Thanks for the reply! Wish I had have known that back when I was doing my build (2 years ago now!). I'll definitely keep it in mind if I ever pull down the motor again. Have you got any idea of the power they can handle? Cheers, matt

Gradenko - out of interest - how much work is there involved to fit the chev rods? And if you don't mind me asking - what did ya pay for 'em? Cheers, matt

I did this to my Skyline about 2 years ago... Response is only marginally worse, and the car made an extra 20-25rwkw (this was with cooler,pfc,exhaust,etc). Peak power was 206 rwkw from memory. IMO - If you're pulling the turbo off yourself (like I did) then it's a worthwhile thing to do, however if you're paying someone to do it, save a bit more and buy a turbo that gives you more room to grow. When you have 200rwkw - 200rwkw isn't enough! Cheers, matt

The same sort of thing also applies to "high-flowed" injectors... It stuffs up the spray patterns.... Cheers, matt

Riceline -what's the prob with your car? Cheers, matt

Hrmmm - that was just what my mechanic called it... Dunno the specifics on it, but I know it was "slightly" thicker than the normal ones... My mechanic said he'd never come across them before... If I remember correctly, I think the Nizpro guys said the limit for stock rods is around 500-550 ft/lbs of torque... Run less than that, and they're fairly reliable, much more than that, and the chance of bending a rod goes up exponentially. Cheers, matt

I know of a GTR making near on 400rwkw on stock rods (racepace dyno) which have been running in that tune for quite a while. It should be running @ Calder tonight. Not sure whether that car is just a freak, but it gets track raced very frequently, although I think that's running less boost at the track. Emre & PH1's GTR's both make over 340rwkw and have been running around for over a year without any probs... In any case, I haven't heard of anyone bending a rod on a GTR motor. Cheers, matt

Nah mate, I've got a RB30 bottom end... The static CR would be too low with GTR rods! I've just got shot peened, nitried rods... They are series 3 VL rods though - apparently they were slightly thicker at the big end than the series 2.... Doubt that's gonna make it much stronger though... If I decide to hang onto the car, I might pull it down in 6-8 months time and stick in a set of aftermarket rods and bump up the rev limit to 8000... Cheers, matt

Ouch! 1 month? Mine's been running for coming up to 2 years now with around the 320-340rwkw mark (depending on which dyno you put it on)... I'm only running around 16psi and it's rev limited to 7500rpm. I was going to start upping the boost to 20-22psi, but after hearing that, I think I won't get greedy! Cheers, matt

Good topic! Has anyone done any testing on strength of the RB30 rods? From what I've seen - it's not generally the amount of power that'll kill rods, it's torque... Hence why a single cam RB30 won't be able to make as much top end power as a twin cam... Cheers, matt

LOL - That's the story of my life! matt

Yah true - but yours is a custom manifold too! matt

Nahh - not true at all... My turbo's a low mount! matt

Mentor even! Bloody can't get this freaken clutch... At this stage, it looks like I'm out for this weekend matt

That was with slicks too! matt

Oh yeah, stock manifold too matt

SXX (Ange's car) ran a 12.05 @ 114mph about 2 years ago with a T04b (shitty turbo)... matt

It's about 0.7429 kw per hp. And 1.3462 kw per hp. Cheers, matt

Quiet you! matt

And that's exactly why I ain't running slicks! Ouch Yeah, I've got nittos to run on, so when I get my new clutch I'll be going out to see if I can run mid-low 11's. On street tyres there sweet f/a traction below 120km/h (or a bit into 3rd gear).... Ahh well, good luck with that... As you said, stay off slicks for a while and see what she'll do on nittos. matt

Maybe on a yank dyno! Nahh, they're generally good for 500-550hp. Cheers, matt

Nahh - T66 is a little bigger than a 3040... Good for about 650ish hp... Cheers, matt

Umm - It's a T66 with yeah, Rb30 And Dandin - yep sure do buddy Why... You wanna tryme? matt

Fairy nuff! So when r u running it next? PS - Snapping an axle... F#$k... Which side? matt

look at my sig... 12.3 @ 123.5mph. That was on ST115's. ie... Shitty street tyres. and a 2.4 60ft time... Why'd you ask? matt
