what things need to be changed and how much hassle is it to put a 4wd engine into a 2wd cossie??

i bought another engine to go in my 2wd out of a 4wd as the big end went on my car... matey who fixed it put the 4wd bottom part into my car and put my old 2wd head on top... but is it simple to put a 4wd on there? the cylinder head cracked after about 1500 miles so am lookin for another head (as per sheps thread in wanted!) but they seem to be getting scarce lol

 

straight swap as far as i know, you'll need to plug the oil feed for the turbo though and use the 2wd setup from the inlet side of the block,

 

Ah so why was this matey who is fixing his car on about having to change temperature senders and all sorts of gubbons??

 

if you're replacing a 2wd head with a 4x4 head then :

the temp senders for the temp gauge are in different positions (2wd front drivers side, 4x4 rear pasenger side)

the 4x4 head doesn't have the mounts for the turbo damper - if you're using a 2wd exhaust manifold, you'll need to use something like the Bailey turbo damper

you'll need to use the 2wd thermostat housing, unless you fit a 4x4 water pump

you'll need to blank off the turbo oil feed if using the 2wd feed pipe, or screw the oil pressure sender straight into the block if using the 4x4 oil feed pipe

 

2wd heads on 4x4 blocks = lower comp, i'd put the 4x4 head on as its a better design

And take note of what jon's post says

 

true - and probably not a bad idea considering the amount that has been skimmed off most heads by now
