Tunner Cars

[2JZGOD]

Some of you might not know that i'm a car tuner at A-Tech Racing Tuner. I drive a 98 Toyota Supra with a 3.4L Stroker with a Greddy T-88 Turbo. Reccent dyno back in June of 07 was at 800 RWHP @ 794 ft lb of torque.
And post pics of your car love to see them if you want to see more pic of my car and my built engine check out my myspace www.myspace.com/carsbgone

Whats a Tunner car?

Seriously though, I have a 2007 Pontiac G5 and I want to turbo it in the future but they say you cant tune the 2.2L ECOtec so putting a turbo on would be a waste or possibly send the car into limp mode. Do you know of any tunes for the 2007+ 2.2L ECOtec.

pontiac made a prototype turbo for a 2.2 ecotec, theres lots of stuff you can do to them...if you really cant find anything for it, pm me and i'll link you everything i can find...a good place to start is rksport.com, they're a bit pricey though

[jimmythekid1]

you can turbo the ecotec but you need a custom PCM flash or a stand alone fuel controller.

[suicide_star]

not meaning to be a prick or anything, but do you realize the car that you're calling yours is like 2 or 3 different cars? unless you have 2 sets of sideskirts, 2 sets of front bumpers, 2 sets of mirrors...that you like throwing on your car.

w.tht pass movie ur gunna blow ur engine by the way u go really fast thn slo down cause ur putting too much pressure on ur pistons and u can blow ur engine

[texan_idiot25]

You can turbo the ecotech, look at the solstice GXP and Sky Redline. Dunno who said that you cant, must live in a hole some place. You can tune any engine, I could tune my mower for all I care too.



live4luck14-you dont know what you are talking about. Go, awaaay.

may I add if your going to turbo your G5 you will need to replace your rings with low compression or else you will blow your engine.

2jzs can handle piston pressure and not to be mean or anything, your pretty much completely wrong about what you said. You want more pressure for your pistons thats why they invented a TURBO.

They INVENTED a TURBO for more air to get into the motor faster and that cuases better gas mileage.

well if you putting in NOS and Turbo well yea you need low compression rings. You can't just slap in a turbo on a n/a engine you'll atleast blow the heads what a waste, low compression prevents you from blowing your engine. Only time they use high compression rings are N/A engines no turbo. In turbo they come stock with low compression rings.

heres my car.......

[tommygreen23]

I never said you can't turbo a ECOtec, I just said you can't tune my computer to tell it to add more fuel, air etc... The cobalt and G5 have completely new computers for 2007 and so far no one has been able to tune them without a piggyback, which I don't want. A stock ECOtec can handle 7-8 psi stock but any more than that and you will need to change out some internals. I know how to add a turbo, to use one efficiently you need a tune which right now I don't know where to get.

On a side note the GXP solstice uses a 2.0L ECOtec, The same one as the SS/SS cobalt, which is discontinued for 2008

Texan, I think were not on the same page, When I say tune I mean redoing the computer to increase performance, If your lawnmower has a computer it must be one bigass mower

And just for the record, no bigass muffler is coming anywhere near my car

I hope you can tell before and after.

-Ah, but I truely dont see how the ECU cant be tuned... Unless GM has done something to it in recent years.

-I tune it the old fashion way, CARBURATION, haha..

-Bleh, Saturn L-series. Been there, done that. Was glad when it left.

-The SS Cobalt used the Supercharged version though. But also ariel, makers of the Atom use that motor in its US verion, as opposed to Honda's VTEC motor. Same HP ratings at the 3 offered versions, but with more torque from the Ecotech.

ECU wise
OEM SPEC ECU thats garbage once you turbo it can't pass emission
Go for Motec Universal ECU to get Max HP

[tommygreen23]

Lucky no emissions here in Florida. The 2.4L ECOtec in the Pontiac G5 GT and Cobalt SS/NA or for 2008 the Cobalt "Sport" can be tuned and there are already several turbo kits out there for the 2.4. GM redid the whole computer system for most cars in 2007. There is a new radio, the black tie model, looks like this...

(sorry you cant see the whole thing...)

A lot of features are controlled by this radio, The DIC (those familiar with GM know what that is), Door chimes, and supposedly the ECU can be tuned by putting a CD in the radio (myth, some say that the dealer played a special CD in their car to fix problems.) There is also a second computer looking thing located under the dash on the transmission hump (yeah, there is still one there even though they are FWD) that wasn't there in 2006.

I know the Cobalt, G5, Ion, HHR and whatever other ones I'm forgetting have new ECU systems in them for 2007.

you lower the compression ratio because under full boost the presure raises so lower the compression stops the engine from coming apart.

Please explain low compression rings to me as rings have nothing to do with the compression ratio of an engine. Compression ratio is determined by the volume of the head and the profile of the piston.

nice sig but white MK 4 lives in Florida I live in WA how can we =? And didn't say I hate supra but I own a supra.
