12:1 CR

I thought you guys might be interested in my motor build (Nissan SRxxVE)
These pistons are for the VE head 90 mm with 16ve valve reliefs and are flat top.
The stock 16ve piston weighs 331g the 90mm ones below weigh 338g









They will be finished off with skirt coating and carrillo a-beam rods

 

those motors will make plenty of power.

 

what was the stock compression? those pistons look like they have a decent sized dome on em....

 

stock compression was 11:1 but it was 68mm stroke. These are 12:1 on an 86mm stroke

 

damn those look nice... What displacement?

 

90x86=2188 CC's or 133 C.I.

 

thank you sir

Where did you get this info? Did he post the stroke, all I saw was the bore?

Edit: NM... Reading owns me....

 

Are those off-the-shelf pistons? If not, did you go directly through CP? Any pics of the motor these are going in?

 

i will get pics of the motor tomorrow, it's torn down right now.

the pistons are custom from CP and i ordered them through Modern performance inc in NJ. I will be happy to post the invoice number if you want a set

The intake manifold im using is from the Nissan Pulsar VZR N1 it has 2 injectors per runner. I will be running a set of 333cc and either 370cc or 259cc depending on what i need.

keep us updated.

 

Would love to see some pics of the build up and engine.

90x86, lucky bastard

 

What is stock bore size? Is it a sleeved motor?

Its always fun to hear about other 4bangers that make good power N/A.

Stock bore is 86mm
It will be benson sleeved

I look to this forum to help me understand what it takes to make good NA power
Because of this forum i am running flat top pistons and looking at getting a custom header made

 

you have a good bore and stroke ...

its going to come down to cams and cylinder head ..

and a non restrictive intake and TB and a properly designed header ...

you put all those together and you will make good power
