Yesterday I removed my vaccum pump and I installed a vaccum pump delete kit, the brake booster is now connected to the manifold intake. I do notice a little difference in the brake assist I would say it's better. It's not a performance upgrade, I just wanted to get rid of my vacuum pump before it starts to leak. Installation is pretty easy, it's a bit long, I did a mistake by removing the vacuum cover, oil leaked over tools and it was a bit harder to manipulate, except that, the installation went fine.
I also noticed that the car is a bit more quiet on iddle, I don't know why, but the first time I started the car after the installation, a EPC light went on the dash and then disapeared a few seconds after. My friend also told me that the smoke from the exhaust was a bit more black than before, I don't know why too...
Anyway, here are a few pictures:
I bought Audi coil packs and NGK iridium spark, I will install it next week when I receive the package.
The next things I'm planning to buy it's the transmission and engine mounts pair sold by 034Motorsport.
I haven't been that much active on this topic before, so I'm just going to enumerate what I have done in the past months, changed the downpipe for a USP high-flow catalytic, changed cat-back for a TechtonicTuning exhaust with dual Borla tip (Sounds awesome, I will post some videos this week), tuned the car with UnitedMotorsport Stage 2, since the car is tuned it's make back-fire sound as hell each time I release the gas pedal, I'm not sure if it's normal. When I think about it, even if the manifold valve close, there is still a few O2 in the manifold and I don't think the gas is too rich since the car is tuned for 91 / 93 and I'm putting 91, so it's maybe a sparks that is not fully wokring as it should, well I will be able to confirm this soon, I'm replacing coil packs and sparks next week. It didn't make pop sound before the tune and before the tune, new downpipe and cat-back was already installed.
Edit: Finally I bought 034Motorsport engine-trans pair mounts today, I will install it next week too, is it hard to install ?
