Yeah PRC still, it's under CAMS so you qualify
for many more events.
AMSAG is good & has more freedom in regards
to engines, but suspension mods are similar to
PRC still.

Yeah I just want to mount it on the wall
& look at it!!!
The cams I got made where re-profile std
cams, as no one makes new blanks.
The cam profiles where developed with JUN
Auto & my mate in Japan. So they aren't an
'off the shelf' item.
They where around $1200 plus the AUD$ is
shithouse now anyway

New CP pistons have arrived, bottom end can
now begin :)

Old vs New

Image

Compression ratio of 11.0:1, so more piston up top.

Image

A fair old weight saving too (not including the rings & bearings)

Merry Xmas mate ,
Yep CP have everything you need to get
pistons made for a g180W. They had never
made pistons for a G200W before. They
needed a sample & had to adjust some things
on the G180W measurements.

Yeah the pistons are 87.5mm, 0.5mm oversize.
They where made to my specs & around $1300.

The only conrods that are a direct replacement
for the G200W are the Spool conrods.
I used Carrillo Toyota conrods & they where $1300
too.

I went direct to CP, but SPOOL Imports have done
quite a few CP Pistons for G180W & have all of the
drawings for them.

With the ignition I think I will look at a SOHC 'G' series
dizzy or a Nissan Pulsar one to make fit.

Then I will run the MSD 6AL2 unit with the optical pickup
in the dizzy as what was on the old G200 SOHC.
It worked very well & had not one issue with it.
