I got lucky today and found a 125a alternator that looks like a Hitachi and a noticeably wider in the outer metal section between the ally casings . I found it by mistake in a wrecker 92 Maxima with an early VG30 in it . Usually the 110a ones turn up on 97 98 A32 Maximas with VQ30s in them .

The mounting ears are the same with the front tensioner one on centre so to speak . RB alternators being on the drivers side have the top ear slightly towards the engine so need to mod the top bracket to suit the Maxima alts . Maxima VQs don't tension the drive belt by moving the alternatorand and depending on the year and VG/VQ engine can be above or below the AC compressor . I scored a slotted tensioner bracket from an early bottom mount car and another from some top mount Nissan , transverse KA I think . I also got the threaded adjuster block and bolts off some Nissan that tensions by hinging the alternator RB style .

These later alternators have a different connection to the early large spade type . I only have one good plug and I'll have to see what my car has standard .

$45 for a second hand 125a alt sounds good to me , cheers A .

Yeah I have a string of alternators off various Jap things now starting with an LR165 off a Vortex and the Z32 LR180 that replaced it .

I scored a genuine Hitachi LR1110 (110a) which had been freshened up for the R33 , then stumbled on the 125a one which I pretty sure is a rebuilt Hitachi LR11125 in Maxima casings .

You see the odd copy of Hitachi alts and you can tell by there being no Hitachi stickers and the plating on the nuts and bolts is silver not that gold appearance .

Anyway we split the cases off the 125 and washed it all up yesterday arvo . All looks pretty good though the back bearing is a bit tired .

I honestly think 110a is plenty to have in a car that has 80 standard particularly a 90s Skyline without all the luxo elec pork .

One of my failings is I can't resist rare upspec bits particularly when the bite is virtually trivial .

Must stop collect alternators , cheers A .

Yeah well it works out to around $155 cleaned tested and with new NTC (OE) bearings if the reg rectifier and brushes are good . That's with the help of a mate and the workshop with $50 their way because I don't use people .

The RH9 one has the better front case tensioner mount position but even having to make or mod the bracket it's heaps cheaper and any Maximer alt with the right pulley and socket goes bolt plug . $155 vs 6-900 , the plain lookin one wins .

I'm reluctant to think there is anything special in the RH9 one and if there is it could be higher speed bearings - and lairy paint .

Of course a bright blue pully and stator is worth at least a second in the quarter ... 100% !

Any one heard that the I30 160amp are straight bolt-on affair ? a chap in UK said it was straight bolt on on his r32.

I'm trying to buy one from mechman or DC power in the state.. but none are willing to take a R32 case and rebuilt it or make a custom one.. obviously they must think the market is not there and they wont sell enough for them to make it worth it.

      "CAD" version 1.0 It will have a 15mm lip around the top for 6 × 5 or 6mm nutserts and fixtures (two on each of the three straight edges), and some pinch weld on any exposed edges, it has three mounting points, one of the power steering reservoir bolts, and two on the rad support, my 120mm hole saw will make short work of hole for the silicone joiner, with ample room for some pinch weld  I've also got enough Carbuilders "peel and stick" heat shield to cover the outside of it at the coolant expansion tank and on the engine side, as pictured, and internally on the lid and where the fuse box is, I've also got some thin, about 3mm, black 3M single sided sticky foam stuff that was left over after sealing some door drafts at home to help seal the lid As for the shape, it "sort of" matches the shape of the fuse box, so shouldn't look to "out of place" The lower area and hole for the intake will need pinch weld with a balloon on it to fully seal the hole and bottom of it, that will happen after it has been fabricated so I know exactly what size is required  Filter service has been trialed,  and so far it was a simple process  Just need to get some alloy, and then head into work to use the guillotine and break press in the workshop Hopefully it should be sorted in a week or two Guestimated outlay will be under a $50 for the stuff I don't have on hand (alloy, 6mm nutserts, the pinch weld, and wrinkle paint) Disclaimer: That's what the "voices in my head" are telling me how the filter box should end up getting done......lets see if they know what they are talking about

      Have been polishing up the trailer rims as they had been sitting in the shed for a few years and are really in need of some love. This was after a couple of passes with chrome polish - coming up quite well ✅ .

      Welcome aboard! Is your Skyline auto or manual? I'm assuming manual. Does it have any mods done yet?

      Another "where do these lines and plugs go" RB25DET question

      By Yeetus · Posted

      Hey mate, the brown and grey plugs would usually go to the TPS, brown one goes on the bottom connector and grey is the top but isn't used unless the car is auto, your TPS looks different to mine though I've got a series 2 engine.
