RB30, potential auto choke issue?

[Throbbinhood]

Thanks for that, I have thought about 35's but I always thought they were a touch too big for my engine, although your experience with it being ok is interesting, I may get a set of 33's and wish I'd gone 35's. Do you find any serious negatives, acceleration, braking, fuel economy and crawl speed in low range?

I don't drive it like a race car, but acceleration still seems fine to me for a big car. Braking I certainly noticed a difference, but that just required a slight driving style adjustment. She still pulls up if I really put the foot down. Fuel economy, on the highway I get 15-17L/100km, depending on the area (hilly hwy/vs flat). She sucks at keeping 100 up the hills, but she sucked on 31's too. I find if I gear back to 3rd and hold her at 3500 she'll sit on 90 up most biggish hills. Crawl speed in low range can be a little sucky. I'm still running the std 4.3s. Being a manual, going up steep hills, and trying to do it really slowly, isn't too ideal - especially with the rb30's tendency to stall in the steep stuff. That said, I've done a fair bit of high country stuff and it hasn't been an issue. Steep downhills are a bit more of a pain, but having just tinkered with my choke stuff bringing my idle back down to a normal level, I'm hoping I get a bit more control at lower revs.

Haven't had this rig on 33's, but love the 35's and the positives, in my eyes, far outweigh the negatives.
