Hey guys i have been wondering for awhile about what the difference between the RB20DET head is on the NA version and also FI version!

i knw the cams on NA is slightly bigger but wat about the rest? and is the NA head compatible with FI block? i beleive it should be as they are both RB20's but would just like to confirm.

thanks

no one knows what the f**k you are on about and it apears to not really be worth asking

I wouldnt say that dude.

Using FI (forced induction) as a replacement for turbo is a bad idea for starters though in terms of the community.

Either way, I cant answer the question hah

I would assume the same, bar the cams - someone else would need to confirm

hey mate, no difference in the heads... cams different, but thats all... springs etc, all the same...

as for using a FI bottom end with a NA head, it really depends, if you are changing to NA pistons to up the compression ratio, then there is really no difference to using the NA block (though the FI bottom does have squirters, please correct me if the NA bottom end does not), and there would also be the issues of blocking the water and oil lines, if going NA...

really, it would be alot easier to use the bottom end that suits the application...

cheers mate, hope this helps...

"no one knows what the f**k you are on about and it apears to not really be worth asking"

as for this absolutely useless statement, your no better, than what your accusing the bloke of... really useless

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
