Undefeated

Ok guys, lets chat about the current bolt on self learning EFI 2 barrel ( or 4 barrel ) ,yes bolt on carb style EFi kits from FiTech and Holley that are out there now. 1st) no I don’t feel like bolting up and connecting crank angle sensors , soldering crap together and everything else...then doing dyno time with a laptop, , selecting injectors.. and so on.. if I wanted to spend 5k+ I’d drop in a 8! ( Or I think I’d just smash in a 2nd hand Barra for complexity ). This basic style of EFI is a simple $800-$900, it’s bolt on and go, this seams a ok upgrade on top of what I got, it comes with a hand controller to fine tune it a little. Let’s just pretend I want to keep my old 250..as it is, sell my holleys, and just put a efi syle carb on as a replacement for the 350 Holley that’s currently there..keeping it as simple as possible.. this is a Carb replacement.. so I have a couple 350 holleys on the bench, and I’m running a redline tourqer manifold,Extractors and some sort of choppy cam.. (the compression hits my hand from a metre away so it may have other mods..) .. frankly I don’t know what’s inside it, I just want something that will idle clean and runs ok.. So for me, I’d rather just bolt down something that goes well, And it has to do that on top of what I currently have..( whatever that is..) I want it to start cold nice and go ok.. simple with no smell of fuel, popping or rough running.. So, before I waste another $ , I’m thinking just selling my 350 holleys for $100 each on gumtree, then looking at the possibility of just bolting down and running one of these self tuning EFI style 2 barrel carbs from FiTech or Holley on the Redline manifold.. has as anybody run one yet on a 250? give me your opinions..(and who knows, I may even try run a std style air cleaner housing just to mess around with people that little bit more

After looking at some options I decided to go with the Holley Sniper EFI kit.. for those unfamiliar with these this is the new Holley Carb replacement system. There’s a bunch of Videos on YouTube about the sniper EFi, but a quick run down: yes they can be boosted, they self learn, they can control ignition too, they are a touch screen like your IPhone.. for deeper tuning they plug into your laptop and once there can be tuned even more. I spoke to Holley directly and the 2brl kit was the suggested option. It’s good for it’s 350hp and flows 500cfm.. ( they can go more boosted) , They also informed me that they havnt sent the 2barrel version to Australia yet.. so this is the 1st one! In this thread I will try to go through my process of installing it.. some say it’s a 2 hour job to install and drive.. I never work that quick.

Yes it’s going well .. wonder what kens thinking? Think we went to school together? Or that yellow 302 Mazda from the older brother rings a bell from the 90s at saint patty’s blktwn? Great, but show us some insight on how these times were achieved with the Bonnet up, either way.. single 4brl??

So here’s another cool feature that can plug into with the Holley sniper EFI.. its obvious holleys new roll out has been well thought out.

Still playing with other aspects of the car before installing. in this video theres Some intresting aspects, it’s a Blo Thru Turbo 6cyl..video shows some set up including the return line dumping into the filler hose.

I’m going to put this link in here for future reference.

I’m trying to figure all that atm.. which dissy to run. (Side note: yes I’m aware of a std Barra that recently run 350hp with just a carb and cams here in QLD ..but im no drag racer, it’s intresting to see what may be out there for the future.) Back on topic: for ignition control , it’s going to have to come latter. here’s the video of the Holley tech rep showing Phasing and dwell.. atm I’m scratching my head TBH as to what Distributor to run.. EST , TFI. I’m checking on Holley Sniper forums and seeing what USA Ford guys are doing, I will probably contact Holley directly and put it to them. In years to come people can look at this...hindsight makes a expert.

Well finally that Walbro fuel pump arrived today with the mounting kit, so now it’s time to start working on the car.

That sounds like a cool way to go.. I havnt fitted it in yet, still waiting on the fuel pump

Nothing wrong with a belt driven dizzy, the old v8 928 Porsche runs a dual distributor set up that’s belt driven...

Exactly, the big filler hose gets a simple plumb into it ,and the return squirts in there. (nothing to do with the tank venting /charcoal system) the complex part for me atm is working out what air cleaner system to run, and how I’d like this motor to look, I like the idea of a blow thru style carb hat connected to a k&N pod or cold air box, but a nice air filter looks good too...and to be making sure I’ve got the right dizzy and Holley connector with plugs and leads to run programable ingnition.. it’s recomended to just do the 4 wire hook up first.. so a lot of guys don’t run the ignition side of Sniper EFi I noticed..( if not controlling timing, that’s a simple 4 wire hook up) and whats up with everybody bagging REDLINE??! This is a good little Aussie company success story.. who has supported the crossflow motor and others, and I’m happy to have there products on my old car..changing to any manifold is not going to net much on a street motor, the efi should atomise better than a 40yo old carb. .https://www.redlineauto.com.au/t-about.aspx

It’s a Return line system.. same as normal EFI..the return line runs back to the tank. It runs a reg inside the Carb so no reg required to run it NA. there is many instal vids on YouTube, as I do each part will link a video on that subject.

It’s a return line system.. the feed runs into the fuel tank, above the tank. ( where you pump fuel when you fill up there is a large hose between the tank and your rear licence plate.. the return hose plumbs into that)

Thanks Ando, very goodinfo. I probably will run it a little fat ( no “Hollywood runs” here) I remember talking to ultra flow 15years back , It was made for even flow, I think he wanted about $650 back then. I’m interested to try different manifolds down the road.. ATM I have yet to figure out the best way to intergrate the sniper ignition timing control..EST /TFI...Probably the XF distributor and I think , I need to order a specific connector with all that. It’s a latter addition.

So last piece of the puzzle before installing, I decided to do my own fuel system. I believe the fuel pump Holley normally supplied with Sniper are Walbro pumps.. Looking at what others have done, and for a good budget pump , I ordered the Walbro GSL392 ( 255) and in-line mounting kit.

I’ve spoken with them as I’ve had a few of there manifolds through in both 2brl and 4brl versions..but that’s the thing, as a starting point there’s a lot of 250 out there with the Redline manifold. I think I will hold off on another manifold ATM, because I may use this Holley Sniper EFi to simplify fitting in a much newer motor, and that may require a Aussie Speed manifold.

I would do it if you can before they put Tax on everything

It’s just your basic 250 crossflow Xe 4sp manual with 126klms on the clock.. The engine has a redline tourqer manifold and extractors I’m led to believe it has a mild cam in it too. Engine is in good condition. other than the Sniper Efi, I have a set of AU thermo fans for it and yes the Sniper EFI controls fans to, so no need to buy a fan controller ki..it may also be able to control a EWP.. This car purpose is to be a classic daily driver atm but there should be some scope for future development.

I’d keep the crossflow and build for tourqe.

Motivator NHM 550 extractors off my XE.. this my new build , it’s as old as the hills and hasn’t seen the streets for 20years..(126k the clock I think is genuine, there’s no rust in the car, but it’s body has been bumped around a bit) Anyway, I pulled these old Motivator extractors off, they look mandrel bent, no kinks..even turns, not bad I guess..better than the genie press bent stuff I’ve seen.. 6 -3-2 design I think.. merged into a 2 1/2” pipe. I pulled them off to go to my ceremic coater with some other stuff on this years build, and I noticed there’s a dual pattern bolting flange. Question is whats the other motor they fit? I’m guessing it’s the Iron head, but only other thing I can think off is the XG 4.0. Are the port spacing the same on the 250 crossflow and 4.0 OHC exhausts, Bottom bolts the same but the top has 2 different bolt flanges..? The iron head was different wasn’t it? Iron head or OHC 4.0?? xg is all I can think if it’s not that heavy old iron head? Ran the part number and nothing on google.. I think Motivator Extractors was Lukey or Walker.. I can’t even find any info on that..one person said there pacemaker.. stummped atm , they look ok, but just curious before I send this lot off for some shinny coating.

Further Update: grew up in the States and have family there so im all sorted now..got a good deal! 2 barrel sniper master kit is sorted and on way.. I will do a thread on OZfalcon to show it’s fit up. I could have gone the 4 barrel version, but for what I’m doing there’s no point.. the flow is around 500cfm from a 2 barrel Sniper and I suspect it may atomise better on a mild 4.0 or 4.1. im keeping the Redline Tourqer manifold for the moment to compare against others at a latter date.

Well as a update: im about try order this , but keep running into import charges that are adding a few 100 to the cost.. Looking at all options from Holley and FiTech, yet still getting slugged with import charges.. checking out govt websites I shouldn’t have to pay a import charge on under 1k total including postage .. So hunting hard to try find the best deal.. of course I’d rather Holley but those import charges add another 300+ I’d rather not deal with.. at the end of the day it’s not that cheap, especially thanks to the import charges..hmmmm.. I will keep hunting ,but any tips on buying?

A bit further back it was mentioned about the tool ( it’s a square block) to wind in the calliper, this is available from super cheap for a $20 or so.. I set caliper up with a gclamp or vice from memory to hold it , and the tool did the job winding it in, I put a extension bar into the square with a ratchet... there a universal thing designed to fit many Calipers. just wanted to add some input..

Go onto the SuerCheap website, they sell tyres and give reviews.. the prices are cheaper than tyre shops for exact same tyre.

Yes I’ve read that too.. this is new stuff so we are all on the ground floor.. this isn’t the McGee injection we tried ( my older brother tried that stuff) on in the 80s, as Steve Morris stated “ this IS Holleys carb replacement!”
