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 …

The end of the beginning

Post  Jim7 on Sun Sep 19, 2010 4:37 pm

I couldn't think of a better title. I think I got the brakes, suspension, driveline right and yesterday mated the LS to the car. However even after modding the oil pan to the point the crank almost rakes the bottom I still don't have clearance between the the LS6 intake and TB to the hood and so I'm resigned to do something I didn't want to do. That is put a bubble in the hood, that or drop the crossmember, and I like that even less.

On the bright side. This past Wednesday at a lap day at Mosport I had the opportunity of riding along in a 7 litre ZO6 and I was blown away with the adhesion and acceleration. Folks familiar with my project suggested taking notes because thats where my project is going. Anyway nice to be back.

I know that dropping 1/2" on the cross member seems scary, but what is the reason you dont want to? cant you just build the suspension to compensate for the body lift in the end?

I am not knocking your idea I just was wondering the reasoning?

Buldging the hood wont be a breeze, but it can open up a new way of getting a clean air induction.

Welcome Jim! Where ya been?!?!

Whats the clearance between the oil pan and the crossmember? I had to cut my uprights and reweld them. As is, they caused the clearance to be close to an inch point five. So, after cutting them, I got the clearance down to 1/4".

Then, I spaced the crossmember down 1/2". Now, the throttle body clears nicely; but not my fuel rail covers. Laughing Also, check that the drivetrain is not sloutching back by checking the angle of the CV joints and the tbas on the torque tube and torsion tube. I noticed while mocking up my uprights that when I jacked up only the front of the car, the drivetrain slouched back on the soft tranny mount causing the engine to sit higher due to that angle difference on the uprights.

Which oil pan are you using? If you are using the Moroso, you have to space the cross member down 1/2" and then you throttle body might still need a slight grinding to get the clearance we like to see.
If you are using the moroso pan and you think you don't have to space the cross member down, Well you've been miss informed.

A friend of mine has an LS7 c6 Z06. I'm sorry to say that my car will never be half the car that it is. :/

Thanks for the advice. First, I'm in Burlington Ontario. The oil pan started as a Moroso and I channeled it down at the crossover to 1.75". The clearance issue as I see it is steering box and the rack mounting points. At this point I have a 1/2" between the OP and the crossmember. As far as the hood, I can probably remove a piece of the centre brace on the hood and that will find an inch of clearance. As far as dropping the crossmember I believe i'd also have drop the rear control arm mounts too?

Alot of us have dropped the front crossmember and havent had to deal with the rear. But I know the rear can be adjusted without dropping. Talk to Eric/ Admin. He is doing alot of these conversions for people through Texas Performance Concepts and he has alot of experience piling up for it.

How does dropping the crossmember affect the steering rod. Doesn't that have to grow to equal the distance of the drop? EDIT. I have custom control arms with spherical joints and a custom castor blocks and there's no give to them so if I drop the member then so goes the rear mounts. No big deal though.

As far as the steering rod goes, it still fits, It wont go anywhere once you have the cross member back in place. I drove about 200 miles and it didnt move.

I dont know how the custom front will affect the rear. Thats beyond my knowledge.

I don't think it's possible (read: reasonable) to NOT drop the crossmember. The throttle body would be .5" up into the hood at the least. You would have to put a bulge on the front of the hood, and cut all of the structure from the front center of the hood.

The back of the car doesn't require any changes for dropping the front. You're welcome to reinvent the wheel, but the crossmember drop is pretty much required if you ask me.

I had a good look at the problem today and I agree the crossmember has to come down. Right about now I'm patting myself on the back for going to the tubular control arms with heim joints. I have the engine suspended on a brace I had from the 944 days and tomorrow I'll cut some spacers to discover how low it's gotta go.

the kits all come with 1/2" spacers, are you going to try and keep below that or you just cutting 1/2"

I made this modification to make up for the 1/2 drop:

Pretty easy to do, except for the welding part (that cost me $50).

That is the lower corner of the crossmember, the hole is where the front of the control arm attaches.
