Been posting for quite some time on this forum and decided to finally show my car. Her name is Miley and I bought her somewhere in May last year (2018) at roughly 128k km, now she's still kicking ass at ~151k.
Unfortunately, this project is almost done but I want to give a comprehensive look what I've done and my thoughts on it so it might help others.
It is a 2009 Scirocco, with not the most options in the world (pretty much none, but we fixed that to an extent) but the quad exhaust and the aftermarket silencer sold me instantly (Fox sportauspuffanlagen something, found the approval certificate for it in the car).
Now, as you might've guessed, the car's been through some hardware/software modifications, currently at roughly 250 hp and 360 nm. I will try to present the mods in chronological order and my input on it
1. Timing chain first, during hot summer and if you were to not start the car in a week for instance you could hear a pretty bad metallic sound that would go away only if you restart the engine. The mechanic confirmed the tensioner and the chain itself were on their last breath.
2. Later on I went for the S3 intercooler, which was a day and night difference, definitely recommend it for everyone even in stock form.
Fitted in NGK SIZFR6B8EG and then got my Revo Stage 1 for 95 RON gas here in Romania. Let me tell you, the difference in performance is unbelievable, 10 times more noticeable than going from stage 1 to stage 2 (which we will get to in a sec). I've always said that from my experience and trail and error, your best low-budget bet for a CAVD would be revised timing chain, revised pistons, S3 intercooler and a stage 1, you can't get any more car for this money!!!, the amount of cash you have to put in afterwards just to squeeze an extra pony from this engine might not be worth it (for some).
This stage 1 got me at roughly 210 hp and 320 nm iirc ( I don't have the dyno sheets in front of me)
3. This is where we went crazy, in a span of less than 2 months I've got the following upgrades, some of them were to prepare for stage 2, please read my bolded recommendations:
- VWR Intake - made absolutely 0 noticeable performance or sound difference from inside the car, from outside the car you could hear some woosh-ish sounds, do not recommend wasting money on it unless you really wanna go stage 2
- NGK BKR7EIX - no difference, no rough idle or such, needed for stage 2 (I was ok with NGK SIZFR6B8EG when stage 1 and stock)
- Wossner forged pistons - installed since, you know, CAVD pistons/rings are shit, my compression was perfect with stock pistons however the mechanic said my rings slowly but surely started to leak oil (I've had 500-1000ml oil consumption at 7.5k - 10k km and now is 0). For the break-in I've used Millers CRO 10w40 break-in oil and opted for a soft break-in, some agree with this strategy, some say just use regular synthetic oil and drive it like you stole, I'm not saying my method is the best, I'm saying my method is what I've done and I've had no issues regarding performance, compression or > 0ml oil consumption as of then, strongly recommend getting those if you have CAVD and planning on tunning the car, if not KS might be cheaper (like 3 times cheaper for me). I've heard some run stage 2 with KS pistons, however, for peace of mind I wouldn't.
- 03C906036M injectors - dirt cheap used from ebay, bought for peace of mind, no real world difference, people talk a lot of shit about the old revision injectors, some smart people here blame them for piston failures. Since they're cheap I recommend getting them. I've gambled getting them used from ebay, had no issues.
- Latest revision DV - for peace of mind, the old one was torn apart literally, no real-world difference, I do recommend getting this regardless considering how the old one looked
- de-cat - needed for stage 2, some recommend sports cat with this car for the turbo, the car felt slower (in between taking out the actual cat and going to revo for stage 2), do not recommend unless you really wanna do stage 2
- NGK U5002 48003 coil packs a kind forum user here recommended me these and this article: http://www.gt-innovation.de/wordpress/t ... tage1-2-3/" onclick="window.open(this.href);return false; . They say
Definitely recommend unless you want to go for R8 packs which might or might not be necessarilyThose NGK coil packs with the code : 48003-u5002 are used on 1000hp builds in rb26 Engines and not only, so be sure that they can definitely fit the needs of a 1.4 tsi engine with 300hp or 400hp, so don`t through your money away for nothing.
- De-ResL Sounds a little bit with more bass, a little bit more volume, gf didn't notice any difference in sound, I heard it does nice farts with the DSG however. For the price of getting it off, I'd say why not
4. After the break-in was done, literally the following day I went to revo for their 100 RON stage 2, again, I don't have the dyno sheet in front of me but it made somewhere in the neighborhood of 240 hp and 350 nm, the difference was not mind-blowing, the dyno clearly showed that until 3500 rpm the hp/torque was literally the same, I almost dare to say that it almost didn't feel any improvement in real/relaxed driving, probably the tune itself didn't make that much power on its own but the other upgrades slowly added power when I was stage 1. For the money you have to spend on the intercooler, intake, exhaust (in my country not really, but for some going de-cat would be troublesome) and whatnot, I don't believe it's worth it unless you want to squeeze the last hp you can on stock turbo..
5. Custom De-Cat De-Res 3" downpipe + 3" turbo back exhaust (basically I only have the Fox silencer in there). I can't tell you enough how much power and torque this adds low-end, I dare to say it added 10 horses easily. I also dare to say it made more difference than going from stage 1 to stage 2.
That was it with the performance upgrades, pretty happy with the results. I've recorder a 0-100 km/h of 6.4 seconds. Mind you it was done using a phone stopwatch and until I had ~102-103km/h on the speedo. The first gear was slipping all throughout until 2nd gear so a better driver than me could time less I suppose
. Never tested top speed.Now, remember when I said the car came with pretty much no options? The interior originally looked like this
Now it looks like
I've upgraded
- Retrofitted cruise control (HUGE improvement even tho I don't do highways often)
- RCD330g plus with android auto and bluetooth, no more phone into the AC vents
- the speedo to one from a Golf mk6 GTI, looks business, shows oil temperature which I really like
- Steering wheel to a Golf mk7 R Line, absolutely love it, buttons are not working atm, I've read on retrofit forums that even with a highline steering wheel column model you still need to do some custom adaptations, my previous cars all had steering wheel buttons and didn't use them much so I'm not sure if I will continue investing into this.
- Plast dipped the plastic trims to matte black, it makes a nice and subtle difference imo
Future plans:
Not much tbh, I got more hp than I ever hope to from this little engine, oil consumption after 5k km is 0. The plan was always as much power as I can with daily-driver reliability which I believe I've achieved.
Not looking forward to throw in some forged rods thus not planning to go for a hybrid turbo or whatever.
- Take out the "Scirocco" and "TSI"badge from the rear and the VW Logo from the front of the car
- Going to get my plastic trims to a professional and have them painted to something resembling piano black, the plasti dip looks rather cheap.
- Switch my bulbs to something like osram for a white(r) light
- Still debating whether to get lowering springs or not, we don't have the best roads
Current problems:
Couple months ago my car refused to go to reverse and sometimes first 2 gears, bought a new gearbox from a wrecked 2010 CAVD scirocco and now I started getting the reverse issue again
Bonus, 2 or 3 times it refused to go from 4th to 5th/6th We'll see what's up with that.Aaaaaaaaaaaaaaaand more pics
