Well I haven't updated this in a while and lots has happened over the last year or so
All seemed to be going well and with 95k on the clock I was rounding up parts needed for the 100k service. And....then it all went pear shaped. Head gasket started to go (pushing water into overflow) and then loss of power and finally lots of smoke....
. After doing a compression test I found the problem, #2 piston ring lands were gone. I kind of knew it would happen eventually so I wasn't that upset.
To save cost I decided to do as much of the work as I could myself. I had very little knowledge about how it all worked and thought this would be my best opportunity to learn. I took heaps of photos during the removal and bagged all the nuts and bolts separately with a description of where it came from. This saved so much hassle during reassembly!
Once it was all out and stripped back to the bare long block, off it went to Deshele Performance.
It was a slow build. What started out as "just a basic rebuild" snowballed into other things once I got into it. One thing lead to another and before I knew it the budget had doubled HAHA! But 11 months and 2wks later it was back on the road with a run in tune just in time for HVC 15.
The plan for this build was never outright power but reliability. Overbuilt and under stressed was my aim along with as much a factory looking engine bay as possible. I also set a few boundaries, it had to retain factory location/under manifold setup and a TMIC. It also had to run on 98 fuel as I drive this car most weekends, sometimes up to 800ks over a weekend of back road fun and didn't want the hassle of E85.
Build specs:
Deshele fully close deck block
JE forged pistons
Argo rods
Deshele 14mm headstuds
1mm stainless/inconel oversize valves
HD valve springs, titanium retainers
272 cams
DIY TGV delete (gutted and plugged std TGV's)
GT Pumps S03.5 turbo
ID1000's
AVO fuel rails setup parallel
AVO GR STI TMIC
Modified Zero Sports splitter to suit larger GR core
PW 72mm CAI
AVO 1pc inlet
Mishimoto X Line radiator
Mishimoto Fans
Mishimoto oil cooler
Saikou Michi duel catch cans
Air pump delete
Jim Berry 3800lb clamp clutch
Final tune by Silverwater Automotive came to 256kw on BP98 at 22psi. Very happy, drives great!
I can't thank Mark Berriman and Cam Johnson enough for all the help with removal and reinstall of the engine. Champions! Also a huge thanks to Brad and Garry Scott for all there help, advice and sourcing parts along the way.
