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 …

I started a thread in the 4.8/5.3 section but this section is more fitting. I bought this car for a great price, it sat for over 20 years because of a coolant leak. After I got it and ran the numbers it didn’t make sense to me to keep the original engine.

I’ve pulled the original engine, cleaned and sprayed the engine bay. I got a later model rack and converted it to manual. Fitted a tilton balance bar to the brake pedal for a dual MC. Got a griffin radiator that I’ll have to remove the filler neck to fit in place of the original. I got a fuse/relay panel for the engine and I’m adding relays for the headlights and fog lights.

I’m getting a 5.3 from an 03 1500 with DBW. I am going to convert it to DBC. I have a 2 piece bellhousing, s10 slave cylinder, C5 flywheel, and a Dodge D150 clutch kit. The clutch bolts up to the flywheel after drilling new holes for the dowels. I have a local machinist making the adapter plate and pilot bearing adapter.

I am making the motor mounts myself. Is it a bad idea to use the plans from this site to make the mounts from? For the exhaust I am going to make my own headers most likely. I’d like to explore some manifold options but there are no success stories yet.

Thanks! I’m trying to do as much as I possibly can to save some money. I’m picking up my torque tube adapter and pilot bearing adapter tomorrow. I actually got 2 sets made, one for me and one for my dad. I got the engine pulled, somewhat cleaned up. I’m going to modify the stock oil pan to match the milodon, and I will notch it for the steering rack. Got the radiator mounted,I had a few broken exhaust manifold bolts also.

85 5.3 swap Empty re: Fabrication of mounts and headers

Post  gwistrup Sat Oct 31, 2020 9:14 am

You have come to the right place for all the information you seek on fabrication of your motor mounts and headers. Dig around this site (do an advanced search) and you will find diagrams and measurements to make just about all of the conversion parts you will need. Be aware that most of these posts are from way back when LS conversions were relatively new and the aftermarket had not started providing these parts. The new items that you can buy may be improved over some of the original designs.
Greg Sloan wrote a 944 conversion manual years ago that has been superseded by the information in this forum.
A popular header conversion is modifying a Hooker block hugger header to fit the 944. I think the part number is 2312 or something like that. The passenger side fits perfectly but you have to cut and modify the driver's side. It's not that hard to do if you have good welding skills. The instructions on how to do it are in this forum. I have a set of those modified headers on my car and they work OK but they make any service on the driver's side very difficult if you use a hydro-boost brake booster. I plan on sending the money for a new set of headers this winter. I agree that they are painfully expensive.
Good luck, Gil

Made some good progress. Engine is in, headers are tacked up ready to finish weld, dual master cylinders finished and working, drive by wire pedal switch fitted to work with stock floor mounted pedal.

I made my own motor mounts, and poured the polyurethane in them. It was easier than trying to fit a bushing. I discovered that this oil pan works in the car, but I had to put 2 small dents in it to clear the steering rack. I did modify the original but I was fighting welding to the dirty aluminum and got fed up with it.

Put a cowl scoop on it (not for everyone, but it’s not everyone’s car lol) that will go well with theme when I get around to spraying the car. Truck intake didn’t clear and a Holley sniper didn’t clear, so I scored a LS6 off of eBay for it. I’ve played with the bin file in Tuner Pro RT and am pretty sure I’ve gotten the file ready to write back onto the PCM.

This is my first time making headers. They are not equal length I know. I am just happy they go in and out of the car. I used 1.75” 16 ga stainless.

Oil Pan,
