PING D16Y1 with P29 pistons and std head gasket

**alessioo** · 17-08-2011 07:39 PM

yeh i loved building this motor i did really have a good time cleaning it and putting it all back together.
76.5 mm pistons and had to get reliefs on the pistons for the valves.
a friend of mine had a wideband aem and we played around with it. mostly did base timing lower limiter and richened it up just while it was running in.
then i mucked around with it without the wideband just driving and tuning but nothing major.

70mm and sorry man it was 137 at the motor.

my goal with this car was to one day put it on stright gas injection and run some crazy comp like 15:1 or 16:1 and upgrade the rods.

if it was 137kw at wheels, itd b closer to 110kw more or less @ wheels.... but very good power for d-series

Yeah I thought about 120kw atw what more like what the yanks got from a build similar to your's. Still an awesome figure anyway.

Can I ask what it cost you to build? Can't wait to see your dyno sheets.

how much was taken off the head? and what kind of head gasket was used?

also size of the exhaust depends on flow output - not engine size
if the engine is making over 120kw than i would go for a 2.5"
my D15 is tuned at around 70-80kw with a 2.5"

as for the gearbox - try get a JDM D15b 5spd with OEM LSD - and have it installed with a Stage2 clutch and lightened flywheel

cost me 2 grand but tuning is going to bring me over 3000.

2 layer head gasket 0.025 and took 0.020 off the head and the valves just touched

dunno much about exhaust size will see what the dyno says and if i need a 2.5 ill change it.
i had the 2.25 exhaust with my d15b7 and it just had enough back pressure.

i wish i could afford a jdm gearbox. atm i got a lightened flywheel and a extreme heavy duty clutch
