You ricer Roy! :) Going for the 'sound' rather than anything else! :ermm:

If anything i crave the RB smoothness. Sounds and feels cool but after a while I get sick of it, like a atmo BOV if you know what I mean.

Was thinking, u want a rough idle, just lean her out a bit to the point where it starts missing at idle load points. Then you get the shakes and misfires and general farting around that you're craving for lol.

Oh yeah 9krpm's 272s sounded pretty damn tough on idle. Probably too rough for a street car I'd say though.

You make me laugh :bunny:

The only time i've heard an angry RB is when there are some large cams being used like in Daves car... and the old Jet33... Jacks car has a very slight difference but not major

They werent 260/8.5 though :O

Jacks car sounds awsome, but not too cammy. Has a slight lump. The 280's i have on my car though. Fark that sounded angry. Oh the memories :)

There's some really good ideas in this thread. Have you tried feeding your engine banana's instead of 98?

Aiiee, the good ol' banana in the tailpipe.... although I've heard that since moving to Melbourne Troy's been getting a bit of the banana in the tailpipe... and enjoying it! :(

I have HKS 264s in my R33 GTS-T and have a mild lumpy idle, and yes making leaner will make it sound lumpier.. I made mine a little richer as neighbours were complaining about exhaust noise.. but will change back when I get my quieter twin system ;-)

Good midrange too...

options as i see it:

- some expensive, but high-lift cams

- ej20 conversion

- wire up a switch to cylinder #1 and kill the spark when at idle

- record the noise of a 427ci engine and put it on CD and play it while driving

- make the noise yourself when driving and convince your passengers you're not crazy

hope you find a solution :)

...well how else am i to get this money togther for the "GTST of extraordinary magintude"

And thanks for all the informed responses hillbillies :ermm:

mate, you will find even the 260/260 poncams can give a quite lumpy idle. it's in how it's tuned and how the cams are dialled in. even my GTR with stock cams but adjustale gears has a bit of 'funk' to it at idle. Nicks GTR with poncams and cam gears is very lumpy at idle.

troy the count is on your side. a nice lumpy idle is the go. do it.

    • That R31 was so cool. Only did Orange Park once. Scared the hell out of me.

    • The alloy coolant reservoir has a sight glass, so as long as I can see coolant in the sight glass it's GTG, as for PS, it isn't anything catastrophic if it gets low, and as it hasn't lost a drop since I have owned the car I cannot see it being an issue, even after putting the "big block" 2.5 in....LOL The only time it gets slightly messy is at oil changes, as the oil filter sits above the frame, and I need to use a plastic bottle with its bottom cut off to catch the flow when loosening the filter
    • Good on you for taking on the job, but it is a big one. Even if you have bolt on manifold and turbo, you will need: Post throttle pressure source to boost controller to wastegate (and FPR, and ECU/MAP sensor) Pre throttle pressure source to top of BOV(s) Oil feed - you can take that from the standard port in the middle of the block Oil return to block under the turbo - this is much trickier than it seems to route a decent/wide pipe past the manifold. You really can't use rubber hose because it is way too hot there, and also the oil out of the turbo core is a bit frothy so it needs to have a decent diameter Water feed - you can take that from the standard port in the rear of the block. Water return - mine runs to a T into the heater box return, just make sure you don't create a high point making bleeding hard. All of those lines should use 200 series style teflon braided hose with heat shielding because everything needs to be routed past the manifold. Also a turbo beanie is a really good idea to minimise the chance of the car catching fire (under bonnet lining in particular) You also need to decide a cam cover breathing solution as well, will you vent externally via a catch can (probably illegal) or return to the intake (plumbing required and can oil up everything over time) Keep in mind the intake and exhaust piping in the engine bay will be custom so you either need to be able to fab ally and steel or have someone you can get a car that isn't running to. Get the wideband fitting welded into the dump pipe at the same time. Also, just my opinion, a screamer pipe attracts attention and doesn't add power, I'd plumb it back if you want to be allowed to keep the car on the road. BTW do you know anything about how healthy the motor is, and what power you are targeting? Doubling or tripling the factory power on an unknown motor is a little risky. Also fuel system will need some attention (pumps, high current hanger, direct power and earth feed, injectors etc)
