Outback Jack 6,352 Posted December 4, 2020 Cheers Bear, and Gerg and Thom for your input.Much Appreciated. I wanted to do the block in my ute as its matching numbers but that will leave me with no transport, so looks like I might have to have the short block in the spares ute done.Only thing I'm worried about is its been sitting for 9 years without a head on it, under the spare ute bonnet.Sent from my S21 using Tapatalk Share this post Link to post Share on other sites

Au egas engines use better crank and rods than a standard petrol engine (also slightly higher comp, and an Ef xr6 head on an Au egas short nets 10:1 comp) Au engines can take a BA turbo crank and rods without machine work, Au rods are longer than e series with a hypertectic pistons (same advantage as using 3.3 rods in a 4.1 or 302 rods in a 351) a really nice Combo (what some of you will remember I had in my xh) is Au egas short motor, Ef xr6 head, ea cam, El intake with a set of extractors and a tune made 178 rwkw for less than $600<br /><br /> Hello Thom,Just been Scoureing your Threads on the SOHC 4.0. ?? Now if you managed to get 178 rwkw from those changes. How many rwkw/s would one get from a standard used old 4.0 sohc? Just trying to get an idea of contrast.

deankxf 20,864 Posted January 16, 2023 asking here, because i did a search for "dipstick" in this thread and it didn't come up. (hindsight, it might be "dip stick" anyway, What do you need to do with the dipstick tube if using an EF engine (had BBM) in an XG (using the log manifold) and you've thrown out the XG engine already.. to pillage the correct one. (asking for a mate, apparently it doesn't work with the log manifold) Share this post Link to post Share on other sites

(asking for a mate, apparently it doesn't work with the log manifold) That is correct, the dip sticks are different depending on intake, I think from memory (a 14 year old one at this point) a log dip stick can be used with a bbm but not the other way around, if being very careful you may be able to bend the bbm dip stick to fit the log manifold but some butchery may have to happen to the mounting bracket 1 deankxf reacted to this Share this post Link to post Share on other sites

Thom 6,704 Posted March 1, 2024 Here's an old video circa 2007 with my phone taped to the steering wheel running from zero to 180 kph (i was inventive back then) of my pick a part special 4.0 it made 144rwkw around this time, and it made 177 rwkw with a tune later on (video quality is representative of its time) it was in my xh ute with an ex taxi au short motor (from memory had more than 860,xxx ks), ef xr6 head (94 dt) ea cam, el bbm intake, super cat extractors, crow vernier cam gear, yella terra billet flywheel, high flow cat 2.5 inch exhaust, t5 and 3.45 gears, it was a lot of fun to an 18 year old me, I put over 180,xxxks on that engine before it let go when the stock valve train decided that 2 years of turning to 7000rpm was enough and it dropped a valve, after it was tuned the rev limiter was set to 7200rpm and it saw it every time it was in 1st gear (18 year old me was hard on the equipment) and sometimes more often than that, I wouldn't mind getting another e-series one day and replicating this combo, although it would be really fun in something lightweight like an xp falcon 2 1 2 2 Searley, bear351c, SPArKy_Dave and 4 others reacted to this Share this post Link to post Share on other sites

deankxf 20,864 Posted January 9 Thread revival on this, I've chatted to Thom, and might make a separate conversion thread section as it's been a big read to get the basic needs for just a later engine swap I'll update this with more once it's fitted within the next few weeks., EA to EL engines are getting rarer in the wreckers, and this AU engine was chosen due to listed low kms (176,000) and AU head gasket is better than a risk on anything older possibly cooked due to head gasket issues. a mate of mine is about to (hopefully) put an AU series 2 engine in an XG current parts gathering and testing has got the engine mounted with the following. (BA alt mounts same as AU2/3 and he had it on a barra engine he was considering using) AU2 engine XG dissy XH air con bracket XH air con compressor(need custom hoses to work on XG?) XH belt tensioner BA alt(because he had it) AU spec water pump and power steering will have XG exhaust manifold and XG intake XG thermostat housing/temp sender Tuff mounts Sway bar for AU/BA some notes @SPArKy_Dave might be able to confirm? will this patch loom allow a BA alternator to be used in an XG with AU 2 engine, or an AU 2/3 car?https://www.efisolutions.com.au/3-pin-alternator-patch-harness?gad_source=1&gclid=EAIaIQobChMIhJL2pKHnigMVVw6DAx0rLzuREAQYASABEgLvzfD_BwE Belt is yet to be confirmed, but it might need to be a custom length, however after looking up the sizes. estimated after measuring this seems a close size 6PK2480 6PK2690 EL V8 shown in pics below way too big. 6pk2380 AU Belt appears way too short when tested 6PK2400 XH belt also too short when tested 6PK2510 AU VCT (likely to be tested soon, will update this shortly) some photos that might help when i redo the conversion thread. Thom's engine back from page 1 XH air con bracket from today's conversion the set up that would work if you were running a BBM (broad band manifold from EF to AU ) log manifold doesn't clear the air con pump this is the XH air con bracket and pump and tensioner with the log manifold from XG basically the above with front view (V8 belt fitted just to check the belt path doesn't cross the intake on throttle body) 1 1 Thom and Tazvan reacted to this Share this post Link to post Share on other sites

(i'll add prices from Jollys price list later when i have time) Belt.. probably similar cost to an EF -AU belt anyway. $40 to $60 XH air con bracket and compressor $ XH tensioner $ AU alternator used.. $50 ish bit of splice with radiator hose to neck it down to the AU water pump outlet size. (probably is an adapter for it to buy) $ intake gasket needed $ 2 Thom and Tazvan reacted to this Share this post Link to post Share on other sites
deankxf 20,864 Posted January 29 continuing on the the AU engine into XG this is an XG radiator with BF Fan mounted (looks to have some trimming done) i'll update/edit any findings. this should be running in the next day or so. Share this post Link to post Share on other sites
