should be able to google the blow through requirements. would be pretty standard, i'd be finding someone who'd tune it and ask what's needed. first google result i found for the carby was on a datsun forum. plastic float is mentioned, i don't recall ever hearing about one, but google found this for Me https://www.ebay.com.au/itm/202106654779?srsltid=AfmBOorpSCKBVuVo4LCfd_3xeI4T5NFzXkllCr9Ns4kc__Jnd7WYXu69 first post mentioning the 34ADM below (not much in it really) http://datsun1200.com/modules/newbb/viewtopic.php?post_id=414372

the GEMINI owners have used the falcon 34ADM for 20+ years, the Carby hat blow through set up is on ebay. LINK HERE if you find the same one on turbogemini .com, i've heard they aren't good at replying to emails or maybe not at all. so i'd choose the ebay option if needed for buyer protection. I don't recall a blow through falcon any time in the last 10yrs or so, but there's people doing gemini turbo with the falcon carby still and the also the cortina carby which is different but similar bolt pattern on the top of the carby. if you want to do it on the cheap and have fabricator skills, the LPG to Impco 300A adaptor has been cut off and 3" alloy tube welded to it, making a similar carby base to center bolt as below

I'm fairly sure the gearbox crossmember mounting points are wider on the XA (XB XC XD also same) I only assume this due to i think i've had both and one didn't fit. @Thom may know for certain.

at least it's not the AU one that's made of the crappiest plastic it crumbles as soon as you look at it (when it's this old) that said, they can still be cracked on XF, probably Qld climate would be more of an issue. XD and XE had rubber hoses that fell apart instead, so not sure what i'd prefer of the x series type.

@Mick.G here's a link to autobarn for the expensive one at autobarn.. (call them to be sure they have it before going down there i'd say) https://autobarn.com.au/ab/Autobarn-Category/Shop-our-Full-Range-by-Brand-at-Autobarn/Kilkenny/Kilkenny-Castings-To-Suit-Ford-Adaptor-[TBi]-Vacuum-Tree---KC137/p/SP66052?srsltid=AfmBOopr1HxNKshSCbhONTv6N4p97u12iidt1foW-AjsPSac5-3jXS5C I'm fairly sure there's cheaper versions with just the brake booster outlet, and one other vacuum outlet for heater etc, you could then T piece that into 2 spots if needed.

this one is sold, but @SPArKy_Dave may know if anyone stocks them anymore. https://www.justparts.com.au/parts-for-sale/ford-falcon-xe-4-1l-manifold-vacuum-outlet-2-port/JPW3972384

I've never bought from this place, just googled falcon XF vacuum tree ( one with the brake booster hose like yours has one bigger outlet ) https://srpauto.com.au/ford-parts/engine/manifold-fitting-brass-xc-falcon/

an exa turbo on a 1.8litre revving to say 6000rpm ish probably at 7psi is probably comparable to a crossflow on 4psi revving to 4000 ish .. is probably how they came to do those types of kits, they'd been a big low/mid range boost and not be too taxing on the stock drivetrain or require brake upgrades most likely. if they wanted to make power, they'd have needed different everything

the only memory i've seen of a pulsar turbo, is i'm fairly sure the 8 second 1/4 mile gemini was using one or their 9 second street gemini uses one at 40+ psi. (i have a feeling the 8 second gemini is running something different now, but not 100% sure) there really isn't many active members here anymore, and most aren't into turbos/boost anyway. you'd probably have a better response asking on a facebook group and filtering out all the troll comments.

no, it won't have a spigot bearing on an auto to deal with, but you should do the welsh plug on the back of the engine while the gearbox is off. (i dont' know for sure if it's got one , but i assume so) cant help with the rear main seal, haven't done windsor ones.

I'm not familiar with the fan issues other than I've read that being 20+ years old they can be dead from age/wear now. so testing them individually or checking the wiring would be an easy starting point. water leaks can be tricky to track down, a tip i was told decades ago was to puff flour around suspect places and it will be washed off if there is a leak. don't rule out water doing the capillary action of running down a wire, bonnet cable, etc if the grommet is cracked or just running down the firewall into the brake pedal hole etc (shouldn't but things like that are possible) also the door seals can be surprising for a leak source, as with windscreen seals. the flour test is probably worth doing if you have a suspect spot for leaks. the air vent is pretty tall, there'd need to be a lot of water in the plenum if it was to overflow that, and if it's been repaired in the plenum they should have seam sealed it otherwise. check the plenum isn't full of water due to blocked drains first, that's an easy test also

@Thom any thoughts on VCT heads, AU tickford heads and the XG head above? is the head even a restriction with a stock ish cam?

there's certain underdash units they used to refer to as KNEE FREEZE air con, because the vents just pointed straight at knees. i was going to fit one to My transit van (1980 model i sold ages ago now) but make a front panel with ducting up higher. so something to think about when looking for one, is if you can get outlets to point where you want it to. also, don't be tempted to use say an XF air con pump that likely bolts on, there's a Sanden unit that's much much more reliable that would be the go if possible. @SPArKy_Dave might have some ideas for air con if you are lucky.

give your 250 hater mates a shifter and say you've got 5 minutes to replace the starter motor.. (it's that easy) alternator is probably 5 minutes on a non air con XD 250... they got harder with air con fitted though. try those jobs on an XG and you'll hate your life choices lol. don't bother proving other people wrong, with large sums of money almost anything is possible.. just build your engine to behave how you want to drive it. you'll be hating the 13s choice if you think it's too noisy, uses too much fuel , can't cruise on 100kmh for hours etc if you only get to a drag strip once or twice ever.

@SPArKy_Dave Tassie based, be expensive to post to mainland for changeover surely? or do Repco do them.
