Hi guys, i just want your opinions on what you think a t04r would go like on an Neo Rb25det??

At the moment it has a stock bottom end which will later be forged down the track and it is mainly a street driven car, do you its too big?

Cheers, any comments will be greatly apprieciated.

Is it the HKS version?

To my understanding the T04R is a trimmed version of the T51R.If you want to go big the better option will be the T04Z.

But on a fairly standard 25 IMO its too big.

You will benefit better from a GT30 or GT35 for a street driven car.

Can get back on the details if you like but from memory a T04R is simply a T04 "P" trim turbine driving the BCI-8D compressor that the T04Z turbo uses . T51's use the same ball or bush bearing center sections as the T04R/T04Z's but the turbine is larger again - vaguely similar dimensions as a GT42 turbine but older "T" series wheel tech .

That's a lot of turbo for a hydraulic valve trained RB25 especially if it has std pistons and single throttle inlet manifold .

IMO if you had to have one the ball bearing T04Z would be the durable solution (turbo wise) but I think its too much for an RB25 .

Arguably a GT3076R or GT3582R is a bit more in proportion with what can be reasonably expected from the RB25 top end and 2.5 liters . Maybe if you were prepared to fit a 26 head and inlet ...

Cheers A .

    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
    • That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
    • I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.
    • If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
