Hi guys

have done some serious work to my engine atm:

2.9L stoker kit

Neo ultimate head

Tomei 260 camshafts 

Yellow jacket coil pack

otaku garage forward facing intake plenuim with a 90mm throttle body

and I’m not even on my L plates yet

thats why I’m doing all this work so when I get my p’s I can do an actual gtt turbo not a plus t setup

so if anyone has suggestions on what I’m doing and what I could do better please let me know 

but back to my main question 

can you convert the internals of a gt gearbox to a gtt

ive heard there the same just internally different but want to be sure

and should I be upgrading diff and drive shaft

thanks jack

No. The NA gearbox is physically much smaller. Like half the size.

You don't need to upgrade either the diff or driveshafts. Not for strength reasons anyway, as the diff is the same strength as the turbo item and the axles are nearly as good. But.....you will want an LSD centre on a turbo.

Note that I said driveshafts. You said driveshaft, and it is not clear whether you meant the tailshaft or the axles. Not that it matters, as both are strong enough.

It's also not clear what the stroker kit and other parts are fitted to. The NA engine? A turbo engine in the shed? If you've done it to the NA, complete waste of time. If you've done it to the turbo, well, the yellowjackets are not a good choice, but beyond that, everything else is OK, if largely a waste of money.

You will need brakes. And, are you sure that you will be allowed to drive a turbo on your P's?

Hi mate 

yeah meant driveshafts sorry typo

and the n/a block is exactly the same as the turbo 

And do you know what ignition coils I should run

im using the n/a block as it’s the same as a det but am putting det head on top

perfect example of why not to fit that style of plenum. lost 1000rpm of response and a bucket load of power. Green is factory plenum, the others are a short runner style plenum. Bin the yellow jacket coils and get a PRP r35 coil kit.

Ok thanks

just wish the stock didn’t go over the valve covers

looks ugly and is really inconvenient when working on your engine 

and do r35 coils stick out of cover?

It's really not hard at all to remove the crossover pipe as required, which is not often.

Get split fires if you want it to all fit factory. You will have trouble with yellow jackets

But look at the peak gain! And how much cleaner the engine bay looks.

I don't like the look of most of those plenums and fitting the new plazmaman ones with engine in is a pain with the water hose/pipe underneath.

No its NOT mate, no piston oilers for a start, and past experience of these blocks found that the turbo oil supply gallery has not been drilled either, or the turbo oil drain hole as well.

Ok lol

lucky i haven’t installed anything yet

does anyone know if you can run the det neo engine without the turbo using parts of a device engine?

And just so everyone knows I’m not dumb it’s just I made a sau acct less than a day ago so am still learning 

and robbo I thought you meant put r35 coils in a rb 

that’s why I got confused

    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
    • So, a bit of a side trip, but one that might be interesting for people with JDM cars and japanese head units. I know @Pac previously posted about a carplay/android auto adapter he installed which used the AUX input, and @V35_Paul put in one of the Tesla style units that replace both screens. The option I went with was a Lsait LLT-YF-VER5.87_2 (https://www.alibaba.com/product-detail/Lsailt-8GB-Android-Multimedia-Interface-for_1601187633672.html). Price was $1,150 for a single unit although they are much cheaper if you are willing to buy 2....$857ea. Make you you get the version 2 not version 1, it is faster and has a better UI - this is the manufacturer listing: http://www.lsailt.com/product/348.html. BTW if you've never bought from Alibaba before, don't be concerned....these guys can't stay in business unless they are responsive, ship fast etc, they were excellent (probably faster shipping than most local places) So, this was my task for a lazy Sat afternoon....looks complex but was all done in a few hours (it probably helps that I had some of it apart before so it was a bit familiar). I also decided to add a HD USB drive recorded at the same time and the unit also supports an aftermarket reverse cam (if you don't want to retain factory) and also AV in and HDMI out It looks much worse than it is, in fact in was genuinely all plug and play (no custom wiring at all). This video was pretty good (skipped a few steps), unfortunately they are an Aussie seller but no longer sell this unit (I guess Carplay/AA adapters are easier to install and much cheaper) https://www.youtube.com/watch?v=T5hJfYOB8Dg
    • That still isn't a lot to go on. I don't have a Y50 Fuga Head Unit wiring diagram. I can say that a lot of nissans of that age shared head unit plugs, so if you are in Australia something like this would probably help: https://aerpro.com/app091# You plug that into the car loom, then either plug the head unit ISO into that (if it has ISO), or you buy and ISO adapter harness that you wire in. Bit of stuffing around, but once you have ISO its easy to change things in future.
    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.
