pm7 pistons with stock rods in z6?
ok i want to build a high compression motor for my daily drive for just a little more power
my DD has 197k on it and at verry low revs when bliping the throttle slightly as the enging settles back and drops a little below normal idle i hear a slight rattle (low oil pressure @ low rpm.. little bit too much clearance on the old mortor..?) anyway would it be wise if i used the d16a1 piston and rod assembly like them rods not gonna come out the side of the block at 7400rpm clifs will i run into ROD failure ? d16a1 pm7 pistons and rods in a d16z6 thanks guys |

good choice on a mild sohc setup. i would rock it all day....

a ported and shimmed oil pump is going in with the mix and new pistons rings and a hone this time :1
you know jay.. the dirty b16 burnign oil!!! lol |

Guess and check when you have nothing else to go on.

Re: pm7 pistons with stock rods in z6?
i bet you the b16 has some fucked up rings and valve seals

Re: pm7 pistons with stock rods in z6?
I want to do the samething with one of the A6 blocks I have! >:D

Its been done a ton of times. The only problem is that you don't have to much quench(sp).
Edit its not really a problem, but not the best for making hp. |

they work pretty good nice bump in comp.

The only time bearings will rattle or knock is when they're toast. I almost got a b18b that made lots of noise before pulling - I helped pull it apart, and I noticed pistson #2 & 3 would hover 1/8" before TDC. How it still ran w/o seizing is beyond me.
With a MLS gasket, you'd end up with ~12:1 cr. You'd want to manually retard the timing a bit, or put in a modded P28 basemap with less timing. It might be a stretch on 87 octane. PM3 (D15) or PG6 (D16A1) pistons would get you in the 10-10.5:1 range, respectively, and up to 11.2:1 if you go crazy with a 1-layer head gasket, or mill the head. |

Re: pm7 pistons with stock rods in z6?
i will be tuning it myself!.. im thinking of reducing the timming by 30% everywhere and start from there

Mill the head best 50 bucks you can ever spend on a all motor D build.

Re: pm7 pistons with stock rods in z6?
Yep.

Re: pm7 pistons with stock rods in z6?
sohc zc non vtec
b16a throttle body modified to fit sohc zc intake manifold/ported manifold bolt ons 30 off the head zc/si transmission = b16a killer |
looking to do this myself
|
similiar project will be going on with my brothers 98 hatch, good luck
|
If you truely want a daily driven pump gas friendly build stick to 11.1 compression and you will be a ok
|
what ecu program will you plan on running?
|
does it have to be tuned
