Hey guys,

I am planning to do a mini-me for my setup. My setup is gonna be a d15b7 with a z6 head. Whats my compression gonna be? Oh yeah, this going on my turbo setup. Will my compression gonna be too high for turbo? Thanks guys.

 

[PARAZZI]

can anyone help me out pls?

like 9.83:1. Also depends on what head gasket you are using

whats a good head gasket that I can use ? what do you recommend? thanks.

i would use the Y8 2 layer if youre going all motor. That would make it around 10.4:1

actually is going on my turbo setup...so i guess i am gonna need a lower comp. can you suggest any then? thanks.

It won't matter to much, jsut use a stock Z6 gasket and keep the power down. You won't be able to go over 200 anyway with stock rods.

Theoretically, with an OEM MLS gasket, it will be 10.22:1 (if I remember correctly). Obviously a lot of factors can affect this.

10.22:1 is fine for a turbo if you have a good tune and don't get too greedy for power.

How much power you plan on making ...I think you would be better off getting a 1.6 block if you want 200+...

yea how much power you wont then we can help you more

10.22:1 compression I heard this might be a bit too high for turbo? Or am I wrong? cause I heard between 9-9.5 is the preferable compression for turbo?

I would to get at least in around 220-250 ish range. Is this unreachable with a mini-me then?

9-9.5:1 is "preferable" because it's "easier" to tune. You can boost an 11:1 engine if you wanted to. Keep in mind that it's cylinder pressure that's making power, so with a higher compression engine, you won't need to run as much boost.

yes - your rods will not hold that much power

I have a b2/z6 mini me with high compression, currently maybe 120-125hp, I only want maybe 170-180 hp. Is that ok with my current compression? Would I just go for a smaller turbo and tune it well and it would be ok?

don't remove any layer from an OEM head gasket. they're designed the way they are for proper sealing. buy a cometic/aftermarket thinner one or have the head milled or install higher compression pistons, but don't run a "2 layer" gasket.

That should be fine... However, when you say "high compression", how high are we talking?

Well accordin to the compression calculators I found on here:

http://www.zealautowerks.com/dseries.html
and
http://www.knology.net/~jediklc/dcalc.htm

either 10.22:1 or 10.11:1

How does this effect my turbo set up?

 

[ddd4114]

As long as you have a competent tuner and don't get greedy, it should hold up.
