4.4L how far can you take it

[mick&shon]

i have a 4.4 p76 motor due for rebuild what mods and how much can i get out of it........ performance wise??????

[lucy]

How much do you want to spend?

[mick&shon]

im not spending big $$$$ but i want it strong and reliable how far can you bore it and what pistons can be used

[mick&shon]

whats the deal with head gaskets how much machining with heads

[grungle99]

Mine is out to about 5L - although tired and needing rebuild now...

Landcruiser liners, Holden pistons, 3.5L heads and spacers, Crow high torque cam, Scorcher (Bosch) electronic ignition...

Ran the oil engine oil through a temperature based bipass so when the oil was up to temp it ran through a cooler. The unit was in a County and ran real well for a long time.... just plain worn out now... needs some love...

There is heaps you can do, but to be honest, a "not far from standard" 4.4 is a better option then all the money in doing the build to get something that another badge can offer in standard form... (and yes I am a rover purist but see the reality of things too...)

My 2c I spose

would a 253 be an option the reason i say this i have a 253 in the shed i have engine mounts to do the conversion a cluey mate of mine recons he could modify my bellhousing that i have to put a holden into cruiser to suit disco 5spd

i know its only a 4.2L but they werent a bad donk in there day

Maybe cheap to swap but you will need a engineers cert and not really worth the effort i reckon.

Not a good way to see a rangie hope ya missus and any one else in the rangie are ok .

Id stick with doin up the 4.4 over using the 3.9 not saying the 3.9 is a bad thing its just the tourqe from the 4.4 with a good cam is lots better keep the layland heads on it too they have better ports and bigger valves than the rover heads .

As for the 253 thats a step backwards the 4.4 will deliver more power and tourqe if you are compairing standard trim motors and like loanrangie said will require eng cert

[rustysrangierecks]

the only good thing about a 253 is that you trip over them they are that common and cheap.. and you can cook them to get home if you dont have a tow home or spare radiator hoses..

[mick&shon]

thanks lokka ,yes the missus was very lucky, how much do you know about auto's in the early rangie (80mod) i picked up a 2 door the other day cheap with crook transfer i pulled the back of the transfer out last night to find the differential unit completely chewed up including the end of the rear out put shaft can you tell me who would have one 4sale.

[rustysrangierecks]

i have a 4spd center diff and rear out put shaft. if you want it i pm me

[mick&shon]

mine is auto does that make a difference to internals?

[rustysrangierecks]

depends what auto you have. if you have the conversion that is where the auto is hooked up to the 4spd rangie box via adaptor plate(they just take the 4spd transfercase gears) or where the auto gear box is in the 4spd casing or the zf auto.. i stand to be corrected

[mick&shon]

well does this help......... in this gregory's workshop book the 4spd transfer looks the same as what i have, but ill grab a torch and go and have a look

[mick&shon]

righto its has adpater and the bellhousing has "RITTER ADPATER" on it, the auto looks like a C4

[Loanrangie]

Ritters mostly used C9's i believe but it may be a C4 - at least its not a BW35 that was commonly used.
