This here is my unopened rb25. Has a surge tank,

044 pump, 750bosch injectors, e85 fuel and an apexi

Power fc. Turbo is a hks 3037 .63 rear housing with a

Garrett front cover. Tuned by smmotorsports making

344.1rwkw on only 15.8 psi. Since October last year

I've done 5 drift events, Phillip island sprints and

Winton Vic time attack over Easter. Engine still has

no signs Of wear.

Hmmmm interesting, my car has tested the limits of that turbo in every way and with a 0.82 rear on the same turbo with every supporting mod possible the best we ran was a 320-330kw...... 344 required 20psi bleeding to 18 and that is with the bigger rear housing!

yeah, I think we can conclude it's a happy dyno, however it's definatley a 300+ car and would be an assload of fun

Yep not doubting that part! It is an awesome combo and tried and tested many times! Good result and welcome to the club haha

Good to have people around who are willing to try and test combos so you know what works :D Your car has become a bit of a benchmark for the GT3076R's ability, I reckon!

Well we have found the limit with this combo and will be looking to improve where possible, the 3076 and RB25 were made for each other :yes:

:ph34r: swap it for Hypergears VNT and get 400kw.. do it!! :yes:

Not convinced on that as yet! Good result for sure but there are other ways to make power on mid frame turbos! You should know, you are about to try ;)

srsly?

it's written on the chart :P

:laugh:

I know i'm probably going to be shot down in a ball of flames for this.... but is there any real point in shooting for 400?

surely it's just useless power unless you have a very very good and expensive setup

@ 320+ rwkw in a 1.4 tonne chassis I needed to run NT05's just to have a hope of traction, and on your average tyres it was already game over.

seems to me like it's just inviting the motor to pop for power that you will never use beyond a dick measuring contest

No need for flames, it is a pretty decent comment and something i have also said in regards to my car... My tuner was saying i should go to the 35r frame turbos but i said i was overall happy with the performance....

Overall i think mine needs a little extra spool and maybe more in the top end for drag and long open circuits.... For street and hill climbs i would be running gate pressure anyway so it gives you all options.

My car is only running RSR 265's but once warm i can start to get them to grip up, of course i cant launch the car on them but that is where MT tyres will come into play!

As an all round car to do all events i dont see boost settings allowing 330kw, 360kw and 390kw to be a problem as you cover all bases and still have a damn fast car!

Of course bragging rights too :P You know, coz racecar!

I would love to have more because i can! But the old 3037 has nothing more to give! I will continue to seach for a better way haha

Finally some results. Slap us with a teaser.

Haha yeah some results for you finally! And it went over 500rwhp as planned ;)

Well the meth injection is finally installed after months and months.

Was hoping to join the club but might fall a little short of 300 :(

Looks like the old 2835 pro s is maxing out and we have had to tune to fight off knock rather than outright power.

Back up to JEZ tonight to finish the tune and try a couple of things (cam gear adjustment, adjust afr etc)

You never know, I may get there buy I am a little doubtful.

Ah damn! Well i hope it goes well! Shame i hadnt picked mine up from its tune today or i would have popped in and said G'day!

I stay in this club with 390kw :woot:

    • It makes you wonder, all these people starting to make a billet replacement head, I wonder if any have thought about trying to adapt tech from newer engines into them. You're already at the full design stage to make a billet head... Why not really spice it up and had some more modern tech into the mix too...
    • Connect all the plumbing up properly. The actual worst part about having the turbo unable to actually build boost, is you can and likely would over soon the turbo if you drove the car (free rev while stationary isnt likely to manage it).   If you do have an air leak as Duncan suggested, you'll have a bad time as the AFM will be saying different to reality.   As you have had the engine out, I'd go over all electrical connections again. If you have a consult cable, plug it in, and see what the ECU thinks is going on. Did you touch the timing belt? If so, double check your timing on the gears is correct AND put a timing light on it while it's idling and see what ignition setting you have. Is the AFM you've installed the one that was in the car previously? You said you replaced seals, what seals exactly? What have you had apart?   From memory when I had my RB25DET with factory throttle, there was two plugs the TPS plug on the loom could go to. One would leave the car running like shit, the other made it work, I think one plug on the TPS area was for something else (an option). It's too many years since I saw that part of the loom to remember properly though.   Is the car idling smooth (as smooth as an RB can)? Does it smell fuelled up?   I have a feeling either timing in timing belt is off, or a sensor isn't right.
    • Theres still skid pan and motokhana days up in QLD at least that are $100 or less. The ones that are ran as "driver training" less so, they're expensive, but just normal skid pan days like SAU ran are still low cost. And thats one of the places I learned to be a lariken, purely by asking for passenger rides, and how people were doing crazy things. Reese gave me plenty of pointers back in the day for skid pan! And yes Duncan, I will never forget your pointers for track work. Especially after Neil got out saying "I am NEVER getting in the car with him again!" 😛
    • 49719 is the cooler loop. Right at the front, LHS of that diagram. Return line from rack (LP side) goes to cooler loop on RHS front of car, then back under engine and returns to bottom of tank. 49717M is feed from tank to pump. HP line out of pump is thick rubber, followed by the hard line that runs down to crossmember and runs in parallel (but opposite flow direction) to the LP return line. Nothing goes anywhere near the firewall or interior of car. The closest they get to that is the connections on the rack.
    • Thanks, plan is to drain all fluid tomorrow and do smoke test to find out the leak.   Appreciate your help and want to understand how the system work. So cooling is achieved by the long loop not any rad? The diagram seems to suggest it connects to somewhere inside the cabin and I thought that is a cooler inside firewall. If you look at the diagram it seems to show it connects to something inside firewall. I tried chasing it but not easy unless I take loads off   i am confident pump is good as fluid goes in and it gets soft( steering) but as soon as I turn engine off , loads of bubble come to surface and overflow. When engine is on , fluid level is below minimum but when off it shoots off and thinking it is sucking air in. I suspect aluminium pipe may have a crack line or whole   smoke test with no fluid should be a good start and if needed will remove the pump   In addition, the one going under the engine bay is high pressure line and one directly connecting from pump to resorvoir is return/ low pressure?   finally I searched and suggestion is to use dexron 2 but that is discontinued so bought dexron 3 as all research suggest it is compatible and shouldn’t cause any issues/ blow seals. I bought two liter of dexron 3 motul atf
