sentra Posted May 19, 2008 Share Posted May 19, 2008 18R, 3R, 5R, 6R, 22R, i know nothing about these motors besides im pretty sure they house the size of pistons i want for a rover v8 with a leyland crankshaft according to an acl catalouge based on comp height diameter and pin diameter, (have to machine skirts a bit) and a crude drawing of combustion face, are they common? anybody know of one laying around id like to have a look at the combustion face etc before i go order 2 sets and change my mind Quote Link to comment Share on other sites More sharing options...
UTERUS Posted May 19, 2008 Share Posted May 19, 2008 Pretty common, found in hiluxs, hiaces, some cressidas. Cant give you anymore info, unless it involved your first born belonging to me Quote Link to comment Share on other sites More sharing options...
Spencer Posted May 19, 2008 Share Posted May 19, 2008 depends what series R you want as to how available they are they have different bore diameters Quote Link to comment Share on other sites More sharing options...
Unclejake Posted May 19, 2008 Share Posted May 19, 2008 Also: P76 crank was known as the spaghetti (sp?) crank due to its tendancy to whip like Rene Chignell. Perhaps a good idea - perhaps not. Quote Link to comment Share on other sites More sharing options...
sentra Posted May 20, 2008 Author Share Posted May 20, 2008 i dont actually know what the crank is but it has the same stroke as the leyland, at any rate the motor has been happily(?) run hard for some years just it needs an overbore and its got some odball pistons in it to suit the factory rods (with big half moons machined out of them to clear the crank) so i was looking for something else to replace with, all those r motors according to the cattledog had bores 88 to 92, im aiming for 90 so was hoping the oversize of the smaller ones would put me in about the right place.

Unclejake Posted May 20, 2008 Share Posted May 20, 2008 Have a sniff around RPIV8.com I got some new odd size 4.6 litre RR main bearings from them heaps cheaper than local purchase would allow. They may list a new piston that suits your needs. Quote Link to comment Share on other sites More sharing options...
sentra Posted May 20, 2008 Author Share Posted May 20, 2008 i was wondering why you were so knowledgeable about crusty rv8s, but it just occoured to me i read about you owning a range rover and hating it ill have a look i kinda wrote off those sort of people assuming theyd be expensive cheers youjay Quote Link to comment Share on other sites More sharing options...
Unclejake Posted May 20, 2008 Share Posted May 20, 2008 Mt Lil Brother has a fire breathing P6B. I know more through him really. His has a Discovery block, Edlebrock carb, all manner of speedy bits and it is a delight to drive. I have 'tested' it at the Taupo track once and it was choice.

That's not the orange beast I was watching being very nicely drifted around Taupo on the TV last weekend? Quote Link to comment Share on other sites More sharing options...
