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 …

LC9 5.3L anyone?
Hello all,
New here and I have the chance to scoop up a 5.3 LC9 (no, not LQ9), but I'm wondering if everything would work the same as if it would with the LQ9. It would be nice to have a V8 that's already tuned for e85.
If so, I think I'm going to pick it up.
Thanks!

Re: LC9 5.3L anyone?
It would be a truck engine so the intake, front end accessories and perhaps some other parts will need to be replaced or moved around. Also it has AFM (Active Fuel Management - a.k.a cylinder de-activation) along with variable valve timing. Those features may make it more difficult and costly to upgrade when it comes to aftermarket performance parts and ECU tuning. I have no idea on the availability of performance camshaft upgrades for this engine.
They do look to have solid power right out of the box at 320 crank hp on regular unleaded.

Re: LC9 5.3L anyone?
the cylinder deactivation isnt very hard to eliminate, if your using a factory ecm you can just shut it off in the ecm, if your going to go aftermarket you just dont hook it up. if you plan to go with a higher lift cam is is best to replace the lifters though. there are performance cams available that retain the vvt function, and myself, for a mild build, dont see a reason to eliminate it. if you do however choose to eliminate the vvt you need an ls3 timing cover, timing chain and sprocket, and of coarse the cam. also keep in mind that the timing cover is taller on the vvt engine, so converting from the truck accessories may be a bit harder. i doubt the short corvette drive will work, however the mid length f-body/gto stuff might work.

Re: LC9 5.3L anyone?
Thanks for the reply guys!
I used to have one of each year, of the modern GTOs, so I'm quite familiar with them already. That makes it all that much easier to do this build.
I think my biggest worry is swapping to the manual, since I've never done anything with transmissions before.

Re: LC9 5.3L anyone?
Alright, picked it up today. Once I get it home, I'll finally be able to start tearing it down and cleaning it up and replacing everything.
Re: LC9 5.3L anyone?
Hey Mark,
I've got a 5.3 in mine that put 330 rwh with a ls3 cam, long tubes and ls1 intake.
I'm putting a 54-426-11 cam and ls6 intake on now. I encourage you to upgrade the cam with the motor out as it's no fun to do later. Trust me, you'll wish you did.
The ls3, ls7 & ls9 cams make great power have manors and are cheep.

Re: LC9 5.3L anyone?
Thanks for the heads up. I'm totally planning on building it before I put it in. I have to do the AFM/DOD delete anyway, so I'll be doing that while its out.
I think I'll be doing a FAST intake though.
What did you do about the radiator?

Pardon the hijack, but will the LS1 / LS6 / Fast intakes fit with the DoD stuff in the valley?Patb wrote:Hey Mark,

Re: LC9 5.3L anyone?
Ls1 fits for sure. Even though I deleted the DOD I still used the cover. Now I have the ls6 cover with the pcv in it.
the way I drive the car a few times a month, it would never see enough easy driving to see any milage gains from DOD, so it's gone!

So what's the reasoning behind using the cover still?Patb wrote:Ls1 fits for sure. Even though I deleted the DOD I still used the cover. Now I have the ls6 cover with the pcv in it.

Oh I knew you needed the cover, just wondering why you didn't go with anything different.
Re: LC9 5.3L anyone?
Just noticed where you are. I used to work for a Hatteras dealer, been to New Bern quit a bit.
That's a great area to run around in one of these cars.

Oh nice, I photographed an 89 Hatteras Sport Fish not too long ago, for a client.
New Bern is a nice area, its just too bad that it's surrounded by not so nice areas.
