i dun wanna start one of THOSE threads but

It's all in the tune and how you choose to abuse that power. a 300rwkw standard bottom end rb25det in a drift car wont last that long. where as if your just in it for the thrill of things as a daily, easing on the power the motor could last for years. reving a standard rb25det anything past 7500 spells trouble. It's not worth smashing your motor and letting the motor distroy the things around it. My mate did his bottom end in an rb30 and it distroyed his head and his turbo.

I saw a 595 rwhp rb25 on nitrous. It lasted a few months I believe. I think you could pull off a 500+ rwhp RB25 with a stock bottom end for quite a while if you tune it correctly and it doesnt see redline 100x a day lol.

I've heard of a few other 600 hp rb25's but that is the only one I clearly remember.

Not to thread jack, but does anyone know the record high hp on an rb20's stock block? Just curious.

some let go at 250 some let go at 300. you have to remember that these engines are starting to get a touch tired now and a lot has to do with your tuner, i would aim for say 280rwkw but if it then blows dont be suprised

      I should note too as I have all 4 wheel speed inputs to the emtron I now have the emtron controlling the attessa solenoid for 4wd/traction and launch control strategies.

      It works quite well with the adjustibility within each of the programs of the turbolamik. Essentially p1 is drive and lockup comes on like a normal driver.  But in program 7 I have customised it to not request the lockup clutch to engage until something like 6500/7 when slip was the lowest.

      Use text replace function to auto-link to referred threads?

      Yep, I like that. The tags are only on the first post of a thread and we don't get huge numbers of new threads. Also, I plan to add some more report types and we could have a member report type like 'review tags' then members could flag if they thought a topic wasn't tagged correctly.  No way man, I dig the input. Thanks!

      It's a valid thought. There's not exactly that functionality already (when creating a thread) - that's where the OP can use/create any tag they want. We'd have to come up with a way for the user to request their tags get reviewed or something. Otherwise the mods would have to review every new post's tags (for those that have them, anyway). There's kind of that functionality already exists to some extent, post facto of starting the thread, where the OP or any other user could report the post to admins, and request that tags get reviewed. We could do this already, and any user could already have made such a request. To make it a part of the forum proper, it would require an initial and an ongoing education programme, so that people know that it's a thing. OP based tagging/request for review would also require at least some (probably most) of the user base to be told that it's a thing they can do. Both of these things probably wouldn't spread too far and/or get used very much. If it was the standard approach on a lot of different sites, then it might do, because people would be used to it. Prank's approach to this differs from my original thought, by leaning into tagging. Which is fine - it's possibly better than what I originally suggested. In fact, I just went to the R32 GTR wiring diagram thread and added tags, including "Library". That's probably a good way to use tags and the idea of a library. We just have to drag together an (organised!) index of threads or posts that have that tag. I have yet to do any of my own follow up by pursuing worthy threads and posts and reporting/marking/tagging them for the library, such as the @Sydneykid stuff I was talking about, and possibly any amount of @Lithium 's and others' posts. At least if I tag them Library, we'll have a start.   Back to @Wazmond's idea as it relates to @PranK's, we might have some sort of a list of tags that are already used to scrape for this library. I'm not entirely sure how that would be presented or used, particularly if it got long. But it's yet another idea!   cheers

      Just a thought, but instead of restricting, is it possible to do like an "up for review" kind of thing? Where say someone who's not an admin/mod tags, it would require approval for it to actually tag? User posts with a 'tag' > Admin/Mod Reviews > Approves tag > Tag now exists kinda thing? Just came across this thread so Im not too sure if Im straying off topic or not but forgive me if i am...
