I'm assuming you DO want more top end power than the stock turbo??

because you wont beat the stock turbo for response. :/

other options like a highflow rb25 turbo (ie. GCG) might be the way to go, steel wheels etc. and similar response to stock...

but in short, Nissan lightened the stock turbo by using plastic/nylon and ceramic components. It means it wont last as long and cant take much boost (1 bar is enough to kill it very quickly) but if the car is left stock and not thrashed it would probably suit it just fine.

If you want more power than the stock turbo can give you, there will likely be some compromises and one of those will be slightly less response/more lag.

You can still keep turbo lag pretty close to stock however...just not exactly the same ;)

gcg is garret is it not? correct me if im wrong thats just what i thougth it was. but dnt for get slideingperformance on these forums he does highflows for like 1200ish i think.

garrett an gcg are to different companies,garrett does there hi-flow for about $2200,gcg does there's for about $1700,garrett has a lot better/stronger components in side there turbo,i did a little custom work for garrett in december,

HKS GT2530 for the win. :ermm: Blistering response, I think it would be just the same as stock turbo if not better. But it does run out of air up top, I think from research it dies from ~-5500rpm, but that saves you having to go to redline all the time.

Just for an opinion, I just installed a GT-RS and running on just the HKS actuator I can't tell a difference between the stock turbo with tuned EBC and the GTRS in terms of lag.

So what is actually stronger? Because to me that sounds like a pretty incorrect statement

The GCG uses:

Garrett cartridge

Garrett wheels

Factory machined housings

The Garrett item uses

Garrett cartridge

Garrett wheels

Factory machined housings

So what parts are actually left that are different? None.

That to me suggests they are (component wise) the same thing.

Ignoring the actual spec of the turbos which is irrelevant when we talk strength of components.

The TD05 is a bitch to fit, but for what its worth - its a fair bit better than the stock R33 turbo.

A mate of mine runs a TD05 16G from an EVO 3 on his RB20DET. It DOESN'T spin the "wrong" way, has a single pulse turbine housing, spools about the same on the RB20 as R33 turbos spool on RB20s - but flows an absolute crapload better up high. It hit ~200rwkw without trying too hard....

They run a much larger turbine wheel than R33 turbos, and a slightly bigger compressor wheel - I'd say they'd have to be easily comparable with an HKS GT2530 in terms of power and spool.

It should be the same as a GT2835 with the .48 A/R in terms of power if it's from an EVO 3

      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

      By Jarsky · Posted

      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

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
