HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

LS1 build foundation

Post  jayman1869 on Fri Jan 13, 2012 7:43 pm

posted this over on LS1 Tech but figured I would share here as well.

"Ok, so I went out and bought a 2000 LS1 out of a Camero, complete with harness, ECU and accesories. The motor has about 90k on it. Havent looked inside to see how it is yet.
This motor will be going into a Porsche 944 and I would like to bump the compression up just a bit.
As of right now, I will only be building up just the bottom end and will get to the heads and cam hopefully by the end of the year (slowly breaking the wife down).
This is my starting point:
I've read on here (LS1tech) that the stock crank is fairly stought, so it will be retained.
Wisco pistons - k398x3905 which obviously will mean to hone the block out (0.007ths over if I am correct, to a 3.905 displacement).
Eagle H-beam rods - crs61250
with new clevit and durabond bearings.
I was told that I could run this for a while, still giving the motor a little pep, while waiting to get heads and a cam to make my overall compression around 11.5-1.
Any advice, changes, discrepencies any of you have noticed or would be willing to add.
The car will be lite and my hopes are to have the motor push a reliable 425-450.
I was told that as long as I run 93 pump gas with this setup, I shouldnt have any issues.

Thanks in advance for taking a look."

FYI, the parts and info I learned about was provided to me by John at Texas Speed and Performance (LS1 gurus)

OK ..I spoke to a few people over at LS1tech.com. Apparently, the stock internals are fine to run with the power numbers I was looking for as long as the walls and pistons are in decent shape. It was stated that a re-ring may be my best option as long as everything looks good and I dont go forced induction.

Anybody got any thoughts on this?

The shop that did my motor said the stock rods won't hold up for long at 430hp. They upgraded mine to "H beam rods." They've done a bunch of engines but I'm sure mileage varies.

I'm curious about 11.5-1 on pump gas . . . . that goes against my very old hot rod days experience . . .

This depends on the cam. With the right cam the effective compression ratio will be low enough.

I will be running between 11:1 and 11.5:1 on mine. (Gen I w/aluminum heads)
