Changing Twins - 2860r-5s to what?

[DougTaylor]

Do rb26's usually run that lean? 13.3 thats scary.

That's what you can do with something like the fcon vpro and a good tuner.. It 's only scary if it could lean out and the fcon and afk (air fuel knock sensor) I have won't let it do that..

Hi, Doug:

I am running a pair of Nismo LeMans turbos. There is no shuffle noticed.

I put a set of Garrett -9's on my r33 and are very happy with them. Before I had it tuned I noticed a slight shuffle as you described but after tuning it's all but gone. I managed to get 420hp on the dyno at 17psi which leaves lots of headroom for more power if I decide. I'm not sure why nobody considers the -9's as they spool faster than the -7's and can make equal to or more power.

i almost went -9's but nobody could give me feed back about them so i went with -5's and i also have minimal shuffling... just turn up your music, what shuffle?

[MattiasJacobs]

I run -7's, only shuffle i ever noticed is cruising up big hills at around 0psi. Hardly noticeable without actually listening for it.

Im running a set of R34 N1's. Direct bolt on, very responsive and a lot of fun to drive. Over 560whp with meth. Just over 500whp on pump gas at 2200ft above sea level. Absolutley zero turbo shuffle. Also thinking about going to a big single

Anybody know anything about gr2560r-5 turbos..response power shuffle??

[DougTaylor]

I'm thinking about going r34 n1 (or 2860r-7) or 2860r-9. Will consider a trade for the 2860r-5s if anyone is interested, but only if they're in EXCELLENT condition.. Let me know if you're thinking about moving up.

meth fed and turbo'd is what our cars deserve

+1 For water meth injection!

what about the new tomei arms? they are supposed to be shuffle free! Never hear anything bad about a tomei product, but i have never seen a build on here where someone used them.
