hi im new

[Anonymous]

i have a 1992 XF ute (the last of the xfs)

it has a 5spd, 2.92 diff, that will be changed to a 3.23 and lots of stickers and a 4.1 carby motor, and performs reasonably

i want to rebuild the motor (no turbo or nothing) and put out around 150 to 160 kw? what products would one use?

in terms of feeding it will a 465 holley(4 barrel ) suffice?, i am thinking ported head, a cam ? what grind , and pistons? i want to have to literally chain the block to the crossmember for when its given the boot

Do you mean 150 kw at the engine or at the wheels??? very different things and very different ways to get each of them... also are you absolutely sure its the carb engine and not the single point injection over head cam engine ...... wait for your reply on this one

Nah, she'll be a XF ohv x-flow, not the Longreach XG with the cammer 4.0, pumbaplus.

The engine can easily do 160 kw with a 465, a good 4-bbl intake, and the right cam, about 280 dergrees or 30/70 with about 215 degrees of open intake at 50 thou lift, a header and your T5 will be okay...just!

Use the XH XR6 3.45:1 diif. It's better than the 3.23, and will allow you to take the big Bird to the limit. If your giving it some curry, a High Energey windage tray and sump is a good move. Don't go over 5500 rpm unless you have lots of dollars.

There's lots of dollars here, but are the emission guys gonna let you take to it with a spanner?

ED/EF/EL/AU/BA wagon, XG/XH rear ends. I believe the bit where you bolt the taily onto the EB onwards diff is different - is it easy to change the bit you bolt the tailshaft onto to take the Borg-Warner / C4 / Toploader style shafts? Whats the standard 4.0i + BTR le85 rear ratio, 3.23:1?

Otherwise that sounds like a very good mod for a later model leaf sprung Ford..

Easy if you can crawl under there with a suitable made-up tool and crack the 100 ft-pound nut on the pinion shaft, then pull the flange with a puller.

Not impossible, but not so easy...

yesah shes the wheezy old 250Xflow, and i want around 150 at the fly wheel.
is that holley a reasonable carb to sit on it?

the standard drive train for the manual was the 5 spd and a 3.23 or a 2.92 or a 4spd and the 2.92 or a 3.23.

what would you estimate it would cost to build it up ? i will get all of the machining work done by pros but as i am reasonable with a spanner will build it up myself.


cheers boys

is there any way to strengthen the T5? or would a T5 from a EL or the lik e do it?

 

[addo]

Either pick up a Celica steel case (prob the best bet) or get an imported Mustang T5. Bugger the people who get precious about the Falcon ones here.

why should u need to strengthen a T5? they bolted them into xr6+8's and hsv's in australia and some real big stuff overseas.

Because the Aussie built the trannies in Austrailia in non-world class cases, with non-world class gears. The V8's got the gun gearsets form Mustang CobraR's and this was heaps better than the standrd six cylinder Falcon stuff. Mainshafts were different, and there was a lot of changes to cope with the added 283 to 310 lb-ft the V8's got. XR6's only saw 270 lb-ft, and often less than 260 in the base cars. The six ran wide ratio gear sets, the close ratio ones on the eights were very strong up to a good 5 liter or a mild 5.8. Over that, it could get toasted easily.

Why do you think Falcon T3's with 5.6 Windsors ran Tremec's? Beacuse the T5 blows apart over 330 lb-ft, right where the current BA Falcon XR6 Turbo taxes it's T5.

If you use a six cylinder T5, don't do any mods which put the torque over 280 lb-ft, or it'll cry foul!

fair enough. that makes good sense to me. are the internals for the 8 cylinder compatible with the 6 cylinder box?

 

[xctasy]

Yes, but you have a bit of an issue with the mainshaft. The six and V8 one isn't the same, for some reason. One of the factory XR6 Group N rally cars had a set of six specials made up by Ford Austraila with V8 gear sets on a six cylinder shaft. The lads at Broadmedows told the guy not to break them!

If the boxes were the same, I'd just be swapping boxes, not internals!

I think the Commodore V6 5-speed had the same ratios as the 5.0 V8, whilr the Holden V8 had a similar ratio spread to the Flacon XR6, witha taller first. Someone like Mel Wood could tell you what the best options are. I'm an Automan...to drive a car like a forklift is my aim in life!

It comes back to my comment about the Tojo boxes... These are tough, cheap enough, and serviceable. Bellhousings are available. As to the T5 - I've not yet forgiven BW for the Model 35, LOL. You'll spend more making it equal to the steel case.

 

[Anonymous]

mmmmmmm tremec

i dont reckon any one has forgiven them for the BW 35!!!

 

[Anonymous]

Just curious; What does it take to bolt up a celica 5 speed to a 4.1L and does it fit into an Xf?

 

[addo]

You need the bellhousing, the box, the adaptor yoke and uni, the pilot bushing and clutch disc. Maybe a trans crossmember, too. Also look for a suitable dust boot. If you want one, I know of a box down here for $500-ish with the correct yoke and (I think) the clutch disc.

Cheers, Adam.

i think i have killed my box !!!! damn it, was doing some circular manuevarsat a recent BnS and noticed the next day the bearings sounded a bit dicey, i have got some quotes and im looking at around 500 just for a bearing kit, i want to stick with the 5spd cos there briliant on fuel on highway, any suggestions if im going to keep doing such things and towing heavy loads?

Talk to gm destroya. He's into Toyo-boxes. Normally aspirated Supra and, especially, the Supra Turbo 5-speeds are bullet proof. Commodore Challange stuff again. Bomb proof.

Steel case Toyota Hilux/Hiace/Tarago(?) boxes, and the early pre 78 to 86 RWD Celica/Supra boxes are cheaper but the Hilux has bad ratios. Not as strong, but you can get 'em cheap. Stay away from alloy case Toyo boxes, and also the T5 unless you are rich. The yards think because its a crappy low-rent Non-World Class Aussie BTR made 5-speed it should be worth the price on a World Class BW T5. Aint so.

I'd be looking at a CrapyDore THM 700 V8-spec auto box with a huge overdrive. Rebuild it, and then you can then drive it like a forklift :splat: :fume: :wrench: :smash: :shockin:

As for me, I miss the good old Toploader. A post 1976 US import will have an over driven fourth on it. Only problem is the main shaft isn't serviced any longer.

Ford needs to drop the local T5, and give us a proper V8-spec box on all sixes.
