Could any of you blokes let me know at what level the std RB26 conrods tend to break.

I'm pushing high 300's with my GTR and the tuner said that on e85 the torque produced could be too much for the std rods to handle.

the motor has forged pistons etc but i left the rods std because when i had it built i didnt think i was going to attempt to push for 400kw

standard rods will be okay its more an issue with the rod bolts... when it was built did they upgrade the bolts?

keep the rev limit sane and don't let it detonate and you should be okay

R34 GTR

Autronic SM4

Injectors

T04z turbo kit

Exhaust

Fuel pumps

Nitto head gasket

Drop in cams

STANDARD BOTTOM END

450kw @ all four wheels.

Does e85 help with engine longevity? The higher ron is much safer right, but the higher boost probably alleviates the buffer gained with better quality fuel.

If you didn't up the boost and ignition it would, but everyone does up the boost and ignition so the extra buffer is now gone.

T04Z/33psi/450 @ treads on E85 is an interesting result. Guess that shows the difference when people build motors and pay attention to the small things that overall make up the bigger picture and allow you to make such figures with 6-8psi less and on PULP.

Well its Sucrogen E85 - so not the E85 you or I would get from the pump, nor is it the same price (roughly $2.5/L IIRC)

Do you remember the Sucrogen rep/owner or whatever that came on here and blew up @ everyone a while back? lol... Cause it's the same mob if memory serves me correct. That was a good thread. I should try find it for lols.

First price I got from Tas was about $350 return.

That'd probably include a trip to syd and back, or do they fly direct from tas?

Not to mention that you'd also need to have no luggage, leave at 4am, have even smaller than normal seats, etc.

Hi there, got my car tuned today at Pits on the gold coast.

Mods as follows.

R32 GTR

RB26 bored, decked, cleaned, balanced and the crank ground.

Ross pistons, total seal rings, Spool Conrods.

Head is mildly ported, re-seated etc etc, Tomei 270 dur 10.8 lift cams, Brian Crower springs.

N1 oil pump, tomei oil restrictor.

1200cc injectors, 2 x 044 pumps, 3L surge tank.

Haltech E11v2

STD coils at this stage

115mm intercooler, chinese one i'd say, $400

70mm Billet turbo by Mark at Mr Turbo, Gold Coast

60mm wastegate, ebay cheapie.

4 inch exhaust all the way with 1 straight thru muffler.

twin plate OS clutch.

Tuned today on E85 from the pump, made 564 Hp on 26 psi, 528 hp on 23psi, and 501 on 20psi.:cheers:

Maxed out the injectors at 26 psi, looking at ID 2000's for the next tune. hopefully crack 600 which I don't think will be a problem.

So I went to the T and T last week and ran a best of 10.9 but at a whopping 138.5 MPH, needless to say they booted me out, but I was happy!!:action-smiley-069:

stock box ??

Yep stock box but it's not happy!

Had to be nice to it on the launch (if you call 7K nice) but getting into 3rd was a struggle, hit the limiter right on the 400m mark in 4th gear, Limited to 8300 rpm

Im looking to sell the car soon but would like to see 650ATW with Id2000's first, If anyone is looking for a good GTR it'll will be around $25,000 with new paint.

The car is well built and will be reliable, (apart from the g/box)

    • Hi, i’m making a rb25det coil loom for Vag short coil. Can anybody tell me which Ecu signal wire belong to coil number 1 and 2,3,4,5,6? The connecting switch in above pic is 8 wire i think white is for +12v and black for earth.
    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
