VTA will be grand so long as it's a good spring in it to keep it shut. Ideally you'll get a little chatter from it at low boost (like 5-7psi) and then proper dump at full boost. There's no real mapping for it on a standard ECU - the air that's vented is lost and the ECU adds the fuel for it anyway (unless it's still in closed loop in which case the ECU compensates when it sees the change in mixture at the o2 sensor, then relearns the compensation the next time around if it doesn't dump).

Normally only an issue with 20 quid ebay valves that don't hold a seal properly, quality kit should be no problem just giving the occasional extra pop out the back.

 

You can always add one of these................... to make sure it shuts

Just to the left of the oil filler

 

when do you need a Oil Separator?
Is it when you mod your car?

 

Pcv and breathers vent back into inlet...this air that is vented back contains oil vapour/fumes which in turn can then cause det and degrade the ron rating of fuel as it isn't a clean burn. Aos helps counter act this

so the aos is beneficial at any point imo....

It's just a catch can really that returns to sump via oil filler neck. Mine doesn't even divert into inlet anymore, I blocked inlet and then diverted pipe into a wee bottle down beside water incase of big blow by which can be caused by hard launches which can still dump oil into the inlet. So now it's only clean air ever entering the inlet.

I first used it on my hawk sti then onto the hatch both when on top mounts and now with front mount

 

What replacement shocks do people use on their hatch sti

 

 

Bilstein/eibachs from a Cosworth

 

Raggy - tell me more about your Ohlins

What sort are they, and did you choose the springs etc?

You happy with them? Did your car have OE dampers/springs before

Thanks

 

I thought you weren't going to change anything suspension wise bonesetter

Those Ohlins look good, if they are off the shelf items the springs rates are 90N/mm front and 70N/mm rear.

Not wanting to spend £2100 on them anything else

 

Anyone running fender flares how do you get wheels to fit eg with the et
Wondering to do them stuck between 50 and 110 mm ones cheers in advance

 

Has anyone painted the front grill surround?

 

I painted my new one , mesh and badge unscrew which just leaves the outter part to prime and paint.

 

Can anyone describe what it feels like ?

while I drive around in slow traffic trying to keep a steady pace in say 3rd , the car feels like I'm in 4th gear with slight juddering. If I change to 2nd I'm sitting at 3.5k rpm and ut feels to high. Say the car in front slows, I lift off and it I get a slight judder. When I go back on the accelerator (gently) it judders again.
Only feel it in 1st , 2nd and 3rd between 2k and 3k rpm.

is that the GRB STUMBLE ?

My worry is that it's the feeling it had before rebuild , and there was a load of oil in the intercooler. Haven't checked i/c yet as everything else is fine , and my mechanic said I didn't need an AOS. I still would have liked one just for peace of mind.

 

Mine stumbles generally whilst accelerating hard from lower revs, but not always. Never on deceleration. Always at around 2800. It's apparently an oscillation in the fuel, and can move up or down or get fainter after the "fix" More common with higher power. The argument rages on about it on Nasioc . Hopefully I will know more in a couple of months

 

 

hedgecutter, has your car been mapped and if so what has the mapper said about it?

 

 

martyn J mapped it; the stumble was initially like hitting a wall, very violent upon WOT, I went back to him and he said it wasn't boost cut, map was fine, but we felt a tiny misfire. He recommended hotter plugs, but no mention of the stumble. All the stumble info I have comes from Nasioc. He did say that it was hard to make the twinscroll hold boost, so I have a 3 port bcs lined up

 

Hotter plugs? Did you go from a grade 7 back to a grade 6? RCM put in standard grade 6 plugs in mine and I've just bought a set of iflr7h and was planning on gapping them to 0.6mm.

 

my bad, I mean cooler

 

I’m running 6’s at 540bhp no issues, so I doubt it’s plugs unless the gaps are wrong.

 

some stumbles have also been fixed by upgrading the fuel pump and tweaking the map to alter the switchpoints from low/medium pressure. It can be tuned out somewhat by playing with the load compensation tables on some cars too but I've not come across a single definitive fix for it.

for what it's worth my car has a stumble from 2200 to about 3400, not terribly bad but I can feel it in the lower gears when moving in slow traffic.

 

Hi guys finally got round to ordering some bc coilovers for the hatch from scooby parts ( nice price ) , now I’m looking at getting some aftermarket wheels probably some XXr 571, I think they’re called lol ,, the problem is it’s just a bit of a minefeild reguards fitment and width etc etc ,, so really looking for inspiration for fitment and sizes that work and also to see some sexy wheels 😬 , so if you could post pics and say what offset and width your running that would be great 😬

They could make a (lazy?) mapper's job shorter.

who's swapped brakes from standard discs/pads.. and kept the Black Brembo calipers?


what did you swap to?

what do they look like.. pix please?

How have you found them.. and how long are they lasting?

What did you spend???




cheers
Phil

 

 

Looks awesome Phil, love it.........
