what i meant by my mates motor is non turbo is.. its a factory non turbo motor, with a turbo setup on it. im terribly sorry for wording that very wrong!

i was trying to get the point across at the strength of an internally standard rb30

ahh so you meant to say, non turbo bottom end?

having a non turbo bottom end really makes little difference to the equation but now we have that cleared up, we can continue, fully enlightened

yes i meant its a non turbo bottom end, and head. wich doesnt really matter anyway cause the only difference is the cam which has been replaced anyway, but thats the extent of the headwork done to it.

i worded it badly :/

The pistons (comp ratio) is different also.

What Nismoid {edited for accuracy} said before was correct, though, you won't be able to make the chassis backwards compatible. You can put engines of equal vintage in but I'm pretty sure putting a less efficient engine into a newer car breaks all their rules

look im sick of arguing with everyone in here, i hope ive corrected all my mistakes by saying everything ive previously talked about has been turbo. big power n/a rb's just doesnt happen.

now, if we want to talk about my car. the idea of putting an rb30 in came to me because as ive said i can get one for basically nothing and i can do all the work myself. being an apprentice i dont earn lots of money so i want to do it on the cheap, and n/a rb25 is hard to find in its self, and expensive when you do find one. im not looking for performance out of this car at ALL while it is n/a, i just want a nice cruiser. due to previously having a turbo car and being on my p's i have a daily driver so i have plenty of time to do all this. SO in summary, an rb30 is the cheapest and quickest way to make my skyline n/a, then when i want to step it up all ive gotta do is chuck a twin cam head on and away i go

if anyone else wants anything cleared up feel free to ask!

yeah the head gasket in it is thicker thus making it the same as a factory turbo rb30

If you want to do it and your budget allows, then ring DOT/RTA and see if they will allow it. As far as being ABLE to be done....sure it can. Go for it.

You can always rip the head off and go twin cam later if the peer pressure gets too much.

Go and read my post.

Then read it again.

Then continue reading

The car is BUILD PLATED as TURBO.

- You cannot put a RB30E into a R32 and be legal if my recollection of laws is correct (I'm usually pretty on the money), meaning RB20E and RB25DE are your choices etc. You cannot put an older motor, into a newer chassis.

- You need to RE-ENGINEER it, that is not free to begin with. They might also emissions test you, again not free.

It's not a simple case of "motor out, motor in - I've beaten the system".

It might pay you to investigate the laws before getting wild ideas.

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      What about if you just give it direct 12v and earth?
