Sump Issues

[Morgz32]

ey fellas

got a bit of an issue here i had an RB25DET in my r32 gtst-4 and now im putting the RB into a 180sx i took the 4wd sump off and bought a standard RB25 sump from jap parts plus.. When i wen to put it on this arvo nothing lined up the sump seemed to short which leads me to believe they have given me the wrong one

just wondering if anyone has any other possible ideas to why the so called standard sump doesnt line up with motor??

cheers

4wd block is wider then 2wd , need to custom sump with cast ally one .. cut diff off n weld her up

[Morgz32]

i didnt think that RB25's came out with 4wd...shit ay

[ahh 33 s2]

^^^^ what he said.. a 2wd sump wont match a 4wd block. i bought a modified rb26 sump put in my GTS with rwd 26 in it

[Morgz32]

what would be the best suggestion im going on atm buying a rwd 25 bottom end and smashing the head off mine on it... or just buying a cheap 25 unless thesre is someone or some shop that possibly sells custom sumps...

If you're going that far might aswell get a 30 bottom end and smash your 25 head onto that..

You can always remove the front diff and mod your awd sump @ embleton or some other ally welder

if you want to go as far as swapping blocks then RB30 would be cheaper, more torque and theres a few rb30 modded sumps on the market

so ur saying its a stagea rb25 engine? just bout month ago put an rb25 into a 180

25/30 in a 180sx.. sounds like fun times!

Pretty sure that's your answer to everything....

Lyell can you replace that light globe in the lounge room? "Yeah, I'll smash an RB30 up there"

LOL Nathan.. at least in this instance it's actually cheaper and better if he's considering swapping to a rwd block!

P.S. I was waiting for this

problem solved guys, was thinking of the 25/30 conversion but in the process of a hopeful/ succesful 26/30 build for my 32..

as i was removing the silicon from the bottom of the block i started digging up little 10mm thread holes in the block, once i cleaned the bottom of the block and changed the pick-up ad dropped the 25 sump on it all lined up, the guys who did the conversion on the car before i bought it muct of tapped out new holes for the 4wd sump and diff... all the stressing and all i had to do was clean it abit

thanks for the advice fellas have a good chrissy!

Sweet as! 25/30 in a 180 would have been fun though

Second set holes are on all 4wd blocks . If your using tin sump how did you modify mount brackets for bottom row of bolts to hold box against block ??

Are you talking about the wings that bolt to the bottom of the bellhousing?

Bottom row of bolts that go into cast ally sump , not there when you use tin sump

[bubba]

Not sure what he's done with the gearbox but a rwd box has the wings that bolt to the side of the block..

4wd block dont have bolt holes in side like 2wd block for the brackets to bolt too ..
