Alex's B20VTEC DC2

Like cbauto said your compression will get bumped up ever so slightly.
If you havn't bought one yet might wanna look into it, but since your kit comes with a oem one, I would say don't worry about it, from memory a two layer is a 0.09:1 compression bump.

Have a look at that site I posted, you can list you can list your motor specs with head gasket size and it gives a approxamite compression ratio.

Also are you gettin ARP head studs?

As stated above, a tad bit higher compression, but will throw the timing out a little bit. You have adjustable cam gears though so that shouldn't be a problem.

Something I would consider is replacing the crank and rod bearings with something like ACL race bearings that can handle higher RPM. I'm not sure if the B20 stock ones are made to take high RPM abuse?

They are only around $150 and will save you huge headaches later.

Ill probs just stick with the oem gasket and save the hassle. And although b20 is still a strong motor yeah bearings would be a good idra.

yeh im getting arp studs, theyre included in the kit.

Higher compression.

Nice

Replace the bearing with ACL, might as well do everything as the motor is apart. It might take you longer in the end to complete your car...but at the end of the day... you wont have to worry about it.

do it once do it right.

what other plans do you have for the block?

As opposed to yourself?

Would I have to touch the cylinders or could I just swap out rods/pistons?

You can change pistons without machining the block. Not advised though

Id hone the block yea but I wouldnt have to bore it would I?

First of all, if you're doing bearings the pistons and rods don't need to come out at all. Just the crank.

But if you want to replace the pistons and rods then you might get away with a light hone if the bores are in good nick and the machinist knows what he is doing, but it's generally safest to go a tad wider on the bore and pistons.

Ill be doing rings aswell regardless of whether I do pistons/rods so wont they have to come out anyway

looking forward to see a b20 in your car
