Ive read through endless pages of dyno graphs and comparisons, ive even tried a few combos my self. but im after peoples recommendations as to what would be a good, over the counter purchase to put on my RB25.

I want around 270-280 with awesome response, with the potential to go to 300 ish. Turbo will be in a high mount application and more then likely externally gated.

i have previously run a gcg 3071R with .71 avo rear housing in the low mount postition internally gated and made 280 rwkw with cams and gears. wasnt a bad turbo at all. but i still felt it was a bit of a compromise being internally gated as well. boost control was an issue with this set up.

so yeah... post some suggestions people.

Cheers

Simon

find out what troy (roy) uses on his rb20 and run the same setup on your rb25det

from memory its a td06 from a GTR twin kit run in single form on a proper manifold, external gate

its here

yeah i'd love a TD06 20g, one of my mate has one on his 25 and makes 317 rwkw on 17 psi. awesome response too. however at 4K for the kit its a little out of reach.

after a garret option which would be cheaper yet still effective

You could either wring the neck of a GT3071 (with a 0.82 rear housing) or GT3076 or perhaps something in between like discopotato 03 just ordered ie 52 trim 76mm.

If you have a split manifold you could order a divided housing from ATP which might improve response slightly and would suit any of these options.

For about 280rwkws with fast response you can try a 52T 76mm comp on a GT30 Turbine in BB assemble using .63 rear housing. Or .58 rear housing which would definitely increase response shaving off about 20KWs top end power. You can also replace the standard .50 To4E compressor with a .60 T04B comp. Which can also increase turbo response.

have thought about tuning for E85 but availabilty issues is a concern for me as sometimes its not even for sale in SA. that and the fact for 300 rwkw i'd need 740cc injectors or bigger!

limpus: the 3037 pro s would be my ideal choice for a turbo i reckon. how much you asking?

I was thinking about this last night, 4k for the td-06 kit seems cheap when you consider what it comes with compared to a custom garrett setup.

this is a rough guide, for what I would do with a garrett setup, obvioulsy cheaper if you buy a china minifold.

decent manifold - $1200

turbo - $2000

wastegate - $500

oil and water lines - $300?

Custom Dump - $250-300 in mild steel

intake pipe- anywhere from $10 to 200

Mind you, if you can get a td-06 kit for 4k please let me know where lol

yeah thats the thing tho, exhaust manifold, dump, intake and oil and water lines i do not need to factor into cost as i'll be doing them all myself. So just need turbo and gate really.

that RX6 kit looks insane! lol

      R33 Fuel Pump & Brakes after alarm swap

      By GTSBoy · Posted

      Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option
