The r33 turbo is a cheap replacement. If you have cash, a gt2871 is nice also.

Installing R32 crossmember on s13,
what to do about power steering lines?

simple bend into place by hand suffice?

Found it lol, picked up the kit off summit aswell.

Ill probably have to do a little more custom work, most likely utilizing AN fittings.

Good lookin' out

smoked240 · 12-09-2010, 11:31 AM

is there any other turbo elbow i can get that will bolt onto my rb25 stock turbo and bolt onto an sr20 down pipe and clear my steering on my s13 besides the skyo?

Not to my knowledge. I had to fab my own out of my SR downpipe and a Ebay R33 RB25 elbow (I think it cost $45), and I took the opportunity to add flex sections on both the 2.5" main outlet and the 1.5" wastegate outlet, then merged them under the steering shaft.

smoked240 · 12-20-2010, 10:36 PM

I am trying to get my MAF sensor wired into my Series 2 rb25 and am having troubles. Anyone know which wires an E60 maf would go to? thanks.

I bent mine by hand around r33 cross member, be very carefull not to kink it, or you can fix the kinks, it actually wasnt that hard to bend it around the crossmember.

I need a neo rb25 and have a chance at an automatic motor set. I already have a 5 speed tranny so just wondering if the block rods pistons and everything else is still the same thanks

Why would you think the Internals and everything would differ between auto and 5 Speed.

Engines are exactly the same.......

240sxrb25 · 01-01-2011, 08:11 PM

Hey just asking a legit question before making an expensive decision dudette

Thanks haha

Also did all the noes have the crank collar fixed?

240sxrb25 · 01-08-2011, 06:34 PM

What that popcan shaped thing. The neo awd automatic motors dont have it.

It isnt fly by wire is it?

Sileighty_85 · 01-08-2011, 07:30 PM

Bigger pic would be better, But it looks like traction control

towlie · 01-09-2011, 03:12 PM

Just popped my rb20 into s13, (r32 crossmember). Stock ka transmission support does not seem to fit/line up, what are some alternatives I could try?

It's traction control, it's a second thorttle plate in the throttle body. Some Neo's have them some do not.

They did not. 3 of the last 4 Neos that came through the shop did not have a collar fix from factory.

From what I've concluded Nissan used the remaining R33 cranks that were overstocked (since they are identical in specs) during the beginning production of the R34 neo motors. The R33 cranks that weren't fixed were used and thus a NEO without a collar fix. It's a shot in the dark with them. GL

I am wondering the best way to remove the flywheel from the rb25? I am currently at a standstill, i cant figure out the best way to keep it from spinning??

^^Coolwhip, i sent an email to raw brokerage about ordering a set of intake and exhaust valves, but i realize they are not listed on the website. I was going to order from FRsport but they only sell them individually. Id appreciate it if you can point me in the right direction.

Are Supertech and Ferrea the only aftermarket valves?

Sileighty_85 · 01-11-2011, 11:19 AM

Get friend
get appropriate sized socket for front crank bolt and breaker bar
put socket on front crank bolt
have friend hold breaker bar
break bolts loose

jbballa9876 · 01-11-2011, 11:47 AM

Alright thanks yea i thought that would be the way ill just need to put my crank pulley back on and do work.

I got one on my s2 rb25 and bought a neo recently to replace the s2. I have never ever heard of it not working.

240sxrb25 · 02-14-2011, 02:07 PM

so i tore my neo rb25 (awd motor) apart today

i noticed the beefy oil pan is secured with 14mm's rather than 10mm's because of the front differential.

my question is can i used a spare standard rb25 oil pan ad just drill the 10mm holes larger for the larger neo bolts?

or do i just need to cut the diff housing off and weld it up? if i go this route will the neo pan clear my sway bar with rb25 crossmember?

shaul_240sx · 02-17-2011, 08:38 AM
