How much ignition are you running in your RB20 tune? It looks one the boost hits there isnt really much gained hp wise from more revs and the torque seems to die off real quickly.

The RB25 setup with the T67 looks the goods!

As much as it took without stopping making power... I think it was around 26 top end but don't quote me on that! Wouldn't ping regardless haha

That might be the small ports/factory intake etc holding the RB20 back, what turbo was on the 20 Simon?

Hypergear ATR43G3 0.63

Actually ended up going 517rwhp (386rwkw) without correction...

So that is a 127hp more than the RB20, plus it's 700rpm quicker to come on boost and nearly doubles torque between 3000rpm-5000rpm

Does nothing but burnouts in pretty much all gears

awesome build man nice power curve as well, and i'm tossing between this T67 vs GT35r -82r or GTX35r for my RB30det build

but i am on limited budget (2500) if you dont mind me asking how much is this turbo setup roughly ? turbo+gate and mani cheers

GTX35r are still very expensive and without exaust housing so my main choise would be T67 or GT35r looking for 400kw

I would go this any day over a GT3582R, I have a pretty low opinion of them. The will probably make a bit more power but a fair bit laggier... GTX3582R is massive so you would probably be better at looking at a GTX3076R for similar sizing!

Turbo $879

Manifold $1300

Gate $375

If you were doing a Garrett add about a extra $500 for braided lines and double the price of the turbo (GTX probably a bit more)

mebbe...but i dont buy into that snmall port thing. An RB20 has larger valve area per cylinder then an SR20 so dont see that as being the problem. You only need ports and valves mig enough to cover the displacement of each cylinder...other wise velocity, cylinder filling etc goes to crap. Probably more to do with teh lil internal gate turbo with a small housing on funny fuel meaning the thing had so much back pressure it woudldnt take any ignition up top ?!?!?!?

Not sure what the issue was, it really did hit a brick wall at that power... but I'm pretty sure it had plenty of timing top end :)

Out with the old Bride Brix...

and in with the new, Bride Zeta II :)

Was in pretty average condition yesterday, gave it a nice clean and a bit of a fix up last night and looks heaps better now. Going to try a few things with it soon to get it looking nice and fresh soon. The old Brix will end up my passenger seat when I can find or swap my drivers rail for a passenger one.

Getting ready to track the Booga a fair bit soon so thought it might be a good idea to try and drop under bonnet temps a little bit... First on the list a Turbo Beanie and also have a roll of heat wrap that I'm going to do the dump with on the weekend :)

Did the heat wrap on the dump today and finally got around to taking it for a quick burst with the new turbo bag (in the 38 degree heat)... All went really well, got back and could put my hand on the turbo bag for a few seconds so I guess the heat would have been around 70deg which would be several hundred lower than what it was originally. Dump was also cool enough for a quick touch.

The whole engine bay is now a fair whack colder, so job done. Now just time to get it back on the dyno :)

Went back for a touch up on the tune last night...

Ran a bit more boost and a bit more revs and it made a little more top end and mid range, also set up low boost for track work at 1.3bar and made 350rwkw or 475rwhp!

Here is the graph of the high boost run (note that correction being put on made a extra 20rwkw) so pretty similar top end to my last run

    • Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga
    • yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching
    • Quite right, if you make it to that pension you deserve every cent
    • 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.
