Rb25 And Grex Oil Coolers

[Zardz15]

hey ppl

im dropping an rb25det into my s13. ive searched for answers and asked a few rb25 owners on ns.com but still cant get the right info

so for anyone with an rb25 and a grex/greddy oil cooler and relo kit pls read on and help, im sure its a simple solution but im just unsure

i get how the cooler and relo kit works, its just the part that goes from the engine block to the grex plate that i dont understand how its supposed to attach.

the grex plate doesnt have any bolt holes so it cant go on like that

so, is there some kind of aftermarket adapter plate i can buy? OR do i use the stock plate and stock oil cooler?? i was under the assumption that by running an a/m oil cooler kit that it would eliminate the use of the stock plate and cooler....but maybe im wrong.

so whats the go?? lol

thanks for any help

it screws on like an oil filter would.

Mine came with a centre nut thing that when screwed on holds the plate on. Then you screw on the oil filter to the nut thing. Also ryco Z68 fits onto the Greddy sandwhich plate.

Although mine was just the oil filter kit. No relocation.

so youre saying i still need to use the stock plate though??

yeah ive got the centre nut thing, however it doesnt screw onto the engine block in anyway unless using the stock plate

heres a pic of the bits ive got:

the plate up top is the relo plate, the middle plate is the part that would join to the engine block, and theres the centre nut thing at the bottom.

surely you must have to use the stock plate and somehow block off where the stock oil cooler screws on

you leave the stock heat exchanger and filter mount as it is. the new oil cooler take off plate just goes on in place of the oil filter. so yes, you need to leave the stock heat exchanger/filter mount alone.

question....

ever since i installed blitz oil relocator kit, i noticed the oil pressure goes down after driving awhile. but during morning start pressure raises as usual. its just after driving for several hour i can see the pressure gauges needle just above first line or 1/4 and sometimes warning oil pressure level warning lights up.

what could have cause this?

ok thanks man. however i think its pretty shit that theyve made it this way, surely they could have done something to piss that stock heat exchange plate off? oh well hey.....

My guess is; there's no good reason to take it off, so why not leave it on? If oil temp > coolant temp it will be useful. Might also help getting oil up to temp more quickly, which is important.

yeah fair enough, was just hoping to get rid of as much stuff as possible for a nice stripped back and clean engine. all good cheers

[gotRICE?]

can you even see it under the manifold?

[Zardz15]

under the plenum actually, not manifold. but probly not from the front of car, on the side yes probly, but doesnt matter its cool. i havent got the engine in the car yet but im sure its gonna look good

If you wanna get rid f the whole oil warmer etc etc you need to get your hands on RB20 oil filter mount

straight swap instant delete of whole area you wanna clear up. Swapped mine over when i upgraded from rb20 to rb25 clean and simple.
