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

    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
