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 …

LS3 OE Camaro / Vette Exhaust Manifolds

Post  240Z2NV on Mon Jun 20, 2016 7:23 pm

I'm still in Research Mode. Trying very hard to address any headaches from Referee for CARB Inspection beforehand ....
I did check Stickies, and unclear if they apply to MY platform. Generally, it seemed earlier iterations of LS motors. Mine will be LS3 Camaro or [Vette ?] OE Exhaust Manis & Cats. Has ANYONE TRIED to make them work in a 944 ?

Thanks in advance.

Oh, and did a TON of reading about Hydroboost, ABS , ..... Seldom do I see any SPECIFIC PART NUMBERS .... anyone ?

Look up the hydroboost for a 2000 Ford Mustang GT. You want the master cylinder and the hydroboost unit, i got these parts from Rock Auto. Some of the guys started using the original Porsche 944T master cylinder with the Ford hydroboost unit, i think TPC was selling an adapter for this. This lets you keep the original pedal feel and brake bias.

Come down to SD some time and id be happy to answer questions. Its easier than typing it all out Smile

I've been slowly building mine since october and I'm still in the research phase.   Very Happy

I don't know of anyone who has tried to make vette ls3 manifolds and cat's work. Sorry.

As Jon (technoduck) pointed out, many of the people on this board who run boosted brakes use the hydroboost system from a 99-2004 mustang. The complaint here is that the mustang master cylinder that attaches to this booster is improperly sized for porsche brake pistons; leading to a very touchy brake pedal. Two options to fix this: 

1. get after market brakes with piston sizes that more appropriately match the mustang master cylinder(people often don't do this because brake caliper adapters are few and far inbetween)

2. purchase an adapter block for $265 from texas performance that allows the factory 944 master cylinder to attach to the mustang booster allowing for a more factory brake pedal feel. 

After that you still need to mount the booster to the firewall at the correct angle (something like 12.5° up towards the sky but don't quote me). Many people make their own plates for this, or texas performance sells it for $75 or something (it's not on their website but if you call them they have it). After that you'll need to move the driver side coil packs for clearance. I think people have gotten away with using the tall truck mount system to get the necessary clearance. Then you'll need to redo the power steering lines. The hydroboost unit itself needs a little modification to fit the factory brake clevis to the brake pedal (cutting and tapping). 

In all it's a rather lengthy and somewhat expensive process. Something you're probably familiar with from your 240 experience  rabbit

If you go in to the sale items i have a brand new mustang HB unit with the push rod threaded for the porsche clevis for sale. I had to use the BMW system do to clearance issues.

Kevin, did you document your alternate route with the BMW unit here on the forum ? I'd love to read about it ...

Thanks ...
