HEY DD74

THIS is my first post on pelican, however i'm a long time flat-6 membet, and a huge porsche guy..

anyways i have a very modified 2.7L, it's been storked and bored to 3.1L (3065cc), is running a custom CIS setup, has been blueprinted and balanced, heads were ported and stamp polished, JE forged pistons, some fancy connecting rods, custom grind crank with a extend lift S cam, SSI headers and a flowmater 60 series exhuast (very very loud)..

this engine is a monster, it rips apart axles shafts, requires ultra high torque starters (SKY high compression ratio), and guzzles gas... its not 300hp....but its getting damn close

and this thing doesn;t leek oil....though it does have less than 6000km's on it, and it taken care of like no other... and was a expenive build up to begin with

I'm not familar with stroking 2.7 blocks out to 3.1. I thought 2.9 was the most you could get out of a 2.7.

Also, I have a friend who had a 2.9, and at one time when he went for a DE, they wouldn't allow his car on the track as they thought the 2.9 was a liability for destroying itself.

As it is, this friend did track the 2.9, which made close to 300 hp, but the reliability factor was suspect; supposedly the engine became very hot only after a very few laps.

I can't speak to a 3.1, except that there exists a 3.0 motor that Porsche at one point in a manufacturing run, stroke out to 3.1. But 3.1 stroked from a 2.7? Wow!

I don't "hate" leaking motors, but I don't particularly enjoy them, either. I look at it as "character."

With that said, I'm fairly confident that with a twenty to thirty year old motor, particularly one that's not rebuilt, oil leaks are going to happen.

I've never seen them to be a big deal.

i believe the 3.1L (barely, almost half way between 3L-3.1L)
is obatined by boring to 2.9 or 2.8, and than stroking the rest...which is alos why the compression ratio is so high.

cheers

oh...i think i made a "new member post" which has links to my carodamin site, which has lots of pictures and the full sotry of my car...i'll check.. if not i'll make it asap
