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:

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
