his number is "up to 8/71", like you just said. I guess I missed that. But to be sure I would like to compare the spec details in the '70 FSM. Now as for why I'm doing this: I'm trying to figure out how the various "SU" type carbs differ and what parts interchange. I'm not only looking at the Z carbs, but also Roadster, 510, 210 "GX" carbs, and any others I can find. Once I have the specs I'll go looking for pics to see if there are visual differences to match. Ztherapy's site is a good place to start for that, but unfortunately they just don't link the pics up to P/N's. The reason is I'd like to use my Z carbs on my other dat, but don't know if the SU's interchange. While I'm at it I might as well gather together as much useful info as possible to fill in more pieces of the puzzle. Michael
