Though I should start a build thread for my race car.
Specs: motor g16 block, forged crank, rods, pistons 9.5-1 comp, gti head slight port work, 935c cams and cast flywheel to start with g16 sedan gear box with gti rear housing

Fuel will be e85 ecu is a haltech elite 1500, ls1 individual coils, electric throttle and ITB's

Body wise a set of coilovers and later strip the rear and add a rollcage and paint eventually

What forged crank are you using?

Why dont they just call it "Womenapause" instead.

I have always thought that a D15 crank in the G16 block with longer rods was a better option for rod/stroke ratio particularly if turboing.

The D15 main journals are too small for the G16 block,
The G16 block can either be line bored to suit D16 crank or the crank machined to suit. The 90mm stroke will work quite well with turbo,low down torque compliments the power curve depending on use. Also poor rod ratio gives piston speed at 8k rpm that a 1.6 4age has at 11k.

Build has changed a bit going to go turbo now on medium boost still will be using the Honda crank but will only be revving to about the 8500 mark
Phantom grip turned up for the diff so I'll be able to put that in soon and my coilovers also turned up so will be putting them in when I get time along with the new rear sway bar. Otherwise build is pretty quiet looking at a gen 2 gtx garret 2860 or 2867 for the turbo hoping for quick spool engine should be ready to drop in in about a months time and the can make up the intake and exhaust manifolds.

Your 935 cams will not be suitable for turbo Cultus +1mm extra lift seem to be a good option

I've got a set of turbo cams sitting in my cupboard already that I'm going to use instead

Do yourself a favor and lose the phantom grip had one years ago waste of time. a proper LSD really transforms the car.
