S14 With Neo Rb25 Drift Car.

[R31 POWER]

Bummer man I always like reading the new posts in this thread but not this time! Whats the plan now?

[Simon-S14]

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.

[Simon-S14]

turns out the neo does not have the long nose crank :S so still got the shitty short drive with all of 4mm of engagement on the oil pump.

will certainly look at doing all those thats for sure.

Will you need #2 rod resized/matched?

I've still got these pistons if you want them.

[Simon-S14]

sre they 86.5's? come with rings and pins?

if so how much again?

[bigkevracer]

That looks suspiciously like Andrews shed. If you keep him busy my exhaust will NEVER get done!

[Simon-S14]

haha it is.

Click the link in my signature.... comes with everything, new in the box for $1250 yes they are 86.5mm.

Got a crank aswell but doesn't look like you need it.

[Simon-S14]

funny you should say that... just got a call saying my crank is cracked... off to a good start!

[Simon-S14]

and now i have another crank... out of a 33 motor. while i was at it i took a stack of pics of neo vrs R33 pistons and rods... the differences are huge,. uploading now

[Simon-S14]

the clean piston is the neo one.

[Rolls]

What are the main differences?

[Simon-S14]

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.

Good to see a direct comparison and the photos are great, i am hoping i don't have to see the insides of my engine for quite a while yet

[jamie curran]

hey bro, well done on getting a crack, and those photo's are priceless man.

[NYTSKY]

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.

[RRob]

Yer just noticed the 05U stamp on neo rods.

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
