OFFICIAL****2.0 8v turbo spec lists thread(whp,psi,etc)

[Mark Morris]

pulled 260 hp and 272 tq, fuel trims were a little low at full boost they sat at 11 to 1 at full boost i would like to see them around 12-12.5.
a
lso wondering if stock bottom end and stacked head gaskets will handle 23-25 psi just at the strip to get me over 300 whp.

12.5:1 is too lean, especially with pump gas. I wouldn't push the a/f over 11.8:1.

Right around 300 wtq is when the stock pistons tend to start going south-- avoid big torque spikes down low and you will have better luck keeping everything together. Be conservative with your timing and run some good fuel at the track.

This thread is all too inspirational... Leaves me with a few ?'s.
Whats the estimated cost; on the most basic, but reliable turbo setup?(cheapest lol)
Est results too?

[rabbitchaser]

race fuel will be in the tank for the track most likely,

"Cheap" is not a word most of these guys worry with. If you are planning to run a "cheap" kit, then go with a bolt-on kit from Ebay. Keep the boost low and don't ask for a whole lot more than what you get after install and software. The 2.0L is a solid motor and can be pushed a LONG ways! But you have to spend money on the correct hardware and software to get to the level most of these cars are.

You can buy a decent base kit for $600ish and bolt that on, get software from C2 or whoever for $300 or so and just roll with that. You'll be seeing probably 150-170hp and have a pretty decent little car. But there is a LOT more to get out of this engine, but you have to invest the time and money in a solid build to get it reliably.
-J. Hines

I'm sure some of these guys can make first-hand impressions from their kits. I'm just finishing my N/A build on my ABA and won't be turboing it until I swap it from my GTI to my Caddy.

[dubvinci]

i keep seeing people talk about afr's and saying the lower numbers are too lean...ive always thought that higher numbers are lean...to me 12.5 sounds rich...with 14.7 being stoich...

When speaking of forced induction, 12.5 is too lean, when speaking in n/a terms, 12.5 is rich.

Went from this


To this

Supertech valve springs (ti), 276 cam, and copper headspacer. Needs a new dyno now.


Put it all back together and now I have bad piston rings. [Banghead]

[rabbitchaser]

i think im going to be picking up the 276 cam and tt springs here soon. j


then it will be lugtronics, and hoping next year to be tubliar exhaust mani, diffrent turbo and ie rods and je pistons. im going to try and get my gti into the high 9s low 10s.

also i drove the gti all this week to and from my new job, a little over 250 miles and filled it up today with 8.5gallons of gas which equals out to just under 30mpg.

-OBD1 bottom end
-RV hydro head
-homemade turbo manifold
-Corrado intake manifold (had the ISV port I needed)
-homemade 16v-to-OBD1 TB adapter
-358cc injectors (some sort of Saab IIRC)
-14b DSM turbo (clocked, w/aftermarket Garrett internal gate)
-4 speed 020 (long ratio)
-OBD1 engine management, tuned by me (see sig )
-stock MAF
-Stock "T2" intercooler from a 90s Turbo Dodge
-2.5" downpipe, open wastegate dump, 2.25" exhaust for now.

No idea what power it makes, I have no dyno time booked for a while .


The IC piping looks odd because it's a hodge-podge of stuff I found at the scrappers.

[papo98jetta]

Those are nice numbers.

At what rpm?
Also torque and @ what rpm?

Great numbers!

this thread makes me want to finish mine now

[Mr. EüroMatt]

Been lurking this thread for a while. And now it has me ditching my supercharge plans for my 2.0L.

I have a 2000 AEG 2.0L with the following:
- ABD CAI w/ K&N cone
- Tectonic Tuning 260/268 sport cam shaft
- Sachs VR6 Clutch
- 22lb flywheel
- Unitronic Stage 1+ software

I'm not looking to make BIG power, but something in the 170-190 WHP range would be great.

Last time I dyno'd I had a bad cat that needed to be replaced and put down 108HP/118TQ.

I saw the top-mount inner-coolers in the pics and has me intrigued. My main question is about heat-wash.

Any suggestions about what I should look at doing to get those numbers?

Motor is sitting with 155K+ on the clock.

Trying to tuck in the bay a bit more than before.


Custom LRI, all the piping and intercooler done by me.







Just waiting on a few pieces of stainless to finish up the dv piping and lower pipe.

No more tiny IC in the front like this picture.




Ill get some nice pictures of the bay when I finish it.

[Rocambolesque]

I can finally post in this thread.

2.5" mild steel DP
2.25" Eurosport exhaust
Short ratio AWY 020 transmission




Running only 5 psi right now (MBC bypassed, running on wastegate actuator only) as I'm having problems with the MBC. Full boost by 2800-3000 RPM. No idea what kind of power it makes, but its lots of fun
Next season plans: Clutch, diff bolt kit, 10 psi and a trip to the dyno.

[groundupjetta]

Everything looks great ^^^ the swap, the turbo setup and the car

Nice numbers Filthydubber and also a nice powerband , that thing must be a pleasure to drive. When do you see full boost?

[Filthydubber]

Full boost (19psi) before installing my LRI was about 35-3600 and now is about 3300.

[95jetta17]

anybody on here get real bad boost spikes with there mbc? im using a kinetic mbc

[dubvinci]

just bumped mine to 15lbs...crazy the amount over stock it is...now someone needs to buy it...see my sig...

[vacuumnoise]

do you have any video pulls?

[Filthydubber]

Im running the Halman MBC with the ceramic ball and heavy spring and do not have boost spike problems.

[dubvinci]

do you have any video pulls?

heres a short one from this am...3rd gear rolling on the throttle from 50-80...just got to WOT when i had to let off...sorry for the unsteady camera...was goin around a slight curve and catching traffic faster that expected...lol...need to do one on the highway and not a curvy backroad...

[groundupjetta]

^^^^ Like the vid, can you give us more info on your setup? what turbo, cam and management

[dubvinci]

ebay t3/t4 ar .63 intake and .48 exhaust i think, 42 lb injectors, 3" maf, ebay bar and plate intercooler 2.5"x7", c2 shipped ecm from their stage 3 kit, custom 2.5" exhaust, no cat, single chamber flowmaster and side exit, stock AZG with around 160k on it. home depot MBC, stock 1.8t recirc valve. thats about all i can think of...i will try a better vid here soon...i didnt think to do it til i was almost home and was on a 45 mph back road with some bumps and curves...lol...its really fun on the highway especially with the 2.0 gearing. dont even downshift...lol...

[Quintin@USRT]

good strong power band one thing i LOVED about my big16G. that'll do a good 325whp if u up the boost. Ever thought of water/meth?

Yes I have Quintin, but I'm only going to do it if I get it properly tuned for it. IE going to standalone, which would mean I would have to go to a 1995 or older chassis to pass CT emissions.....

So for now Im just going to have Jeff Atwood write me a 630cc 4bar file and run more fuel until I swap chassis.

[vacuumnoise]

this is prolly a dumb question, but if i do water/meth setup I don't need an intercooler right? I plan on boosting 12psi or so...

& to all the Turbo 8v setups

if you're gonna have Jeff WRITE you a 630cc file then have him add a few degrees of timing to it as well. Jeff doesnt just say "oh here's a generic file"...

[jettred3]

[vacuumnoise]

O YES

[Filthydubber]

Well technically he will be using my car to make his me5 2.0t 630 software, so it will probably be a generic type file. After he writes that, maybe he will throw in a water meth tune for me.

thats good cuz i'm gonna put together a quick 8v when i get back to germany so i can slaughter the autobahn
