If you're on a budget just go a Kando T67 or TD06, Yellow Jackets will be fine, run series 2 yellowjackets because they have built in ignitor's. Injectors 1000cc Injector Dynamics, cheapest ive found so far are from Lewis Engines. Plenums...depending on budget, ebay FFP, greddy FFP, plazmaman plenum to keep you're long runners. Throttle body 80mm is MAX you'll need. Exhaust manifold, porting will cost almost as much as a 6boost.

EDIT:

injectors flowing more than 500cc/min are usally low impedance injectors because of the faster response times of the peak and hold pattern

and it depends what fuel rail you run, most common is 11mm and you cant beat ID injectors.

Depends how set you are on 300+kw at the wheels.

You can get near enough with stock manifolds (inlet and exhaust). A GT3076 will bolt to the stock manifold with a spacer.If you do want a front facing intake your stock throttle body will be fine for 300kw++

What kind of Stagea ecu do you have? If it has two rows of pins it can't be Nistuned. If it has three rows (like an R34) it can. But I would save the money not spent on manifiolds (at this stage anyway) and buy a Link/Vipec - then you won't need any kind of afm and will not need to update your ecu again.

I have a mines chipped stagea ecu & a r33 s2 ecu that can be nistuned. So you reckon link/vipec are better than the haltec sprint 500?

I'm not really keen on buying another ecu seeing as I have the r32 one, a mines stagea one, an r33 one & the haltec haha.

As for manifolds I'm going eBay forward facing ($200) with billet fuel rail & getting my stock exhaust manifold ported for free off a mate.

Will one 040 do my fuel needs of 300awkw on e85? I'm keen on an intank pump, any reccomendations? 2 040's?

Cheers

The asterix next to r33 means that there are conditions... On the nistune website scroll down and read the asterix and you'll find you need to use a z32 ecu or rb20 ecu.

Z32 will keep Vct and rb20 ecu will need an rpm window switch to keep Vct.

As for fuel pumps, have you considered an 044 Bosch pump mounted intank?

I've seen plenty of r33 ecus nistuned??

he is on drugs :) no r33 nistune. Guilt toy is a big fan of the sprint 500's, he uses quite a few nowadays he may be worth a PM.

Im still a LINK fan ($1550 - 1650)

You will need more than 15psi to get 300 .... and as far as reliablity goes it will be fine as long as your tuner knows what thry are doing best ecu and setup is useless if your tuner has half a brain .... Pick a shop and see what ecu thry prefer is a good idea .... honestly the better ecu with maffless tune will save u cash on the z32 so will be around the same money if u work it out..... my mate runs rb25 stock bottom end with cams 256 cam gear gt35r turbo haltech pro pluin reloacated stock tb on factory mani for forward facing and yellow jacket coils for 344rwkw on 22psi safe tune for drifting wheel spining on the dyno in top rpm tuned by JEM on E85 hope that helps :)

I stand corrected! Wondered what was the go with the *1..,

Blitz so what injectors + fuel pump is your mate running??

Im after the walbro intank 400lph (walbros biggest) and 1000cc injectors.... Overkill for my setup?

That's going to be pretty much my exact setup. 344 @ 22 surely I'd be atleast near 300 on 15/16 with a fresh buit motor + port clean up etc?

so 3076 seems the turbo of choice? and 300awkw hard to reach on 15psi even with fresh motor, + haltec + cams + e85?

if your wondering why 300, because thats about the limit of my budget + pretty much the limit of reliable streetable driving IMO / unforged rb25 limit (yes?)

decided on 15psi (/1bar) because thats all i want to run, not really keen on 20psi and getting mad numbers, and another motor in 6 months time.

topic probs should have read "after the most power i can get reliably on 15psi

Whether you run 15psi or 25 psi makes no difference to the reliabilty or longevity of your engine (supposing that you are running a turbo within its design limits) - that's down to the maximum power, and as you say 300kw is often quoted as a sensible limit for a stock block motor, the way its driven and maintained and most importantly the tune.

Plus boost control kit, iat sensor xs harness :) wicked bits of gear

Plus boost control kit, iat sensor xs harness :) wicked bits of gear

i dont use the boost kits in 99% of cases tbh. i include the IAT for that price. Generally most guys wont need the xs harness either.

True about the xs harness. Do u not Like the boos control kits?

They are fine, i just prefer a simple wet and dry boost setting via EBC with peak recall and warnings etc. If the car has a digi dash etc then internal boost control is best.

These are my preferences everyone is different.

WTF is with all this talk of MAF-less tunes? Thought I was on a Holden or Ford foum for a sec.

As stated a few times now, youre still not understanding that no turbo is going to do 300 on 14psi. Whether you have 10psi or 30psi wound in, 300kw still has the same amount of stress on the engine. The only difference is the setups tendency to become dangerous or damage the engine. No a 3540 wont do 300 on 14psi and it would be a laggy sack of shit if it did.

Also if youve checked the RB25 Upgrade thread you would see that stock 25s can easily run 300-350 all day every day. Shit, theres a thread dedicated to it. So with your built one, im sure itll be fine at 300 if the tune is good, and youve got the added security and ease of making power with E85.

Go the 3076 and wind 20psi in. Itll be everything youre after.

He has a port clean up done rebuilt motor wont add power u still need to run 20psi ish depending as its in thr turbos efficency range dont be afraid it wont hurt it its the tune that will good tune will be fine with that power level .... he has twin intank walbro 255 pumps and 750cc high flow injectors from pj no 1000s will be fine

Never said14psi. If im struggeling for the numbers im after ill go higher but not going to 20psi. But for the sake of it, take boost out of the equation. It's irrelevant I guess anyway.

Yes I have checked the rb25 upgrade thread, but I'm after info more specific. My iphone won't show the dyno sheets + saw pages & pages of stock turbo, stock ecu, stock inj etc which I'm not interested in.

- is the tomei poncam 256 with 8.5mm lift a good choice for easy drop in mid range power? Or should I go more aggressive?

Thanks all

    • 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.
