Thread: My pistons? lol

I bought the pistons that are in my motor in a hurry, and there's always something that I've wondered since. They are listed as 9.2:1 for a DET with 45cc head. What does that mean for me lol? What is my actual compression? Here's the link for my pistons though it doesn't have much info.


Race Engineering - Pistons

Nobody? Seriously?

i would think the same, the det and de head have the same combustion chamber

you should have 9.2:1 compression if you use the stock thickness headgasket and the head wasn't milled to much.

iirc de/det (non gtir) is 45cc, ve is 41.8cc and the gtir has something like 48cc.

should be the measurements of the combustion chambers in volume.

did those pistons come with rings and clips ?

Back when I got them I bought some rings they said would hold nitrous well. I don't remember anything about them now, but they said that piston/ring combo would hold all the nitrous I could ever throw at it.


I also paid $500 for the pistons back when I got them lol. Good price now.

Well there is no piston that will "hold all the nitrous you could ever throw at it"... I am curious what rings you used as well.

Lol don't even remember what they're called Rodney. As I said it was all purchased in a hurry to get my car back on the road. The pistons are made by CP for Race Engineering to their own specs. Explained to them what I was doing and got the setup they reccommended.


Btw I know as well that nothing is impervious, just went with there beliefs at the time lol.

LOL. BTW I saw the car last week in front of Sav-A-Lot in Columbia. It actually sounded good. You make that car out to be a piece and I like it. Hit me up next time you go to the track.

Yeah I actually put a somewhat normal muffler on it. Our new shop is up from there btw. I'm REALLY wanting to get the car dyno tuned finally this year. Sometime in Feb/March. As long as 43 is taken care of as good as it was the end of last year, I'll be going on a constant basis like I used to years ago. It'll take a while before I can drive it worth a **** though.
