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 …

Making plug wires, running plug wires. I used MSD kit 31193 and substituted the MSD 3304 LS1 coil ends for the ones that came in the kit.

i was wondering if it was the ifc hood, but your pics didnt look like what i remembered the ifc hood looking like. reason i asked if it was the full hood or a skin is because you can buy them both ways. i already have a hole cut in my stock hood so i was thinking about getting the skin only and bonding it to the factory structure.

Did a little "while you are in there" maintenance last night. My fuel pump died a couple years ago and I replaced it, so that is still fine, but I've never changed the in-tank fuel screen since owning the car so I decided to do that while the tank was dry.

I also dropped the fuel pump to change the delivery fitting to -06 from metric in preparation for setting up the lines to run the Corvette style fuel filter/regulator which will replace the factory filter.

Started roughing out my intake situation. Built a little bracket to hold the intake pipe forward and up from the power steering pulley, there were 2 existing studs there I could make use of to secure the bracket. Please excuse the lack of hose clamps and filthy filter, the whole setup was in and out multiple times for fitting and the filter is just for testing space, I need to grab a new one.

Still some work to do, need to drill the pipe to place the AIT sensor and the hose barb for the PCV fresh air source.

Worked on the fuel return line tonight. First shot is under the rear hatch carpet, top of the fuel level sending unit where the return line goes in and the tank vent line comes out.

Attached a string to the old return hose before I pulled it out.

Shot under the car by the tank. The Corvette filter/regulator is being held by the original stock fuel filter bracket. I've got the delivery line to engine bay and the return line to the tank connected. Just need to do the line from the pump to the filter/regulator.

Finished up the hydroboost lines. I also drilled the manual headlight bracket on the driver side to give a lazy eye setting to get some air to the area where the air intake and hydroboost cooler sit.

Finished up the wiring. That's it for the install on the top side, except for installing the strut bar, hood and header panel obviously.

Next up is exhaust. Nothing too elegant planned there, I've got a Y pipe in hand and I'm waiting on a few other pieces to make the connection from the headers to the existing Lindsey Racing 3 inch single system. This will be the "get it running" setup, it only has a Pypes M-80 muffler which doesn't muffle much. It was fine on the stock turbo engine since the turbo did much of the muffling.

One step at a time Wink

Small update, had a friend weld up some exhaust pieces on the weekend to help me connect the headers to the back section of the existing Lindsey 3" system I was running with the stock engine. Winter is looming here, so I'd like to get it idling in the garage so I can chase down any startup issues and leaks or other problems. Wiring is not my strong suit so I doubt it will start up easily, get ready for a flood of questions soon!

Will your strut brace clear over the engine and under the hood?

I've already tested the strut brace over the engine, clears there. Hood should be fine, fit under the stock hood and the cowl hood has more clearance than stock.

OK, pieced together an exhaust system that will let me attempt to start this thing up in the garage over the winter. Headers into magnaflow Y into flex pipe with wideband sensor fitted into existing 3” Lindsey Racing exhaust out through Pypes M-80 muffler.

That exhaust is going to be incredibly loud. Like, not want to drive it on the street loud...

Oh for sure, it’s the same exhaust from the stock engine and it was unbearable on the street even with a turbo doing some muffling. It was fine at the track with ear plugs in and a helmet on, so I only have to put up with it for the 20 minute drive there and back. I can re-evaluate the muffler choice, but this will at least get it up and running hopefully.

I use spintech mufflers only. Very well built and very good sound.

Well, the good news. Got it up and running, no warning lights on dash, coolant and oil pressure guage work, revs read double so the MEFI computer must output a V8 signal so I'll need a conversion box to correct that.

Now the bad news. There was a strange tapping noise and low cold start oil pressure and unresponsive oil guage with revs which turned out to be the worst case scenario. The oil has enough metal sparkles in it to build another engine!

I gambled on a used engine and lost. That's life. Not sure I'll bother cracking open this engine, may just hunt for a fresh built long block, I'd like something around the 350hp mark so I can abuse it on track without having to worry too much about the transmission. Another aluminum 5.3 or possibly 5.7 long block. At this point at least its a more simple engine swap, everything around it is ready to go, wiring, fuel, cooling, accessories etc.

Dang, that sux. But, that is a gamble when buying used engines. Best bet is find another engine and do a rebuild on it. Then you know for sure what you have. You may even be able to rebuild your existing engine fairly inexpensively.

Well, the 5.3 is out and the 6.0 LS2 long block is in. The MEFI ECU went to the builder to be reprogrammed for the LS2 and was provided back with the long block. Still lots to do, but nothing in terms of “building”, mostly just assembling. When I installed the oil pan I used an Improved Racing oil pickup tube brace, so that’s different. I also rerouted the oil line to the remote filter housing which shortened it considerably and took out a bend. I also picked up an LS6 intake from a friend to use instead of the LS1 intake, that will hold me over until I figure out something better (Dorman LS2? FAST?).

I’ll either sell the 5.3 as a dead unit or crack it open and rebuild and use in another project, haven’t decided yet.

OK, primed and pressurized the oil system with an external pump to look for any leaks since I made a new hose when I rerouted an oil line to the remote filter housing which shortened it considerably.  Turns out the little right angle fitting I used to attach the stock oil pressure sender at the back of the valley cover wasn't sealing well and weeped oil.  So I replaced it with a straight fitting and all was good.  Because the LS2 style valley cover has a raised fitting built in for the oil pressure sender, you can't fit the stock 944 sender the way I had before with just an adapter.  So now I have the same M16 to M18 adapter and an M18 extension.  This raises the sender up enough that it doesn't interfere with mounting the intake.

Comparison shot of the underside of the LS6 intake I'll be running on the 6.0 vs the LS1 intake that came with the 5.3:

Silly question. Did you get the hydroboost system from TPC, and did the set come with all lines and connections for the hydroboost and steering rack ? I'm asking bacause I cannot get an answer from TPC.

Thanks
