S14 With Neo Rb25 Drift Car.


Recommended Posts

i phone doesnt do close ups lol.

crank is ok ish... number 2 is the only bearing thats damaged.. number one shows significant wear also. measured it up and number 2 on the crank is only ever so slightly under the minimum tolerance. soooo.. gonna get it reground 10tho undersize and go with the larger acl Race bearings, new mains, new oil pump and then re assy.

pistons, rods, rings, bores all look like they just rolled out of nissan. not sure if i should bother with going forgies. no det marks, no nothing on the pistons.

If you can pull it all out yourself then I would save the $1k for forgies, almost all dead motors are oil problems. Go baffled sump, oil pump, bearings, crank collar (or is this fixed with neo motors?)

If you kill it via pistons then it is almost certainly det related which means tuning and you said this is sweet.

rods are fatter.

with the piston the crown is hollowed out with two large holes allowing oil to be squired up into them, the rods have a tiny oil hole facing the crown, along with the piston bore squirter. the ring lands are fatter on the neo's and as for weight the neo piston and rod even tho it has more material is slightly lighter then non neo.

RB26 and NEO RB25DET rods are the same.

Definitely throw some forged pistons in there while you have the motor apart, get the rods resized, everything balanced and away you go.

Since you've done so much damage, why don't you just get another neo from a wrecker and go again. It only died because your oil was on the track. I think a neo with a good sump will last for ages. 90% of rb's die from oil starvation of some description, or a bad tune. Don't see too many die from being pushed too far
