Post What happens: 2.2l block with 2.5 heads, no turbo

Okay, if you know the answer, let me know...

I am thinking about going turbo on my car, but I will replace the block with the 2.2l turbo block. Knowing this reduces the CR a lot (what, below 8:1?) would my stock MY2000 ECU be able to run the engine WITHOUT the turbo on it?

Read: When I have to smog it I may have to pull all the turbo stuff off to pass visual inspection, but it'll still need to run and pass tailpipe testing...

It'll be a slug! *lol* j/j, you'll be getting a C/R closer to between 9.0:1 - 9.2:1 You'll loose alot of torque, and you won't have much power being N/A unless you increase C/R and bump up the revs.

So the thing will run, that's good. Will the stock ECU be able to handle it? Or will it flood the engine and create excessive tailpipe emissions?

I don't think it will flood the engine because the ecu doesn't regulate fuel based on head size or anything, it regualtes it based on the pressure in the intake manifold, MAP, or by how much air is flowing the intake, MAF. But then when you put the turbo on you'll have to put on bigger injectors so it won't matter anyways, until you pull off the turbo, but then on the day you go you can use an afc to lean out your mix and the ecu won't have time to remap the fuel curve...? did I help any?

If you weren't in Cali with all those strict Inspectors, it would be a lot easier to swap out the dash with one of your buddys than it would be to take all the turbo parts off.

But unfortunately, you have to deal with those emmissions nazis.

Oh, that dash idea is a good one. Hm. Have to think about that. Maybe in 2 years you'll see me posting for someone with a white Scooby to do a dash swap!

Don't those inspectors in Cali check vin#'s on the dash as well as under the hood for the chassis vin and sometimes even the block?

I've heard some of the emissions places in Cali are real strict.

You need to register it in Michigan where there is no emissions test like I'm doing, hehe.
