Hey guys.

Can I run 264 9.00mm lift hks cams 2202 RN175 with standard valve springs. Where could I get these cams in Australia?

That's a reasonably high duration, meaning you will be revving it.

In which case you will probably want better springs.

You can run an adjustable exhaust cam gear with stock cams, which will give you an improvement in mid range power. But as a mechanic id never fit cams without putting in heavy duty valve springs. It pretty much goes hand in hand. You want cams, you must fit valve springs. Yes the HKS cams are drop in meaning they'll be ok to use with your stock valvetrain/head (excluding valve springs) The stock springs wont cope with the duration/lift of the HKS cams.

I hope you don't want to put in cams just so you can have am adjustable intake gear.....

That would be an ultimate fail, as vct is way too good to lose, and the stock gear is adjustable anyway (on a neo that is, not sure on pre neo, adjustable from the back but easily modded to be adjustable from the front.)

Why do you want cams?

What do you use the car for?

i had hks cams before and i want to delete vct ro run 26 covers. I want the car to make around 550

DONT DELETE VCT.

Especially just to run 26 covers.

That's plain stupid.

People with rb26engines would kill for vct.

Yeah seems silly to get rid of it just to run different covers. You can make the 25 covers look good

Or you could probably get the 26 covers modified to have the hump for VCT put in them

The power will be alot nicer if you keep VCT

      Fixing exhaust position?

      By PranK · Posted

      I once hit my knee on an exhaust on my sisters Suzuki Sierra after she drove it her *normal* way. My knee looked like porridge for weeks. Bec and my daughters never go near this car. I can see one of my dogs losing an ear though. 🤔

      Nice, love a good GTS-t.  IMHO the factory body kit with the 'aero' front bumper is perfect. Can't improve on it unless it's a GT-R. But it looks like you changed it to the normal bumper?

      Easy solution to both of those. Put a split bit of garden hose on each one. Attractive and practical!

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

      So I guess the next thing to do will be to discuss whether to create a new section of the forums to hold the library (boo hiss?), somewhat undoing the recent tidy up, or if there is a bolt on wiki module for Invision? (I must profess ignorance as to what has been done, what it might cost, etc. I have only briefly googled and seen discussion on adding it.) Or is a wiki even the best way to do what I'm talking about? It possibly isn't. Given that we're trying to re-display forum content, it probably needs to be presented as forum content in forum format, and a wiki would probably struggle with that. A wiki might still be the best way to do some other things, so I'll keep the idea simmering if we don't use it here. Back to the library as "part of the forums". Would we do a single new library? Or put a library thread in each section? Pluses and minuses for each of these, surely. Would we do as I originally suggested, and make the first post in the library be the total of the library, with any reply posts just being the inputs and suggestions I originally posited? Or would we allow posts to accumulate one after the other, each containing additions to the library? Maybe the first post is still an index or something. It's all sounding horribly more manual and messy than my original brain fart. But I hope there's some other good ideas floating around - because every time I come up with a new one of my own I immediately see problems with it.

      Tips look fine to me......but Boring stuff: Legalities - Vehicle standards notes that exhausts cannot extend to a point where they could cause injury Scary stuff: Mrs cuts open her shin putting stuff in the boot (ensure you have some bandaids and shiny jewellery handy)
