I'm not getting any love over in the Forced section, and this is fairly urgent, so here she goes-

Looking at replacing the blown series 1 RB25DET in my Cefiro with a series 2... Can I use ALL of the existing series 1 loom including the ignitor pack and my Splitfire coils? Coilpacks will bolt in with no drama?

Thanks

:huh:

lol I was suspicious it wouldn't be quite that easy... so the plugs are easy enough for someone with very limited electrical expetise?

Have you done this swap Toffy?

I have a series 2 engine in my S1, the ony remaining series 1 part is the coil packs, because the igniter on S1 is mounted on the coil cover on S1, and S2 have a different ECU which ignites the coils. If you can avoid it do NOT use the S2 turbo, I am advised they can not stand BOOST, they have a PLASTIC/SINTHETIC blade/impellor, I am advised not much good. If you are changing you ECU you can use the S2 coils, so long as the new computer is S2 compatable.

dont talk shit about the s2 turbo, its as good as any other rb25 turbo(if not better than all but the r34 type), and yes its simple to make the plugs im talking about fit, if your keep your s1 motor close and whatever doesnt fit switch onto the s2, easy as :) .

Blown engine isn't going anywhere for the time being. The hardest thing I've done auto-electrical wise is hardwire r32 type coilpacks into a C33 loom so hopefully I'll be ok with the plugs. Standard turbo will be making way for the T04e kit that already resides in the bay..

Exactly. The exhaust wheel will let go long before the compressor wheel packs it in.

      Mistakes were made, my R34 Story

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      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.
