Tuning/ sound questions

[simyboye]

Hi,
Without wishing to sound too stupid, I'm nearly finished with my 90Q Aby conversion...
However I want it to sound more growly.

Got a spink ecu re-map. But the engine all sounds too dignified. Not feeling that.

Whats the first few mods I can do?

Got an oldskool DTM back box coming. Should I delete the centre box?
Air filter? Whats the best route to go? Cone filter etc?

Many thanks

*******ised airbox like I have and a single box, 3" system, that'll sort it but with none of the hissing and farting of an open cone and with all the OE heat chielding in place too

Was told by the guy's at AAS up here that putting a 3" system on ( which they have tried ) fouls going over the back axle so they did a 2.5" ( or was it 2.75".. ) on mine, anyway the same size as the stock 3B downpipe, and it sounds lurverly....

It has 2 boxes so is nice to tootle in but when opened up....

PS Rusty what did you actually do to the airbox?

HTH

3 inch is possible if taken to a decent place, I think james would like an open cone filter andy, just need to make sure its well protected against heat from the engine.

If wanting to go the airbox route you open out the front of the airbox BELOW the filter line so its a gaping front to get some decent air in, I did it on my old one.

James - also have a word with tonk's about the system he used to delete the recirc valve that gives a more s1 sound to the car but its not cheap iirc.

Easy to delete it, just a couiple bungs
Best way though it just get a good quality adjustable blow off valve, HKS SSQV is a good one - you can wind it up so it doesn't open until say 8 psi, then you get that lovely chatter of the impellor stall at low-ish boost and still get the valve relief on high, more potentially damaging boost levels

I love the sound of that chattering. is that with the re circ deleted? can't stand that rs turbo type dump valve.
I might go with a cone filter...

will need your help soon Pete as my car is a little rough on idle. smells a bit lean.

thanks guys.
