what can a stock turbo jetta handle?

[wolfjetta]

does anyone know what a stock turbo jetta can handle boost wise? and not blow up

[OutKasted1]

Tranny, tends to be the weak point. Just go with a GIAC X+ chip and some bolt ons and you will be in good numbers. other than that you can upgrade to k04 turbos, or an APR stage 3 setup, but you are looking at some $$$. I know there has been GTI 1.8ts getting into the high 13s on stock intenrals. But again, anything is possible with enough money.

stock internals on the 1.8t can take a LOT of power... there's a few cars on this forum running 300+ wheel hp with a big turbo and upgraded clutch...

if you've got tiptronic on the other hand... its another story as to what will break first...

[Komrade]

from my awesome vortex experience, stock internals for a 1.8t will hold up to 400ish HP.

your stock turbo depends on what engine code you have (AWW,AWD,AWP), but all in all, you arent gonna get much more than 250 hp and 280 trq out of it without modifying it to the point where you might as well upgrade to a larger turbo.

with all the bolt ons, you can expect close to those numbers at the wheels as well as a 13 second pass in the quarter, depending on how well you can drive.

good luck!

A lot for a stock engine.
Like Factorx said, many 1.8t owners on here are pushing some serious power down, without any serious engine modifications.


We could be more specific if you listed what you want to do, what your plans are, what HP/Torque your aiming for...etc..

What WOULD break first? Only thing I see as a downfall in my car is the tt =[. When it goes bad, I'm probaly going to do a manual swap.

[FactorX]

the tippy is not going to handle that kind of power... one of the guys down here in SRQ figured that out and is trying to decide on what to do...

a manual conversion is NOT a fun project to be undertaken lightly... its a SERIOUS job...

[Garlic]

Yeah, very true. If I do end up doing it, I do plan on taking my time and not rushing. As I rather bum a ride for a few days than to be out of a car for much longer.

[im_a_local]

lol a few days? you'd prob need vag com, just to be safe. plan on swapping harnesses, ecus, the pedal cluster, plus more. plan on running into some headaches. And don't be afraid to ask for help, I'm sure a bunch of other people wouldn't mind helping.

As for a k03 equipped 1.8T, even after you reflash it, and add exhaust, you'll end up replacing the turbocharger somewhat soon thereafter. I have read offical audi documents stating that turbocharger will turn in excess of 180,000 rpm. At that speed, seals and bearings breakdown, and you'll start to hear a winding noise, which would be your compressor wheel machining the housing. I've seen it on unmolested cars also (used to work @ an audi stealership). Jump to a K04 and the shaft speed stays at about 140,000, which is somewhat more reliable.

In either case, you'll see about 240-250 crank hp with the K03, and maybe 265 w/K04, IIRC....

as for stock block? well, Billy T is the man on that. shcrick cams and a 5 angle valve job, completely stock long block otherwise- 490 whp. Yeah thats right........:bow:

[kelso]

i thikn id rather just buy a manual and sell the tippy than do a manual swap on it, personally

no way. a 1.8t will not hold 400hp on stock internals... and its not really the hp we are worried about. its the torque numbers. and since 1.8ts seem to produce either the same tq on big turbo applications or more tq on stock turbo, there is no way that stock internals will hold 400 wheel tq

like said above. if you are looking for power. basic 1.8t bolts on and a decent driver will get you into the high 13's

intercooler, turboback, ecu tune(giac, apr,revo, blah blah), intake, turbo inlet, throttle body/intake manifold samco hose. and water meth wouldnt hurt.

will some traction that will get you into the high 13's

not worth all the work in my opinion!

[Komrade]

ive personally seen 1.8t's with high 300 HP at the CRANK, so around 300 at the wheels. i never meant to imply that stock internals could hold 400 at the wheels.

[rafiki]

oh i agree. i have seen handfuls and handfuls of 1.8ts holding 300 wheel hp and 300 wheel tq

the line for stock internals on a 1.8 is 350 wheel tq

[Komrade]

i concur. have you dyno'ed your car yet? i havent really payed too much attention to the mk5s power?

[rafiki]

i have no dynod my car yet.
but there have been a number of mk5's that have dyno'd in the area and online

there are cars that have reached the 300 lb/ft tq mark with only an intake, turboback, and chip.

there are a few different cars here in town that have dyno'd 265 wheel tq. and 220ish wheel hp, just chipped!

here is a good example

http://forums.vwvortex.com/zerothread?id=2834618


i have done a number of pulls with a number of mk4 guys. i have pulled or pulled right with. guys that have 3 grand of motor work done.
a number or 1.8's with intake, turbo inlet, chip, dv, turboback, front mount, trottle body/intake manifold/ samco hoses everywhere...

a guy at fixx fest a few months back with an intake, exhaust, chip ran a 13.8. impressive.

but these cars are not meant to be super fast. no vw's are

[Komrade]

yea no kidding about the super fast comment, but for the size/fun i cant be too upset. im a bmw guy, so the vw will soon be the daily for bigger and better projects to come.

[rafiki]

true, i hear ya. bmw's have a special place in my heart. but for now im a huge vw fan. i would love to have a 1.8 to put into a mk2 or mk3 just to track and have fun with.

[Komrade]

yes sir. e30 for m3.......soon. currently employed at a bmw dealership has also converted me to the darkside of 6cyl rwd forever.

[rafiki]

true. i want an e30. i dont even care if its an M. i just want to dump one to the floor and put some bbs rs's on it and hope to god it gets like -4 degrees of camber and just stare at it

[Komrade]

yea i personally know 4 techs that have 335i's now, and i'm just waiting for the new m3 to come out so i can get a nice chunk off the previous gen(e46). that, with smg and some 19" LM's, maybe some FI for the engine and im done.

[Garlic]

I love the 30's. To me they have a special styling to them.

[boostit6spd]

stock mk4 jettas can handle a very good load i would say. i had an 04 gli that was pushed to the max and ran great through all the boltons and then through the big turbo and methanol kit. we made around 300 whp on the mustang dyno at central florida turbo on a boost setting of only like 18 lbs and 0 degree of positive timing on the motor. i drove around town with it at around 22 pr 23 lbs of boost and 8 degrees positive timing when i wasnt there and the car block held together fine, it was actually still quite a nice daily driver. the only problem i had was building out the tranny after it blewout somehow about 40000 miles on the car...... whether or not the power led to the tranny remains unknown.

forgot to add:::(With the stock auto tranny however, power becomes to much at about a k04 power level before you need to "repair")

[rafiki]

of course it had something to do with the power sammy!
and that you beat the piss out of it :)

i sold my jetta with almost 50k on the clock and the tranny was as smooth as it was when it had 5 k on it :)
