What Have You Done To Your Stagea Lately?

[RubyRS4]

Fitted 575cc injectors to the Stagea today, along with a new Z32 AFM to complement the Garrett 3076. Tomorrow after work, I'll limp her to the tuners for a new tune on the Nistune ECU. Should pick up a whole heap of power.

Then on Saturday its off to the tyre shop for a set of new rubber and a wheel alignment.

Just in time for the track day on Monday!!!

off to watch targa tasmania

Had a busy day on the Stagea today... Had 4 new Falken 912 tyres fitted today and a 4 wheel alignment. Think these will be better than my cheap RV tyres.. lol

Also made a little mod to the blow off valve to block off the small hole to improve boost response.

Can you elaborate Andy? Sounds easy to do, does it make a difference?

[Sunkist]

to the BOV or the allingment.

In the BOV there is a small hole that allows the air to bleed unregulated. That is the hole I filled.

After 1 day results are, certainly comes on a little stronger and build boost a little faster but at a price. Throttle is a little more stuttery but not a problem BUT I have the Turbo making a loud noise. Not sure what you call it but it but like a high pitched and quite audible around.

I am going to try a little mod today on it today and will let you know how it goes.

noise when you release or on boost?

yup

yeh it used to do that before a tune but not as much... its surging..kinda sounds like the BOV gate isnt opening at all though which is strange.

once the tune came its went to a sharp phiewsshhhhh sound.. ill try record it on the way home n upload.

maybe a temp fix is a 2mm hole like scott said.?

That is the plan today..

Could well be that my BOV needs a bit of TLC...

[Sunkist]

keen to hear results.. mine had oil in it the other day..

let us know

[zei20l]

andy did you put the vacuum hose back on the other side??

[Sunkist]

andy did you put the vacuum hose back on the other side??

i've dont this before.. the gate opens at about 6-8psi and you hear a shhhhhhhhhh on accel.

it actually doesnt flutter, seeing as its already opening.

All lines put back in place...

[spoolin12]

I put a 2mm hole in mine a few days ago. Made no difference.

[Sunkist]

surges like the above sound clip?

maybes its a tune issue?

[zei20l]

tune issue for surge? nup

i rekon its throttle speed related. maybe the factory/impul doesnt close the throttle as quickly, or maybe much faster. i get a tiny bit of flutter, but i also think its due to BOV placement in the inlet tract. if it was before the FMIC the pressure wave maybe wouldnt be created?

[Sunkist]

it doesnt surge at all on mine or scotts though?

you can hear the valve instantly open and air rush through it..

Edit: Get craig to do it and see what happens.

[zei20l]

well, its mechanical, no amount of tuning can change that

however, being a valve that uses the pressure difference of the throttle body to open/close, thats why i put it down to ECUs.

at lower RPM you have throttle limits, andys may limit it differently. his may slam the throttle shut when he backs off, or maybe its more gentle.

andy put your stock ECU back in and go for a drive. see if it does the same thing

completely forgot he had an aftermarket.

or tell craig to get off his lazy ass and do it! lol

but Iain, mine and Scotts used to both do this before the tune..mine not as much as the clip, but none the less, it did.

once we tuned it stopped?

[zei20l]

did you increase boost when you did the tune?? the boost could push the BOV open and assist with venting the air through the valve
