ok guys i'm putting my running gear "rb30det" into my 180sx & trying to get it to sit as low as i can for clearance issues anyways i was told to use the nissan laurel engine crossmember with rb20 engine mounts & brackets? i've tried fitting the engine to the x member before putting them into the 180 but the sump seems to be hitting/sitting on the x member & the mounts wont go into place by about 2 inches. so am i using the wrong engine crossmember or engine mounts/brackets?

the pictures i've attached is that the correct nissan laurel engine crossmember the seller told me is he correct?

second one is of the sump hitting the crossmember!!

what have people use it the past?

cheers

may sound silly but have you got the xmember around the right way? the lower sump section should sit infront of the xmember, unless its a funky one like the 200ZRs in which case you need a rear humped sump.

looks like the bracket may need to be modified.

with the RB30 it wont be just a bolt in affair.

the motor sits to high.

what i did was purchase a kit off Ebay.com form the US. i used the standard S14 cross member then modified the the kit i got from US - (the kit is to suit a RB26)

you should really be fitting in up in the engine bay and check bonnet clearances because thats where the problem will be.

this is a similar kit but not the same.. its cheap too..

if you still have probelms look on nissansilvia i think they use Cefiro / r33 cross member but not 100%

So with this kit is there still bonnet clearance problems?

we remade the mounts to get the engine as low as possible.

all you need is a case of bear a engine crane and two keen monkeys.

just tac the mounts into place you may need a custom sump or in my case a dry sump.

bonnect clearance is not a problem on mine.

      RB25DET with solid lifters - which cams ?

      By GTSBoy · Posted

      I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.

      RB25DET with solid lifters - which cams ?

      By TurboTapin · Posted

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!?

      "Cheap" bolt on turbo on RB25DET NEO

      By Kapr · Posted

      @Murray_Calavera iam just considering options 🙂 of course it is very expensive so that why i ask here 🙂  @joshuaho96 I looked at that GCG hybrid(i remember looking at it few weeks before) So this is "that" hybrid where i send them my turbo and they upgrade the inside to Garrett stuff and then they send it back. It cost around 1200-1300 USD which is FAR cheaper than the HKS and it is what iam looking for(i just do not have experience like this...to send something off to "upgrade" ) @tylink720 that is like 150 USD turbo no? 😄 I dont think i have the "ease on my mind" with this kind of turbo. I just put over 7000k USD to "LINK" up my engine...dont want to blow it up with cheap turbo 😄     EDIT: https://www.cj-motor.com/gcg-turbo-charger-for-nissan-rb20det-rb25det-high?srsltid=AfmBOooVeOZ6CZ6r1AIv5m-KPaa6BvudIPJTY8LW78khkd-gQlsaCht9 I looked at this and it seems ok? It is that CGC hybrid and it costs around 1250 USD (with back shipping). Do any of you have experience with this hybrid on NEO turbo? I quickly look thru the forum/web and it seems very good.
