to be perfectly honest i've been told different things. Sliding performance who i bought them off said they're 8.5:1 compression but i think thats with the head and block machined to their limits. Less machining lower compression

Wiseco pistons have a dish volume of -11.3cc's.

With a zero deck and a .051' thick gasket the compression works out to be around 7.18:1

Calculated with a combustion chamber volume of 63cc's and cylinder swept volume of 505cc's.

cheers 200. I know it sounds a lil low guys unless your running big boost or machine the head and block but these are still mass produced pistons used in plenty of worked engines overseas. If the compression is too low for your application it's easy to get longer rods which id reccommend upgrading anyway and take advantage of a set of cheap strong pistons.

.. no way, I was into my 3rd or 4th import skyline by then and had run up mid 10sec in my GTR by 2007.

... ah crap I feel old now!

    • Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!
    • Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!
    • I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
    • yeah, there's a country that recently started importing Skylines, I blame them.
    • I don't have a printer, but could at least attempt to make a printable model.
