My compression results - Page 2

Excellent, thanks for the responses you guys. I'm pretty close to having enough to jsut go ahead and either throw in another stock motor or perhaps a ZC. My only question is this, is it possible and/or feasable to add a turbo onto a ZC motor on an automatic transmission? Thanks.

Hell yes it is, the turbo has no connection to the transmission....

Those are some sad results. I did a compression test on one of my cars today and hit 160 across the board except on number 3, which wouldnt even read.... I think the guage yawned at one point. I'm thinking I have a hole in the piston.... woofuckinghoo.

So I can put in a ZC and turbo and it won't be a problem? If so then I might just keep this car for a while.

Are you sure you did the compression test properly?

draybook · #21 03-13-2006, 09:19 PM

Yeah, my brother in law did it and he had just tested his Prelude so there was nothing wrong with the procedure or the tester.

Yeah, alot of people turbo ZC's its a pretty good combo actually, I dunno about how great it would be with an auto trans though..regarding power/shift and things..but iot would work, if your going to swap the engine you may as well do an auto/manual swap as well, it wouldnt cost much, and if your mechanically, and slightly electrically inclined you could pull it off with ease...this is assuming the engine you get has a trans (the cost part).

I'm thinking about getting the ZC motor for now and next income tax refund next year I could do the auto to manual swap and throw in the turbo.

Auto plus turbo is a decent combo. But there is more to it with a Honda, especially a ZC... Aren't DOHC ZC motors relatively high compression? Wouldn't this require more tuning? Either way, you're going to have to run high octane fuel.

FrodoGT · #25 03-14-2006, 01:27 PM

The ZC is not USDM, youd have to run high octane no matter what....Their standards are different and fuels have higher octane...

Here's a question. If I throw in a zc motor into my automatic, will I HAVE to use an auto pg7 ecu or can it be for a 5 speed?

duffman868 · #27 03-14-2006, 10:28 PM

it will need to be auto. you can runa auto in a 5speed but not the other way around

What should the average compression be on a 91 civic si? I got a reading of 75ish across the board. That was using a tester you screw in the sparkplug holes and crank the engine over.

Instead of starting a new thread i am bringing this one back.

I just tested my compression for the first time and i got 150psi in all cylinders. Is this good? By the way, my car has 241,700 miles on orig. engine and tranny. I used to burn a lot of oil until i put in some oil treatment.

It's a D16a6
