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 …

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

Yes from TPC.  It came with all the hoses and fittings, however they were loose, as in I had to make the hoses myself by cutting appropriate lengths and attaching the hose ends. Also, I only have hoses and fittings for the braking system as I run manual steering, so no hoses go to my steering rack.

Chrenan -Thank you for all the photos and detail on your build, has helped me a lot! Couple of questions, for your oil/water gauges, how did you run the wiring? I am doing an 85.1 build, and noticed all the wires go into the computer. So my assumption is to run switched power to them?

Also heater "H," where did you put that, I see many putting it on the passenger fender next to the header?

Again, thank you.

Charles

Glad it’s helping Charles, I’ve relied on others here heavily so happy to give back.

Pretty simple on this one. One wire from the coolant temp sensor on the passenger side head goes to the 944 14-pin connector (the main harness connection near the brake booster). This sends a signal to the stock coolant temperature gauge. Two wires from the oil pressure sender go to the 944 14-pin connector. That sends a signal to the stock oil pressure gauge. That’s it. I can’t remember exactly which pins in the 14-pin connector, and they may be different between my car and yours.

I’m running vacuum to the HVAC controls so I can have ventilation defrost on track, however being a summer track car I don’t need heat. So in the interest of simplicity I’m running a loop hose on the LS water pump and no coolant gets sent to the 944 heater core.

LS2 in and started! Around 4 bar cold idle oil pressure (58 psi) dropping to around 3 bar (43 psi) once the oil warmed a bit. No bad noises. Still lots of little things to do, but a big step.

Chrenan,
Congratulations! nice video, so is that the same same exhaust you showed in the build or did you do something different? Reason I am asking, I am doing mine now, yours sounds very calm in the video. My approach to my exhaust is something that I can take to a track and not blow the decibels out, nice around town, and sleeperish, but will handle decent HP.

And thank you for the response on gauges, yes it turned out to be very easy.

Again - very nice build, I bet you cant wait to take it out for a shake out drive - please keep us posted, watching and learning.

Charles

Thanks Charles, I appreciate it!

Yes same exhaust as shown above, long tube headers into a Y pipe then a braided flex pipe connection to a 3” exhaust out through a Pypes M-80 muffler. Poor iPhone video sound aside, at idle it seems fine and not overly loud. I’ll report back once I’m able to really find out.

Radiator Question

Post  cazbah362 on Sun May 06, 2018 8:35 pm

Chrenan - quick question, I bought a radiator like yours from TPC, but was unclear on where to plug the hoses up on the drivers side from the tank. From what I can tell are the two small holes are a for the automatic cooler? and then there was a capped large hole? so how did you run your radiator hoses?

Sure. Passenger side is simple, top of water pump to top of rad and bottom of water pump to bottom of rad.

Driver side of the rad has three ports. The very bottom is the drain petcock. The very top is also a petcock which I don’t use, I just leave it closed. The other, larger, top port is 1/4 NPT threaded. I installed a hose barb fitting into this port then connected it to the bottom of the 944 Turbo expansion tank. (I just snapped some pics of this I can text or email them to you if you send me your contact info). I blocked the other large port on the 944 Turbo expansion tank - not required if you have a normally aspirated 944 expansion tank. I connected the steam vent line from the front of the LS to the small connection on the underside of the top of the 944 Turbo expansion tank.

Build Prcocess

Post  cazbah362 on Fri May 25, 2018 9:04 am

Chrenan,
Thank you for help on the radiator, once I got into it pretty simple - especially with your insight. My build is going well, except ran into a problem with the slave/throw-out unit leaking like a sieve. Since my car is a NA, I have a 5P transmission sitting around, so I will replace the slave and now install the 5P as well. Frustrating but life.

Also, when I start the car, the brake pedal goes to the floor? I have not bled my brakes since install, so I figure may be the issue. I double checked all the plumbing, looks correct and no leaks - so....

How is your build going? are you driving it yet?

Thanks for help.

Glad to help Charles. Getting closer with mine, was struggling with hard starting with mine, went through everything I could think of, sensors, fuel pressure, spark etc. All the basics and couldn’t solve it. Finally found a connection from my standalone harness that needed 12Volt while cranking and wasn’t getting a clean 12Volt when cranking. Fixed that and it starts much happier now! Need to clean all my wiring up now though as I really had to dig into it.

Was your slave new? Any idea why it spring a leak yet?

Chrenan - You have to love those wiring gremlins, they can be a pita, and happy you finally found it, I bet it lifted a load. So when will you get to take her out for a shakedown run? Two things in a build I love, firing the engine and taking her out for a shakedown runs.

As for the slave - not sure what made it fail. Yes, it was brand new from TPC? I could have banged it on something, could have been faulty? I spent a few night tightening fittings. Luckily I have the corvette bell housing that has the inspection cover. Tight fitting, but allowed me to rule out a loose fittings. I will start replacing that this week, I believe. Also - Kent of TPC was way supportive on this issue (and many more). He helped troubleshoot it and also is sending out a replacement. I need ti give him and his company huge plugs in this build, totally supportive and collaborative dude. THANKS KENT and TPC.

Also, I found out a FAST 102 will in no way in HELL fit under a stock hood unless you are willing to cut it, which I am not at this time. With that said, I ordered a stock LS6 intake to replace it. I see you changed intakes as well, what was the reason - more power? and what was your final hood clearance?

Again - thanks for helping, please keep posting - learning vicariously and with your help!

Charles

Switched to the LS6 intake when I got the LS2 long block, I figured it deserved a slightly better flowing intake. Actually just working on hood installation now. Should have lots of clearance as I’m using a Fiberglass cowl hood from IFC. Originally I was going to run without the cross member spacers, so I’d need a cowl hood for clearance up top. Everything fit without the cross member spacers, but the long tube headers were too tight to the floor for my comfort. So when I installed the LS2 I used the spacers, but I figure I might as well use the Fiberglass hood to save a few pounds anyway. Hope to be out soonish.

Hood Quality?

Post  Jchard944 on Thu May 31, 2018 7:55 am

Been poking around getting one of these hoods for some time now.

How did everything come together? A lot of rework needed or were you pretty happy with everything out of the box?

Car looks great by the way!

I've seen a few 944 fiberglass hoods in person, and I would rate this one very good. However, it is still a fiberglass body panel designed for a race car, if you are expecting OEM fitment you'll be dissappointed. I only had to trim 2 small areas by the wiper arms on the trailing edge of the hood, it was catching on the wipers when raising and lowering the hood, the interference could not be adjusted out with the play available in the hood arm mounting holes. I'm pleased with it, but my car has a lot of patina from sitting in the Japanese sun for most of its life. Rust free but sun baked it sort of its vibe, it isn't going to win a beauty contest so the hood doesn't really stand out Very Happy

Went around the neighbourhood a little bit then to the track for a few relaxed shake down laps.
