Ok so after so shits and giggles I have been looking at turbos to replace the ones on my cars

For the R32 I'm looking at twin Kinugawa Billet TD04H-19Ts, should give same response with more top end

Chance of working 95%

For the R34 I'm looking at either Kinugawa Billet TD06L2S-20Gs or Garret GTX3071rs with the front housing off my HKS GT-RSs and some Kando T25 GT30 rear housings, should give good response and quench the RB30s thrust for air :D

Chance of working 80%

This thread is about odd twin turbo setups, if you have some post em and why and an estimated chance of working like you want them to

I'm looking at doing a set of -7s with billet kinugawa 60mm comp wheels (basically -5 size) on a 2.6 for a bit of an experiment

Chance of working at a guess 75% provided it doesn't go straight to surge due to the smaller front housings

I'm monitoring this thread. Curious what GTX3071's could do in twin form. Also what kind of manifold would you need for twins that size?? I've never pulled a gtr apart so I don't really know how much room there is

over 500kws and a cracked block ;)

That is an interesting idea, that Hawkins dude put -7 comp housings on to -5s and got decent results with it and with the Billet wheel should be even better :)

That's more an idea then something that will actually happen, but if it was possible/managed to do it would easy pass 500kw, I have got 458kw with the GT2871Rs ( HKS GT-RSs ) and got boost limited due to the rear wheels choking it at over 28psi

My idea is Kando T25-GT30 rear housing to bolt in to the factory location on the standard manifolds and use the GT-RSs front housings to keep the engine bay as stock looking as possible :D

mick i have a hks 3037s twin kit your r34 would like

I actually looked that up, the 3037s are GT3076Rs and are to much comp wheel for what I'm after and also very unlikely to fit the factory location :(

over 500kws and a cracked block ;)

500kws at the wheels is the idea, but why would that crack my block, can the RB30s not take that much power

that was what I thought he did, makes me feel even more confident now

I have seen a few cracked blocks lately on cars running e85, seems the cylinder pressure just splits the bore from bottom to top. It's totally up to your tuner, and how much timing he decides to run, I hope he is good because you can't see massive cylinder pressure, and you can't know when it is too much for your block to handle.

My suggestion is to keep the bore thick, not oversize the pistons. Or perhaps sleeve the block...any strength there will help.

What about the FP HTA 68 mm comp wheels, Micky?

I did think about them cause they are a good piece of gear but with what exhaust side, Owen Developments do one boltin for the RB26 but it is still the same rear wheel as I have now which isn't big enough :(

Would be good in your -5s though :)

Brett's idea is would be even better for you though me thinks and the idea of this thread, bitsa turbos in twin form, engine doesnt really matter just throw together turbos you have done or have thought about doing :thumbsup:

Hmm.

Would 0.84 housings fit in a stock position? It would mean custom dumps but.

Those 68's are too big for me. If I did anything, prob the 60 mm gtx's in stock housings.

Lithiums idea was a rip snorter. The trust t517's with their bigger rear wheel and the FP 68 mm front fans. I think that's what it was.

Kando have a billet Kinugawa TD05H-18G that would be close enough to Liths idea, same exhaust wheel and housing and a Billet 68mm comp wheel, just not the HTA gear, which I would consider one step up from where I am now

3071's seem to work fairly well for a 3L engine, this is another members car on aus300zx. Not an RB but still 3L :P

98 RON 446rwkw 23PSI

98 RON+ Water Injection 489rwkw 23PSI3runcomp001.jpg

That doesn't look all that laggy given twin GT30 rears on a 3.0, give me hope of a good result if I go that way :thumbsup:

not they wouldn't fit cause they don't make a compact .84 housing

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • 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:) Comparison of the 2: 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.
