My only question is can this kinda engine fit on a cavalier or cobalt.....? I know if its possible its going to required alot of other modding along with it like shift, clutch, keyhole, ECU, etc......lol......

To me that looks preety cool for an turbo engine......the ecotec 2.2 Turbo engine from turn key has been around for a few years so far. I think i'll look preety darn cool on a cobalt or a cava.

see ya.....



dude...

 

damn...thats pretty nice

 

WOW! Now that's a nice engine. The instalation of this thing might be a a little bit of a challenge. If you look, this thing hooks up vertical (look at the way the inner cooler is mounted) instead of being horizontal like the engine in your cobalt. This would dominate any street car if you could get it in!

 

The major problem is the parts,......thats require for this engine to work. If your car is allready AUTOmatic. Your talking about an upgrading ECU, a new entire transmission, shift, clutch, Ram hood etc........

So you kinda have to ask how much $$$ would come out of your pocket.......It can go both ways....

If you allready have an ECOTEC 2.2 engine, to mod would cost around 3,500 and up depending on the condiction of the engine, so for all though allready Owned Coupe and Sedan Cobalt, consider yourself lucky to look up on TURNKEY Engine. This engine Looks like it can put a stronghold. Good Luck looking into turnkey engines.....

see ya......



Dude....

 

These engines are not designed for drop in use on on J-bodys, Deltas, or any other production car with an ECOtec. They are rally car engines, dirty track stuff. They are designed to be used by custom built off road vehicles.

did you bother E-mailing Turnkey...? I`m really sure it can be done.....

See ya...



Dude....

 

I think the only REAL challenge to using that engine would be whether or not the turbo location and header configuration they are using will have sufficient clearance in the "J" or "A" body chassis....that and the whole illegal issue(custom burned stand alone ECM on an OBD2 vehcile)

it would obviously still bolt up....if you use an auto trans you would have to run a stand alone controller or convert it to electro-manual control(driver controls switches for the shift solenoids...this works but you would have no control over line pressure and therefore evry shift would be a maximum pressure shift....not that good if you planned to street drive this thing....a manual would obviously be the way to go)

the hot ticket ticket for this setup in my mind would to drop it into like a 93-95 S-10 pickup with a manual trans....no problem on underhood space....no OBD2 issues and these trucks are dirt cheap...

 

the thing is... thats not the exact same engine as the ecotec in the cobalt... but yea, a turbo cobalt would be cool. i was wondering if 2.2 might not have the better compression as the 2.0 has though.

 

Actually, if you go with forced induction, you should reduce the compression ratio. The 2.2L is a 10-1, the 2.0 is an 8.9-1. And that is really the only difference, a different piston. If you have too high of a ratio on a forced induction (anything above 9-1), you run the risk of pre-ignition and detonation.

 

so then what does a 2.2 owner do to reduce the compression ratio?

 

An E-management system...?

see ya........



Dude.....

 

The 2.0L LSJ actually has a static compression ratio of 9.5:1 not 8.9.....the only way to lower a static compression ratio is with combustion chamber or piston changes....however camshaft design greatly effects dynamic(running) compression ratio and this is far more important than static.....forced induction engine camshafts are uniquely suited to the additional atmosphere.

 

Correct, the 2.2 has 10:1 and 2.0 have 9.5:1 and also you are not quite correct about Forced induction and dropping compression. Depending on how much PSI you plan on running you can run in the safe zone and controlling it by proper fuel octane and ambient air temperatures it is possible to run high compression on moderate boost. A proper intercooler system/alk injection and proper tuning will out perform a 2.0 over a 2.2 as there are more cubic inches.

Also I have personally seen a V-8 w/11:1 compression and 15psi of boost run and run and run...

but you are correct in one aspect if you tune is off or your intercooler is not doing its part then you risk the chance of pre-ignition and detonation but the knock sensor is quick to back off timing to save the motor but I don’t like to depend on that damn thing always!

 

GM put a book out on turbo charging a 2.2 IT can be done and done quite well.
