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.

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
