That's fine, but for the average joe blow on a "normal budget", why would you want to rev the thing past 8000 RPM.

But isnt that the point. The original poster is talking about shoudl he throw a 30 bottm end in his car. He hasnt talked about changing cams, turbos etc...so he is simply moving his power brand down 500-700rpm. he is talking about track days, not competition and just wants to do them reliably. You then talk about people with a normal budget...well a built 26 bottom end needs pistons and bearings, std crank and rods can do the job for a gob of power. If its an R32 sometimes there are bonnet clearance issues etc.

An RB30 bottm end is going to most likely needs rods as well as pistons...need sump adaptor, more machine work for the head studs,. mod dump and cooler pipes....If you want to spend the extra cash and have the extra headroom for future power mods with bigger turbos etc..But the tone of the original post suggests to me best stick with the 2.6L. He said it was responsive as is. HBut he also said budget isnt a concern sooo... present both side of the discussion

You dont need to.who said you did. but it would get there at the same time a 30 will get to 6500. 26s spin up a lot faster because of the shorter stroke thats my point

Does that mean an RB28 will get to approx 7300 RPM by the time the 26 gets to 8000 RPM?

^^ ur a funny guy!! By this logic roy has us all beat with his rb20.

All this time I thought it had to do with turbos blade tech and flow mechanics with proper headwork and correct cam choice.. f**k ive wasted my time and money

brb going to destroke my engine real quick

Your right. Roy is on the money. I bet a well set up rb20 would tear strips off a garden variety 26 or 26/30.

Takes a lot more than capacity to be a good track engine....

Plus it would sound better too

Whipper snipper? 26 cc of fury!

That will push a heavy GTR around the track like a bulldog!

    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
