Hi all!
I've Just signed up on here, I bought a stunning Vectra B 2.2 SRI 150 estate in super rare Persia red with low mileage of 69,000 last September, and now xmas and new year are out of the way I want to make a start on tuning the sound lump, its is smooth, quiet and strong but would like her to go as well as she looks.
here's a pic...
Now before xmas I got the management light up so I plugged her in and she was complaining that the cat was under-achieving so unable to find any info on a sports cat wanted the best quality OE unit I could get as I plan on keeping the car so didn't want some cheap Chinese tat and be back replacing it 18 months later, a quick call to my girlfriends dads place and insistent on a Walker unit, he said that they aren't serviced in the UK he called back half hour later and said Ive got you one coming in from Hungary, glad I insisted because the quality is amazing! Today I've just ordered the Remus center section from LMF which between the Walker downpipe and Irmscher backbox will make a tasty system which now brings me onto here, got a few ideas for engine mods but seek your wisdom, one thing is sure I WANT IT SUPERCHARGING!
The ideas are as follows...
*Exhaust system as mentioned Walker downpipe, Remus straight through centre and Irmscher backbox
*3 pipe mod (don't know exactly what this is someone please explain)
*Blank off EGR (do I need op-com to delete it)
*GM Supercharger kit (need input on throttle body, heard about fitting 2.4 unit or bore out standard?)
What power gains can I expect from those mod? please advise on proposed mods and or any extra things to do.
Thanks all!
