some questions about my gti

[Cakija_GTi]

i was wonderin how safe is it to boost up my gti, for mods i got a front mount, blow off, intake, and a i belive its a full exhaust that my bro put on, i wanna get a boost controller for it and go a few pounds up, not sure whats the safest with that?

also i heard that on the gti to get the most power u gotta chip it, whats a decent chip, how do i install one and what exacly do they do n where do i get them?

thanks in advance

GIAC engine ECU flash is your friend. It's all done via the OBDII port. Takes about 45 mintues total time. 40 to 60 HP increase for under $575. :drive:

damn im still gonna have to save up a bit for that one ive got other stuffi have to take care of, but do you know anything about boostin up on a stock turbo

That's what a chip does - it increases the boost, among other things.

Okay seriously...I've told you this before when it comes down to modding a 1.8T, it's very basic.

1. Ditch the blowoff valve
2. DITCH THE ****ING BLOWOFF VALVE
3.DITCH THE GOD DAMN BLOWOFF VALVE

Now that we're past that we can get to the real mods
4. Boost controller isn't necessary on a 1.8t, PM vwmeister and ask about a GIAC performance chip, best 500 bucks you'll spend on your car, worth every penny and then some, honestly he should be charging about 2k for every chip IMHO, they're that good.
5. Once you ditch the BOV a Diverter Valve should replace it, search vwvortex for a used Forge 007 if you're on a budget, take it apart, clean it, and put it on. If you run more boost on your car you're only going to be running that much more rich if you keep the BOV.
6. If you run an entire turboback exhaust, about 2.5" or more should be fine, then you don't have to buy an aftermarket downpipe.
7. If you don't take that BOV off I'm going to find you and do it for you while you're asleep, and then you'll wonder why your car will be in limp mode.

A GIAC chip (Kevin correct me if I'm wrong) along with a FMIC if it's any good should hold at about 16 PSI, on a stock turbo. BUY THE CHIP, honestly it's better than spending 200 on pulley's 250 on an intake, and 500 on an exhaust, and 250 on a high flow induction pipe, as well as a front mount intercooler (FMIC) for 300. WAY better. Honestly running a FMIC isn't even necessary on stock turbo in most cases.

looks like thats what ill do, ill be savin up for a diverter valve, switchin it with the bov ASAP, n den ill be savin up for that chip :) out of curiousity with a 3" turbo back... and that chip how much hp u think il be runnin?

Not sure ask Kevin, but friend of mine (031.8TTT) has APR (similar but not as aggressive so I've heard) and it pulls in 5th gear even pretty damn well. He alreadt said about 45hp 60tq increase or something, and a full turboback probably adds around 10-20 I really don't know.

yeah thats not so bad i just found a dv for 85$ on vw vortex, im gonna get some money together and get one, the dv doesnt make the same sound as a bov does it? lol kinda love that sound but hey if its better for my car screw the sound

While a BOV sounds nice, and some people (specifically people that own them, wonder why that is :rolleyes: ) will say it's okay to run on a 1.8T, it is at it's very simplest, a bug in an otherwise perfectly operational system, that has the potential to ruin your entire fuel map. With an intake and a DV you can hear the DV "breathe" back into intake. Sounds pretty good but it's not as loud as a BOV. Buy the DV, your VW will like you a lot more for it.

what ever is best for the car... but one more question i was told i would need a bigger fuel pump? and with that chip could i still get a boost controller and boost it up a lil bit or?

No, you're fine with the stock setup on the stock fuel pump regardless of how much boost you're running on it, because you probably won't make it past 22/23 PSI. Don't waste money on a boost controller, the chip will take care of all of it for you.

yeah i didnt want to go over 18 psi or so on my car i just want it to be fast... but gotta save up money n do it the right way

Hopefully my friend with the chip runs his car at Cordova, I'll post his 1/4 mile time.

I agree with almost everything. Except #4. Boost controllers are very good at keeping you from overboosting (surging). I run one and boost comes on smooth and strong and holds at 18 psi all day long. While not everyone experiences surging, BC are the cure if you do once chipped.

And also, there is a diode mod. Look it up on the vortex. It will allow you to see higher boost levels. It's ghetto so that's all I know about, so it might fit well with the rest of your car.

[Kelso]

My jetta has a chip (giac), CAI, 007 DV, N75J, boost hoses, turbo inlet pipe, and APR turbo back, amongst others, but I top at 23-24 psi and level out at about 19. No upgraded intercooler...yet. Hope that gives you and idea of what you are or may be looking for. Gary did a vag-com dyno on me and posted it.

hahahahahahahaah!! That's what I was thinking, but seriously, from someone who has modded a 1.8T to death, ditch the BOV. I ran an EVOMS CAI and BPV and had a nice sound. But, if all you are worried about is sound, I get a bad inclination that you aren't into real modding. Modding a 1.8t is simple and straight forward.

Chip
BPV
Exhaust
clutch
flywheel

I honestly think most front mounts are a waste and most aren't as efficient as the stock SMIC. You can get a SMIC upgrade that will be more efficient. I ran APR chip, 3" GHL exhaust, sachs vr6 clutch, 14lb flywheel, EVOMS CAI and BPV and it was very reliable boosting to 19psi holding at 16psi all day long. Like Kev said, a BC will help with surging and over boosting in CONJUNCTION with a chip. Don't just diode mod and use a BC. A chip is professionally tuned to compensate fuel and timing.

[Kelso]

According to the vag com im near 187hp to the wheels and 250ft-lb tq

[l1t43]

you know a bov is almost exactly the same as a dv, it just vents into the atmosphere. I don't encourage doing that, but I have a bov and I just route it back into the intake. Its fine that way. There really is no sense in buying a dv if you can make your bov work the same way. save yourself some $$, buy a hose instead.

The only thing the two have in common is they are for preventing compressor surge, otherwise they are completely different, one shoots all the excess air int wherever, and the diverter valve sends it back into the intake, putting a hose from a BOV to the intake is stupid, ghetto rigged, and probably impossible for this kid to do himself.

Agreed, spend the extra money and do it right.

[l1t43]

I'm sure he could figure it out. Putting a hose on isn't that bad. The only thing i'm thinking of is how his bov is installed. If its got a flange welded where the dv hose should attach, there'll be some problems, and he'll have to get a new pipe. Either way, it'll be ghetto rigged if that's the case. Cakija, how is your bov attached?

Trust me, he's not knowledgeable enough to reroute the air back into his inlet pipe...

smart man, im runnin APR 91 (becuz kevin was gonna b outta town the only weekend i had time to get my chip:( otherwise i woulda went GIAC but im happy with my APR) forge 007 and the sachs vr6s w/ the 14 lb flywheel with exhaust is the smart way to go, along with possible other mods AFTER you get those done if you have the money.

[Cakija_GTi]

Cakija, how is your bov attached?

no clue dude all i know is that its like behind the engine where the stock one was at, my brother installed the hks while i was sleeping i didnt even know about any of it till i woke up

Just saying. :tu:

I was simply reinforcing Chad's statement, and 4 different people in this thread have told him the exact same thing and he still asks if he should do it or not.

you were a pretty big ass clown to him tho firz. just sayin, still <3

The stock one is actually on the intake pipe, and has a hose running to where your bov is now. If its behind the engine bay, unless he really half assed it, it's got a flange welded to that pipe, and the bov attached to that flange using bolts. If he did half ass it (pretty good chance he did, as he did it while you were sleeping...), then it's just being held on with a small hose. You should post a close up picture so we can help you out better. If it's welded, it'll be a big hassle to get a DV, and you might wanna go another route and make this work. If it's not, you should buy a forge or something like that.

its not welden on, i can get some pics maybe in a pic or so when i get the car back from the shop still waiting to get my clutch..

[vrjetta98]

tell your brother to go drink some gasoline and lay down in a house fire.... this is not at all contributing to this but serioulsy if someone did that to my car (sonething while i was sleeping) they would have one less testicle then they use to when they woke up

[l1t43]

I think the car used to be his brothers. Right? I assumed he did it while he owned it himself. I'd hope so at least.
