Fiero GTS (GT Streched) Build thread Fast Back plus Nochie (Page 6/15) Nebraska DEC 23, 09:12 PM More progress, I got the engine/cradle in and about 95% of the wiring. I did hook up the battery and turn the engine over and verifed the fuel pump relay came on than off. Next I going to hook up a pc to the ALDL connector and verify the ECM is working and test some of the sensors. Whats left before engine fireup is: 1. Finish wiring. 2. Connect cooling system 3. Add temporary fuel tank 4. Finish exhaust system Since I have a extended Xmas break from work I plan on getting the engine running before the new year. bubbajoexxx DEC 23, 10:44 PM cant wait to here it is running and to you and your family Merry Christmas Nebraska DEC 24, 06:59 PM Merry Christmas to you too, Bubba Joe and everyone else on this forum. Nebraska DEC 28, 07:16 PM Update, I finished the wiring, or at least enough to start the engine. Still working on the exhaust system. I have the mufflers temporary mounted so I can route the exhaust. I got some exhust tips from a Cadillac and modified them for my exhaust, here is a couple of pics. Nebraska JAN 02, 04:19 PM I finally got the exhaust system done ! Here it is, pretty awsome ! Nebraska JAN 02, 04:21 PM What is more awsome is what was left over from two weld up header kits and two U bends from JEGS ! fireboss JAN 02, 05:18 PM quote Originally posted by Nebraska: now I have a MIGRAINE........... Nebraska JAN 04, 10:16 PM I got the Northstar running but I need help with the cooling system. I need to know which way does the coolant flow in and out of the Northstar. The coolant tube that is connected to the water log is the one that is getting hot. The one on the t-stat is cold. So it looks like its out of the water log (top of engine) and in to the t-stat. Can anyone confirm this. I read alot of Northstar build threads but came up with alot of conflicting and confusing info. Thanks! Nebraska JAN 05, 08:13 PM I think figured it out. I basically have the cooling system from the Cadillac. I went to the scrap yard today to look at the stock cooling system in a cadillac. I had everything correct except the main cooling lines, I had them swapped. Looks like the intake is at the t-stat and the output at the top of the water log. I would have thought when the cooled water came in over the t-stat that would cause it to close. The temperture seemed to be stable around 195. Once I get a couple of lose end tied off I will post i video with sound. I think it sounds exotic with the 180 degree headers. I'm currently trying to get the charging system working. Nebraska JAN 05, 08:35 PM Ok here is the video, it sounds alot better live. I can't wait to take it outside to see what it really sounds like.
