i have my jdm 3-stage head getting finished up this week...
port & polished and valve job...
but i'm not putting it on yet !!!
my turbo project needs considerable funding...
and i dont have a buyer for my fender jazz bass yet...
so in the meantime:
i'm on the edge of putting in a high compression setup
its stock bolt-on...no custom pistons or anything
basically
a vx head on a b7/b2 bottom
nice flat-top pistons and tiny *** combustion chambers
this yields on the old (inaccurate i might add) compression ratio calculators across the net @ 12.77:1
it should be close to that...but not exact
the old concept is that d15's deckheight is 207.45mm
the truth is they are all 207mm
new calculators should be sprouting about...if not already
i worried about detonation...
i'm not worried about spending more on premium fuel
someone like me who has been conditioned since 2000'ish to spending 1.30-1.50 a gallon driving 5000 miles a month...and who is now spending up around 2.75/gal ...
not to mention i've been putting the 93 in my car lately anyways because i dont think they even give 2 ****s about the quality of fuel they are separating in the towers and distributing...
its not a big deal for me to spend another $3 at the pump
i already feel pretty worked over by my gov...
maybe you have noticed in some of my posts...
lol
anyways...
thats the setup with a dx/lx 4.058 final drive tranny
hopefully i can get the intercooler up and running soon to help fend off detonation (yeah for the n/a setup)
all your bashing that its too high compression to run on street is welcome...
haha...i'm too adamant about at least trying it...
I bought a d15z1 and d15b8 this week. Both motors are partially disassembled. I was considering running the flt top 4 valve relief d15b8 pistons in my d15z1 to increase compression ratio but 13 is way high. I would like to increase my compression ratio from the 9.3 to 10-10.5 area. Any cost effective recommendations?
