Everyone, I am interested in seeing if this turbo really is a bit of a lag monster, or this fella has just set it up wrong. I am willing to put in $10 towards his dyno time with Trent.

If we do this properly, I'll gather the cash and send it directly to where he takes it (Trent from Mercury, or am I on another planet?) This way, its fairly legit. Plus, I ran a $5k group buy a few years back, and made a lot of friends, so you can trust me. Plus, its only about $100 or so.

Anyway, I am happy tpo help out. Its also going to save me thousands if I decide to take a risk and end up buying a turbo that is laggy, or not suitable for me.

Anyone keen in helping out this test?

If we go ahead, I want to know A LOT of info about your car mate so Fill in this form form

Engine:

Intake Manifold:

Exhaust Manifolf:

Cams:

Compression Test:

Fuel:

Intercooler Size:

Pre intercooler piping size:

Post intercooler piping size:

Full exhaust specs:

Dyno Chart with AFRs plotted:

Full Ignition Map:

Base timing:

Type of ECU:

Anything else I Can think of over the next couple of days

I know thats a lot, and maybe it will take you a while to get the ignition timing down, but hey, if you want a pretty much free diagnosis, work for it, haha.

Fill this out please.

I really want to see this turbo tested properly. I cannot recommend it to people (I'm a tuner, and I get a lot of people asking me what they should buy) if its not what garrett claims.

Thanks, and I hope people are interested.

I have answers to all those except the ones that are obtained from the dyno run. Af ratio. Timings etc.

Trent could sort those out for you. Fill in the rest now to give us a better idea of possible restrictions. Whats the intake like, do you have any pics?

Its a avo airbox. Like the custom ones u see in the corner. Steel. Pod inside leading to front of Turbo. Steel piping.

Engine: rb25 series 2

Intake Manifold: standard

Exhaust Manifolf: standard

Cams: standard

Compression Test: -

Fuel: 98 octane.

Intercooler Size: need to find specifics.

Pre intercooler piping size: 2.5 or 2.75 (just fits through factory holes under airbox)

Post intercooler piping size: as above

Full exhaust specs: xforce 3" Turbo back. Stainless. Highflowed cat (3")

Dyno Chart with AFRs plotted: -

Full Ignition Map: -

Base timing: -

Type of ECU: Link g4

Has Trent agreed to look at the thing for $100? Start there..

Nah 120. I got a reply SMS.

When you say x-force turbo back, surely you do not mean an x-force turbo back....

X-force do not make a GT30 specific dump pipe, nor would they make one thats GT30/skyline specific. If your dump pipe is an X-force item, then you have a factory shaped dump... And that means we know what rear housing you have also...

Please confirm your dump pipe and take photos of its exit from the turbo please.. Please confirm who supplied the turbo for you too.

Had xforce dump on standard Turbo. When I changed Turbo avo had to mod the dump pipe to suite the garret hotside. So it is an edited xforce item. Im definately running. 82 garret hot side.

straight away I say ditch the "12psi" actuator and purchase a proper heavy duty "1bar" adjustable Garrett turbo actuator. they cost around $120

should make a slight, but positive difference, to the spooling up of the turbo.

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
