Really? I know the RB25 S1, S2 don't rev that high from the factory without a rev cut. So what lift and duration are on the STOCK CAMS?

everywhere that i have read has said that it is 7000. except for a place that sells clips which said 8900. (i don't recall which one that was, i might search for it again later)

but it seemed to me that it would rev higher due to the solid lifters and the stronger internals.

so another questions... whats the redline on the rb30 block?

standard redline on neo's is 6800, for s1,s2 its 6900, give or take when the limiter chatches it, sometimes its slightly higher depending on load.

i agree...i got my information from Rob, the owner of the company"RIPS" in New Zealand. i honestly cant see any reason why someone who specializes in the cars these types of engines come out of would be giving out false information..seems kinda odd.. if i am incorrect in the info i have presented ill be happy to retract my statement, but ill have to be prooved wrong.

His reply makes perfect sense....

If you dont know what the difference from Neo, S1 ( S E R I E S O N E RB25DET ) and S2 ( S E R I E S T W O ) THOSE ARE OLDER versions of the RB25DET IN THE R33 skyline. They have different redlines.

The NEO comes out of the R34.

umm.. i think everyone in this thread knows that.

what does not make sense is how the rb25det NEO would be 100 RPM lower than the rb25det s1/s2 when the NEO has solid lifters and a stronger bottom end.

please prove me wrong.

Well with the solid lifters you would be able to raise the rev, stronger bottom end or not. And I'll secong that we all know that the NEO is from the R34 GT-T

R34 GTT (RB25 Neo)

Let's stop all the bickering back and forth about the redline.

just bc its red doesnt mean ****. Panges who had a neo confirmed it was 6800 rpm. What does it matter anyhow, any dyno graph you look at from a standard rb25, the turbo stops making power past 6400 rpm anyway. No sense reving high for that. If you modify the motor with a new turbo, most people increase the redline anyways. I dont see why this is even a big deal. If you want to rev buy a honda.

the turbo has nothing to do with your redline. and i am not necessarily asking about the factory redline. i am asking what the head of the rb25det neo is capable of.

i am not talking about a factory setup. so get that **** out of your head.

if you don't have something intelligent to add to the thread then don't add anything at all.

so when you asked what the redline is for the neo, you meant a fully built rb25 with special initial D head so it rev really high?

well after you practice your dorifto, youll see that the redline is 12,000

um ill add something intelligent

RPM does not equal horsepower

and your redline will be set to the limit of your walet.

What are you asking stock ecu rev LIMIT or theoretical mechanical rev LIMIT?

Maybe if you asked that question at the top of your thread unstead of leaving it extremely vague your question what have gotten answered much faster. Check out SAUS they arn't a whole ton of people who tinker with the neo. Im sure some are reving theirs. Like I said before tho, you dont want your redline to excede much further than your motor's power band.. ie a few hundred RPM's.

Oh yea, not to mention the extreme abuse placed upon your transmission under high hp, high reving shifts...

good luck.
