i have alot of parts kicking around the shed just wondered which ones to keep and which to get rid on a engine rebuild.
2wd and 4wd inlet manifold
2wd and 4 exhaust manifold
2wd and 4wd head
lots of sensors of both as well
which is best and why
cheers darren

 

to be honest it's all crap, if you like i'll come and take it away for you free of charge

 

If you mean plenum, keep the 4x4 one - slightly better design and flow distribution. Needs the 4x4 fuel rail and pressure regulator - does away with the poxy short bit of fuel line to the reg.

2wd exhaust manifold gives better torque.

I'd keep the 2wd head - gives slightly lower compression when compared to a similar thickness 4x4 head - unless it's an early 2-bolt thermostat housing head/small head bolt washer head, in which case, I'd keep the 4x4 head.
