well, after lots of threads made here, i've got it. EUREKA!

lets say i wanted to completely build/rebuild a motor and put it in my car, and piece together a turbo setup on the side until it was ready to go on...

would it be safe to run the motor without the turbo on it for a few thousand miles?

now, before you answer, here is the setup...

d16z6 block
y8 head (to bump the CR)
suzuki vitara pistons
hasting rings
eagle rods
sleeves (need reccomendation)
d16 trans
arp headstuds

im worried about two things:

-running that low of a cr for a daily driver... i know i can bump it by milling the head and getting flat valves. can you guys reccomend max milling, and a company that has flat valves

-will i have problems with the vitara pistons on the sleeves? i heard you should ONLY run forged pistons on sleeves... but im not sure if that is true or not. ALSO- can anyone reccomend sleeves and the price installed?

What are your power goals? More than likely the stock sleeves will be fine. I also suggest ditching the vitara pistons for some good forged pistons. You will be fine running your built motor withouth the turbo, that's how most people break their motos in.

dont go with those pistons they are NOT forged pistons.....

jbell

i know the vitaras are not forged. they still take a decent ammount of pressure though -can you reccomend any decently priced pistons... i know of cp, but its always nice to hear a second opinion. i think 10:1 pistons would be good, right? that would mean no milling, and no crazy valves

D21X

they only take so much pressure because the compression is so damn low!

low compression + high boost = high compression + low boost

jbell

so.. what compression would you reccomend if i am looking to make 250-300hp eventually?

ATS*Mark

so , stock civic pistons can handle the same amount as the vitaras.......its the rods that usually go.

Exactly, I'm sure if my stock honda pistons were super low compression they coudl handle more boost as well.

Not exactly. Low compression (9:1 would be good) and higher boost would be better for a daily driver on pump gas because it let's the turbo do the work and give you more room for error in tunig. High compression and low/high boost would be better for a track car on race gas and it has less room for error in tuning.

go 9:1 forged for the compression. if you are going to sleeve, check out z10. ive heard good things about their sleeving and they are pretty local too

cp i assume?
z10, i'll look into them. do they close the deck?

blackeg

i honestly do not know if they do closed deck. ill see if i can find out

blackeg

jbell, z10 does do closed deck sleeving. check out the website http://www.z10eng.com for more details

jbell

ok, so final word....

d16z6
quaife lsd
arp headstuds
running cp 10:1 compression pistons
eagle rods
some random sleeves that i havent decided on yet
hasting rings
new oem bearings...

this will be safe... no extra parts that i should/have to upgrade, right?

if you are on a budget with 250 -- 300 Hp range,
have you got a look into some supra piston ( they are forged )
with B16 rod's combo, a dude here on H-t.com sell those setup to put in a Z6 block ( or almost any 1.6 sohc Honda engine )
they allow you to take 1.2 bar of boost all day long, wich is enough to tapp your near 300 goal... they are not so honorous too... ( around 540 for the rod's and pistons )
anyway, search around more a bit and you'll find about this setup
the guy is called TurboPanda, I'll buy a kit soon from him so that's why I'm telling you about it...

hope this help !

Not knocking the point here and you are correct but the vitara pistons can hold more power mainly because of the treatment process done to them and also they have thicker ringlands..

jbell

what year supra pistons?
do they fit right on the b16 rods?

kranked91dx

No they don't, the supra pistons use a floating pin Style wrist pin, so the B16 rod's must be machined to fit them, also the b16 rod has to be machined to fit the D16 cranckshaft journal...

look with TurboPanda, he sell those kit and can give you some great advice, tech info about them, he run the setup for a long time...

nah, i rather just run the eagle/cp combo. no machine work, and they are forged.

still gonna have to notch out the block a little for the h beams to fit

kranked91dx

Well Supra pistons are forged dude!, anyway take a look at it, might save you a few dollar if you are on a budget.

i much rather run a notched block than a notched piston

kranked91dx

Sorry if I misspelled something but the pistons arn't notched dude, they are OEM Toyota supra piston, only the rod's need a few machining.

anyway search about them if your are interested... plenty info about them around here...

KRanked,

thanks for the heads up/info but what i was trying to say is, i rather notch my block, then notch/cut/machine part of my rotating assembly.
