---Before I say anything I want everybody to know that this isnt a rant to any specific members on this forum or anywhere else. I know a lot of people on this forum will read what I say and go, well almost everybody already knows this stuff. Problem is people pretend to much so its not true. With that said I hope this helps anybody down the road who do eventually get this car because its beautiful and it deserves proper care.


Ok well Ive been doing a lot of reading, the hype over the past month for this car has jumped up considerably. (wow I cant spell)
Anyways, a lot of questions are being asked about the whole BOV and tuning situations. A lot of people on you tube and a lot of other forums are talking about immediatly swapping out intercoolers and doing other ****.

Guys this isnt Gran Turismo, its not that easy.

First, unlike bolt on turbo kits that almost every e-learner is familiar with... This turbo, the engine (including the tranny), is plugged into the computer. The car monitors everything. You change anything (other then basics like intake/exhaust), your gonna throw a code. The car will go into limp mode (which I'll explain later) so you will not damage the car.
In order to mod this car beyond basics, proper tuning will be needed.

Now lets talk about this "proper tuning".
First, the future looks extremely cloudy about GM stage Kits for this car...
Reason being- theres no more pulleys or BS...
Second- Tuning, remapping, or mostly known as "chipping" will not qualify a reason to get a BOV. "why is that? I know plenty of people running small boost and chipped and have a BOV on there VW" BECAUSE THIS CAR IS NOT A P.O.S. VW!!!
There software is completly different. Your software, turbo, engine, and tranny are all Sweden based... Not german, Now what company does GM own that hails from Sweden??
SAAB. Almost everything is Saab based... this engine that was first introduced on the solstice gxp, is the same 2.0T in a Saab 9-3 just re-tuned and different tiny parts (like the intake)...
So if you do 2+2, this engine actually came out in 03 when the new Saab 9-3 Arc/Vector came out.
Third Chipping and remapping will make your car perfect for downpipes, getting rid of the boost nanny, maybe uping the p.s.i. a bit, and intercoolers... Just choose the right software (Stage 1 is usually just the tune itself, Stage 2 is I/D/E + tune, Stage 3 is usually boost tuning + I/D/E + intercooler)


If you plan on upgrading the turbo further down the road and doing the entire swap, you'll need a stand alone ecu for it, and even then it will still be hard to trick the cars computer thinking its still the stock turbo... in which then, you may get a BOV.

Simple as pie, piece of cake...

Back to limp mode
Limp mode means you'll prob be limited to 3k (meaning thats your new redline) and your boost will prob be completely cut off... Resulting in very little power and a dealer trip to erase the code (maybe fix something if something needs fixing) and a recording in there system that you just fucked with the car voiding the powetrain warrenty. If you just did intake and exhaust, they'll have to prove that those mods were the cause, but re-tuning the ecu and mods beyond that will void your warrenty... almost no way around it.



I didnt cover everything I wanted to because its late, but please feel free to ask any questions if you have them, like I said in other posts Ive been dealing with this engine for just about 5 years...
Mods and supervisors if you feel ranting was going on feel free to edit anything I said or if you feel I was very helpful to anybody feel free to sticky...

Happy tuning fella's and I hope everybody trying to get the boosted SS has success...

 

I also dont get the BOV talk.

Why would u want one? With the No-lift shift, you wont lose boost when you shift so the BOV wont even go off. So the only way to make it make noise would be to not use the no-lift shift function.

Correct me if im wrong i guess.

 

i currently own a vw gti 337 turbo. they come with diverter valves just like the cobalt. as soon as you get a intake on the cobalt you should be able to hear the whoosh noise since it dumps it into the intake track. i actually like my sound more than some evo's or sti's.

when i first got this car i found myself flooring it for 4 seconds just so i could let off the gas so the person in the lane next to me with their window down would relize im a bad ****.

ps.. i dont understand youre vw comment
pss.. im trading it for a ss

 

because ricers jack off to this noise pshspshshspspshshsspshspshpshsps

 

Most people dont understand the no lift shift
If you've ever heard the demo video of no lift shift... it sounds like you are lifting but thats when the cars comp takes care of everything with the throttle.... they dont understand boost is staying up.

The comment said about the intake increasing our diverter valve sound is entirely true... Its a million times louder when releasing the gas from under load, you'll love the sound especially near buildings with stone walls

My VW comment was said because almost every person that owns a VW around me has a chipped and BOV 1.8T gti

 

I completely agree with this write up. Most of the people talking about all this stuff are kids and don't realize that all this stuff could have easily been done YEARS ago, but now cars all all electronically monitored and everything becomes a crap-shoot.

 

Its like i said before, "In the quest for power, warranties will be voided". If you look at most of the addons for performance (tuning chips), they usually say put back to stock before taking in for service. Car companies have gotten smarter now. Computers in cars now dont really take addons well. I am getting an ss/tc though. Im not gonna do anything to it. Im just replacing my true love. May she rest in pieces.

 

Besides I think I can wait till 5 years is up anyways...
Basics like intake exhuast Ill def. be doing pretty quickly
Other then that its gonna be all audio/visual mods like kicker L5 sub, HID's, maybe a CF hood I dont know, depends if there is a signifant weight drop because I want a CF hood that actually will be beneficial, im not a ricer...

Anybody have any plans for when they buy it?

 

i plan on replacing the trims inside with the red replacements you can buy to match the whole interior

black and red= sexy on the eyes

 

I wouldn't say the 2.0t saab engine is the same as the 2.0t in the ss/tc....The ss/tc is going to have (i'm assuming) beefed up internals, plus it will be running direct injection and vvt which I don't think the 2.0 saabs have.

 

I/E and audio, Alpine IVA-W205 double din 6.5" touchscreen head unit, SPX-17PRO 6 1/2" components, with SPR-69C 6x9" seakers in the back, with the 12" type x sub with all that ran by a 4 channel x 150w for the speakers and a monoblock 1000w for the sub, keeping it all alpine, been researching lately and I'm impressed with them, looked into pioneer, kicker, and some others and just wasn't that impressed.

 

After I put about 1,000 miles or so on it I plan on doing I/E. I was thinking about doing a turbo timer, but I heard you don't need one with stock turbos. So idk.

 

Yes it will...

Sadly.. no...

 

I thought the lnf had stronger pistons than the lsj.

 

yeah they have forged pistons

 

yes I do have direct injection and variable valve timing in my saab, your thinking pre-2003 crap 2.0t engines
There's a reason why the 2.0t has changed to 2.0T (look at the T's if people still dont understand lol)
As I said before its the same engine with tiny differences in parts and tuning...
Aka saabs dont have forged pistons

Dont need one...

 

i rode in a saab 9-3 that an enterprise guy picked me up in

that thing was ***** out fast

they were gonna let me take it, but im not 25

 

Replacing the recirculating valve on a 1.8T results in lost power...

And 1.8T's are not pieces of ****, despite your random call-out.

 

You obviously have never seen VW ratings then my friend... There rated the worst reliablilty and maintanence costs out right now. But whatever floats your boat... there nice looking cars and if tuned right there pretty quick but ill never buy one

 

Yeah, obviously.

If I had a quarter for every time my 1.8T broke down... I'd have a lot more saving to do.

 

All the current Ecotec-based Saab 2.0L's have direct ignition used with their Saab-specific Trionic 8 engine management but they do not have variable valve timing nor direct injection (i.e. injecting fuels directing into the combustion chamber using extremely high fuel pressures vice injecting at the cylinder head inlet port via the manifold, which is multi-point/port injection).

The difference between the low-pressure "little t" and high-pressure "big T" Ecotec-based engines was primarily the turbocharger and the engine calibration. The low-pressure 175hp cars used a smaller Garrett turbo and the 210hp high-pressure cars used a bigger MHI turbo. The low-pressure engine is also still available outside North American markets but because of trim changes and with the introduction of the 2.8L turbo V6 a couple years ago Saab USA axed it from the lineup to simplify and better compete in our market (you can also get a non-turbo 1.8L and a 150hp 1.8L turbo overseas in addition to the diesels and the BioPower (ethanol/E85) Ecotec's we don't get.)

Saab is the engineering expert for turbocharged powertrains at GM and you can bet they did most of the development for the new direct-injection/LNF turbo Ecotec. They currently don't use that engine in the 9-3 (and the 9-5 still uses the Saab-developed 2.3L B235R Ecopower engine), but more than likely they'll be using it in their new upcoming cars that are going to hit the market over the next couple years.

 

It's going to be a lot easier than you think.....

Westers has 'cracked' the ECM, so all is well with modding.......

http://www.solsticeforum.com/forum/f...xp-tune-43585/

 

To the OP: Have you talked to an engineer from GM that helped develop the car?? I have. He was at our meet yesterday and did a huge presentation on the ss/tc. There will be stage kits coming down the pipe in the future. BOV will be a waste to change (lose performance) and tuning as already under development to allow modification with out freaking the ECU.

/end thread

 

Nope I haven't
This post was done from my experience with a similar 2.0T engine.
Tuning is gonna take a lot longer then many think.

Bump (because ive seen a couple of bov questions again)


and to think my engine was once considered "high output" compared to other turbo engines....
Now its the standard entry level 2.0T lol

 

Yes, tuning will be a bitch on this car. DI ftl for tuning.
