Gt35r Vs Garrett T04z - Discussion (just Post In This Thread To Create A Database)


Recommended Posts

It shows another thing as well, not everything is shown night/day on a dyno sheet when talking circuit applications.

Plotted on graphs they might look very similar, however actually driving them on/off throttle is something else again

What would be very interesting is seeing the motors held at 5000rpm with no load then stomping on the loud pedal and comparing the curves that way.

I'm surprised no one does this as it would be a great way to demonstrate transient response. Obviously the same ramp rates and gearing would need to be used for it to be a useful comparison, but I don't think that would be too hard to do.

Gccg are fitting the TO4Z 63trim comp wheel into the GT3582r and are calling it a GT3566r , I guess this is mainly for the XR6 ford turbo engines as a up grade , But i was wondering if this turbo would be a good compromise between the Gt35r and the TO4z in giving the best of both worlds in both turbos , Garrett has just released the GTX3582r turbo so that also looks to be a option , closer to a TO4Z.

I know its been a while since this thread was alive but i thought my results would spark up some debate again.

R34 GTT

RB26/30

Gt35r .82 rear

3.5" exhaust

exhaust side of head port matched and polished.

CP pistons

spool rods

9:1 comp

25psi

390.1rwkw

Nice result, which fuel?

believe it or not its on 98ron Shell Vpower =]

Never got a chance to test it on e85, especially after the twin 044 pumps and teflon fuel lines. Had a offer to buy it that i couldnt refuse. Deposit paid and the car picked up next week.

So sad =[

I never understood why people built cars like that and then sold them straight away, what is the point in spending all that money otherwise?

These things make even more with aftermarket cams, a lad I know has made >400kw @ hubs on slightly less boost with an RB25/30 with a .82a/r GT3582R on 98 :)

I never got to play with cams but judging by how efficient the setup was. Cams would of saw power everywhere throughout the rev range. Definitely worth while!

I know its an old thread but I have a question with anyone that are or were running TO4Zs.

I am finding mine a bit oil blowy with a 1mm restrictor in a -4 oil feed line. Anyone have any issues running a 0.8mm or less restrictor. I am still on a run in tune with a 5k limiter and pushing 5+ bar engine oil pressure, so thinking might have to reduce the flow even more seeing that the zeds don't like anymore than 3 bar in their feed line. Any wisdom would be much appreciated.

I don't think you should run a restricter like normal gt turbo. I'm not running 1 on my t04z and I'm not having any problems

What size feed are you running, I am thinking maybe my -4 is to big

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
