Installed a rear strutbar today to add rigidity to the suspension. Unfortunately I had to do some cutting to make it fit so I used some rubber trim to make it look better.
Also got my new pistons and rods. These are 75mm Suzuki Vitara pistons.
These pistons fit, but are slightly lower compared to Honda pistons.
Lower pistons cause lower compression, which means lower power and longer spooltimes for the turbo.
That's why I chose to use custom longer rods specifically made for these pistons. Left is a piston/rod originally used in the Toyota 4efe engine. They share the same bore diameter and rod thickness, but the D16z6 engine had a longer stroke.
Nice difference in thickness! This should be able to hold my power goal.
8 or 9 years ago I turbocharged a Toyota Starlet with a TD04 turbo (found in the Subaru Impreza) but I didn't open up the block to replace my connecting rods as it was too expensive at that time. I had it tuned on the dyno at 193 horsepower but I popped the engine after 6 months. One of the rods snapped and it shot out of the bottom end of the block. Massive disaster.
I started stripping my engine here. I labeled all bolts/nuts and put everything in boxes.
