Are you able to provide photos of the kit in this thread 1400r?

From what I've read, the kits are worth a mint, so I'm going to look into fabricating my own.

PM me if you like 1400r. :)

so you can copy it ?

don't think so mate how's that gonna help me sell mine

Or just get yourself a Plazmaman plenum kit, $900 odd. Look a bit better than the Greddy ones and also took me and a mate a couple hours to put on and it was all done, you can retain std TB without an adaptor plate like the Greddy plenum and you can also use the std throttle cable.... except for the intercooler piping does need to bee addressed obviously

That defeats the purpose of looking into an ITB setup.

What do you guys want to know? I've been running the 26 intake and ITB's for a few years on my 25.

I would just like to know what some of the major problems were that you came accross whilst fitting everything up and how u went about overcomming the problem?

Things like what needed to be modified and in what way, such as the VCT which u just removed, or what u needed to relocate?

cheers

I just used a bolt to plug the VCT hole. Needed some gasket material for custom gaskets. I also did a fair bit of port matching. My RB25 is in a R32, so I have VERY little room between the shock tower/brake master cylinder and the surge tank. If the tank ever needs to come off, the BMC is going to have to come out, and maybe the engine. Also, I think I had to use the RB26 oil cooler/filter mount.

      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?
