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

will i run into ROD failure ?

d16a1 pm7 pistons and rods

in a d16z6

thanks guys

lock-pop!

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

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

i bet you the b16 has some fucked up rings and valve seals

I want to do the samething with one of the A6 blocks I have!

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.

valve seals no the gayDeeM b20 had no oil burning issues ring on the b16 yes
