Yup, The L42/L61/LAP/LE8/LSJ/LNF/LK9(the 2.0s and 2.2s) all use an 86mm bore. the LE5/LAT/LE9 (the 2.4s) all use an 88m bore.

2.0s have an 86mm stroke and long rods.
2.2s have a 94.6mm stroke and medium rods.
2.4s have a 98mm stroke and short rods

Glad I got a spare 2.2 block then.

^^ no, but theres directions of which wires to swap in my supercharger how-to

mrsilent13

oh ok that good to know.....ill have to find that

Maven

Actually, the answer is yes but you need to reposition some wires in the L61 connector for it to work

mrsilent13

yes i looked already thank you

Really....the intake, TB and SC will just bolt onto a 2.2L head?? Getting it tuned after that isn't a problem

Halfcent

You make it sound so easy.


Technically, yes, the parts will bolt right up. But you left out the pulley and belt, laminov water pump and heat exchanger, and induction.

However, yes, you can get a tune and make the whole thing work.

jlong3382

ya, I knew that....I was just suprised that physically it would bolt up. I had a 99 grand prix that I turbo'd. (It was a Bit**!). I did all the tuning myself. It only took me a year and a half to get it right

Sentry

I thought that all the models used the same valve springs/retainers.

Anyone want to clarify on this? I'm seeing only one part # for all three engines.

YellowLT

What years are you looking at cause I believe they were different 05-06 and then they made them all the same in 07+

Sentry

It says 05-07, so I dunno.

I know the valves are different, but I thought there was a difference in the whole valvetrain between the 2.2/2.4 and the 2.0.

All ECOs have the same size valves. You can swap back and forth to your hearts content,

CNG/Gas 2.2s and 2.4s have iron intake valves and stainless steel exhaust valves.

2.0s have stainless steel intakes and sodium filled stainless steel exhaust.

E85 2.2/2.4 have high silicon/chrome contet intake valves and stainless exhaust valves.

Sentry

I was really questioning the valve springs/retainers. I'm assuming they're all the same, correct?

Halfcent

Yes, correct.

Oh yes, L61, LE5, LSJ, LNF doesnt matter, they all use the same springs. Thtas why you want aftermarket ones.

Sentry

Oh, well I was just planning on going to aftermarket valves because I thought that since the LNF/LSJ springs were the same as the L61/LE5 that it would handle the power just fine.

What power level should the springs be replaced by? Keep in mind I'm keeping stock cams.

i have a question for you guys....
If I wanted to, could I do a complete motor and transmission swap with the cradle and everything on a 2.2 with my lsj 2.0? Will the mounts line up? I'm pretty sure the unibody's are the same right?

Halfcent

If you are keeping stock cams, then you don't need aftermarket valves really. Lets say you go forced induction. Then you would either want to get some matching cams or adjustable cam gears. That would then lead you to aftermarket springs.

Here's the basics. If you are increasing valve lift or engine RPM (8000 RPM or greater for the Ecotec), then you will need different valve springs. If you are increasing heat from the engine (like from forced induction, higher compression, whatever), then you might need better valves to dissipate that heat.

Yes, it physically mount up just fine. But you will never get it to work electrically. Read about ECM's and engine swapping. You can't do it on these cars.

ok, so if i stripped out the interior of the 2.2, put all my 2.0lsj parts interior, changed out the whole wiring harness to the entire car and just changed out everything, your saying I wouldnt have a problem? Im talking all the modules, airbags, wheels, suspension, steering components, engine, cradle, transmission, doors, dashboard, radio, everything...i could do it right? I hit a light pole in my ss and the frame is done...but it has alot of good parts on it. I want the beast back. I still owe 12,000 on it. I can buy a nice 2.2 for 5 grand right now. and jsut rebuild the ss from the ground up. And never pay insurance on an ss again...hey i didnt have insurance anyway, which is why im in this situation

Yes you could do that, but have fun. Much of that stuff won't have to be replaced.

Halfcent

Um, well, yeah, I supposed you could do that. But now you are getting into a cost/benefit ratio problem. The amount of work and expense involved would outweigh the result.

badboylb32

how do you figure? 5 grand for the new car, 2 months of work or less, and have my car back, or take my car to the dealer and have it fixed for 10 grand. ...or let the car go to waist and part it out. na to hell with that idea

Maven

Yes, you absolutely can take all the good parts from your SS and put them on an LS.

Assuming you have all the proper tools and skills, and a place to work, you should be able to get it done in a week of long days.(I think I could easily do it inside a regular work week(40hrs) if I dint have to put all the 2.2 stuff back in the SS) Youre going to need a new airbag contol module(SDM) if any of your airbags blew in the accident.

Just make sure youve got a plan of attack before you start this, dont just start tearing two cars apart, lol.
